The indulgence in willful persecution of sandstorm had made great attention of many countries around the world. Chinese government and the Chinese academy of science going with some other countries have devoted a large amount of vigor to study the crucial environment problem. Due to the main source areas of sandstorm all located in the arid and semi-arid regions where there have great area, hard natural condition and bad traffic condition, it's very difficult to accomplish source area and the reason of sandstorm. For this destination, a international cooperation organization has been established to clarify the occur mechanism, transfer process and the following environment impact of sandstorm. The organization includes many researchers come form USA, Japan, Korea, and so on. Beijing surrounding area is one of the main sandstorm sources in recent years. In order to understand fully of the sandstorm form and development, we analyzed the land use degradation of Beijing surrounding area during the last ten years. 71 scenes Landsat TM/ETM, 611 scenes DRG and DEM data had been processed in our study. This paper made a detail describe of using Landsat image data and high resolution DEM data to construe the soil erosion and vegetation degenerate. The result shows that the irrational human activities and land use style are the main factors of land use degradation. In case of Beijing surrounding area, the land degradation directly impacted the frequency and intensity of sand & dust storm in Northern China. The case study region of Beijing surrounding area includes 51 counties that belong to three provinces and autonomous regions.

Ontario Hydro decontamination experience

Ontario Hydro currently operates 18 nuclear electric generating units of the CANDU design with a net capacity of 12,402 MW(e). An additional 1,762 MW(e) is under construction. The operation of these facilities has underlined the need to have decontamination capability both to reduce radiation fields, as well as to control and reduce contamination during component maintenance. This paper presents Ontario Hydro decontamination experience in two key areas - full heat transport decontamination to reduce system radiation fields, and component decontamination to reduce loose contamination particularly as practised in maintenance and decontamination centres.

2015-06-01

Full Text Available Several studies have identified threats that originate in areas surrounding protected areas (PAs. While there have been various efforts to integrate PAs with their surroundings, considerable challenges remain. Here we summarize these efforts to date, discuss their effectiveness, and provide recommendations for future research. Based on a broad literature review of theoretical and applied approaches, we have outlined 68 models for balancing conservation and sustainable development in PAs. We comprehensively analyzed 23 of these models for integrating PAs with their surroundings. They were divided into two categories: area-oriented and process-oriented approaches. This review reveals the absolute necessity of combining these two approaches for future conservation and sustainable development of PAs.

Ontario's petroleum legacy : the birth, evolution and challenges of a global industry

International Nuclear Information System (INIS)

Gray, E.

2008-01-01

This book provided a historical account of Ontario's role in the global oil industry, from the coming in of the first wells at Oil Springs in the mid-19th century when the primary fuel sources were wood, coal, and water. In 1858, oil seeps in Enniskillen Township, Lambton County, Ontario revealed the existence of petroleum, which encouraged the first drilling of wells and the development of the global industry. The book explored issues related to imperialism, resource development, local history and the colonial land policies surrounding the oil boom. Details of the Petrolia oil discovery were included along with the accomplishments of the entrepreneurs who were instrumental in developing the petroleum industry in Ontario. The major elements surrounding the development of Canada's oil and gas industry were presented, beginning with the coal-oil-refining industry which paved the way for the development of the oil industry; the early oilmen from Oil Springs and Petrolia who drilled for oil; the development of the oil and gas industry's position today as a major strength of the Canadian economy; and the environmental and climate change issues that currently confront the industry. After 150 years, the oil fields at Petrolia and Oil Springs still produce commercial quantities of crude oil from at least 650 active wells. refs., figs

This, the second edition of the uranium-thorium deposit inventory, describes briefly the deposits of uranium and/or thorium in northern Ontario, which for the purposes of this circular is defined as that part of Ontario lying north and west of the Grenville Front. The most significant of the deposits described are fossil placers lying at or near the base of the Middle Precambrian Huronian Supergroup. These include the producing and past-producing mines of the Elliot Lake - Agnew Lake area. Also included are the pitchblende veins spatially associated with Late Precambrian (Keweenawan) diabase dikes of the Theano Point - Montreal River area. Miscellaneous Early Precambrian pegmatite, pitchblende-coffinite-sulphide occurrences near the Middle-Early Precambrian unconformity fringing the Lake Superior basin, and disseminations in diabase, granitic rocks, alkalic complexes and breccias scattered throughout northern Ontario make up the rest of the occurrences

Wetmiller, R.J.; Cajka, M.G.

1989-01-01

The northern Ontario seismograph network, which has operated under the Canadian Nuclear Fuel Waste Management Program since 1982, has provided valuable data to supplement those recorded by the Canadian national networks on earthquake activity, rockburst activity, the distribution of regional seismic velocities, and the contemporary stress field in northern Ontario. The combined networks recorded the largest earthquake known in northwestern Ontario, M 3.9 near Sioux Lookout on February 11, 1984, and many smaller earthquakes in northeastern Ontario. Focal mechanism solutions of these and older events showed high horizontal stress and thrust faulting to be dominant features of the contemporary tectonics of northern Ontario. The zone of more intense earthquake activity in western Quebec appeared to extend northwestward into the Kapuskasing area of northeastern Ontario, where an area of persistent microearthquake activity had been identified by a seismograph station near Kapuskasing. Controlled explosions of the 1984 Kapuskasing Uplift seismic profile experiment recorded on the northern Ontario seismograph network showed the presence of anomalously high LG velocities in northeastern Ontario (3.65 km/s) that when properly taken into account reduced the mislocation errors of well-recorded seismic events by 50% on average

Cogeneration markets in Ontario

International Nuclear Information System (INIS)

Poredos, S.

1993-01-01

Cogeneration offers a key strategy which supports global competitiveness for Ontario businesses, encourages energy efficiency and environmental protection, and offers natural gas utilities and producers stable long-term incremental markets. By supporting cogeneration projects, electric utilities will benefit from increased flexibility. Natural gas is the fuel of choice for cogeneration, which can in most cases be easily integrated into existing operations. In Ontario, electric demand grew along with the gross domestic product until 1990, but has decreased with the recent economic recession. The provincial utility Ontario Hydro is resizing itself to stabilize total rate increases of 30% over the last three years and supporting reduction of its high debt load. Rate increases are supposed to be limited but this may be difficult to achieve without further cost-cutting measures. Cogeneration opportunities exist with many institutional and industrial customers who are trying to remain globally competitive by cutting operating costs. In general, cogeneration can save 20% or more of total annual energy costs. Due to excess capacity, Ontario Hydro is not willing to purchase electric power, thus only electric load displacement projects are valid at this time. This will reduce overall savings due to economies of scale. In southwestern Ontario, Union Gas Ltd. has been successful in developing 40 MW of electric displacement projects, providing a total load of 5 billion ft 3 of natural gas (50% of which is incremental). Over 3,000 MW of technical cogeneration potential is estimated to exist in the Union Gas franchise area

The influence of weather and fuel type on the fuel composition of the area burned by forest fires in Ontario, 1996-2006.

Forest fires are influenced by weather, fuels, and topography, but the relative influence of these factors may vary in different forest types. Compositional analysis can be used to assess the relative importance of fuels and weather in the boreal forest. Do forest or wild land fires burn more flammable fuels preferentially or, because most large fires burn in extreme weather conditions, do fires burn fuels in the proportions they are available despite differences in flammability? In the Canadian boreal forest, aspen (Populus tremuloides) has been found to burn in less than the proportion in which it is available. We used the province of Ontario's Provincial Fuels Database and fire records provided by the Ontario Ministry of Natural Resources to compare the fuel composition of area burned by 594 large (>40 ha) fires that occurred in Ontario's boreal forest region, a study area some 430,000 km2 in size, between 1996 and 2006 with the fuel composition of the neighborhoods around the fires. We found that, over the range of fire weather conditions in which large fires burned and in a study area with 8% aspen, fires burn fuels in the proportions that they are available, results which are consistent with the dominance of weather in controlling large fires.

Ontario is not ready to face a large-scale nuclear accident

International Nuclear Information System (INIS)

2017-07-01

On paper, in Japan as elsewhere, nuclear emergency plans are based on international standards and all look similar. The counter measures are sheltering, potassium iodate prophylaxis, evacuation and control of foodstuffs. With 18 nuclear reactors to produce electricity and a research reactor, Ontario should be especially well prepared. Moreover, in USA, there are six power plants located at less than 100 km from the Canadian border. Would Ontario do better than Japan in case of a severe nuclear disaster? Ontario is not ready to face a severe nuclear accident and the population surrounding nuclear power stations are at risk. The large number of inhabitants will hamper protective response actions. Consequently, Canadian authorities keep lax protective action levels. Using more stringent levels would mean to extend the protection zone that would include a too large number of persons. Canadian authorities should openly acknowledge that a severe nuclear accident could happen in Ontario like in any other country and trigger a complete reorganisation of emergency preparedness and response (EP and R) to cope with such a possibility. New response plans should be defined with the involvement of stakeholders

Politics of environmental regulation: acid rain in Ontario

Energy Technology Data Exchange (ETDEWEB)

Hogarth Wood, G P

1984-01-01

This study looks at the case of the Ontario government and Inco Limited in order to explain political responses to the acid rain issue and to generalize about the dynamics of environmental regulation. Existing accounts of the acid rain situation neglect a systematic explanation of the political processes that guide the selection of policy. This reflects a tendency in Canadian public policy analysis generally. Most literature in this field is both apolitical and atheoretical. In addition, most models of public policy focus attention on a narrow range of policy determinants, making the models inappropriate as exclusive guides for public policy analysis. This study follows an approach that assumes that no variable can, a priori, be viewed as the primary determinant of a policy choice. Instead, relevant features of the economic, social, and political environment surrounding the policy process have to be examined in addition to that process itself. Accordingly, a number of potential influences on the acid rain policy outcome in Ontario are explored: the economic structure of Ontario, political-geographic factors, the role of science and technology, political power in the province, political values and attitudes, the institutional structure of Ontario politics, and finally, the policy process itself. This exercise points to the overriding influence of the political system environment, particularly the economic structure of the province, in explaining the policy choice. The findings of this study can be extended to explain regulatory responses to the issue in other political jurisdictions.

2002-01-01

The market structure of the Midwest Independent System Operator (MISO) for the electric power grid was described with reference to physical bilateral markets, multi-control areas, and MISO services such as security coordination, congestion management, billing, generator interconnections, tariff administration, energy imbalance, market monitoring, and electronic scheduling. The drivers impacting MISO development include MISO-PJM-SPP common market initiative, the FERC Standard Market Design initiative, the integration of alliance companies with MISO, and the division of functional responsibilities between RTOs and ITCs. The characteristics of the Michigan market were described, along with participation in the midwest (Ohio and Michigan) wholesale and retail markets. It was noted that in order for Ontario to sell to the midwest, the Ontario market design would need a successful export bid each hour to get power out of the province. Sales of ancillary services from Ontario-based generation are not permitted in the initial Ontario market design. Energy and transmission is currently bundled in Ontario tariffs. 1 fig

To investigate the distribution pattern, species diversity and community structure of fleas on small mammals in the surrounding area of Erhai Lake, and the relationship between fleas and their hosts. Different geographical areas surrounding the Erhai Lake in Yunnan were selected as investigated spots. Small mammals were captured with baited cages. The cage-traps were examined and re-baited each morning. All fleas on the hosts were collected and identified. The richness (S), evenness (J'), diversity index (H'), dominance index (C'), total ectoparasite infestation rate (Rpt), total ectoparasite infestation index (Ipt), and constituent ratio (Cr) were used to measure the community structure. Altogether, 3,303 small mammals and 3,243 fleas were collected. From the 21 species of small mammal hosts, 13 species of fleas were identified. In southern area of the Lake, the species richness (21 species of small mammals & 12 species of fleas) was highest among the three selected areas. Seventeen species of small mammals and 8 species of fleas were found in eastern area, and only 13 species of small mammals and 7 species of fleas found in the west. This implied the probable influences of ecological environments on the fleas and their corresponding hosts. The community structure of fleas on small mammals was complex. The species diversity, species composition, community structure and distribution pattern of fleas were simultaneously influenced by the hosts' body surface microenvironment and the macroenvironment (habitat). The fleas are commonly distributed in small mammals in the areas and their communities are related to host species and the habitats.

Faregh, Neda; Leth-Steensen, Craig

2009-06-01

Legalized gambling in Canada is governed by Provincial legislation. In Ontario, the Ontario Lottery and Gaming Corporation is responsible for all aspects of gambling in the Province. There have been a number of recent lawsuits against this Crown agency of the Government of Ontario by gamblers, most of which have been settled or otherwise resolved. A recent class-action lawsuit on behalf of thousands of Ontario gamblers against this agency raises a number of interesting questions regarding the issue of responsibility and liability. The questions surround the issue of self-exclusionary practices of gamblers who deem themselves in need of external intervention in order interesting questions regarding the issue of responsibility and liability. The questions surround the issue to abstain from further gambling. A contract is voluntarily signed by the self-excluding gamblers whereby their further attendance at gaming venues is prevented and could be punishable by law. Where the gaming venues have failed to enforce the terms of this contract, gamblers have continued to gamble at these establishments. The class-action lawsuit stems from the grievances of these self-excluded gamblers who were not turned away. Relevant psychological theories and recent findings pertaining to gambling are reviewed and questions relevant to these grievances are discussed in favor of government responsibility and liability toward gamblers.

2017-01-01

The United States and Canada agreed to restore the chemical, physical, and biological integrity of the Great Lakes ecosystem under the first Great Lakes Water Quality Agreement in 1972. The lowest reach of the Genesee River and the Rochester Embayment on Lake Ontario between Bogus Point and Nine Mile Point, including Braddock Bay, were designated as an Area of Concern (AOC) due to effects of contaminated sediments and physical disturbance on several beneficial uses. Following sediment remedial efforts and with conditions improving in the AOC, the present study was conducted to reevaluate the status of the benthic macroinvertebrate (benthos) beneficial use impairment (BUI). Benthic macroinvertebrate community assessments and 10-day Chironomus dilutus bioassays were used to test the hypotheses that sediments within the AOC were no more toxic than sediments from surrounding reference areas. The study was separated into three discrete systems (Genesee River, Lake Ontario, and Braddock Bay) and non-parametric analyses determined that a multimetric index of benthic macroinvertebrate community integrity was significantly higher at AOC sites compared to reference sites on the Genesee River and in Braddock Bay while AOC and reference sites on Lake Ontario did not differ significantly. Survival and growth of C. dilutus were also similar between AOC and reference sites for each system with the exception of significantly higher growth at reference sites on Lake Ontario. Results generally indicated that the condition of benthos and toxicity of sediment of the Rochester Embayment AOC are similar to or better than that in the surrounding area.

Ontario Interns Fight Back: Modes of Resistance Against Unpaid Internships

Directory of Open Access Journals (Sweden)

William Webb

2015-09-01

Full Text Available In this article I report on three ways that interns and those sympathetic to their plight are opposing unpaid internships, focusing on the Canadian province of Ontario as a case. First, I analyze the ways that interns engage in social activism to raise awareness about problems with unpaid internships. Second, I examine several lawsuits that interns have waged against companies in an attempt to secure back pay. Third, I analyze the Ontario Ministry of Labour’s response to the growing concerns surrounding unpaid internships, and recent proposals that aim to strengthen governmental regulations. Arguing that possibilities for change have arisen largely due to the efforts of interns themselves, I conclude each section by noting some of the strengths and limitations afforded by each type of resistance.

Summary of Ontario Hydro's 1990-91 zebra mussel research program

International Nuclear Information System (INIS)

Claudi, R.; Wiancko, P.M.

1992-01-01

Ontario Hydro is the principal supplier of electricity to the Province of Ontario. It serves 3.6 million customers, with an inservice capacity of 28,200 MW. Ontario Hydro has seven fossil, five nuclear, and four hydraulic stations in the Great Lakes Basin and surrounding watershed. In addition, there are another 60 inland hydraulic stations and numerous dams. As the largest single user of raw water from the Great Lakes Basin, Ontario Hydro recognized the need to control zebra mussels early in 1989. At that time, very little was known in North America about the zebra mussel life cycle and potential impact. European utilities were consulted, but as we now know, zebra mussels are not perceived to be a problem in Europe at this time. To satisfy the immediate need for control, chlorination was identified as the most effective interim measure to prevent the fouling of systems which draw water from the aquatic environment. Due to the current regulatory environment, this solution is considered short term and Ontario Hydro was compelled to initiate a comprehensive research effort aimed at providing alternative methods of control. Most of the research effort during 1990, was methods of control. Most of the research effort during 1990, was directed towards this goal. Many alternative control measures, both chemical and nonchemical were considered. Also considered were the potential effects of the control measures and zebra mussels on station operations. A multidisciplinary team involving aquatic biologists, chemists, corrosion specialists, and civil and mechanical engineers from the various departments of Ontario Hydro was asked to address the problem. Some of the research also involved collaborative studies with universities, US utilities, American Water Works Association, and Canadian industries. Following is a summary of the research effort in 1990, and a preview of the research underway in 1991

A used lead acid battery smelter generates particulates containing lead that can contaminate the surrounding environment area. Lead is a heavy metal which is harmful to health if it enters the human body through soil, air, or water. An identification of lead in soil samples surrounding formal and informal used lead acid battery smelters area in Banten, Indonesia using EDXRF has been carried out. The EDXRF accuracy and precision evaluated from marine sediment IAEA 457 gave a good agreement to the certified value. A number of 16 soil samples from formal and informal areas and 2 soil samples from control area were taken from surface and subsurface soils. The highest lead concentrations from both lead smelter were approximately 9 folds and 11 folds higher than the reference and control samples. The assessment of lead contamination in soils described in C f index was in category: moderately and strongly polluted by lead for formal and informal lead smelter. Daily lead intake of children in this study from all sites had exceeded the recommended dietary allowance. The HI values for adults and children living near both lead smelter areas were greater than the value of safety threshold 1. This study finding confirmed that there is a potential health risk for inhabitants surrounding the used lead acid battery smelter areas in Banten, Indonesia. (paper)

Zhang, R; Kashima, Y; Matsui, M; Okabe, T; Doi, R

2001-07-01

Total mercury in the muscles of three fish species was analyzed in fish caught in Tokyo Bay and the surrounding sea areas, Sagami Bay and Choshi. Tokyo Bay is a semi-closed sea area surrounded by Tokyo, Kanagawa and Chiba prefectures. Sagami Bay and Choshi are open to the Pacific Ocean. A total of 412 fish consisting of northern whiting (Sillago japonica), flatfish (Limanda yokohamae) and sardine (Sardinops melanosticta) were caught in these areas over a 6 months period from November 1998 to April 1999. Total mercury concentration ranged from 0.008-0.092 microgram/g (wet wt.) in northern whiting, 0.006-0.065 microgram/g in flatfish and 0.001-0.045 microgram/g in sardine. All concentrations were below the restriction limit of fish mercury in Japan, 0.4 microgram/g of total mercury concentration. A significant correlation was found between mercury concentrations and body length or body weight in northern whiting and flatfish, irrespective of the sea area. A correlation was also found between mercury concentration in fish and their feeding habits: among the 3 species caught in the same area, crustacean feeding northern whiting had the highest, polychaete feeding flatfish moderate, and plankton feeding sardine had the lowest mercury concentration. In a comparison of mercury concentration in the same species caught in different sea areas, a higher concentration was noted in fish caught in the semi-closed sea area of Tokyo Bay, than in fish caught in the open sea areas of Sagami Bay and Choshi. This difference was most marked in fish caught at the bottom of Tokyo Bay and we considered that the mercury concentration of seawater and sediment in these areas was the cause of mercury accumulation in fish. These findings suggest that improved water quality control and environmental monitoring is necessary in semi-closed sea areas such as Tokyo Bay.

Ontario energy review

International Nuclear Information System (INIS)

1990-03-01

This publication provides a review of the developments in Ontario in relation to the national and international energy scene. Ontario is the largest energy consumer in Canada and is highly dependent on external energy sources. Several developments have significantly altered the Ontario energy scene. Oil and gas markets have become deregulated and market forces increasingly determine prices. A free trade agreement with the United States makes Ontario even more affected by international markets. Oil and gas prices have fallen from the high levels of the 1980s, but energy efficiency and conservation continue to be extremely important because they affect economic performance and the environment. In the next few years the greatest challenges will be to continue improving energy efficiency, to reduce the impact of energy on the environment, and to ensure the availability of sufficient energy supplies for future needs. This review contains statistics on energy in Ontario and explains them for the non-specialist. (7 tabs., figs.)

Ontario Hydro relies heavily on nuclear power. Nuclear fuel was responsible for approximately 34% of Ontario Hydro's energy production in 1983. The nuclear proportion was supplied by twelve operating units located: NPD, Douglas Point, Pickering A and B. It is expected that by approximately 1992, 65% of the total energy needs will be generated through nuclear power

The "rural pipeline" suggests that students educated in rural, or other underserviced areas, are more likely to establish practices in such locations. It is upon this concept that the Northern Ontario School of Medicine (NOSM) was founded. Our analysis answers the following question: Are physicians who were educated at NOSM more likely to practice in rural and northern Ontario compared with physicians who were educated at other Canadian medical schools? We used data from the College of Physicians and Surgeons of Ontario. We compared practice locations of certified Ontario family physicians who had graduated from NOSM vs. other Canadian medical schools in 2009 or later. We categorized the physicians according to where they completed their undergraduate (UG) and postgraduate (PG) training, either at NOSM or elsewhere. We used logistic regression models to determine if the location of UG and PG training was associated with rural or northern Ontario practice location. Of the 535 physicians examined, 67 had completed UG and/or PG medical education at NOSM. Over two thirds of physicians with any NOSM education were practicing in northern areas and 25.4% were practicing in rural areas of Ontario compared with those having no NOSM education, with 4.3 and 10.3% in northern and rural areas, respectively. Physicians who graduated from NOSM-UG were more likely to have practices located in rural Ontario (OR = 2.57; p = 0.014) whereas NOSM-PG physicians were more likely to have practices in northern Ontario (OR = 57.88; p education was associated with an increased likelihood of practicing in rural (NOSM-UG) and northern (NOSM-PG) Ontario.

1990-01-01

In the Ontario new housing market, Ontario Hydro's goal is to reduce the demand for electricity, increase the utility's visibility in this market, and increase customer satisfaction. Analyses have demonstrated that it costs less to construct new houses according to R-2000 insulation standards than to install new power production and transmission facilities. Research has also shown that R-2000 houses have better air quality and energy efficiency than ordinary houses. Nevertheless, most home builders have little enthusiasm for R-2000 houses; the strictness of airtightness standards, the slowness of certification, excessive paperwork, and a lack of promised marketing support are cited as the reasons for this. Ontario Hydro and builders' associations have signed a cooperative agreement for certifying new houses with the object of self-financing the program. The program intends to see construction of 1,000 R-2000 houses in 1990. To carry out this objective, some elements have been added to Ontario Hydro's marketing program in order to make potential customers aware of the advantages of the R-2000 house. Field staff will receive rigorous training in order to prepare them for helping the diverse types of builders. A mail campaign, focusing on areas not served by natural gas where significant numbers of new houses are being built, intends to bring home builders and buyers together. In February 1990, Ontario Hydro signed agreements with four major housing manufacturers to construct a significant proportion of the R-2000 housing stock

1994-03-01

An aerial radiological survey was conducted during the period of September 10 to 18, 1990, over a 40-square-mile (104-square-kilometer) area surrounding the Millstone Nuclear Power Station (MNPS). The MNPS is located on the Long Island Sound shoreline, three kilometers south of Waterford, Connecticut. The purpose of the survey was to measure and document the terrestrial gamma ray environment of the plant and surrounding areas. A contour map showing radiation exposure rates at 1 meter above ground level was constructed from the aerial data and overlaid on an aerial photograph and a United States Geological Survey map of the area. The exposure rates within the survey region are quite uniform. The area is characterized by an exposure rate of 10-12 microroentgens per hour including an estimated cosmic ray contribution of 3.6 μR/h. This is typical of natural background. The only exception to the natural background readings is the Millstone station itself, which is characterized by an exposure rate consistent with the standard operation of the reactor units. Radionuclide assays of soil samples and pressurized-ion-chamber gamma ray measurements were obtained at five locations within the survey boundaries. These measurements were taken in support of, and are in agreement with, the aerial data. The radiological environment near the plant is consistent with normal plant operation

2002-01-01

On May 1, 2002 both wholesale and retail electricity markets in Ontario were opened to competition. Wholesale electricity market sales of 150 TWh were valued at over $11 billion with 27,500 MW in service installed capacity and 4,000 to 6,000 MW import/export capability with strong interconnections to the Quebec, the Midwest and the Northeast. The key players in Ontario's electricity market are the Ontario Energy Board (OEB), the Independent Electricity Market Operator (IMO), Ontario Power Generation, and Hydro One. The OEB regulatory framework includes licensing and front line, daily monitoring of whole sale market. Serious capacity problems in Ontario have manifested themselves in tight supply and demand situations and highly volatile prices. The paper included graphs of available reserves for 1996 to 2002, HOEP trends and frequency, HOEP comparison, and a sensitivity to demand forecast. 1 tab., 6 figs

Ontario electricity rates and industrial competitiveness

International Nuclear Information System (INIS)

2006-01-01

Industrial electricity prices in Ontario rose significantly after the opening of the competitive Ontario electricity market in 2002, thereby widening the gap between industrial electricity prices in Ontario and those in other Canadian provinces. Navigant Consulting Ltd. conducted this study at the request of the Association of Major Power Consumers in Ontario (AMPCO) to research and compare current and historical electricity prices in Ontario and other jurisdictions in North America. The study provided an independent analysis of how industrial electricity prices in Ontario compare to those in other jurisdiction in which AMPCO members operate. It also formed the basis for comparing the impacts of electricity policy on the economic competitiveness of major power consumers in Ontario. The relative electricity intensity in the United States, Ontario and other Canadian provinces was reviewed for specific industries, including forest products, steel manufacturing, petroleum refining, chemical manufacturing and cement manufacturing. Publicly available aggregate data from Statistics Canada and the United States Bureau of the Census was then used to compare average electricity prices for industrial customers in Ontario. The data confirmed that Ontario has experienced a decline in its competitive price advantage in industrial electricity. Delivered industrial electricity prices in Ontario have increased by more than 60 per cent since 2001. Industrial electricity prices in Ontario rose above those in Quebec, Manitoba, British Columbia and New Brunswick. In addition, industrial electricity prices in Ontario rose above those in competing states such as Ohio and Illinois, in part due to the increase in the value of the Canadian dollar. It was concluded that the price increase may lead to a greater decline in economic output in Ontario compared to competing jurisdictions. 2 tabs., 14 figs., 1 appendix

2004-01-01

Ontario's Clean Air Action Plan was launched in June 2000 in an effort to improve air quality and comply with the Canada-Wide Standards for Particulate Matter and Ozone. This paper describes Ontario's approach to reducing smog. Smog-related air pollution is linked to health problems such as premature death, respiratory and heart problems. Smog also contributes to environmental problems such as damage to forests, agricultural crops and natural vegetation. The two main ingredients of smog are ground level ozone and particulate matter. In order to reduce the incidence of smog, the following four key smog-causing pollutants must be reduced: nitrogen oxides, volatile organic compounds, sulphur dioxide and particular matter. This paper includes the 2001 estimates for Ontario's emissions inventory along with Ontario's smog reduction targets. It was noted that approximately half of all smog in Ontario comes from sources in the midwestern United States. The province of Ontario is committed to replacing coal-fired power plants with cleaner sources of energy. It is also considering emission caps for key industrial sectors. The key players in reducing smog include municipalities, industry, individuals, the federal government and programs that reduce emissions in the United States. 3 figs., 8 tabs., 1 appendix

McKenna, G.R.

1998-01-01

The implementation of a program for the naturalization of Nanticoke Park, a 30 hectare area located on the property of Ontario Hydro's Nanticoke Generating Station was discussed. The station, which is located in southern Ontario very near to noted wildlife areas, is the largest coal-fired generating station in North America. Naturalization of Nanticoke Park began with passive naturalization of interior areas. An active naturalization program involving four to five hectare size areas annually was begun in 1997, to be completed over a five -year period. This presentation described the site preparation, planting methods, post-planting tending methods, survival assessment of planted areas, and scientific research initiatives including mulch trials with zebra mussel shells to increase soil moisture. The lessons learned from the two year experiment in determining the optimum planting strategy and methods were described. 7 refs., 1 tab

Even though geothermal energy is a renewable energy source that is seen as cost-effective and environmentally friendly, emissions from geothermal plants can impact air, soil, and water in the vicinity of geothermal power plants. The Cerro Prieto geothermal complex is located 30 km southeast of the city of Mexicali in the Mexican state of Baja California. Its installed electricity generation capacity is 720 MW, being the largest geothermal complex in Mexico. The objective of this study was to evaluate whether the emissions generated by the geothermal complex have increased the soil mercury concentration in the surrounding areas. Fifty-four surface soil samples were collected from the perimeter up to an approximate distance of 7660 m from the complex. Additionally, four soil depth profiles were performed in the vicinity of the complex. Mercury concentration in 69 % of the samples was higher than the mercury concentration found at the baseline sites. The mercury concentration ranged from 0.01 to 0.26 mg/kg. Our results show that the activities of the geothermal complex have led to an accumulation of mercury in the soil of the surrounding area. More studies are needed to determine the risk to human health and the ecosystems in the study area.

Ontario electricity industry restructuring

International Nuclear Information System (INIS)

1999-01-01

The objective of Ontario's electricity industry restructuring was described as an effort to enhance Ontario's competitiveness. It is believed that restructuring can be accomplished without an increase in electricity rates. In a series of charts, the report provides the timeline of restructuring from the time of the Macdonald report in 1995 to the beginning of open competition in Ontario electricity markets. It oulines the principles underlying the financial restructuring and the financial results of restructuring, including the size of the stranded debt ($ 7.8 billion). It lists the changes that have occurred since October 1998, explains some key factors in valuing the successor companies and profiles the Ontario Electricity Financial Corporation. Restructuring of the industry is expected to have a neutral to positive impact on Ontario's fiscal position. The residual stranded debt of $7.8 billion will be retired through revenues generated by the electricity sector, without recourse to the Provincial Treasury. 9 figs

Full Text Available The level of slope influenced by the condition of the rocks beneath the surface. On high level of slopes, amount of surface runoff and water transport energy is also enlarged. This caused by greater gravity, in line with the surface tilt from the horizontal plane. In other words, topsoil eroded more and more. When the slope becomes twice as steep, then the amount of erosion per unit area be 2.0 - 2.5 times more. Kuok and surrounding area is the road access between the West Sumatra and Riau which plays an important role economies of both provinces. The purpose of this study is to map the locations that have fairly steep slopes and potential mode of landslides. Based on SRTM data obtained,  the roads in Kuok area has a minimum elevation of + 33 m and a maximum  + 217.329 m. Rugged road conditions with slope ranging from 24.08 ° to 44.68 ° causing this area having frequent landslides. The result of slope stability analysis in a slope near the Water Power Plant Koto Panjang, indicated that mode of active failure is toppling failure or rock fall and the potential zone of failure is in the center part of the slope.

Meeting Ontario's electricity needs : a critical review of the Ontario Power Authority's supply mix advice report

International Nuclear Information System (INIS)

Gibbons, J.; Fracassi, J.

2006-01-01

In December, 2005 the Ontario Power Authority (OPA) outlined its proposed blueprint for meeting Ontario's electricity needs to 2025 in the document entitled Supply Mix Advice Report. As a result of the actions taken by the current government, the OPA believes that Ontario will have adequate electricity supplies to meet the province's needs until 2013. However, it stated that Ontario will require an additional 15,000 megawatts of new generation capacity between 2013 and 2025. The OPA also recommends that a significant proportion of this new generation capacity be nuclear. The Ontario Clean Air Alliance undertook a review of the OPA report and identified several discrepancies including an over-estimation of Ontario's rate of electricity load growth from 2005 to 2025; an under-estimation of the potential for electricity productivity improvements to reduce electricity demand and raise living standards; an under-estimation of renewable energy supply potential; an under-estimation of the potential for biomass and natural gas fired combined heat and power plants to meet electricity needs and increase the competitiveness of Ontario's industries; an under-estimation of the economic costs and risks of nuclear power; and a biased recommendation for a 70 million dollar resource acquisition budget against energy efficiency investments that would reduce demand and raise living standards. This report provides the Ontario Clean Air Alliances' analysis of the OPA report and presents it own recommendations for how Ontario can increase its electricity productivity and meet its electricity supply needs until 2025. The report concluded that the Government of Ontario should direct the OPA to develop a long-term strategy to raise the price of electricity up to its full cost without raising the electricity bills of low income consumers or impairing the competitiveness of Ontario's industries. It was suggested that Ontario's electricity productivity should be increased to the same level as

Neotectonic investigations in Southern Ontario. Prince Edward County - Phase 2

McFall, G.H.; Allam, A.

1991-06-01

This report summarizes the preliminary results of geological and geophysical investigations and offshore side scan sonar surveys of the bedrock and unconsolidated sediments in Prince Edward County, Southern Ontario, by the Ontario Geological Survey in 1989. Investigations were focused on deformations in the bedrock and the surficial deposits. Some of these deformations may be neotectonic in origin. Low magnitude seismicity in the Prince Edward County region appears to be spatially related to a major regional fault system that crosses Lake Ontario and consists of the seismically active Clarendon-Linden Fault System in New York State, the Picton-Napanee and Rideau Faults, the Frontenac-Sharbot Lake Terrane Boundary and the assumed Salmon River Fault in Ontario. Detailed observations were made in the Long Point study area and the Mountain View and Picton Quarries. Bedrock structural features were documented, including: joints; normal, reverse and strike strip faults; brittle folds; and Jurassic age ultramafic dyke. Detailed refraction seismic surveys were conducted across a local fault and possible fold structures. Magnetic surveys, conducted in conjunction with the offshore side scan sonar surveys, documented large magnetic anomalies southeast of Point Petre and at the northeast end of Long Reach. Side scan sonar surveys of the lake bottom to the east of Point Petre confirm the presence of pop-ups in that area of the lake bottom which is immediately adjacent to where pop-ups are observed on land. The pop-ups present in the lake bottom have similar orientations to those mapped in the study area

An aerial radiological survey of the Ames Laboratory and surrounding area in Ames, Iowa, was conducted during the period July 15--25, 1991. The purpose of the survey was to measure and document the terrestrial radiological environment at the Ames Laboratory and the surrounding area for use in effective environmental management and emergency response planning. The aerial survey was flown at an altitude of 200 feet (61 meters) along a series of parallel lines 350 feet (107 meters) apart. The survey encompassed an area of 36 square miles (93 square kilometers) and included the city of Ames, Iowa, and the Iowa State University. The results are reported as exposure rates at 1 meter above ground level (inferred from the aerial data) in the form of a gamma radiation contour map. Typical background exposure rates were found to vary from 7 to 9 microroentgens per hour (μR/h). No anomalous radiation levels were detected at the Ames Laboratory. However, one anomalous radiation source was detected at an industrial storage yard in the city of Ames. In support of the aerial survey, ground-based exposure rate and soil sample measurements were obtained at several sites within the survey perimeter. The results of the aerial and ground-based measurements were found to agree within the expected uncertainty of ±15%

Connell, T. (Standard and Poor' s, Toronto, ON (Canada))

1999-01-01

This paper describes the methodology, including the criteria factors, comparable ratings and key credit issues used in assessing the financial positions of Ontario Power Generation Inc., and the Ontario Hydro Services Company. The rating criteria factors include both business factors (such as ownership structure, regulation, service area, operations, management, etc.,) and financial factors (e.g. financial policies and guidelines, recent financial performance, margin analysis, capital structure and borrowing plans, financial projections and sensitivities). Key credit issues include considerations of competitive dynamics, nuclear portfolio performance (for Genco), regulatory changes, cost control, capital spending program, retail business exposure, future financial performance. Comparisons are made with corresponding positions of comparable entities in Australia, Finland, New Zealand, the UK, and the USA. In the case of Ontario Power Generation Inc., the company is assessed to have significant advantages initially, but various uncertainties over the medium term warrant a more cautious view of the credit profile. For the Ontario Hydro Services Company the business risks appear to be low and moderate leverage entails a strong, stable credit profile. The overall assessment of the two companies is that while certain questions such as the workability and credibility of the new industry structure, the problem of stranded debt and questions about the liquidity of market participants remain unsolved, Ontario Power Generation Inc., and the Ontario Hydro Services Company ratings compare favorably with ratings of global industry peers.

The purpose of the survey was to measure and document the terrestrial radiological environment at the PGDP and surrounding area for use in effective environmental management and emergency response planning. The aerial survey was flown at an altitude of 61 meters (200 feet) along a series of parallel lines 107 meters (350 feet) apart. The survey encompassed an area of 62 square kilometers (24 square miles), bordered on the north by the Ohio River. The results of the aerial survey are reported as inferred exposure rates at 1 meter above ground level in the form of a gamma radiation contour map. Typical background exposure rates were found to vary from 5 to 12 microroentgens per hour (μR/h). Protactinium-234m, a radioisotope indicative of uranium-238, was detected at several facilities at the PGDR. In support of the aerial survey, ground-based exposure rate and soil sample measurements were obtained at several sites within the survey perimeter. The results of the aerial and ground-based measurements were found to agree within ±15%

The prevalence rate of congenital foolishness in investigation area is 0.64%0; while in control area, it is 0.54%0. There is no significant difference between the two areas. However, it is found that the prevalence rate of harelip in investigation area is higher than in control area, whereas the prevalence rate of congenital heart disease in control area is higher than in investigation area. As for the rests there is no significant difference. There is no significant difference between the two areas. It is concluded that nuclear tests in China did not cause hereditary disease and congenital malformation for the children who live in surrounding area, of the nuclear test site

Implications of the Ontario government's white paper and competition strategies for Ontario's municipal electric utilities

International Nuclear Information System (INIS)

Wills, D.L.

1998-01-01

The strategies that Municipal Electric Utilities (MEU) should follow to deal with competition were discussed. North Bay Hydro is the 34th largest MEU out of 300 in Ontario but it serves only 23,000 out of 4 million electrical customers in Ontario. Therefore, the main strategy for municipal utilities to ensure their future would be to become part of an alliance and association like the MEA and the SAC - the Strategic Alliance for Competition and Customer Choice. Strong criticism was voiced regarding the contents of the recent Ontario Government White Paper for being vague with regard to electrical distribution and the role of MEUs in Ontario. It was suggested that it is vitally important that MEUs ally themselves with other stakeholders, to resist an Ontario Hydro monopoly, to make sure that prices stay low, to avoid excessive debt and bureaucratic inefficiency, be innovative, and consumer oriented and be prepared to anticipate events and conditions. 3 figs

Opencast mining of large-area lignite deposits impacts the environment, and the health and life of people living in the vicinity of the conducted mining activity. Therefore, the attempt was made to develop a methodology for identification of environmental and social changes in the Bogatynia municipality (south-western Poland), resulting from functioning of Turow lignite mine within its area. During the study of changes occurring over the years, the development of mining pit was noticed, as well as the transformations of this area and impact of the mining plant on the selected elements of environment and surrounding areas. Analogue and digital data were used for the preparation of cartographic compilations, the usefulness of which was analyzed in accordance with the guidelines contained in the standard [1]. The conducted cartographic studies allowed to learn the history of the mine together with identification of changes taking place in the municipality Bogatynia. The obtained results show the form and condition of the objects in the analyzed year, allowing for the interpretation of changes that occurred in the surrounding areas of the Turow mine. Due to the conducted activity of the mine and Turow power plant, both negative and positive aspects were noted in connection with the carrying out of mining activity in the Bogatynia municipality.

McFall, G.H.; Allam, A.

1989-03-01

This report summarizes the preliminary results of geological and geophysical investigations of possible neotectonic features in Prince Edward County, southern Ontario, made by the Ontario Geological Survey during 1988. Low magnitude seismic events indicative of contemporary stress relief occurred during 1987-88 near Salmon Point and Consecon (M 2.2). These events were located proximal to a major regional fault system crossing Lake Ontario and consisting of the Clarendon-Linden Fault System in New York State and the Salmon River-Picton fault systems in Ontario. Detailed observations were made of regional jointing orientations (predominantly 60 degrees and 125 degrees), erosion of surficial deposits adjacent to open fractures, a local fault displacement (post-glacially), dome structures located at Point Petre, and dissolution/karst terrains in the eastern part of the study area. Excavations of four pop-up structures indicate that three are classical pop-ups and one is atypical in structure. Level transects were conducted across complex structures in the eastern part of the study area. Detailed refraction seismic and resistivity surveys were conducted on pop-up and fault features. Preliminary results indicate that the Picton Fault is a complex zone of fractures with differing bedrock on each side. The central zone of the East Duck Pond pop-up is fractured and may contain variable amounts of water. Overturned and upright folds in the Consecon Quarry located outside of the primary research area were documented and found to be trending in a west-northwest to northwest direction. This fold orientation is compatible both with a glacial shove origin and with the present stress field orientations. Although glacial shove can produce overturned folds, it cannot form upright folds. A regional, tectonic deformation oriented northeasterly is therefore suggested as the causative mechanism

Surface sediments and sediment cores collected at the Pearl River Estuary (PRE) and its surrounding coastal area were analysed for total metal concentrations, chemical partitioning, and Pb isotopic compositions. The distribution of Cu, Cr, Pb, and Zn demonstrated a typical diffusion pattern from the land to the direction of the sea. Two hotspots of trace metal contamination were located at the mixed zone between freshwater and marine waters. The enrichment of metals in the sediments could be attributed to the deposition of the dissolved and particulate trace metals in the water column at the estuarine area. The similar Pb isotopic signatures of the sediments at the PRE and its surrounding coastal area offered strong evidence that the PRE was a major source of trace metals to the adjacent coastal area. Slightly lower 206 Pb/ 207 Pb ratios in the coastal sediments may indicate other inputs of Pb in addition to the PRE sources, including the inputs from Hong Kong and other parts of the region. - The distribution of trace metals in sediments reflected contaminant sources, physical and chemical deposition processes

An airborne radiological survey of an 1100 km 2 area surrounding the St. Lucie Power Plant was conducted 1 to 8 March 1977. Detected radioisotopes and their associated gamma ray exposure rates were consistent with that expected from the normal background emitters. Count rates observed at 150 m altitude are converted to equivalent exposure rates at 1 m above the ground and are presented in the form of an isopleth map. Ground exposure rates measured with small portable instruments and soil sample analysis agreed with the airborne data. Geological data are presented in an isopleth map of rock and soil types. Also included is a brief description of the vegetation and terrain surrounding the site

Ontario perspective on interregional markets

International Nuclear Information System (INIS)

Shalaby, A.

2003-01-01

On May 1, 2002, wholesale and retail electricity markets in Ontario were opened to competition. The industry structure has been completely unbundled into separate entities for power generation, distribution and transmission. There are currently 20 generators, 90 distributors and 4 transmitters in Ontario. Trade with neighbouring jurisdictions has increased and now accounts for 10 to 15 per cent of demand on summer peak days. Import/export capability with the United States (northeast and midwest) and other Canadian provinces (Quebec and Manitoba) is 4,000 to 6,000 MW. Ontario has not had new generation or transmission capacity in several years and the heat waves of summer 2002 resulted in a heavier power demand than forecasted. The province had to rely heavily on power imports resulting in high and volatile electricity prices. In response to customer complaints, the Ontario government froze retail rates and in a recent policy directive announced a public ownership policy for transmission with further consultation on improving supply competition in Ontario. FERC order 888 and the increased role of independent power producers has improved trading opportunities between Canada and the United States. The presentation highlighted recent trade trends and outlined the specific impact of the Standard Market Design on Canadian markets. It was noted that Ontario should work on ensuring power reliability, transmission planning, inter-regional coordination, and joint investments with neighbouring jurisdictions. 9 figs

Robertson, J.A.

1981-01-01

The principal types of uranium deposits in Ontario are carbonatites and fenites, alkalic volcanic rocks, pegiatites, calc-silicate rocks, pyritic quartz-pebble conglomerates, polymictic conglomerates and some pelitic rocks, and various 'pitchblende' deposits including late Precambrian unconformities, possibly late Precambrian diabase dikes, and other unconformities: carbonates, sandstones, lignites, and semi-pelitic rocks of middle and upper Precambrian age. Only red unzoned pegmatite and the pyritic quartz-pebble conglomerate have supported production. Ontario reasonably assured and estimated resources in the economic and subeconomic categories in 1977 amounted to 553 000 tonnes U, and 1977 production was 4000 tonnes U. Measured, indicated, and inferred resources in the Elliot Lake - Agnew Lake area are at least 400 000 tonnes U. The latter deposits are also a significant thorium resource. Geological features reflecting major changes in physics and chemistry are prime controls on distribution of uranium deposits. Geological province and subprovince boundaries, major faults, higher metamorphic grades, domain boundaries related to quartz monzonite batholiths, alkalic complexes, and the distribution of carbonate rocks are examples of such geological features

Recent feed-in-tariff (FIT) programs in Ontario, Canada have elicited a very strong supply response. Within the first year of their inception, the Ontario Power Authority received applications totaling over 15,000 MW, equivalent to about 43% of current Ontario electricity generating capacity. The overwhelming share of applications is for wind-power (69%) and solar photovoltaic (28%) generating facilities. Wind generation is being remunerated at 14-19 cents /kWh. Solar facilities receive from 40 to 80 cents /kWh. The initiative, which responds to Provincial legislation is administratively divided into applications for facilities exceeding 10 kW (the FIT program) and those less than or equal to 10 kW (the microFIT program). This paper describes the programs and their features, compares them to their predecessors in Ontario as well as to programs elsewhere, analyses the reasons for the very strong response, and assesses their efficacy and sustainability. - Research highlights: → Recent feed-in-tariff (FIT) programs in Ontario, Canada have elicited a very strong supply response. Within the first year, applications totaled over 15,000 MW, equivalent to about 43% of current Ontario electricity generating capacity. → Most projects are either solar or wind. → Likely causes of strong supply response-preferred system access and favorable, secure tariffs. (Wind generation is being remunerated at 14-19 cents /kWh. Solar facilities receive from 40 to 80 cents /kWh.) → Long term political sustainability of present program is in question.

1994-11-01

A team from the Remote Sensing Laboratory in Las Vegas, Nevada, conducted an aerial radiation survey of the area surrounding ground zero of Project Rio Blanco in the northwestern section of Colorado in June 1993. The object of the survey was to determine if there were man-made radioisotopes on or near the surface resulting from a nuclear explosion in 1972. No indications of surface contamination were found. A search for the cesium-137 radioisotope was negative. The Minimum Detectable Activity for cesium-137 is presented for several detection probabilities. The natural terrestrial exposure rates in units of Roentgens per hour were mapped and are presented in the form of a contour map over-laid on an aerial photograph. A second team made independent ground-based measurements in four places within the survey area. The average agreement of the ground-based with aerial measurements was six percent

Challenges of rehabilitation case mix measurement in Ontario hospitals.

Sutherland, Jason Murray; Walker, Jan

2008-03-01

Case mix classification systems have been adopted in many countries as a method to manage and finance healthcare in acute care settings; the most popular systems are based on diagnosis related groups. The most successful of those case mix systems differentiate patient types by reflecting both the intensity of resources consumed and patient acuity. Case mix systems for use with non-acute hospital activity have not been as wide-spread; other than in the United States, little attention has been directed towards case mix classification for rehabilitation activity. In a province with over 13 million inhabitants with 2496 rehabilitation beds, inpatient rehabilitation is an important component of hospital care in Ontario, Canada, and consists of the spectrum of intensive rehabilitation activities intended to restore function. Although case mix adjusted activity has been the currency in Ontario's Integrated Population Based Allocation hospital funding formula, rehabilitation activity has not been subjected to case mix measurement. A project to examine case mix classification for adult inpatient rehabilitation activity was initiated by the Ontario Ministry of Health and Long-Term Care whose outcome was a case mix system and associated cost weights that would result in rehabilitation activity being incorporated into the hospital funding formula. The process described in this study provides Ontario's provincial government with a case mix classification system for adult inpatient rehabilitation activity although there remain areas for improvement.

Screening for cervical, breast and colon cancers, and elevations of cholesterol and glucose, reduces premature cause-specific mortality from these cancers and circulatory diseases. Despite primary care reforms and incentives, and promotion of cancer-screening programs among individuals, participation is suboptimal. We aimed to examine participation as of Dec. 31, 2011, by factors of deprivation, demographics and primary care at the small-area level. From health care administrative databases, we identified people eligible for each screening test, and their participation, in each dissemination area (referred to as small areas, n = 18 950) in Ontario. We calculated rates for each test among small areas (overall and stratified by demographic, socioeconomic and primary care descriptors) and stratified by sex for all tests combined. We loaded all data into a geographic information system. Funnel plots were generated showing the percentage of eligible people who completed screening for all tests by small area, stratified by sex. Overall and stratified screening prevalence ratios were calculated among small areas. Among small areas, the mean and SD for participation in all tests combined was 31.6% (SD 11.0%) for women and 41.2% (SD 12.0%) for men. Screening prevalence among small areas, for each test and for all tests combined, overall and stratified by sex, declined with decreasing percentage with high school completion, decreasing socioeconomic quintile, and decreasing percentage with an identifiable primary care physician. Our results show that the rate of participation in all eligible screening tests among small areas is much lower than the rate of participation in any one particular test. This finding has implications for the design and implementation of strategies to improve rates of screening.

Gipe, P.

2007-11-01

The Ontario Sustainable Energy Association (OSEA) promotes the development of community-owned renewable energy generation. It was emphasized that in order to achieve OSEA's original objectives of developing as much renewable energy as quickly as possible through community participation, changes are needed to Ontario's groundbreaking standard offer contract (SOC) program. This report examined the status of Ontario's SOC program and proposed changes to the program as part of the program's first two-year review. The report provided a summary of the program and discussed each of the program's goals, notably to encourage broad participation; eliminate barriers to distributed renewable generation; provide a stable market for renewable generation; stimulate new investment in renewable generation; provide a rigorous pricing model for setting the tariffs; create a program applicable to all renewable technologies; provide a simple, streamlined, and cost-effective application process; and provide a dispute resolution process. The program goals as developed by the Ontario Power Authority and Ontario Energy Board were discussed with reference to mixed results to date; simplicity; removing barriers; balancing targets with value to ratepayers; and building on the efforts of OSEA. Advanced renewable tariffs (ART) and tariff determination was also discussed along with ART's in Germany, France, Spain and Ontario. Inflation indexing; tariff degression; proposed new tariffs by technology; and other costs and factors affecting profitability were also reviewed. ref., tabs

Tobacco Retail Outlets and Vulnerable Populations in Ontario, Canada

2013-12-01

Full Text Available Interest has been increasing in regulating the location and number of tobacco vendors as part of a comprehensive tobacco control program. The objective of this paper is to examine the distribution of tobacco outlets in a large jurisdiction, to assess: (1 whether tobacco outlets are more likely to be located in vulnerable areas; and (2 what proportion of tobacco outlets are located close to schools. Retail locations across the Province of Ontario from Ministry of Health Promotion data were linked to 2006 Census data at the neighbourhood level. There was one tobacco retail outlet for every 1,000 people over age 15 in Ontario. Density of outlets varied by public health unit, and was associated with the number of smokers. Tobacco outlets were more likely to be located in areas that had high neighbourhood deprivation, in both rural and urban areas. Outlets were less likely to be located in areas with high immigrant populations in urban areas, with the reverse being true for rural areas. Overall, 65% of tobacco retailers were located within 500 m of a school. The sale of tobacco products is ubiquitous, however, neighbourhoods with lower socio-economic status are more likely to have easier availability of tobacco products and most retailers are located within walking distance of a school. The results suggest the importance of policies to regulate the location of tobacco retail outlets.

The rates of total joint arthroplasty (TJA) of the hip and knee have increased in North America over the last decade. While initially designed for elderly patients (>70 years of age), several reports suggest that an increasing number of younger patients are undergoing joint replacements. This suggests that more people are meeting the indication for TJA earlier in their lives. Alternatively, it might indicate a broadening of the indications for TJA. We used the administrative databases available at the Healthcare Cost and Utilization Project (HCUP) and the Institute for Clinical Evaluative Sciences (ICES) to determine the rates of TJA of the hip and knee in the United States, and Ontario, Canada, respectively. We determined the crude rates of THA and TKA in both areas for four calendar years (2001, 2003, 2005 and 2007). We also calculated the age- and sex-standardised rates of THA and TKA in both areas for each time period. We compared the age distribution of TJA recipients between the US and Ontario, and within each area over time. The crude and standardised rates of THA and TKA increased over time in both the US and Ontario. The crude rates of THA were higher in the US in 2001 and 2003, but were not significantly different from the rate in Ontario in 2005 and 2007. The crude rates of TKA were consistently higher in the US for all time periods. In addition, the US consistently had more THA and TKA recipients in 'younger' age categories (age). While the age- and sex-standardised rates of TKA were greater in the US in all time periods, the relative increase in rates from 2001 to 2007 was greater in Ontario (US - 59%, Ontario - 73%). For both the US and Ontario, there was a significant shift in the demographic of THA and TKA recipients to younger patients (p age groups in the general population, in both the US and Ontario.

Full Text Available Based on agro-climate factors, most of surrounding area of coal mining sites in Indonesia is suitable for cocoa cultivation. However, most of cocoa farmers in the environs of coal mining sites have little access both to new technology of cocoa cultivation and to market of their cocoa products. Therefore, productivity of cocoa farms and the income of cocoa farmers are low, which may disturb social responsibility of the coal mining companies present in their surroundings. These are the consequences of poor interaction between the government, private sector and research sector. The aim of this study is to transfer and to implement good agricultural practices of cocoa in surrounding area of mining sites of Kaltim Prima Coal (KPC and Berau Coal (BC, East Kalimantan, in order to increase farmer capacity and cocoa productivity.

Biogeography of azooxanthellate corals in the Caribbean and surrounding areas

Science.gov (United States)

Dawson, J.

2002-04-01

Biogeographic patterns for azooxanthellate corals are not as well known as those of zooxanthellate (primarily reef-building) corals. I analyzed occurrences of 129 species of azooxanthellate corals in 19 geopolitical regions in the Caribbean and surrounding areas. I performed an unweighted pair-group method with arithmetic averages (UPGMA) cluster analysis using Bray-Curtis' similarity measure on the complete data set and shallow- and deep-water subsets of the data. The results indicate two provinces, each with a widespread (tropical and subtropical distributions) component to its fauna. One province has a tropical and primarily insular component to it, while the other has a subtropical and primarily continental component. By contrast, zooxanthellate corals have a uniform faunal composition throughout the Caribbean. Moreover, zooxanthellate corals have half as many species in the Caribbean as the azooxanthellate corals even though their global diversities are equal. These differences in diversity and geographic distribution patterns should be considered when developing conservation strategies.

1993-12-01

An aerial radiological survey was conducted during the period of October 14 to November 23, 1991, over an area surrounding the United States Department of Energy's Savannah River Site (SRS). The area is situated 15 kilometers south of Aiken, South Carolina. The purpose of the survey was to measure and document the gamma ray environment of the SRS and surrounding areas. Contour maps showing gamma radiation exposure rates at 1 meter above ground level were constructed from the aerial data and overlaid on a United States Geological Survey map of the area. The exposure rates measured within the survey region are generally uniform and typical of natural background. The reported exposure rate values include an estimated cosmic ray contribution. Enhanced exposure rates not attributable to natural background were measured over several areas within the survey region. The manmade radionuclides detected in these areas, cesium-137, cobalt-60, and protactinium-234m, were produced by the reactor operations and material processing conducted at the SRS. The radiation levels produced by these nuclides are consistent with those levels measured during previous SRS aerial surveys. Radionuclide assays of soil samples and pressurized ion chamber measurements were obtained at four locations within the survey boundaries

Assessing Local and Surrounding Threats to the Protected Area Network in a Biodiversity Hotspot: The Hengduan Mountains of Southwest China.

Protected areas (PAs) not only serve as refuges of biodiversity conservation but are also part of large ecosystems and are vulnerable to change caused by human activity from surrounding lands, especially in biodiversity hotspots. Assessing threats to PAs and surrounding areas is therefore a critical step in effective conservation planning. We apply a threat framework as a means of quantitatively assessing local and surrounding threats to different types of PAs with gradient buffers, and to main ecoregions in the Hengduan Mountain Hotspot of southwest China. Our findings show that national protected areas (NPAs) have lower and significantly lower threat values (pprotected areas (PPAs) and other protected areas (OPAs), respectively, which indicates that NPAs are lands with a lower threat level and higher levels of protection and management. PAs have clear edge effects, as the proportion of areas with low threat levels decline dramatically in the 5-kilometer buffers just outside the PAs. However, NPAs suffered greater declines (58.3%) than PPAs (34.8%) and OPAs (33.4%) in the 5-kilometer buffers. Moreover, a significant positive correlation was found between the size of PAs and the proportion of areas with low threat levels that they contained in both PAs and PA buffers (p<0.01). To control or mitigate current threats at the regional scale, PA managers often require quantitative information related to threat intensities and spatial distribution. The threat assessment in the Hengduan Mountain Hotspot will be useful to policy makers and managers in their efforts to establish effective plans and target-oriented management strategies.

2002-01-01

The recent measures taken by Ontario Power Generation since 1998 to deregulate the electricity market in the province of Ontario are reviewed. The opening of Ontario's power market in May 2002 will oblige Ontario Power Generation to reduce its market share. The author reviewed the current status of the energy market in Ontario and noted a modest growth in demand. A significant portion of the energy supply is being provided by nuclear, fossil fuels and hydro energy. The challenge facing Ontario Power Generation is to stay competitive in the new deregulated market and to participate in the energy market in the United States. 6 figs

Weidel, Brian C.; Walsh, Maureen; Holden, Jeremy P.; Connerton, Michael J.

2016-01-01

Benthic prey fishes are a critical component of the Lake Ontario food web, serving as energy vectors from benthic invertebrates to native and introduced piscivores. Since the late 1970’s, Lake Ontario benthic prey fish status was primarily assessed using bottom trawl observations confined to the lake’s south shore, in waters from 8 – 150 m (26 – 492 ft). In 2015, the Benthic Prey Fish Survey was cooperatively adjusted and expanded to address resource management information needs including lake-wide benthic prey fish population dynamics. Effort increased from 55 bottom trawl sites to 135 trawl sites collected in depths from 8 - 225m (26 – 738 ft). The spatial coverage of sampling was also expanded and occurred in all major lake basins. The resulting distribution of tow depths more closely matched the available lake depth distribution. The additional effort illustrated how previous surveys were underestimating lake-wide Deepwater Sculpin, Myoxocephalus thompsonii, abundance by not sampling in areas of highest density. We also found species richness was greater in the new sampling sites relative to the historic sites with 11 new fish species caught in the new sites including juvenile Round Whitefish, Prosopium cylindraceum, and Mottled sculpin, Cottus bairdii. Species-specific assessments found Slimy Sculpin, Cottus cognatus abundance increased slightly in 2015 relative to 2014, while Deepwater Sculpin and Round Goby, Neogobius melanostomus, dramatically increased in 2015, relative to 2014. The cooperative, lake-wide Benthic Prey Fish Survey expanded our understanding of benthic fish population dynamics and habitat use in Lake Ontario. This survey’s data and interpretations influence international resource management decision making, such as informing the Deepwater Sculpin conservation status and assessing the balance between sport fish consumption and prey fish populations. Additionally a significant Lake Ontario event occurred in May 2015 when a single

Beware: The empire striking back: An update of regulatory changes in Ontario`s gas and electricity business as at February 1998

Rosenberg, K. [Gowling, Strathy and Henderson, Toronto, ON (Canada)

1998-09-01

A review of what is happening with regard to deregulation of the gas and electricity industry in Ontario was presented. Recently, a series of government actions in Ontario have recommended fundamental changes in the gas and electric power sector. Prior to the October 31, 1985 agreement, no competitive market existed within local distribution franchises in Ontario or elsewhere in Canada. The Agreement created gas on gas competition and enabled consumers to purchase natural gas from producers at negotiated prices. The Ontario government`s proposed legislation and implementation schedule forecasts even more fundamental changes for the province`s electric power industry. Essentially, the legislation proposes to break up Ontario Hydro into several different entities and transfer regulatory authority to the Ontario Energy Board. The pending legislation also envisages the structural separation of local distribution companies into natural monopolies which will compete in the marketplace. The possibility of privatizing part or all of Ontario`s nuclear assets is also part of the ongoing debate. It was the author`s view that unless there is immediate and complete structural separation of all monopoly services within the gas and electric utilities, the market will not be truly competitive. Instead, regulated monopoly pricing would be replaced by unregulated oligopoly pricing. 1 tab.

Sensitivity of GRACE-derived estimates of groundwater-level changes in southern Ontario, Canada

Hachborn, Ellen; Berg, Aaron; Levison, Jana; Ambadan, Jaison Thomas

2017-12-01

Amidst changing climates, understanding the world's water resources is of increasing importance. In Ontario, Canada, low water conditions are currently assessed using only precipitation and watershed-based stream gauges by the Conservation Authorities in Ontario and the Ministry of Natural Resources and Forestry. Regional groundwater-storage changes in Ontario are not currently measured using satellite data by research institutes. In this study, contributions from the Gravity Recovery and Climate Experiment (GRACE) data are compared to a hydrogeological database covering southern Ontario from 2003 to 2013, to determine the suitability of GRACE total water storage estimates for monitoring groundwater storage in this location. Terrestrial water storage data from GRACE were used to determine monthly groundwater storage (GWS) anomaly values. GWS values were also determined by multiplying groundwater-level elevations (from the Provincial Groundwater Monitoring Network wells) by specific yield. Comparisons of GRACE-derived GWS to well-based GWS data determined that GRACE is sufficiently sensitive to obtain a meaningful signal in southern Ontario. Results show that GWS values produced by GRACE are useful for identifying regional changes in groundwater storage in areas with limited available hydrogeological characterization data. Results also indicate that GRACE may have an ability to forecast changes in groundwater storage, which will become useful when monitoring climate shifts in the near future.

The recent introduction of both the AECB Transport Packaging of Radioactive Material Regulations and Transport Canada's Transportation of Dangerous Goods Regulations have significantly altered the requirements for transporting radioactive material in Canada. Extensive additional training as well as certification of several hundred Ontario Hydro employees has been necessary to ensure compliance with the additional and revised regulatory requirements. To assist in the training of personnel, an 'active' corporate Ontario Hydro Field Guide for Radioactive Material Transport document has been developed and published. The contents of this Field Guide identify current Ontario Hydro equipment and procedures as well as the updated relevant regulatory requirements within Canada. In addition, to satisfying Ontario Hydro requirements for this type of information over two thousand of these Field Guides have been provided to key emergency response personnel throughout the province of Ontario to assist in their transportation accident response training

Retailers test Ontario market

In anticipation of the full opening of the Ontario electricity market in November 2000, some of the newly-licensed electricity retailers are reported to be ready to begin testing the market early, hoping that all the uncertainties that still exist about pricing will be worked out in time. Among those jumping in now is Direct Energy Marketing, a retailer which claims 800,000 households in Ontario as electricity supply customers, as well as a wholesale gas marketing business. Direct Energy began retail electrical marketing on April 3, 2000, starting cautiously with small commercial operations as the initial target. Greengrid Electric, another of the new marketers, planned to begin marketing in mid-April, offering 100 per cent renewable-sourced electricity. Provident Energy Management, one of the new marketers whose licence is still pending, hopes to begin direct marketing as soon as its licence is confirmed. Another marketer ready to go as soon its license is issued is the former Sault Ste. Marie Hydro, now reorganized as PUC Energies Inc. PUC has the advantage of having a firm contract with a NUG (non-utility generator), Great Lakes Power, signed while PUC was still a municipal electric utility. As far as the other potential marketers are concerned, caution overrides opportunity for the present. Principal concerns are uncertainty over the retail settlement code, the electronic business data transfer system, transmission and distribution tariffs, whether existing non-utility generator contracts will allow for supply to another party, and over how quickly Ontario Power Generation Inc's (successor to Ontario Hydro) market power will be ratcheted down. Many of the potential marketers feel that despite the Ontario government's desire to see more competition, the power mitigation agreement, as it now reads, leaves little room for the small retailer to compete.

Brett, J.T.

1997-01-01

The current status of the natural gas industry and the electric power industry in Ontario, in terms of deregulation, was described. Natural gas utilities will exit the regulated gas market over the next few years and transfer their existing residential and small commercial gas contracts to their unregulated affiliates. Nevertheless, a regulated gas supply option will remain until the regulator is assured that consumer protection issues have been properly addressed, and there is a truly competitive market. Ontario Hydro is a vertically integrated virtual monopoly. It lags behind B.C., Alberta, Quebec and Nova Scotia in terms of deregulation and restructuring, although the MacDonald Commission's recent report recommended sweeping changes to Ontario Hydro's monopoly over the electric power industry. A final response from the Ontario government is still pending. The convergence of the electric power and natural gas industries was also discussed

Air pollutant emissions from U.S. sources account for a large percentage of Ontario's air quality problems. Accordingly, Ontario supported the U.S. Environmental Protection Agency in March 2001, when the U.S. Supreme Court decided in favour of the EPA in its effort to require significant reductions in emissions of smog-causing substances by many states. Details of these achievements, and an indication of future directions in the fight to improve air quality in the province are provided.

Ontario's energy action plan

International Nuclear Information System (INIS)

2003-07-01

In the fall of 2002, the government of Ontario announced an action plan designed to ensure stable electricity prices while additional electricity generating capacity is built. The action plan included a strategy for encouraging major private sector investments in wind, solar and other renewable energy sources. The strategies for new renewable energy projects include: property tax incentives, business income tax incentives, and sales tax rebates. Initiatives to increase supply include: Toronto's Portland 550 megawatt, natural gas-fired generating station, Niagara Falls' Beck Tunnel Project, and Windsor's 580 megawatt natural gas-fired generating station. The government is promoting energy conservation by reducing its electricity consumption by 10 per cent, and setting a target where 20 per cent of electricity consumed in the province must be from renewable energy sources. The use of interval meters by Ontario residents is being encouraged. A provincial sales tax rebate is being offered to customers buying select energy efficient appliances. In its commitment to environmental protection, the Ontario government is phasing out coal, offering rebates for solar energy systems, implementing measures to reduce acid rain, and investing $3.25 billion over ten years to renew and expand public transit. In Chatham, Ontario, a plant producing ethanol from corn was built, and others are planned for other parts of the province. Tax incentives are also offered for alternative fuel users. 1 ref., 1 tab

The history of acupuncture in Ontario, Canada was traced, and the current status as welI as the prospection were introduced in this paper. Statistics showed that the history of acupuncture in Ontario started in the 1880s, and it was only popular in China Town and Chinese community. In the 1970s, it gradually merged into the mainstream of the society, and entered into a growing period. With the tide of Chinese immigration in the 1980s and 1990s, acupuncture matured rapidly. In 2006, the "Traditional Chinese Medicine Act" was passed in Ontario, it was considered as a milestone in the history of acupuncture. At present, just like the other 23 health care professions, acupuncture has already be included into the legislation system, and become a component of Ontario's health care system. At the same time, the law and regulation may also promote the establishment of "pure Chinese Medicine" in Ontario.

Market prices for solar electricity in Ontario

Rowlands, I.H.

2006-01-01

The Ontario electricity supply is facing considerable challenges while demand is increasing due to a growing population and increased economic growth needs. In response to these challenges, the government of Ontario established the Ontario Power Authority (OPA) in 2004 to ensure adequate, reliable and secure electricity supply and resources in Ontario. The OPA has also engaged in activities to facilitate the diversification of sources of electricity supply by promoting the use of cleaner energy sources and technologies, including alternative energy sources and renewable energy. The purpose of this paper was to advance discussions regarding the contribution that solar PV can make to Ontario's supply mix. In particular, it determined the value of the electricity that would have been produced by a PV system located in Waterloo, Ontario under the following 4 pricing regimes: (1) the conventional small user tariff system currently in place in Ontario, (2) the time-of-use pricing system that is voluntarily available to those who have smart meters installed in their facilities, (3) the spot market, hourly prices, to which some of Ontario's largest electricity users are exposed, and (4) the recently-proposed rate for standard offer contracts for PV systems. The study showed that a solar PV system that produces 3,000 kWh of electricity over the course of a year would generate different revenue amounts, ranging from the smallest amount of approximately $174.00 to $1,260.00, depending on the pricing regime. The pricing regime that reflects real, time-of-day electricity prices appears to be most advantageous to solar PV systems. It was recommended that additional work is needed regarding the other benefits of solar PV, such as avoided capacity/generation needs, avoided transmission and distribution cost and losses, environmental benefits, and job creation. 3 refs., 4 tabs., 8 figs

An aerial radiological survey of the Sandia National Laboratories and surrounding area

1994-06-01

A team from the Remote Sensing Laboratory conducted an aerial radiological survey of the area surrounding the Sandia National Laboratories and Kirtland Air Force Base in Albuquerque, New Mexico, during March and April 1993. The survey team measured the terrestrial gamma radiation at the site to determine the levels of natural and man-made radiation. This survey includes the areas covered by a previous survey in 1981. The results of the aerial survey show a background exposure rate which varies between 5 and 18 μR/h plus an approximate 6 μR/h contribution from cosmic rays. The major radioactive isotopes found in this survey were: potassium-40, thallium-208, bismuth-214, and actinium-228, which are all naturally-occurring isotopes, and cobalt-60, cesium-137, and excess amounts of thallium-208 and actinium-228, which are due to human actions in the survey area. In regions away from man-made activity, the exposure rates inferred from this survey's gamma ray measurements agree almost exactly with the exposure rates inferred from the 1981 survey. In addition to the aerial measurements, another survey team conducted in situ and soil sample radiation measurements at three sites within the survey perimeter. These ground-based measurements agree with the aerial measurements within ± 5%

The restructuring of the Ontario electricity market

Doucet, J.A.

1999-01-01

A summary of the current status of the deregulation of the electricity market in Ontario was presented. To follow global deregulation trends, the Ontario Government has embarked on a considerable restructuring of the Ontario electricity market. The monopoly position of Ontario Hydro has been removed by restructuring the provincial utility into two separate companies, GENCO and SERVCO, which will be responsible for the generation and transmission and distribution of electricity, respectively. Other mechanisms put in place to favour a free and competitive market for electricity in the province, such as the arrival on the market of other electricity producers, and the establishment of the independent market operator, are also discussed. 2 tabs

Accreditation in Ontario, Canada, requires that licensed clinical laboratories participate in external quality assessment (also known as proficiency testing) and perform competency evaluation of their staff. To assess the extent of ongoing competency assessment practices, the Quality Management Program--Laboratory Services (QMP-LS) Microbiology Committee surveyed all 112 licensed Ontario microbiology laboratories. The questionnaire consisted of a total of 21 questions that included yes/no, multiple-choice, and short-answer formats. Participants were asked to provide information about existing programs, the frequency of testing, what areas are evaluated, and how results are communicated to the staff. Of the 111 responding laboratories, 6 indicated they did not have a formal evaluation program since they perform only limited bacteriology testing. Of the remaining 105 respondents, 87% perform evaluations at least annually or every 2 years, and 61% include any test or task performed, whereas 16% and 10% focus only on problem areas and high-volume complex tasks, respectively. The most common methods of evaluation were review of external quality assessment (EQA) challenges, direct observation, and worksheet review. With the exception of one participant, all communicate results to staff, and most take remedial action to correct the deficiencies. Although most accredited laboratories have a program to assess the ongoing competency of their staff, the methods used are not standardized or consistently applied, indicating that there is room for improvement. The survey successfully highlighted potential areas for improvement and allowed the QMP-LS Microbiology Committee to provide guidance to Ontario laboratories for establishing or improving existing microbiology-specific competency assessment programs.

Cooperatives and the State: The Case of Ontario

Directory of Open Access Journals (Sweden)

Rachel Laforest

2011-01-01

Full Text Available In the early 2000s, the cooperative movement in Ontario came together in order to lobby its provincial government for active cooperative development support programs. Momentum was building for these types of programs. Already, many provincial governments had implemented active support programs in their jurisdiction. Despite having one of the largest cooperative sectors in Canada, Ontario was lagging behind. This article assesses the progress of the efforts of the Ontario cooperative movement to date. It details how the Ontario cooperative movement developed a sectoral identity for itself and framed its objectives in an effort to strengthen its relationship with the Ontario government. / Le mouvement coopératif en Ontario s'est rassemblé au début des années 2000 afin de faire pression sur le gouvernement provincial pour qu'il développe des programmes de soutient actif pour coopératives. Déjà plusieurs gouvernements provinciaux avaient mis en place de telles politiques. L'Ontario tardait malgré le fait qu'il avait un des plus grands secteurs coopératifs au Canada. Cet article examine le progrès qu'a connu le mouvement coopératif en Ontario dans ses efforts. Il décrit comment le mouvement coopératif a construit une identité sectorielle autour de laquelle il a pu ancrer ses demandes auprès du gouvernement ontarien.

Expanding exports, increasing smog : Ontario Power Generation's and Hydro One's strategies to continue coal-fired electricity generation in Ontario

International Nuclear Information System (INIS)

Gibbons, J.

2002-06-01

The production of coal-fired electricity increased by approximately 150 per cent in Ontario between 1995 and 2000. As a result, the smog-causing emissions generated by the five coal-fired power plants operated by Ontario Power Generation caused an increase in smog and worsened air quality in the province as well as affecting air quality as far afield as the Atlantic provinces. Between 2002 and 2005, it is expected that the Pickering and Bruce nuclear plants will be returned to service, making the electricity generated by the coal plants surplus to Ontario's needs. Increasing this surplus are the planned natural gas generating stations. Ontario Power Generation is planning on using this surplus to export it to the United States rather than phasing out its reliance on coal. The increase in exports to the United States Northeast and Midwest is planned with Hydro One, already busy increasing its transmission capacity to the United States by 1,000 megawatt (MW). This plan involves laying 975 MW submarine cable from the Nanticoke Generating Station (operated by Ontario Power Generation) under Lake Erie to Pennsylvania, Ohio, or both states. At the moment, the exports are constrained by the government emissions limits imposed by the Ontario government on sulphur dioxide and nitrogen oxides. This constraint could be removed if Ontario Power Generation decides to pay further for pollution controls for sulphur dioxide and nitrogen oxides at its coal stations. Unfortunately, increasing the exports would also result in emissions increases for 28 other uncapped pollutants such as lead, mercury and arsenic. The author recommended that the Ontario government ban non-emergency coal-fired electricity exports to improve air quality in the province. refs., 8 figs

Scale and watershed features determine lake chemistry patterns across physiographic regions in the far north of Ontario, Canada

Josef MacLeod

2016-11-01

Full Text Available Changes in the far north of Ontario (>50°N latitude, like climate warming and increased industrial development, will have direct effects on watershed characteristics and lakes. To better understand the nature of remote northern lakes that span the Canadian Shield and Hudson Bay Lowlands, and to address the pressing need for limnological data for this vast, little-studied area of Ontario, lake chemistry surveys were conducted during 2011-2012. Lakes at the transition between these physiographic regions displayed highly variable water chemistry, reflecting the peatland landscape with a mix of bog and fen watersheds, and variations in the extent of permafrost. In the transition area, Shield and Lowlands lakes could not be clearly differentiated based on water chemistry; peat cover decouples, to varying degrees, the lakes from the influences of bedrock and surficial deposits. Regional chemistry differences were apparent across a much broader area of northern Ontario, due to large-scale spatial changes in geology and in the extent of peatlands and permafrost.  Shield lakes in the far northwest of Ontario had Ca, Mg, and TP concentrations markedly higher than those of many Lowlands lakes and previously studied Shield lakes south of 50°N, related to an abundance of lacustrine and glacial end-moraine deposits in the north.

Many stakeholders are seeking methods to reduce carbon dioxide (CO2) emissions in urban areas, but reliable, high-resolution inventories are required to guide these efforts. We present the development of a high-resolution CO2 inventory available for the Greater Toronto Area and surrounding region in Southern Ontario, Canada (area of ˜ 2.8 × 105 km2, 26 % of the province of Ontario). The new SOCE (Southern Ontario CO2 Emissions) inventory is available at the 2.5 × 2.5 km spatial and hourly temporal resolution and characterizes emissions from seven sectors: area, residential natural-gas combustion, commercial natural-gas combustion, point, marine, on-road, and off-road. To assess the accuracy of the SOCE inventory, we developed an observation-model framework using the GEM-MACH chemistry-transport model run on a high-resolution grid with 2.5 km grid spacing coupled to the Fossil Fuel Data Assimilation System (FFDAS) v2 inventories for anthropogenic CO2 emissions and the European Centre for Medium-Range Weather Forecasts (ECMWF) land carbon model C-TESSEL for biogenic fluxes. A run using FFDAS for the Southern Ontario region was compared to a run in which its emissions were replaced by the SOCE inventory. Simulated CO2 mixing ratios were compared against in situ measurements made at four sites in Southern Ontario - Downsview, Hanlan's Point, Egbert and Turkey Point - in 3 winter months, January-March 2016. Model simulations had better agreement with measurements when using the SOCE inventory emissions versus other inventories, quantified using a variety of statistics such as correlation coefficient, root-mean-square error, and mean bias. Furthermore, when run with the SOCE inventory, the model had improved ability to capture the typical diurnal pattern of CO2 mixing ratios, particularly at the Downsview, Hanlan's Point, and Egbert sites. In addition to improved model-measurement agreement, the SOCE inventory offers a sectoral breakdown of emissions

Ontario Hydro, North America's largest electric power utility, with an installed capacity of 34,000 MW, has under gone a major restructuring over the past year to better align itself with a changing electricity market and evolving customer needs. The single largest new business unit within the new Ontario Hydro is Ontario Hydro Nuclear (OHN), responsible for engineering, operation and maintenance of the Corporation's 20 large nuclear units at three generating sites, OHN faces a significant challenge in returning Ontario's nuclear units to the world-leading performance levels they enjoyed in the past, particularly the older Pickering A and Bruce A plants. However, steady progress is being made as evidenced by improving peer reviews and overall capacity and financial performance

Barriers to offering French language physician services in rural and northern Ontario.

2016-01-01

Rural and Northern Ontario francophones face many health-related challenges including poor health status, a poor supply of French-speaking physicians, and the potential for an inability or reduced ability to effectively communicate with anglophone healthcare providers. As such, it can reasonably be expected that rural and Northern Ontario francophones experience barriers when receiving care. However, the experience of physicians working in areas densely populated by francophones is largely unexplored. This paper identifies barriers experienced by French-speaking and Non-French-speaking rural and Northern Ontario physicians when serving francophone patients. A series of key informant interviews were conducted with 18 family physicians practicing in rural and urban francophone communities of Northeastern Ontario. Interviews were analyzed using a thematic analysis process. Five categories of barrier were identified: (1) language discordance, (2) characteristics of francophone patients, (3) dominance of English in the medical profession, (4) lack of French-speaking medical personnel, and (5) physicians' linguistic (in)sensitivity. Some barriers identified were unique to Non-French-speaking physicians (eg language discordance, use of interpreters, feelings of inadequacy), some were unique to French-speaking physicians (eg limited French education and resources), and some were common to both groups (eg lack of French-speaking colleagues/staff, added time commitments, and the particularities of Franco-Ontarian preferences and culture). Healthcare providers and decision makers may take interest in these results. Although physicians were the focus of the present article, the barriers expressed are likely experienced by other healthcare providers, and thus the lessons learned from this article extend beyond the physician workforce. Efforts must be made to offer educational opportunities for physicians and other healthcare providers working in areas densely populated by

An aerial radiological survey was conducted from August 10-16, 1993, over a 78-square-kilometer (30-square-mile) area of the Portsmouth Gaseous Diffusion Plant and surrounding area located near Portsmouth, Ohio. The survey was performed at a nominal altitude of 46 meters (150 feet) with a line spacing of 76 meters (250 feet). A contour map of the terrestrial gamma exposure rate extrapolated to 1 meter above ground level was prepared and overlaid on a set of United States Geological Survey topographic maps of the area and an aerial photograph of the plant. The terrestrial gamma exposure rates varied from about 7 to 14 microroentgens per hour at 1 meter above the ground. Protactinium-234m was observed at six sites within the boundaries of the plant. At a seventh site, only uranium-235 was observed. No other man-made, gamma ray-emitting radioactive material was present in a detectable quantity, either on or off the plant property. Soil sample and pressurized ion chamber measurements were obtained at four locations within the survey boundaries to support the aerial data. The results of the aerial and ground-based measurements were found to agree within ± 7.5%

Full Text Available Maherabad prospect area, which is studied in detail, is the first porphyry Cu-Au mineralization in the east of Iran. Based on relation of mineralization with subvolcanic intrusive bodies mostly monzonitic with porphyry texture, extent and types of alteration including potassic, sericitic- potassic, quartz- sericite- carbonate- pyrite, quartz- carbonate- pyrite, silicification- propylitic, propylitic, stockwork mineralization, assemblages hypogene mineralization including pyrite, chalcopyrite, bornite and magnetite and high anomalies of Cu and Au, Mineralization is porphyry Cu-Au-type. MA-I area, which is covered by regolith from its surrounding is the most important section of mineralization in the region because of intensive of quartz-sericite-carbonate-pyrite alteration and very high dense quartz-sulfide veinlets. IP/RS and ground magnetic surveys were conducted in the MA-I prospect area and its surrounding plain. Drilling on the IP suede section anomaly resulted to the recognition of sulfide mineralization in on extensive area under the regolith. Surface and underground detailed studies of geology, alteration, mineralization and geochemistry confirm the extension of covered mineralization to the south and west of the area. Based on the ground magnetic anomaly, the center of mineralization system, potassic zone, to the southwest of the area was recognized. Quartz0sericite-carbonate-pyrite alteration zone, which is located around the potassic zone, has very low magnetic response. IP/RS and ground magnetic surveys in a broader area than before are strongly recommended.

The concentrations, profiles, sources and spatial distribution of polycyclic aromatic hydrocarbons (PAHs) were determined in 40 surface soil samples collected from Beijing, Tianjin and surrounding areas, North China in 2007, and all sampling sites were far from industrial areas, roadsides and other pollution sources, and across a range of soil types in remote, rural villages and urban areas. The total concentrations of 16 PAHs ranged from 31.6 to 1475.0 ng/g, with an arithmetic average of 336.4 ng/g. The highest PAH concentrations were measured in urban soils, followed by rural village soils and soils from remote locations. The remote-rural village-urban PAH concentration gradient was related to population density, gross domestic product (GDP), long-range atmospheric transport and different types of land use. In addition, the PAH concentration was well correlated with the total organic carbon (TOC) concentration of the soil. The PAH profile suggested that coal combustion and biomass burning were primary PAH sources. - The concentration, profiles and possible sources of PAHs in Beijing, Tianjin and surrounding area soils were studied and related to population density and gross domestic product (GDP).

1994-02-01

An in situ survey of the area surrounding the Paducah Gaseous Diffusion Plant was conducted between May 17 and 24, 1990. The survey consisted of in situ measurements and of ground sampling. A High Purity Germanium detector was used for the in situ measurements. The ground samples were taken to the, laboratory at EG ampersand G Energy Measurements, Inc., in Santa Barbara, California, for a radionuclide assay on a laboratory system. Results of the in situ measurements found evidence of naturally occurring radioisotopes, cesium-137 from international fallout, and some evidence of anomalous uranium-238. The soil sampling results show only the presence of naturally occurring radioisotopes, cesium-137, and also anomalous uranium-238

The report surveys the historical background and the current situation in Ontario, and makes recommendations for an organized safety program. (L.L.)

An economic analysis of small-scale cogeneration using forest biomass and sawmill residuals in northern Ontario

International Nuclear Information System (INIS)

Beke, N.L.

1994-01-01

The economic feasibility of using biomass for cogeneration in northern Ontario was investigated and the institutional factors that may affect establishment and operation of cogeneration facilities were determined. Two fuel sources for a cogeneration plant were evaluated: forest materials and sawmill residuals. To establish and operate a cogeneration plant, the policies of the Ontario Ministry of Natural Resources and Ontario Hydro needed to be analyzed. Some of the benefits of using sawmill residuals for cogeneration were identified and an inventory of sawmill residuals was compiled. The welfare effects of three pricing schemes for non-utility generated electricity are described using a neoclassical welfare model. This model is further extended to include the effects of subsidizing public utilities and using biomass to generate electricity. A competitive market for electricity generation and relating pricing structure was also examined. The results of the capital budget for the cogeneration facility indicated that by using sawmill residuals and chipped forest biomass as fuel for cogeneration, internal rates of return would be 22.7% and 8.7% and net present values would be $8,659,870 and $1,867,822, respectively. This implied that using sawmill residuals for cogeneration fuel would be both profitable and would help to reduce possible harmful effects that current dumping practices may have on the surrounding ecosystem. 84 refs., 17 figs., 14 tabs

An aerial radiological survey was conducted over the former Atomic Energy Commission Test Site at the Salmon Site and surrounding area between April 20 and May 1, 1992. The Salmon Site is located in Lamar County, Mississippi, approximately 20 miles southwest of Hattiesburg, Mississippi. The purpose of the survey was to measure and document the gamma-ray environment of the Salmon Site and adjacent lands. A contour map showing gamma radiation exposure rates at 1 meter above ground level was constructed from the aerial data and overlaid on a rectified aerial photograph of the area. The exposure rates within the area are between 5 and 8 μR/h. The reported exposure rates include a cosmic-ray contribution estimated to be 3.7 μR/h. Radionuclide assays of soil samples and in situ measurements, taken with a pressurized ion chamber and a high-purity germanium detector, were obtained at 4 locations within the survey boundaries. These measurements were taken in support of and are in agreement with the aerial data

Restructuring in Ontario : electricity sector reform

International Nuclear Information System (INIS)

Pospisil, S.

2004-01-01

Ontario's electricity reform strategy was outlined along with challenge facing Ontario's electricity supply and demand with particular focus on the issue of replacing coal-fired generation. According to reports by the Independent Electricity Market Operator, short-term reserve margins were higher in 2004 than they were in 2003 due to the return to service of some nuclear generating units and planned capacity additions. Ontario's long-term supply and demand situation was also examined. It was noted that lenders hesitate to finance the expansion of generation companies selling into the spot market. Many lenders are requiring that half of the project's output be sold in advance on contract. Other challenges include Ontario's aging generation infrastructure and rising energy prices. The presentation included graphs that compared electricity costs for residential and small business customers across various provinces and states. The main supply and conservation challenges revolve around the large investments required by 2020 to replace coal plants, retire nuclear plants and projected load growth. Ontario's current generation capacity is 154 TWh and the mix is represented by 40 per cent nuclear, 25 per cent coal, 25 per cent hydro, 8 per cent natural gas, 1 per cent oil, and 1 per cent biomass and other renewable energy sources. This paper also addressed the issue of coal generation and air pollution and emphasized the importance of looking at the broad externalities associated with air emissions. tabs., figs

Creating a competitive electricity market in Ontario - The energy consumer perspective

International Nuclear Information System (INIS)

Ford, M.

1997-01-01

The large consumers' perspective on the Ontario Government's decision to delay action on restructuring the electric power industry was provided, and recommendations were offered as to the best course of action that the Government ought to take. Ontario Hydro's proposal to restructure itself into separate generation, transmission and retail corporations, and to introduce competition into the Corporation was attacked as unworkable, in that it could not help but encourage price manipulation. The large consumer group also argued that retail distribution in Ontario needs major rationalization without an Ontario Hydro presence. In place of the Ontario Hydro proposal the Association of Major Power Consumers in Ontario (AMPCO) recommends a separate transmission system including an independent system operator, a restructuring of local distribution within a definite time frame and consistent criteria, to be worked out by municipal utilities and Ontario Hydro Retail, and establishment of a Transition Authority independent of Ontario Hydro with a mandate to carry out these changes. While the Ontario Government appears to be unlikely to undertake such a'risky' initiative at this stage of its mandate, significant change, including competition, remains inevitable. It is not a question of whether, but when a fully competitive energy market in Ontario will become a reality. tabs., figs

Information support of territorial wildlife management of Lake Baikal and the surrounding areas (Russia)

Science.gov (United States)

Lesnykh, Svetlana

2013-04-01

The UNESCO World Heritage Committee inscribed Lake Baikal in the World Heritage List under all four natural criteria as the most outstanding example of a freshwater ecosystem. It is the oldest and deepest lake in the world, which is the main freshwater reserve surrounded by a system of protected areas that have high scientific and natural values. However, there is a conflict between three main interests within the territory: the preservation of the unique ecosystem of the lake and its surrounding areas, the need for regional economic development, and protection of interests of the population, living on the shores of Lake Baikal. Solutions to the current challenges are seen in the development of control mechanisms for the wildlife management to ensure sustainable development and conservation of lake and the surrounding regions. For development mechanisms of territorial management of the complex and valuable area it is necessary to analyze features of its functioning and self-control (adaptable possibilities), allowing ecosystems to maintain their unique properties under influence of various external factors: anthropogenic (emissions, waste water, streams of tourists) and natural (climate change) load. While determining the direction and usage intensity of the territory these possibilities and their limits should be considered. Also for development of management strategy it is necessary to consider the relation of people to land and water, types of wildlife management, ownership, rent, protection from the negative effects, and etc. The relation of people to the natural area gives a chance to prioritize the direction in the resource use and their protection. Results of the scientific researches (reaction of an ecosystem on influence of various factors and system of relations to wildlife management objects) are the basis for the nature protection laws in the field of wildlife management and environmental protection. The methodology of legal zoning of the territory was

Lake Sturgeon, Acipenser fulvescens, movements in Rainy Lake, Minnesota and Ontario

Science.gov (United States)

Adams, W.E.; Kallemeyn, L.W.; Willis, D.W.

2006-01-01

Rainy Lake, Minnesota-Ontario, contains a native population of Lake Sturgeon (Acipenser fulvescens) that has gone largely unstudied. The objective of this descriptive study was to summarize generalized Lake Sturgeon movement patterns through the use of biotelemetry. Telemetry data reinforced the high utilization of the Squirrel Falls geographic location by Lake Sturgeon, with 37% of the re-locations occurring in that area. Other spring aggregations occurred in areas associated with Kettle Falls, the Pipestone River, and the Rat River, which could indicate spawning activity. Movement of Lake Sturgeon between the Seine River and the South Arm of Rainy Lake indicates the likelihood of one integrated population on the east end of the South Arm. The lack of re-locations in the Seine River during the months of September and October may have been due to Lake Sturgeon moving into deeper water areas of the Seine River and out of the range of radio telemetry gear or simply moving back into the South Arm. Due to the movements between Minnesota and Ontario, coordination of management efforts among provincial, state, and federal agencies will be important.

Cross currents : hydroelectricity and the engineering of northern Ontario

Energy Technology Data Exchange (ETDEWEB)

Manore, J.L. [Calgary Univ., AB (Canada)

1999-05-01

The history of hydroelectric development in northern Ontario was reviewed and analysed with special emphasis on the developments along the Mattagami and Abitibi Rivers. The objective was to examine the important factors that shaped modern hydroelectric development in Canada. System builders, the privately owned Nesbitt Thomson Company, the publicly owned Hydro Electric Power Corporation of Ontario and the eventual evolution of the single power system under Ontario Hydro are chronicled. Broad historical themes such as the technological impacts, regionalism, indigenous rights, plus environmental and economic issues are examined, in addition to an appreciation of the importance of electricity in the manufacturing sector of Ontario, the impact of hydroelectric development on the northern environment and on the northern First Nations, who rely on rivers for their subsistence. Until fairly recently, government policies and interpretations of law often excluded the recognition of Aboriginal uses of river systems, thereby limiting First Nations` peoples ability to practice traditional ways of life. In essence, the book is an account of how the northeastern power system in Ontario shaped the social, political and natural environments and how the development of northeastern power sources by southern power developers shaped the regional interactions between Ontario`s north and south. refs., figs.

Is there a future for coal in Ontario?

International Nuclear Information System (INIS)

Davies, G.

2004-01-01

This PowerPoint presentation examined the efficacy of a governmental decision in 2003 to close all Ontario coal stations by 2007. Coal currently represents one quarter of Ontario's energy and capacity. Projected supply and demand gaps for Ontario were presented for up to 2020. Ontario's supply options were outlined. It was noted that between $30 and $40 billion in investment in the electricity sector will be needed over the next 10 to 15 years. It was observed that closing coal plants may reduce pollution by 6 per cent at a cost of $2 billion. More than half the smog affecting Ontario comes from the United States, while much of the remaining half is caused by transportation emissions. Details of energy strategies related to coal in the United States were discussed. New coal power plant technologies include supercritical combustion; advanced air pollution control; circulating fluidized bed combustion and integrated coal gasification combined cycles. Coal power plant performance criteria were presented. Various research programs in the United States were reviewed, and roadmap performance targets were presented. It was concluded that high prices and uncertainty for natural gas fired options may reinforce views on the need to rethink coal closures. A strategy was recommended in which Ontario pursued economic options for reducing emissions across all sectors. New investments in latest and best technology for emissions reduction in Ontario's coal-fired stations were recommended, as well as a North American agreement on clean air, and increased Canadian participation in U.S. technology development efforts for clean coal and zero emissions plants by 2025. tabs., figs

The enforcement order for the law for arrangement of surrounding areas of power generating facilities

International Nuclear Information System (INIS)

1984-01-01

The enforcement order provides for grants concerning the arrangement of various public facilities in the areas surrounding a power generating facility; the public facilities in the arrangement for which the grants are given include communication, recreation activities, environmental sanitation, culture, medicine, etc. The prefectural governor concerned submits his plan for the arrangement to the Government, which then decides on the grants. Then, the grants are given to local governments concerned. The sums of the grants are determined on the basis of the output, construction cost of the nuclear power facility. (Mori, K.)

Design, construction and operation of Ontario Hydro's CANDU plants

International Nuclear Information System (INIS)

Campbell, P.G.

1981-06-01

Ontario Hydro has been producing electricity commercially from nuclear power since 1968, using CANDU reactors which have proved enormously successful. The 206-MW Douglas Point station, nearly 10 times larger than the first Canadian power reactor, NPD-2, resulted from a cooperative effort between Atomic Energy of Canada Ltd., the provincial government of Ontario, and Ontario Hydro. This approach led to a basic working relationship between the parties, with Ontario Hydro acting as project manager and builder, and AECL acting as consultant with respect to the nuclear components. Before Douglas Point was fully commissioned Ontario Hydro was ready to commit itself to more nuclear stations, and work was started on the four-unit Pickering nuclear generating station. Multi-unit stations were adopted to achieve economies of scale, and the concept has been retained for all subsequent nuclear power plants constructed in the province. The organization of Ontario Hydro's project management, construction, and operation of nuclear generating stations is described. Performance of the existing stations and cost of the power they produce have been entirely acceptable

Further studies of the effects of smoke from towns upon vegetation in the surrounding areas

Crowther, C; Steuart, D W

1914-01-01

The relative degree of air pollution was measured in various parts of Leeds and in the surrounding semi-urban and rural areas to a distance in some directions of seven miles from the center of the city. Subsequently, an attempt was made to directly measure the effects of the pollution upon crops grown in various parts of the area investigated. Reasonably well controlled experiments were carried out to examine the effects on growth rate of grass and buckwheat. Results were suggestive but not conclusive. Attempts were made to determine which grasses do best in smoky regions by examining meadows while in flower. Many anecdotal reports are given of the negative effects of air pollution on specific crops, as well as the decreased vigor and hardiness of plants in general. 4 tables.

Heat wave generates questions about Ontario's generation capacity

International Nuclear Information System (INIS)

Horne, D.

2005-01-01

Concerns regarding Ontario's power generation capacity were raised following a major blackout which occurred in August 2003. Power demand reached 26,170 MW during the weeks leading to the blackout, forcing the Independent Electricity System Operator (IESO) to ask residents to reduce electricity use during the day. The grid operator had also issued a forecast that Toronto could face rolling blackouts during times of heavy power demand. Ontario power consumption records were set in June and July of 2003 due to a heat wave, with hourly demand exceeding 25,000 MW on 53 occasions. Ontario was forced to import up to 3,400 MW (13 per cent of its power needs) from neighbouring provinces and the United States. During that period, the price of power had risen sharply to over 30 cents a kilowatt hour, although household consumers were still charged in the 5 to 10 cent range per kilowatt hour. However, it was noted that taxpayers will eventually bear the cost of importing power. The IESO noted that importing electricity is cheaper than the generation available in Ontario and that it is more economical to import, based on the market clearing price of all generators. In 2004, the IESO purchased 6 per cent of their electricity from the United States. That figure is expected to increase for 2005. Ontario generators produced 26.9 million MWh more in the summer of 2005 than during the same period in 2004 to meet electricity demand levels. It was noted that although importing power presently meets peak demand, the IESO agrees there is a need for new generation within Ontario. In addition to restarting Ontario's Pickering and Bruce nuclear facilities, more than 3,300 MW of new gas-fired generation is under construction or approved, and more than 9,000 MW are in various stages of approval. This paper discussed the effect of high energy costs on industry and Ontario's ability to meet future electricity demand in comparison to neighbouring jurisdictions.

2006-01-01

A survey was conducted among members of the Ontario Energy Board's (OEB) various stakeholder groups in order to measure the Board's performance and to help the Board identify areas for improvement in the way it operates. The survey included telephone interviews with consumer groups, advocacy groups, the energy sector, electricity and gas distributors, financial organizations as well as other stakeholders. The topics addressed in the survey were key energy issues and priority issues; the perceived role of the OEB; the OEB strengths and weaknesses; the importance of various OEB functions; the overall performance of the OEB; an evaluation of OEB communication with industry and consumers; an evaluation of service quality; and, awareness and participation in regulatory policy initiatives. Respondents used a 10-point scale in their evaluation. This report presented the main findings and their interpretations. Major stakeholders identified electricity supply issues and the price of electricity as being the most important energy issues facing Ontario. This report also presented the detailed findings for questions regarding the lack of generator capacity, policy stability, the coal phase out program, electricity blackouts, conservation, electricity restructuring and investment. The major finding of the survey was an overall increase in satisfaction with the OEB's performance. It was suggested that the OEB can improve in timeliness and providing consumer information. The major areas of strength were found to be its professionalism in conducting hearings and the fairness of the Board's decisions and regulations. tabs

Cole, D.C.; Kearney, Jill; Sanin, L.H.; Leblanc, Alain; Weber, J.P.

2004-01-01

We conducted two surveys of Ontario (Canada) fishers: a stratified sample of licensed anglers in two Lake Ontario communities (anglers, n=232) and a shore and community-based sample in five Great Lakes' Areas of Concern (AOC eaters, n=86). Among the 176 anglers consuming their catch, the median number of sport-fish meals/year was 34.2 meals and 10.9, respectively, in two communities, with a mean blood total mercury level among these sport-fish consumers of 2.8 μg/L. The vast majority of fish eaten by AOC eaters was from Ontario waters (74%). For AOC eaters, two broad country-of-origin groups were assembled: Euro-Canadians (EC) and Asian-Canadians (AC). EC consumed a median of 174 total fish meals/year and had a geometric mean total mercury level of 2.0 μg/L. Corresponding AC figures were 325 total fish meals/year and 7.9 μg/L. Overall, mercury levels among AOC eaters were higher than in many other Great Lakes populations but lower than in populations frequently consuming seafood. In multivariate models, mercury levels were significantly associated with levels of fish consumption among both anglers and EC AOC eaters. Given the nutritional and social benefits of fish consumption, prudent species and location choices should continue

Full Text Available In response to the growing role of personal support workers (PSWs in the delivery of health care services to Ontarians, the Ontario government has moved forward with the creation of a PSW registry. This registry will be mandatory for all PSWs employed by publicly funded health care employers, and has the stated objectives of better highlighting the work that PSWs do in Ontario, providing a platform for PSWs and employers to more easily access the labour market, and to provide government with information for human resources planning. In this paper we consider the factors that brought the creation of a PSW registry onto the Ontario government’s policy agenda, discuss how the registry is being implemented, and provide an analysis of the strengths and weaknesses of this policy change.

An aerial radiological survey was conducted over the Seabrook Nuclear Station, Seabrook, New Hampshire, during the period 6 July through 14 July 1988. The purpose of the 247-square-kilometer (96-square-mile) survey was to document the terrestrial gamma environment of the station and surrounding area. An exposure rate contour map at 1 meter above ground level (AGL) was constructed from the gamma data and overlaid on an aerial photograph and map of the area. Exposure rates measured in the area typically ranged form 9 to 12 microroentgens per hour (μR/h). In areas where water shielded the earth, lower exposure rates were measured. Ground-based exposure rate measurements and soil samples were obtained to support the aerial data. Oblique aerial photographs of the station were also acquired during the survey. 9 refs., 5 figs., 1 tab

Determination of precise hypocenter location is very important in order to provide information about subsurface fault plane and for seismic hazard analysis. In this study, we have relocated hypocenter earthquakes in Eastern part of Java and surrounding areas from local earthquake data catalog compiled by Meteorological, Climatological, and Geophysical Agency of Indonesia (MCGA) in time period 2009-2012 by using the double-difference method. The results show that after relocation processes, there are significantly changes in position and orientation of earthquake hypocenter which is correlated with the geological setting in this region. We observed indication of double seismic zone at depths of 70-120 km within the subducting slab in south of eastern part of Java region. Our results will provide useful information for advance seismological studies and seismic hazard analysis in this study

More than energy: Ontario Hydro final annual report, January 1998 - March 1999

International Nuclear Information System (INIS)

1999-01-01

Ontario Hydro ceased operations on March 31, 1999 and its assets and functions were transferred by provincial statute to two successor corporations: Ontario Power Generation Corp. (OPG) and Ontario Hydro Services Inc. Its functions were also transferred to the Independent Electricity Market Operator and the Electrical Safety Authority, two not-for-profit agencies. The original act defining Ontario Hydro was replaced by the Energy Competition Act, 1998. Until the demerger of the company on April 1, 1999, Ontario Hydro served 108 direct industrial clients, almost one million retail clients and 255 municipal utilities. Ontario Power Generation inherited Ontario Hydro's generating portfolio, making it one of the largest power producers in North America in terms of installed capacity. The OPG system includes 69 hydroelectric stations, three nuclear sites, and six operating fossil fueled stations. Total installed system capacity is approximately 31,000 megawatts, and Ontario Hydro's total sales in 1998 were almost 139 terawatt hours. Ontario Hydro Services Company is an energy services-based transmission and distribution company. It owns and maintains 29,000 km of transmission lines, 114,700 km of distribution lines, 245 km of high-voltage underground cable, 256 transformer stations, 928 distribution and regulation stations, and 250 microwave stations. It also retains the retail business held by Ontario Hydro, which serves over 950,000 clients, and the transmission and generating business for 23 remote communities in Northern Ontario

1988-04-01

A case-controlled epidemiologic study of multiple sclerosis (MS) was carried out in London, Ontario, and its surrounding Middlesex County for the period 1974-1983. The prevalence rates for clinically definite/probable MS on January 1, 1984 were 94/100,000 for the city and 91/100,000 for the county. The estimated annual incidence rate for the decade 1974-83 was 3.4/100,000. The female-to-male sex ratio was 2.5:1. A familial history of MS was recorded in 14.4% of close relatives and a total of 17% when distant relatives are included. The MS group is predominantly of British (70%) and European (23%) origin. The urban-rural residence pattern analysis indicates no significant regional influence on the risk of developing MS.

Countering school bullying: An analysis of policy content in Ontario and Saskatchewan

Full Text Available The incidence of extreme school violence as a direct consequence of bullying among peers, exacerbated by vast media attention, has caused educational institutions worldwide to put bullying intervention and prevention strategies into operation. This study focused on an overview of two provincewide antibullying incentives in the Canadian provinces of Ontario and Saskatchewan, and an analysis of the quality of their respective antibullying policies. An itemized list of beneficial practices for bullying intervention and prevention originated from Smith, Smith, Osborn and Samara (2008’s scoring scheme. The scoring scheme was adapted to the current study by linking research-based program elements that have been found to be effective in reducing school bullying to a content analysis of both provincial frameworks. The final scoring scheme comprised a total of 39 criterions, divided into five categories: Defining Bullying Behaviors, Establishing a Positive School Climate, Disseminating, Monitoring and Reviewing Policy, Reporting and Responding to Bullying, and Involving the Broader Community. Results showed that policies contained a total average of 60% of the criterions in Ontario, and 59% in Saskatchewan. The conclusion of this study observes from policy lenses key essentials of bullying intervention and prevention initiatives in elementary and secondary educational settings. Recommendations are proposed to bridge the gap between areas that have received extensive attention and areas that have received less treatment in bullying intervention and prevention endeavors, using the content of Ontario and Saskatchewan policies as a basis for discussion.

Ontario's changing electrical sector : implications for air quality and human health

International Nuclear Information System (INIS)

Perrota, K.; De Leon, F.

1999-03-01

Concerns regarding the changes to Ontario's electricity sector and the impacts that these changes may have on the environment and public health are discussed. Two of the major changes include the implementation of the Nuclear Asset Optimization Plan, and the introduction of competition to Ontario's electrical market. Both changes could have profound impacts on air quality in Toronto and the rest of Ontario. This report recommends that the Ontario Minister of Environment and the Ontario Minister of Energy, Science and Technology establish: a regulatory framework to ensure that competition in Ontario's electrical sector does not lead to greater reliance on coal-fired generating stations and further degradation of air quality, human health and the environment in Toronto and the rest of southern Ontario; annual air emission caps for the entire electrical sector to limit the volume of air pollutants released each year; a renewable energy standard which defines the percentage of electricity that must be generated with renewable energies by electrical suppliers serving Ontario consumers; and a public benefit fund to support the promotion of energy conservation and the development of renewable energies with a surcharge on the transmission of electricity. 35 refs., 5 tabs

Axford, D.

2003-01-01

A brief introduction of Nexen Chemicals, one of the largest producers of sodium chlorate in the world, was offered, and a map displaying its locations throughout the world was displayed. Nexen is one of Canada's largest independent oil and gas producers, while Nexen Marketing is involved in the marketing of natural gas in North America. In January 2001, the deregulated market opened in Alberta. High natural gas prices, generation shortages, high prices in California and an upcoming provincial election all combined to complicate the situation. A high degree of volatility characterized the market. A chart displaying weekly average Alberta power and gas prices from Jan 2002 to 13 Oct 2002 was shown. In Ontario, the market opened in May 2002, and the demand growth rate was in the 1 to 2 per cent range. The author indicated that approximately 20 per cent of homeowners in Ontario have signed deals with retailers, contrary to Alberta where very few have done so. A similar chart displaying weekly average Ontario power prices was presented. The issues in Ontario are: consistency in policy, increase market transparency, transmission / distribution price flexibility, overall transmission / distribution to industrial consumers high, and increasing costs of the system operator. In Alberta, the issues are: government intent, congestion management issues, and billing settlement errors that continue. The opportunities offered by a deregulated market include process responsiveness which is rewarded, the ability to look in forward prices when prices fit margin requirement, and gives companies the opportunity to participate in the development of the market. Various charts were also displayed to further illustrate the market in both Alberta and Ontario. figs

Fifteen years of radioactive waste management at Ontario Hydro

Carter, T.J.; Rao, P.K.M.

1985-01-01

Ontario Hydro is a large Canadian utility producing 84% (7394 MWe) of the Nuclear Electricity generated in Canada. The low- and intermediate-level radioactive wastes generated by the Ontario Hydro program are currently being managed at the Bruce Nuclear Power Development with various volume reduction, packaging and interim storage systems. Ontario Hydro also owns and operates a radioactive waste transportation system. Studies are in progress for final disposal of these wastes in a suitable geology in Ontario. Since its inception in 1971, Ontario Hydro's radioactive waste management program has evolved into providing a full fledged radioactive waste management capability to the utility's two nuclear generation centres at Pickering and Bruce, and later in the decade, to Darlington. This paper summarizes the various developments in this program; highlights the major facilities both in-service and planned to be built; reviews the experiences gained over fifteen years of in-house waste management; and discusses the proposed reorientation towards ultimate disposal of these wastes. 2 refs., 8 figs., 1 tab

The potential of solar PV in Ontario

International Nuclear Information System (INIS)

McMonagle, R.

2005-01-01

Canada has lagged behind other industrialized nations in the growth of solar energy markets. Currently, over 78 per cent of the global market for solar energy is for grid-connected applications where power is fed into the electrical distribution network. Less than 3.5 per cent of the Canadian solar market is grid-connected. This report investigated the potential size of the photovoltaic (PV) market in Ontario given adequate support from both governments and utilities. The forecast was based on sustainable growth levels that the solar industry as a whole might maintain over an extended period of time. It was suggested that it is technically feasible to install over 3000 MW of PV in single, detached homes in the province, which could generate over 3200 GWh each year. If the right policy conditions were put in place, the technical potential for PV on all buildings in Ontario is over 14,000 MW by 2025, which would generate over 13,000 GWh annually. Support mechanisms such as the Advanced Renewable Tariff (ART) or Standard Offer Contracts (SOC) will enable the PV industry to build capacity. Future markets for PV include new homes, commercial buildings and the existing housing stock. With a properly designed system, it is forecasted that the deployment of PV by 2025 could result in the involvement of 400,000 homes with over 1200 MW of installed capacity and over 290 MW installed annually by 2025. Recommendations to Ontario Power Authority's (OPA) report supply mix report focused on the use of SOCs as the appropriate support mechanism to start building solar capacity in Ontario, as projections using SOCs would see Ontario following the growth patterns of other nations. It was concluded that the OPA report does not acknowledge the current growth rates of PV globally, nor does it fully consider the potential of PV in Ontario. 9 refs., 8 figs

A heuristic simulation model of Lake Ontario circulation and mass balance transport

Science.gov (United States)

McKenna, J.E.; Chalupnicki, M.A.

2011-01-01

The redistribution of suspended organisms and materials by large-scale currents is part of natural ecological processes in large aquatic systems but can contribute to ecosystem disruption when exotic elements are introduced into the system. Toxic compounds and planktonic organisms spend various lengths of time in suspension before settling to the bottom or otherwise being removed. We constructed a simple physical simulation model, including the influence of major tributaries, to qualitatively examine circulation patterns in Lake Ontario. We used a simple mass balance approach to estimate the relative water input to and export from each of 10 depth regime-specific compartments (nearshore vs. offshore) comprising Lake Ontario. Despite its simplicity, our model produced circulation patterns similar to those reported by more complex studies in the literature. A three-gyre pattern, with the classic large counterclockwise central lake circulation, and a simpler two-gyre system were both observed. These qualitative simulations indicate little offshore transport along the south shore, except near the mouths of the Niagara River and Oswego River. Complex flow structure was evident, particularly near the Niagara River mouth and in offshore waters of the eastern basin. Average Lake Ontario residence time is 8 years, but the fastest model pathway indicated potential transport of plankton through the lake in as little as 60 days. This simulation illustrates potential invasion pathways and provides rough estimates of planktonic larval dispersal or chemical transport among nearshore and offshore areas of Lake Ontario. ?? 2011 Taylor & Francis.

Ontario Hydro presently operates 18 CANDU reactors in the province of Ontario, Canada. All of these reactors are of the CANDU Pressurized Heavy Water design, although their design features differ somewhat reflecting the evolution that has taken place from 1971 when the first Pickering unit started operation to the present as the Darlington units are being placed in service. Over the last three years, two significant neutronic transients took place at the Pickering Nuclear Generating Station 'A' (NGS A) one of which resulted in a number of fuel failures. Both events provided valuable lessons in the areas of operational safety, fuel performance And accident analysis. The events and the lessons learned are discussed in this paper

Ontario Select Committee on Alternative Fuel Sources : Final Report

International Nuclear Information System (INIS)

Galt, D.

2002-06-01

On June 28, 2001, the Ontario Legislative Assembly appointed the Select Committee an Alternative Fuel Sources, comprised of representatives of all parties, with a broad mandate to investigate, report and offer recommendations with regard to the various options to support the development and application of environmentally sustainable alternatives to the fossil fuel sources already existing. The members of the Committee elected to conduct extensive public hearings, conduct site visits, attend relevant conferences, do some background research to examine a vast number of alternative fuel and energy sources that could be of relevance to the province of Ontario. A discussion paper (interim report) was issued by the Committee in November 2001, and the present document represents the final report, containing 141 recommendations touching 20 topics. The information contained in the report is expected to assist in the development and outline of policy and programs designed to specifically support alternative fuels and energy sources and applicable technologies. Policy issues were discussed in Part A of the report, along with the appropriate recommendations. The recommendations on specific alternative fuels and energy sources were included in Part B of the report. It is believed that the dependence of Ontario on traditional petroleum-based fuels and energy sources can be reduced through aggressive action on alternative fuels and energy. The benefits of such action would be felt in the area of air quality, with social, and economic benefits as well. 3 tabs

Brittanie LaBelle

2018-01-01

Full Text Available Rural patients with opioid use disorder (OUD face a variety of barriers when accessing opioid agonist therapy (OAT and psychiatric services, due to the limited supply of physicians and the vast geographic area. The telemedicine allows for contact between patients and their physician—regardless of physical distance. Objective. We characterize the usage of telemedicine to deliver psychiatric services to patients with OUD in Ontario, as well as traits of treatment-seeking patients with opioid dependence and concurrent psychiatric disorders. Methodology. A retrospective cohort study was conducted using an administrative database for patients who received psychiatric services via telemedicine between 2008 and 2014 and who also had OUD. Results. We identified 9,077 patients with concurrent opioid use and other mental health disorders who had received psychiatric services via telemedicine from 2008 to 2014; 7,109 (78.3% patients lived in Southern Ontario and 1,968 (21.7% in Northern Ontario. Telemedicine was used more frequently to provide mental health services to patients residing in Northern Ontario than Southern Ontario. Conclusion. Telemedicine is increasingly being utilized throughout Ontario for delivering mental health treatment. There is an opportunity to increase access to psychiatric services for patients with opioid dependence and concurrent psychiatric disorders through the use of the telemedicine.

Cross currents : hydroelectricity and the engineering of northern Ontario

International Nuclear Information System (INIS)

Manore, J.L.

1999-01-01

The history of hydroelectric development in northern Ontario was reviewed and analysed with special emphasis on the developments along the Mattagami and Abitibi Rivers. The objective was to examine the important factors that shaped modern hydroelectric development in Canada. System builders, the privately owned Nesbitt Thomson Company, the publicly owned Hydro Electric Power Corporation of Ontario and the eventual evolution of the single power system under Ontario Hydro are chronicled. Broad historical themes such as the technological impacts, regionalism, indigenous rights, plus environmental and economic issues are examined, in addition to an appreciation of the importance of electricity in the manufacturing sector of Ontario, the impact of hydroelectric development on the northern environment and on the northern First Nations, who rely on rivers for their subsistence. Until fairly recently, government policies and interpretations of law often excluded the recognition of Aboriginal uses of river systems, thereby limiting First Nations' peoples ability to practice traditional ways of life. In essence, the book is an account of how the northeastern power system in Ontario shaped the social, political and natural environments and how the development of northeastern power sources by southern power developers shaped the regional interactions between Ontario's north and south. refs., figs

Odoi, A; Martin, S W; Michel, P; Holt, J; Middleton, D; Wilson, J

2004-10-01

Giardiasis surveillance data as well as drinking water, socioeconomic and land-use data were used in spatial regression models to investigate determinants of the geographic distribution of endemic giardiasis in southern Ontario. Higher giardiasis rates were observed in areas using surface water [rate ratio (RR) 2.36, 95 % CI 1.38-4.05] and in rural areas (RR 1.79, 95 % CI 1.32-2.37). Lower rates were observed in areas using filtered water (RR 0.55, 95 % CI 0.42-0.94) and in those with high median income (RR 0.62, 95 % CI 0.42-0.92). Chlorination of drinking water, cattle density and intensity of manure application on farmland were not significant determinants. The study shows that waterborne transmission plays an important role in giardiasis distribution in southern Ontario and that well-collected routine surveillance data could be useful for investigation of disease determinants and identification of high-risk communities. This information is useful in guiding decisions on control strategies.

Runnalls, O.J.C.

1981-01-01

This report traces the Ontario uranium mining industry from the first discovery of uranium north of Sault Ste. Marie through the uranium boom of the 1950's when Elliot Lake and Bancroft were developed, the cutbacks of the 1960s, the renewed enthusiasm in exploration and development of the 1970s to the current position when continued production for the domestic market is assured. Ontario, with developed mines and operational expertise, will be in a position to compete for export markets as they reopen. The low level of expenditures for uranium exploration and the lack of new discoveries are noted. The report also reviews and places in perspective the development of policies and regulations governing the industry and the jurisdictional relationships of the Federal and Provincial governments

New rules for competition: Ontario to cap power plant emissions

International Nuclear Information System (INIS)

Anon.

1999-01-01

The Ontario government through the Dept. of the Environment announced on November 16, 1999 that it would cut the emissions from Ontario coal burning power plants that cause acid rain and smog. This announcement was a much anticipated clarification of the government's plans to clean up the power industry since the enactment of the Electricity Competition Act more than one year past. The announcement signals the beginning of a public discussion process between government and stakeholders on the environmental rules for electricity generation in Ontario. The Ontario government is expected to release draft regulations for controlling coal burning power plant emissions in the near future. Consulations with stakeholders on the regulations, as well as the rules for disclosure and labeling, are anticipated to begin in a few months. The announcement set out four principles for environmental performance in the competitive electricity market. Anti-smog requirements will be included in the stringent environmental requirements to be built into Ontario's new, competitive electricity market. The strong measures which the government will put into place when the market opens later in 2000 include: (1) regulations to cut smog and acid gas emissions for all Ontario electricity generators on the grid - these regulations will include Ontario Hydro's voluntary nitrogen oxide limits; (2) emission performance standards to define maximum acceptable emission levels for all generators wanting to sell in the Ontario market; (3) a framework to support opportunities to make greater use of more efficient, environmentally responsible technologies; and (4) disclosure requirements to ensure that electricity consumers can understand the environmental implications of their purchasing decisions

1991-10-01

An aerial radiological survey was conducted during the period July 5 to 22, 1989, over an 83-square kilometer (32-square-mile) area surrounding the Saxton Nuclear Experimental Corporation (SNEC) facility which is owned by General Public Utilities and located near Saxton, Pennsylvania. The survey was conducted at a nominal altitude of 61 meters (200 feet) with line spacings of 91 meters (300 feet). A contour map of the terrestrial gamma exposure rate extrapolated to 1 meter above ground level (AGL) was prepared and overlaid on an aerial photograph and a set of United States Geological Survey (USGS) topographic maps of the area. The terrestrial exposure rates varied from about 9 to 11 microroentgens per hour (μR/h) over most of the survey area. The levels over the SNEC family did not differ from the exposure rates seen over the entire survey area. Cesium-137 (Cs-137) levels typical of worldwide fallout deposition were detected throughout the surveyed area. No other trends of Cs-137 were observed. Soil samples and pressurized ion chamber measurements were obtained at six locations within the survey boundaries to support the aerial data

Adaptation to climate change in the Ontario public health sector

Full Text Available Abstract Background Climate change is among the major challenges for health this century, and adaptation to manage adverse health outcomes will be unavoidable. The risks in Ontario – Canada’s most populous province – include increasing temperatures, more frequent and intense extreme weather events, and alterations to precipitation regimes. Socio-economic-demographic patterns could magnify the implications climate change has for Ontario, including the presence of rapidly growing vulnerable populations, exacerbation of warming trends by heat-islands in large urban areas, and connectedness to global transportation networks. This study examines climate change adaptation in the public health sector in Ontario using information from interviews with government officials. Methods Fifty-three semi-structured interviews were conducted, four with provincial and federal health officials and 49 with actors in public health and health relevant sectors at the municipal level. We identify adaptation efforts, barriers and opportunities for current and future intervention. Results Results indicate recognition that climate change will affect the health of Ontarians. Health officials are concerned about how a changing climate could exacerbate existing health issues or create new health burdens, specifically extreme heat (71%, severe weather (68% and poor air-quality (57%. Adaptation is currently taking the form of mainstreaming climate change into existing public health programs. While adaptive progress has relied on local leadership, federal support, political will, and inter-agency efforts, a lack of resources constrains the sustainability of long-term adaptation programs and the acquisition of data necessary to support effective policies.

Independent power and cogeneration in Ontario's new competitive electricity market

International Nuclear Information System (INIS)

Barnstable, A.G.

1999-01-01

The factors influencing the initial market pricing in the early years of Ontario's new electricity market were discussed with particular insight on the potential for near term development of independent power and cogeneration. The major factors influencing prices include: (1) no increase in retail prices, (2) financial restructuring of Ontario Hydro, (3) the Market Power Mitigation Agreement, (4) tighter power plant emissions standards, and (5) an electricity supply and demand balance. Generation competition is not expected to influence market pricing in the early years of the new electricity market. Prices will instead reflect the restructuring decisions of the Ontario government. The decision to have Ontario Power Generation Inc. (OPGI) as a single generator for Ontario Hydro's generation assets will ensure that average spot market pricing in the early market years will be close to a 3.8 c/kWh revenue cap

Some of the events precipitating this movement towards competition include the passing of the Energy Competition Act of 1998 (Bill 35), electricity deregulation, regulatory reform of the natural gas sector, and changes to the consumer protection legislation. The role of the Ontario Energy Board was also updated to bring it in line with the demands of the competitive marketplace. Among the new roles that the Board will assume are to facilitate competition, to maintain fair and reasonable rates, and to facilitate rational expansion. Another objective is to provide opportunities for including energy efficiency in government policies. Implications of the changes in the OEB's mandate for market participants were also discussed, including (1) regulated gas sales and delivery mechanisms, (2) transactional services, (3) contract restructuring, (4) consumer protection, (5) supervision of competitive market participants, and (6) market surveillance

None of the 8 species of bats in Ontario are considered as species at risk. However, all bats in Ontario are protected under the Fish and Wildlife Conservation Act. The Ontario Ministry of Natural Resources (MNR) is responsible for identifying significant wildlife habitat for bats, including hibernacula and maternity roosts. The MNR's role in wind development includes environmental assessments (EA) and surveys. The MNR bat guideline includes a summary of Ontario species, a literature review of research related to wind turbines and bats, and a review of methods for assessing and monitoring bats. Guideline development includes a bat working group responsible for obtaining data on risk factors and monitoring requirements. The MNR has determined that site selection is critical for minimizing potential impacts. Wind farm proponents can use MNR data, information, and maps for their site selection process. Information requirements include bat species data; habitat data; and meteorological data. The presence of risk factors results in a sensitivity rating. The MNR is also developing a site sensitivity mapping project in order to assist proponents in making siting decisions. All proposed sites are required to conduct pre-construction site surveys. Acoustic detectors and radar are used to determine bat activity at the site. Monitoring and mitigation strategies include selective wind turbine shutdown during key periods or weather conditions. tabs., figs.

Cement dust fall, concentration of total suspended particulate (TSP) and particulate less than 10 micron (PM10), were measured in different sites in the surrounding area of Tartus cement factory. The effects of cement dust emission on the growth of olive trees have been investigated. The results show that the dust fall, TSP and PM10 concentration were higher than The World Health Organization (WHO) standard at the factory site as well as in the surrounding area within 3 to 4 km in the diameter.The study shows that, the cement dust fall decreases the growth of olive trees by 34.5, 33 and 21% regarding the I, II, III sites respectively in comparison with the reference site. The branch length, branch weight, amount of chlorophyll and leaves quantity were decreased significantly. The mean weight of dust fall were 34.5, 26.4 and 10.9 g/m 2 on the leaves area at the site I, II, III respectively while the reference site has a value of 1.9 g/m 2 .(Author)

A look forward to the competitive landscape of Ontario's electricity supply

International Nuclear Information System (INIS)

Carr, J.

1998-01-01

The government of Ontario is a shareholder in Ontario Hydro and is responsible for ensuring that the public receives electricity service at the lowest, most prudent price. The current monopoly arrangement provides Ontario with a revenue stream that is predictable and amenable to control. However, the emerging restructuring of Ontario's electricity supply system will be strongly dependent on the direction determined by government policy. Other factors that will have significant influence on developments will be the restructuring initiatives outside the province, and the attractiveness of the electricity sector to investors. In November 1997, Ontario released a white paper by the Minister of Energy, Science and Technology, entitled 'Direction for change'. This document is a preliminary statement of potential policy regarding electricity restructuring in Ontario. Some of the key elements of the White Paper were: (1) the creation of a competitive market in the year 2000 for both wholesale and retail customers, (2) separating monopoly operations from competitive business activities throughout the electricity sector, (3) expanding the role on the Ontario Energy Board to give it regulatory power over the electricity sector, and (4) introducing measures to ensure environmental protection. Three other relevant reports were also released in December 1997: (1) Report of the Select Committee on Ontario Hydro Nuclear Affairs, (2) Ontario Energy Board Advisory Report on Legislative Change Requirements for Natural Gas Deregulation, and (3) Report of the Toronto Transition Team. The government policy indicated by these various reports appear to represent a careful balance of many conflicting interests and obligations. According to expert observers, the emerging policy appears to have the necessary technical, financial and political support to ensure a successful competitive electricity supply system in Ontario. 4 refs

The pupose of this study was to describe variations in incidence and resection rates of patients with oral cavity squamous cell carcinoma (SCC) in Ontario. All oral cavity SCCs in Ontario between 2003 and 2010 were identified from the Ontario Cancer Registry. Incidence and resection rates along with variations in care were compared by sociodemographic factors and Ontario health regions. The 8-year incidence rates for oral cavity SCC was 21.3 per 100,000 with variations by sex, age group, neighborhood income, and community size. Seventy-four percent of patients underwent an oral cavity cancer resection, of which 91% were at a regional head and neck cancer center. Variations in resection rates existed by region of residence and treatment. Oral cavity cancer incidence rates vary by sex, age, neighborhood income, community size, and health region. Resection rates vary by age and health region. Oral cavity cancer care is highly regionalized in Ontario. © 2015 Wiley Periodicals, Inc. Head Neck 38: 1113-1118, 2016. © 2015 Wiley Periodicals, Inc.

1980-09-01

This study investigated the socio-economic status of the parents of Ontario swimmers and parental expenditures, in terms of time and money, in support of competitive swimming. Questionnaires were mailed to a sample of 400 families of Ontario competitive swimmers. Spearman rho analyses were used to determine the relationships of membership fee, total cost and total time spent by the parents to the ability and age of the swimmer and the number of hours of practice and swim meets. Parents of Ontario competitive swimmers are upper middle class and devote a great deal of their time (X = 433 hours) and money (X = $744.00) annually to competitive swimming. Total expenditures and time spend by the parents were greater for those children were young and also for those whose children demonstrated greater ability (i.e., closer to Ontario record). Spearman rho analyses suggested that membership fees are not determined on the basis of age, number of practice hours or number of swim meets.

Dust Full Study In The Surrounding Area Of A Cement Factory And Determination Of The Major Elements Of The Dust Fall Using Neutron Activation Analysis (NAA)

International Nuclear Information System (INIS)

Meslmani, Y.; Al-Oudat, M.

2004-01-01

Dust fall of the Tartous cement factory and the surrounding area at the Syrian coast were measured. The results show that the dust fall concentrations were higher than the World Health Organization (WHO) Standard in the factory site as well as in the surrounding area within 5 to 6 km in the diameter. The value of the dust fall at the Reference sites was abut 4.5 t/km 2 /month and in the surrounding area of the factory values reached between 18 and 120 t/km 2 /month. This means the values exceed the standard around 3 and 13 times. The Neutron Activation Analysis (NAA) of cement dust showed a percentage of 27.5% ± 1.6 of calcium. By the presence of humidity calcium silicate occurs, which immediately dries and becomes a hard salt crust. Therefore in the regions near by the factory cement dust formed this kind of salt coat on the surface of the leaves. (Authors)

Ontario Hydro looks at security

Green, B.J.; Kee, B.

1995-01-01

Ontario Hydro operates 20 CANDU reactors on three different sites. Since 1984, a review of security arrangements on all the sites has taken place on a five-yearly basis. The review process for 1995 is outlined. The three objectives were as follows: to assess current security threats and risks to the stations; to assess the adequacy of the existing programme to protect against current threats; by comparing the security programme against those of comparable entities to establish benchmarks for good practice as a basis for improvements at Ontario Hydro. Valuable insights gained through the review are listed. These could be useful to other utilities. (UK)

Feimster, E.L.

1997-12-01

Radioactivity surrounding the Point Beach Nuclear Power Plant was measured using aerial radiological surveying techniques. The purpose of this survey was to document exposure rates and identify radiation sources within the survey area. The surveyed area included a 25-square-mile (65-square-kilometer) area, which encompasses the plant site. Data were acquired using an airborne detection system that employed sodium iodide, thallium-activated detectors. Exposure rates at 1 meter above ground level were computed from these data and plotted on a U.S. Geological Survey topographic map of the survey area. Several ground-based exposure-rate measurements were made for comparison with the aerial survey results. Exposure rates in areas surrounding the plant site varied (a) from 10-14 microroentgens per hour (μR/h) in cultivated fields, (b) from 8-10 μR/h in adjacent areas and along roadways, and (c) below 6 μR/h over waterways and wetland areas. Man-made radiation (102-202 μR/h) was found at the plant site; cobalt-60 was the primary source of activity found at the Point Beach site. No other detectable sources of man-made radioactivity were found. The exposure rates measured during this survey agreed well with those measured during the 1970 survey even though the survey methodology and parameters were significantly different

Phoenix, K.A.

1997-04-01

An aerial radiological survey was conducted from May 17--22, 1994, over a 36 square mile (93 square kilometer) area centered on the Fernald Environmental Management Project located in Fernald, Ohio. The purpose of the survey was to detect anomalous gamma radiation in the environment surrounding the plant. The survey was conducted at a nominal altitude of 150 feet (46 meters) with a line spacing of 250 feet (76 meters). A contour map of the terrestrial gamma exposure rate extrapolated to 1 meter (3.3 feet) above ground was prepared and overlaid on an aerial photograph of the area. Analysis of the data for man made sources showed five sites within the boundaries of the Fernald Environmental Management Project having elevated readings. The exposure rates outside the plant boundary were typical of naturally occurring background radiation. Soil samples and pressurized ion chamber measurements were obtained at four locations within the survey boundaries to supplement the aerial data. It was concluded that although the radionuclides identified in the high-exposure-rate areas are naturally occurring, the levels encountered are greatly enhanced due to industrial activities at the plant

Solar and the future of Ontario's electricity supply

International Nuclear Information System (INIS)

McMonagle, R.

2005-01-01

The potential contribution of solar energy to Ontario's electricity supply was evaluated in this PowerPoint presentation. Only 3.5 per cent of Canada's photovoltaic (PV) systems are connected to the electricity grid. However, 47 per cent of all homes in Ontario have the potential to install 3 kW PV arrays, and the solar industry has the potential to achieve growth rates of between 50 to 75 per cent, with medium term sustainable growth estimated at 30 to 40 per cent annually. The benefits of grid-connected solar energy include employment and wealth creation in Ontario; reductions in peak demand; and improved grid efficiency. It was noted that the price of solar PV is declining. Various market niches for solar energy technologies were outlined, and the targeting of early adopters was recommended as a first market for PV growth. An overview of the value of PV build-ups in California was presented, as well details of international tariffs and rates. A 10 year program leading to the installation of 15,000 PV systems or 40 MWp of installed capacity in Ontario by 2015 was outlined, as well as a plan for solar financing. It was concluded that priming the market now will mean that solar will be prepared to contribute to Ontario's supply during the 2015-2025 period, when its price will be competitive. refs., tabs., figs

Observations and modeling results were used to examine spatial scales and transport patterns of ozone pollution in the Ontario-New York region. - We investigated the effects of transboundary pollution between Ontario and New York using both observations and modeling results. Analysis of the spatial scales associated with ozone pollution revealed the regional and international character of this pollutant. A back-trajectory-clustering methodology was used to evaluate the potential for transboundary pollution trading and to identify potential pollution source regions for two sites: CN tower in Toronto and the World Trade Center in New York City. Transboundary pollution transport was evident at both locations. The major pollution source areas for the period examined were the Ohio River Valley and Midwest. Finally, we examined the transboundary impact of emission reductions through photochemical models. We found that emissions from both New York and Ontario were transported across the border and that reductions in predicted O 3 levels can be substantial when emissions on both sides of the border are reduced

An aerial radiological survey was conducted from July 18 through July 25, 1988, over a 41-square-kilometer (16-square-mile) area surrounding the Babcock and Wilcox nuclear facilities located near Lynchburg, Virginia. The survey was conducted at a nominal altitude of 61 meters (200 feet) with line spacings of 91 meters (300 feet). A contour map of the terrestrial gamma exposure rate extrapolated to 1 meter above ground level (AGL) was prepared and overlaid on an aerial photograph. The terrestrial exposure rates varied from 8 to 12 microroentgens per hour (μR/h). A search of the data for man-made radiation sources revealed the presence of three areas of high count rates in the survey area. Spectra accumulated over the main plant showed the presence of cobalt-60 ( 60 Co) and cesium-137 ( 137 Cs). A second area near the main plant indicated the presence of uranium-235 ( 235 U). Protactinium-234m ( 234m Pa) and 60 Co Were detected over a building to the east of the main plant. Soil samples and pressurized ion chamber measurements were obtained at four locations within the survey boundaries in support of the aerial data

An aerial radiological survey was conducted over the South Texas Project Electric Generating Station (STPEGS) near Bay City, Texas, during the period 25 March to 4 April 1988. The purpose of the 259-square-kilometer (100-square-mile) survey was to document the terrestrial gamma environment of the plant and surrounding area. An exposure rate contour map at 1 meter above ground level (AGL) was constructed from the gamma data and overlaid on an aerial photograph and map of the area. Exposure rates were observed up to 10μR/h over land. No areas of enhanced exposure rates were observed. Ground-based exposure rate measurements and soil samples were obtained to support the aerial data. Oblique aerial photographs of the plant were also acquired during the survey. 9 refs., 4 figs., 1 tab

Atmospheric fluoride levels in some Ontario peach orchards

Drowley, W B; Rayner, A C; Jephcott, C M

1963-10-01

As a result of suture injury to peaches, a survey was taken to determine monthly atmospheric fluoride levels in the soft fruit-growing area of the Niagara Peninsula of Ontario. Although the injury was confined to a few orchards, it was found necessary to locate stations for fluoride sampling over a wide area. The limed-paper candle method was used for fluoride collection. Unwashed and washed peach leaves were analyzed for fluoride content. Fluoride was separated from all samples by the Willard-Winter distillation procedure and estimated colorimetrically. It was found that a general background level of atmospheric fluoride existed in the whole surveyed area and that the levels were highest in and near the area of peach injury. The fluoride content of peach leaves was also highest in this area. The coincidence of high fluoride levels and suture injury to peaches suggests that atmospheric fluoride was the causal agent. When lime sprays were applied to peach trees in the damaged area, a reduction in the incidence of suture injury was observed.

During the five year period 1985 to 1990, Ontario Hydro conducted a major study with the objective to reduce the cost and construction duration for future nuclear generating facilities in Ontario. This paper reports on the study called Major Projects: Schedule and Cost Reduction Study (SCRS). Ontario Hydro is a public utility with the responsibility for meeting electricity need for the province of Ontario with a population of 9.6 million. In order to adequately address future electricity needs, Ontario Hydro has developed and submitted a demand/supply plan which covers the next 25 years. The SCRS for major projects contributed to this demand/supply plan

Transforming Ontario's Power Generation Company

Manley, J.; Epp, J.; Godsoe, P.C.

2004-01-01

The OPG Review Committee was formed by the Ontario Ministry of Energy to provide recommendations and advice on the future role of Ontario Power Generation Inc. (OPG) in the electricity sector. This report describes the future structure of OPG with reference to the appropriate corporate governance and senior management structure. It also discusses the potential refurbishing of the Pickering A nuclear generating Units 1, 2 and 3. The electricity system in Ontario is becoming increasingly fragile. The province relies heavily on electricity imports and the transmission system is being pushed to near capacity. Three nuclear generating units are out of service. The problems can be attributed to the fact that the electricity sector has been subjected to unpredictable policy changes for more than a decade, and that the largest electricity generator (OPG) has not been well governed. OPG has had frequent senior management change, accountability has been weak, and cost overruns have delayed the return to service of the Pickering nuclear power Unit 4. It was noted that the generating assets owned and operated by OPG are capable of providing more than 70 per cent of Ontario's electricity supply. Decisive action is needed now to avoid a potential supply shortage of about 5,000 to 7,000 megawatts by 2007. In its current state, OPG risks becoming a burden on ratepayers. Forty recommendations were presented, some of which suggest that OPG should become a rate-regulated commercial utility focused on running and maintaining its core generating assets. This would require that the government act as a shareholder, and the company operate like a commercial business. It was also emphasized that the market must be allowed to bring in new players. refs., tabs., figs

Aerial radiological survey of the Shoreham Nuclear Power Station and surrounding area Brookhaven, New York

International Nuclear Information System (INIS)

1984-03-01

An aerial radiological survey was performed over the area surrounding the Shoreham Nuclear Power Station during 5 to 9 June 1983. The survey, which covered an area of 338 square kilometers (131 square miles), also encompassed the entire Brookhaven National Laboratory (BNL) facility. The highest radiation exposure rate, over 1 milliroentgen per hour (mR/h), was inferred from data measured directly over the BNL facility. This detected activity was due to the presence of cobalt-58, cobalt-60 and cesium-137, which was consistent with normal BNL operations. With the exception of the BNL facility, the only detected man-made radioactivity was found near a cottage in Moriches, New York and was due to the presence of cobalt-60. For the remainder of the survey area, the inferred radiation exposure rates varied generally from 6 to 12 microroentgens per hour (μR/h). The reported exposure rate values include an estimated cosmic ray contribution of 3.7 μR/h. Ground-based measurements, conducted concurrently with the aerial survey, were compared to the inferred aerial results. Pressurized ionization chamber readings and a group of soil samples were acquired from five locations within the survey area. The exposure rate values obtained from these measurements were consistent with those inferred from the aerial results. 11 references, 12 figures, 3 tables

Full cost accounting for decision making at Ontario Hydro

International Nuclear Information System (INIS)

Plagiannakos, T.

1996-01-01

Ontario Hydro's approach to full cost accounting (FCA) was outlined in response to questions raised earlier, in another forum, regarding Ontario Hydro's views on FCA. FCA was defined as an evaluation framework (as opposed to an accounting system) which tries to account for the internal (private) as well as the external (environment and human health) costs and benefits and integrate them into business decisions. When the external impacts cannot be monetized, qualitative evaluations are used based on the damage costing approach, which Ontario Hydro prefers to the cost of control method recommended by its critics. In general, however, Ontario Hydro is not opposed to FCA in so far as it puts the Utility in a better position to make more informed decisions, improve environmental cost management, avoid future costs, enhance revenue, improve environmental quality, contribute to environmental policy, and contribute to sustainable development. 1 fig

Electricity market price volatility: The case of Ontario

Zareipour, Hamidreza; Bhattacharya, Kankar; Canizares, Claudio A.

2007-01-01

Price volatility analysis has been reported in the literature for most competitive electricity markets around the world. However, no studies have been published yet that quantify price volatility in the Ontario electricity market, which is the focus of the present paper. In this paper, a comparative volatility analysis is conducted for the Ontario market and its neighboring electricity markets. Volatility indices are developed based on historical volatility and price velocity concepts, previously applied to other electricity market prices, and employed in the present work. The analysis is carried out in two scenarios: in the first scenario, the volatility indices are determined for the entire price time series. In the second scenario, the price time series are broken up into 24 time series for each of the 24 h and volatility indices are calculated for each specific hour separately. The volatility indices are also applied to the locational marginal prices of several pricing points in the New England, New York, and PJM electricity markets. The outcomes reveal that price volatility is significantly higher in Ontario than the three studied neighboring electricity markets. Furthermore, comparison of the results of this study with similar findings previously published for 15 other electricity markets demonstrates that the Ontario electricity market is one of the most volatile electricity markets world-wide. This high volatility is argued to be associated with the fact that Ontario is a single-settlement, real-time market

The short-term impact of Ontario's generic pricing reforms.

Directory of Open Access Journals (Sweden)

Michael R Law

Full Text Available Canadians pay amongst the highest generic drug prices in the world. In July 2010, the province of Ontario enacted a policy that halved reimbursement for generic drugs from the public drug plan, and substantially lowered prices for private purchases. We quantified the impact of this policy on overall generic drug expenditures in the province, and projected the impact in other provinces had they mimicked this pricing change.We used quarterly prescription generic drug dispensing data from the IMS-Brogan CompuScript Audit. We used the price per unit in both the pre- and post-policy period and two economics price indexes to estimate the expenditure reduction in Ontario. Further, we used the post-policy Ontario prices to estimate the potential reduction in other provinces.We estimate that total expenditure on generic drugs in Ontario during the second half of 2010 was between $181 and $194 million below what would be expected if prices had remained at pre-policy level. Over half of the reduction in spending was due to savings on just 10 generic ingredients. If other provinces had matched Ontario's prices, their expenditures over during the latter half of 2010 would have been $445 million lower.We found that if Ontario's pricing scheme were adopted nationally, overall spending on generic drugs in Canada would drop at least $1.28 billion annually--a 5% decrease in total prescription drug expenditure. Other provinces should seriously consider both changes to their generic drug prices and the use of more competitive bulk purchasing policies.

Studies on the terrestrial effects of acidic precipitation in Ontario involve determining the effects on soils, crops, forests, lichens, mosses and biogeochemical systems. In the soils program, a baseline study was started in 1980 to establish a reliable and uniform data base for soils across the province, in order to identify future trends. Soil sensitivity criteria are being derived for mapping purposes. Starting in 1982, a complex, sophisticated mobile rain exclusion canopy system was constructed outdoors for controlled acid rain studies to determine the dose-response relationships of field crops. In response to numerous complaints a program was designed to determine the role that acidic precipitation is playing in the decline of sugar maple trees in Ontario. At 8 sites, tree conditions were noted, samples of foliage, bark, roots and soil were collected for chemical analysis, and increment cores and discs (from felled trees) were taken for radial growth patterns. Results from this study indicated that acidic precipitation was an additional stress to insect outbreaks and spring droughts. Intensive surveys have been conducted in selected areas in Ontario to identify the current viability and distribution of common denominator lichens and mosses. Biogeochemical studies are being conducted at four watersheds in Ontario. The different watersheds are located in progressively decreasing atmospheric deposition loadings from east to west across the province. The studies are attempting to document the role of contrasting terrestrial ecosystems in the process of lake acidification by atmospheric deposition. 9 references.

A serological study was undertaken to determine whether dogs in Ontario are being exposed to Borrelia burgdorferi, the etiological agent of Lyme disease. This study consisted of a survey of randomly selected dogs and testing of diagnostic submissions from candidate Lyme disease cases. The survey of 1,095 dogs, bled between January 1988 and August 1989, revealed a total of 65 (5.9%) enzyme-linked immunosorbent assay (ELISA) reactors, of which 22 had immuno-fluorescent antibody assay (IFA) titers ≥1:32. All but one of the IFA-positive and 10 of the ELISA-positive, IFA-negative sera were further tested by western blot. Eight western blot positive and three equivocal reactors were obtained. Three of the eight confirmed reactors had visited areas known to be endemic for Lyme disease, leaving five reactors that might have been infected in previously undocumented areas for B. burgdorferi activity in Ontario. Diagnostic submissions of sera from 223 dogs were received between August 1987 and February 1992. Test results revealed 21 (9.4%) IFA reactors, of which only six had significant titers (≥1:256) and were reactive by an immunodot Borrelia test. All six dogs had travelled to known Lyme endemic areas. Based on results obtained from this study, it seems likely that the agent of Lyme disease is not widespread in Ontario. PMID:17424284

Verma, Dave K; Sahai, Dru; Kurtz, Lawrence A; Finkelstein, Murray M

2004-05-01

Current occupational exposures to man-made mineral fibers (MMMF), including refractory ceramic fibers (RCF), were measured as part of an exposure assessment program for an epidemiological study pertaining to cancer and mortality patterns of Ontario construction workers. The assessments were carried out at commercial and residential sites. A total of 130 MMMF samples (104 personal and 26 area) was collected and included 21 RCF (16 personal and 5 area). The samples were analyzed by the World Health Organization method in which both respirable and nonrespirable airborne fibers are counted. The results show that Ontario construction workers' full-shift exposure to MMMF (excluding RCF) is generally lower than the American Conference of Governmental Industrial Hygienists' (ACGIH) recommended threshold limit value-time-weighted average (TLV-TWA) of 1 fibers/cc and thus should not present any significant hazard. However, approximately 40% of the occupational exposures to RCF are higher than ACGIH's TLV-TWA of 0.2 fibers/cc and present a significant potential hazard. Workers generally wore adequate approved respiratory protection, especially while performing particularly dusty tasks such as blowing, spraying, and cutting, so the actual exposure received by workers was lower than the reported values. Adequate control measures such as ventilation and respiratory protection should always be used when work involves RCF.

Seven steps to an energy efficient Ontario

International Nuclear Information System (INIS)

2003-01-01

The future of the electricity market in Ontario is examined in light of the recent debate concerning deregulation. This report focuses on measures that would have to be taken to ensure that there will be sufficient electricity available to serve the needs of Ontario. Increasing supply, or decreasing demand are discussed as the obvious answers to the problem at hand. The report concludes that: (1) mechanisms to encourage Demand Side Management and Demand Response have all but disappeared since the opening of the competitive electricity market in Ontario, (2) the current market structure does nothing to stimulate increased supply, nor does it encourage measures to reduce demand; as such, the result is an unsustainable situation. The report further concludes that Demand Side Management and Demand Response programs are essential components of the success of Ontario's evolving electricity market, and recommends programs that are designed and implemented in a manner that dovetail with parallel policies dealing with supply challenges. Seven essential elements of such a policy are discussed. These are: (1) vision and a clear set of goals for demand side management; (2) appropriate market drivers, principles and pricing incentives; (3) a central co-ordinating authority for managing demand side management; (4) appropriate implementation agents to manage programs and processes; (5) incentives to motivate change; (6) widespread education of the market; and (7) appropriate tactics to enable demand side management in sectors

An aerial radiological survey of the Enrico Fermi Atomic Power Plant and surrounding area, Newport, Michigan

International Nuclear Information System (INIS)

1986-05-01

An aerial radiological survey was performed over the area surrounding the Enrico Fermi Atomic Power Plant during the period 27 to 30 May 1986. The survey covered a 64-square-kilometer (25-square-mile) area around the plant. The deteted radiation was due to the presence of varying concentrations of naturally-occurring radioactive materials. Radionuclides of the uranium and thorium decay chains and radioactive potassium were found. For the majority of the survey area, the inferred radiation exposure rate levels varied between 10 and 12 microroentgens per hour (μR/h). The reported exposure rate values included an estimated cosmic ray contribution of 3.7 μR/h. Ground-based measurements, conducted concurrently with the aerial survey, were compared to the inferred aerial results. Pressurized ionization chamber readings and a group of soil samples were acquired at five locations within the survey area. The exposure rate values obtained from these ground-based measurements were in good agreement with the corresponding inferred aerial values. No evidence was found of any radioactive contamination which might have occurred as a result of plant operations. This conclusion was supported by the results of the soil samples analyses and the comparison of the current survey data with those obtained in September 1970. 7 refs., 5 figs., 1 tab

Ontario Business Survey Program on energy : impacts of power failure on Ontario businesses

International Nuclear Information System (INIS)

2003-01-01

The Ontario Chamber of Commerce conducted a survey for its members between August 19-23, 2003 to determine the impact of the massive power failure that took place on August 14, 2003. This paper presents the results of the survey which are based on a total of 929 respondents across Ontario. The primary businesses that participated in the survey were: manufacturing, service, technology, commercial, retail, automotive, steel, forestry, and resource businesses. 78 per cent of the respondents replied that the power disruption had a negative impact on their business. 48 per cent of the respondents were without power for 11-24 hours. 65 per cent of the businesses did not have a blackout contingency plan in place, but 63 per cent responded that they will likely develop a plan for future power failures. The survey also asked business members how they would rate the federal, provincial and municipal government's response to the emergency. The participants ranked the top 3 actions that governments can take to prevent future outages as follows: (1) review possible changes to the interconnected grid system, (2) ensure sufficient supply within Ontario, and (3) invest in alternative forms of energy such as solar and wind power. Other recommendations were to implement a sliding scale of energy pricing to reflect the true cost of energy. It was suggested that tax incentives should be offered to encourage energy conservation and the use of alternative energy sources. 2.6 per cent of the respondents suggested that excess energy should not be sold to neighbouring jurisdictions. 1 tab., 6 figs

Issues concerning the social acceptance of wind energy are major challenges for policy-makers, communities and wind developers. They also impact the legitimacy of societal decisions to pursue wind energy. Here we set out to identify and assess the factors that lead to wind energy disputes in Ontario, Canada, a region of the world that has experienced a rapid increase in the development of wind energy. Based on our expertise as a group comprising social scientists, a community representative and a wind industry advocate engaged in the Ontario wind energy situation, we explore and suggest recommendations based on four key factors: socially mediated health concerns, the distribution of financial benefits, lack of meaningful engagement and failure to treat landscape concerns seriously. Ontario's recent change from a feed-in-tariff-based renewable electricity procurement process to a competitive bid process, albeit with more attention to community engagement, will only partially address these concerns.

Ontario hydro waste storage concepts and facilities

Carter, T.J.; Mentes, G.A.

1976-01-01

Ontario Hydro presently operates 2,200 MWe of CANDU heavy water reactors with a further 11,000 MWe under design or construction. The annual quantities of low and medium level solid wastes expected to be produced at these stations are tabulated. In order to manage these wastes, Ontario Hydro established a Radioactive Waste Operations Site within the Bruce Nuclear Power Development located on Lake Huron about 250 km northwest of Toronto. The Waste Operations Site includes a 19-acre Storage Site plus a Radioactive Waste Volume Reduction Facility consisting of an incinerator and waste compactor. Ontario has in use or under construction both in-ground and above-ground storage facilities. In-ground facilities have been used for a number of years while the above-ground facilities are a more recent approach. Water, either in the form of precipitation, surface or subsurface water, presents the greatest concern with respect to confinement integrity and safe waste handling and storage operations

To overview the newly developed Psychosocial Health Care for Cancer Patients and Their Families: A Framework to Guide Practice in Ontario and Guideline Recommendations in the context of Canadian psychosocial oncology care and propose strategies for guideline uptake and implementation. Recommendations from the 2008 Institute of Medicine standard Cancer Care for the Whole Patient: Meeting Psychosocial Health Needs were adapted into the Ontario Psychosocial Oncology (PSO) Framework. Existing practice guidelines developed by the Canadian Partnership against Cancer and Cancer Care Ontario and standards developed by the Canadian Association of Psychosocial Oncology are supporting resources for adopting a quality improvement (QI) approach to the implementation of the framework in Ontario. The developed PSO Framework, including 31 specific actionable recommendations, is intended to improve the quality of comprehensive cancer care at both the provider and system levels. Important QI change management processes are described as Educate - raising awareness among medical teams of the significance of psychosocial needs of patients, Evidence - developing a research evidence base for patient care benefits from psychosocial interventions, and Electronics - using technology to collect patient reported outcomes of both physical and emotional symptoms. The Ontario PSO Framework is unique and valuable in providing actionable recommendations that can be implemented through QI processes. Overall, the result will be improved psychosocial health care for the cancer population. Copyright © 2012 John Wiley & Sons, Ltd.

The safety of Ontario's nuclear power reactors. A scientific and technical review. Ontario Hydro Submission to the Ontario Nuclear Safety Review

International Nuclear Information System (INIS)

1987-01-01

Ontario Hydro is responsible for the safety of its nuclear stations: safety analysis, design and construction, training of operators, operating practices, and maintenance procedures. The utility must demonstrate to the regulatory body and the public that it is capable of operating nuclear stations safely. the dedicated attention of management and workers alike has been given to the achievement of an excellent safety record. Safety begins with well understood corporate goals, objectives and policies, and the clear assignment of responsibilities to well-trained, competent people who have the relevant experience and the right information and equipment. A prime cause of both the Chernobyl and the Three Mile Island accidents was a breakdown in operational procedures and human factors. On the contrary, the pressure tube failure at Pickering unit 2 in 1983 was understood almost immediately by the operators, who took the correct steps to shut down the reactor. This success is related to well-designed control room information systems and good understanding of fundamentals by the operators. Increasingly, in the design of nuclear plant control and instrumentation systems and in training in Ontario Hydro, the well-being, capabilities and limitations of humans are being taken into account. This report describes the series of barriers between the radioactive material in the fuel and the series of barriers between the radioactive material in the fuel and the environment, and the stringent quality control and technical measures taken to make the likelihood of malfunctions very small. Defence in depth protection for the public is a feature of all Ontario Hydro nuclear stations. As safety-related systems are updated in new stations, improvements are in some cases being backfitted to older stations

Climate change impacts: an Ontario perspective

International Nuclear Information System (INIS)

Mortsch, L.

1995-11-01

Significant changes in the climate system which are likely to affect biophysical, social and economic systems in various ways, were discussed. Trends in greenhouse gas levels show that during the 20. century, human activity has changed the make-up of the atmosphere and its greenhouse effect properties. A pilot study on the impacts of climate change identified changes in the water regime such as declines in net basin supply, lake levels and outflows, as important concerns. These changes would have impacts on water quality, wetlands, municipal water supply, hydroelectric power generation, commercial shipping, tourism and recreation, and to a lesser extent, on food productions. Climate impact assessments suggest that world conditions will change significantly as a result. Those with less resources are likely to be most affected by climate change, and the impacts on other regions of the world will be more significant to Ontario than the direct impacts on Ontario itself. In an effort to keep pace with global changes, Ontario will have to limit emissions, conduct research in innovative technology and develop greater awareness of the risk of climate change. refs., tabs., figs

Why we must move quickly to open Ontario's power market

International Nuclear Information System (INIS)

Brooks, J.

2001-01-01

This paper presented issues regarding the reform in Ontario's electricity sector and why the Independent Power Producer's Society of Ontario (IPPSO) believes it is necessary to open the electricity market in the province as soon as possible. The 400 members of IPPSO include developers, suppliers, consultants and various professionals working in the fields of co-generation, small hydro, biomass, wind energy and other technologies with a total generating capacity of about 1600 MW in Ontario. The government of Ontario recently announced four principles for implementing competition in the electricity sector which were protecting the consumers and offering choice, creating a strong business climate, protecting the environment, and supporting innovation and alternative energy development. This paper described the possible indicators of success in implementing these four principles and provided a historical perspective on the motivation for bringing in competition

Chang'e-3 (CE-3) landed on the Mare Imbrium basin in the east part of Sinus Iridum (19.51°W, 44.12°N), which was China's first soft landing on the Moon and it started collecting data on the lunar surface environment. To better understand the environment of this region, this paper utilizes the available high-resolution topography data, image data and geological data to carry out a detailed analysis and research on the area surrounding the landing site (Sinus Iridum and 45 km×70 km of the landing area) as well as on the topography, landform, geology and lunar dust of the area surrounding the landing site. A general topographic analysis of the surrounding area is based on a digital elevation model and digital elevation model data acquired by Chang'e-2 that have high resolution; the geology analysis is based on lunar geological data published by USGS; the study on topographic factors and distribution of craters and rocks in the surrounding area covering 4 km×4 km or even smaller is based on images from the CE-3 landing camera and images from the topographic camera; an analysis is done of the effect of the CE-3 engine plume on the lunar surface by comparing images before and after the landing using data from the landing camera. A comprehensive analysis of the results shows that the landing site and its surrounding area are identified as typical lunar mare with flat topography. They are suitable for maneuvers by the rover, and are rich in geological phenomena and scientific targets, making it an ideal site for exploration.

Weidel, Brian C.; Walsh, Maureen; Connerton, Michael J.

2014-01-01

The 2013 benthic fish assessment was delayed and shortened as a result of the U.S. Government shutdown, however the assessment collected 51 of the 62 planned bottom trawls. Over the past 34 years, Slimy Sculpin abundance in Lake Ontario has fluctuated, but ultimately decreased by two orders of magnitude, with a substantial decline occurring in the past 10 years. The 2013 Slimy Sculpin mean bottom trawl catch density (0.001 ind.·m-2, s.d.= 0.0017, n = 52) and mean biomass density (0.015 g·m-2 , s.d.= 0.038, n = 52) were the lowest recorded in the 27 years of sampling using the original bottom trawl design. From 2011-2013, the Slimy Sculpin density and biomass density has decreased by approximately 50% each year. Spring bottom trawl catches illustrate Slimy Sculpin and Round Goby Neogobius melanostoma winter habitat overlaps for as much as 7 months out of a year, providing opportunities for competition and predation. Invasive species, salmonid piscivory, and declines in native benthic invertebrates are likely all important drivers of Slimy Sculpin population dynamics in Lake Ontario. Deepwater Sculpin Myoxocephalus thompsonii, considered rare or absent from Lake Ontario for 30 years, have generally increased over the past eight years. For the first time since they were caught in this assessment, Deepwater Sculpin density and biomass density estimates declined from the previous year. The 2013 abundance and density estimates for trawls covering the standard depths from 60m to 150m was 0.0001 fish per square meter and 0.0028 grams per square meter. In 2013, very few small (recruitment. Nonnative Round Gobies were first detected in the USGS/NYSDEC Lake Ontario spring Alewife assessment in 2002. Since that assessment, observations indicate their population has expanded and they are now found along the entire south shore of Lake Ontario, with the highest densities in U.S. waters just east of the Niagara River confluence. In the 2013 spring-based assessment, both the

Ontario demand response scenarios

International Nuclear Information System (INIS)

Rowlands, I.H.

2005-09-01

Strategies for demand management in Ontario were examined via 2 scenarios for a commercial/institutional building with a normal summertime peak load of 300 kW between 14:00 and 18:00 during a period of high electricity demand and high electricity prices. The first scenario involved the deployment of a 150 kW on-site generator fuelled by either diesel or natural gas. The second scenario involved curtailing load by 60 kW during the same periods. Costs and benefits of both scenarios were evaluated for 3 groups: consumers, system operators and society. Benefits included electricity cost savings, deferred transmission capacity development, lower system prices for electricity, as well as environmental changes, economic development, and a greater sense of corporate social responsibility. It was noted that while significant benefits were observed for all 3 groups, they were not substantial enough to encourage action, as the savings arising from deferred generation capacity development do not accrue to individual players. The largest potential benefit was identified as lower prices, spread across all users of electricity in Ontario. It was recommended that representative bodies cooperate so that the system-wide benefits can be reaped. It was noted that if 10 municipal utilities were able to have 250 commercial or institutional customers engaged in distributed response, then a total peak demand reduction of 375 MW could be achieved, representing more than 25 per cent of Ontario's target for energy conservation. It was concluded that demand response often involves the investment of capital and new on-site procedures, which may affect reactions to various incentives. 78 refs., 10 tabs., 5 figs

Lead isotope identification of sources of galena from some prehistoric Indian sites in Ontario, Canada

International Nuclear Information System (INIS)

Farquhar, R.M.; Fletcher, I.R.

1980-01-01

Lead isotopic compositions of 12 galenas from five late Archaic-initial Woodland grave and habitation sites in southern Ontario have made it possible to determine the most likely source areas for the galenas. For one of the oldest sites (Finlan), the most likely source is in the southwestern Upper Mississippi Valley (Wisconsin-Illinois-Iowa) mineral district. The seven Finlan galenas exhibit a range of isotopic ratios; three of the largest specimens have substantial isotopic variations (up to 1.8% in the ratio of lead-207 to lead-206) on a scale of a few centimeters. This suggests that the lead isotopic zoning ascribed to the Upper Mississippi Valley area is not sufficiently well defined to enable us to determine if all the Finlan samples were derived from a single mineral deposit. Galenas from the other sites (Constance Bay, Hind, Bruce Boyd, and Picton) most probably originated in the southeastern Ontario-northwestern New York area. Isotopic differences among the Constance Bay, Hind, and Bruce Boyd galenas, on the one hand, and the Picton galena, on the other, suggest that at least two distinct sources in that region were exploited

2004-01-01

This paper discusses the business strategy needed to spark investment in Ontario's power generation industry. It examines the process of decision making and investing in an uncertain environment. The paper suggests that any strategy based on one view of the future courts trouble and that strategic flexibility can prepare for what cannot be predicted. Finally the paper suggests that Ontario needs to create a stable policy and regulatory environment that allows investors to fulfill reasonable expectations and investors need to place bets that provide the flexibility to respond quickly to changing market conditions

The effect of Ontario's transmission system policies on cogeneration projects

International Nuclear Information System (INIS)

Carr, J.

1999-01-01

The impact that the establishment of transmission tariffs would have on the viability of cogeneration projects in Ontario was discussed. The proposal to establish such tariffs on the basis of a 'postage stamp' rate would ensure that all electricity users have access to electricity at the same price. However, this would unfairly penalize short-haul transmission transactions and would possibly result in the inappropriate location of new generation facilities. Electricity users would ultimately be burdened with these inefficiencies. This presentation also discussed another public policy which proposes to determine what parts of the electricity system should have their costs recovered at postage stamp rates. The costs would include not only transmission charges but also distribution and generation costs. The restructuring of Ontario Hydro into the Ontario Power Generation Company (OPGC) and the Ontario Hydro Services Company (OHSC) and its impact on the cogeneration projects was also discussed

Apparent changes in the temperature patterns in recent years brought many challenges to the province of Ontario, Canada. As the need for adapting to climate change challenges increases, the development of reliable climate projections becomes a crucial task. In this study, a regional climate modeling system, Providing Regional Climates for Impacts Studies (PRECIS), is used to simulate the temperature patterns in Ontario. Three PRECIS runs with a resolution of 25 km × 25 km are carried out to simulate the present (1961-1990) temperature variations. There is a good match between the simulated and observed data, which validates the performance of PRECIS in reproducing temperature changes in Ontario. Future changes of daily maximum, mean, and minimum temperatures during the period 2071-2100 are then projected under the IPCC SRES A2 and B2 emission scenarios using PRECIS. Spatial variations of annual mean temperature, mean diurnal range, and temperature seasonality are generated. Furthermore, heat waves defined based on the exceedance of local climatology and their temporal and spatial characteristics are analyzed. The results indicate that the highest temperature and the most intensive heat waves are most likely to occur at the Toronto-Windsor corridor in Southern Ontario. The Northern Ontario, in spite of the relatively low projected temperature, would be under the risk of long-lasting heat waves, and thus needs effective measures to enhance its climate resilience in the future. This study can assist the decision makers in better understanding the future temperature changes in Ontario and provide decision support for mitigating heat-related loss.

Wood-fired electricity generation in Eastern Ontario

Energy Technology Data Exchange (ETDEWEB)

1978-07-01

The feasibility of using large areas of currently unproductive rural land in Ontario for poplar plantations which would supply fuel for wood-fired power plants was examined. Information is included on the productive potential of such poplar plantations, the technology of wood-fired steam-electric plants, costs of wood and water supplies, location of plants, cost of power generation, and socio-economic effects. It was concluded that approximately 1.7 million acres of unused land are available which could produce 7 to 10 million tons of wood fuel per year which in turn could be converted to 1600 MW/yr over the next 10 yr. No adverse environmental effects are expected. The project would economically benefit an area of high unemployment. It is recommended that a more detailed feasibility study be undertaken to establish land availability and acquisition, cost of power generation in wood-fired plants, and the economic impact of such a project.

Staff report on Ontario gas distributor service quality regulation

Energy Technology Data Exchange (ETDEWEB)

NONE

2005-07-29

This report provides the basis for consultation regarding a framework for building principles and minimum standards regarding service quality measures for gas distributors. It begins with a general overview of current concerns expressed by Ontario natural gas consumers regarding service quality. Customer complaints logged with the Ontario Energy Board between 2003 and 2004 include common issues such as slow telephone response time, failure to obtain regular meter reads, inaccurate billing, long payment processing times, long reconnection times, long new connection times, and slow response to emergencies. This report also presents the historical experience in Ontario's energy sector regarding performance monitoring of services within an incentive based rate making framework for electricity and gas distributors. The Ontario Energy Board's Natural Gas Forum report reveals that a service quality framework would ensure that cost saving initiatives are not implemented at the expense of customer service or safe operation of the distribution system. Although the Board intends to implement a service quality framework, it will not include direct financial incentives. Rather, it will monitor service quality performance and utilities will be subject to a compliance process. A brief summary was also included of service quality regulations in the electricity sector and in other jurisdictions such as Australia, the United Kingdom, Pennsylvania, and Alberta. A list of issues that remain to be addressed before implementing a framework in Ontario was then presented. 2 appendices.

Ontario pharmacists' crisis over Bill 16: A missed opportunity?

Science.gov (United States)

Rosenthal, Meagen; Austin, Zubin; Tsuyuki, Ross T

2012-01-01

In 2010, the Ontario government brought forward Bill 16, which, among other things, removed pharmacists' professional allowances. While many would disagree with this unilateral action by the Ontario government, it also could have served as a crisis for change towards patient-centred care. We sought to examine the response of the pharmacy profession in Ontario to this crisis as it relates to the vision outlined in the Blueprint for Pharmacy. We systematically examined publicly available responses to Schedule 5 of Ontario's Bill 16 during the period from April to June 16, 2010. A rapid textual analysis of the data using tag or word clouds and a qualitative content analysis were performed on all of the data collected. The rapid textual analysis revealed that the most frequently used terms were "pharmacist," "pharmacy" and "professional allowances"; the least used were "layoffs," "service cuts" and "patient care." Content analysis revealed 4 themes: the desire to maintain the status quo of practice, a focus on the business of pharmacy, pharmacy stakeholders' perceptions of government's attitude towards the profession and changes to patient services. It is notable that patient care was almost completely absent from the discussion, a reflection that our profession has not embraced patient-centred care. This also represents a missed opportunity - a crisis that could have been used to move the profession towards the Blueprint's vision. We thought that the Blueprint had already achieved this consensus, but the Ontario experience has shown that this may not be the case.

Analysis of the potential for wind energy production in northwestern Ontario

Energy Technology Data Exchange (ETDEWEB)

Brown, C K; Warne, D F

1975-11-01

A study of the feasibility of generating electric power from wind generators at remote sites in Northwestern Ontario has been carried out on behalf of the Ontario Ministry of Energy, with project management from Ontario Hydro. The work included (1) a survey of commercially available wind driven electric plant, both currently available and planned for production, (2) an analysis of existing wind data and preparation of an isovent map for Ontario showing annual mean wind speeds, (3) the selection of suitable sites for a demonstration unit and a prototype system, (4) the matching of available plant to the wind regimes to predict annual energy production, and (5) a systems analysis of pure diesel, hybrid wind/diesel and pure wind electric plants to determine the cost of power from the various alternatives.

Gas marketing strategies for Ontario producers

Energy Technology Data Exchange (ETDEWEB)

Walsh, P.R. [Energy Objective Ltd., London, ON (Canada)

2000-07-01

Activity in natural gas exploration and production in the province of Ontario has recently increased due to higher natural gas prices. This paper discussed the issue of how the gas from the new reserves should be marketed. A review of historical pricing and consumption patterns was also presented to better identify how prices of natural gas are determined in Ontario and to forecast the future demand for natural gas. The first trend of interest is the increased use of natural gas in generating electricity to meet cooling needs in the summer months. The second trend is the increase in gas consumption by the industrial sector resulting from increases in process load. Several marketing options are available to Ontario natural gas producers. They can market their gas to third parties at various trading points in the province or they can market it directly to Union Gas Limited, the local gas utility. This paper briefly described how a gas supply contract works with the union, how gas marketing agreement is conducted with a gas marketer, and how a gas marketing arrangement works with a consultant. Some of the pitfalls of marketing natural gas were also described and some recommended some strategies for selling natural gas in the future were presented. 7 figs.

Purpose: The Radiation Incident and Safety Committee (RISC), established and supported by Cancer Care Ontario (CCO), is responsible for advising the Provincial Head of the Radiation Treatment program on matters relating to provincial reporting of radiation incidents with the goal of improved risk mitigation. Methods: The committee is made up of Radiation Incident Leads (RILs) with representation from each of the 14 radiation medicine programs in the province. RISC routinely meets to review recent critical incidents and to discuss provincial reporting processes and future directions of the committee. Regular face to face meetings have provided an excellent venue for sharing incident learning practices. A summary of the incident learning practices across Ontario has been compiled. Results: Almost all programs in Ontario employ an incident learning committee to review incidents and identify corrective actions or process improvements. Tools used for incident reporting include: paper based reporting, a number of different commercial products and software solutions developed in-house. A wide range of classification schema (data taxonomies) are employed, although most have been influenced by national guidance documents. The majority of clinics perform root cause analyses but utilized methodologies vary significantly. Conclusions: Most programs in Ontario employ a committee approach to incident learning. However, the reporting tools and taxonomies in use vary greatly which represents a significant challenge to provincial reporting. RISC is preparing to adopt the National System for Incident Reporting – Radiation Therapy (NSIR-RT) which will standardize incident reporting and facilitate data analyses aimed at identifying targeted improvement initiatives.

Global warming: Towards a strategy for Ontario

International Nuclear Information System (INIS)

1990-01-01

A discussion paper is provided as background to a proposed public review of a strategy for Ontario's response to global warming. Global warming arises from the generation of greenhouse gases, which come from the use of fossil fuels, the use of chlorofluorocarbons, and deforestation. Energy policy is the backbone of achieving climate stability since the burning of fossil fuels releases most of the greenhouse gases, mainly carbon dioxide. Canada is, by international standards, a very energy-intensive country and is among the world's largest emitters of carbon dioxide on a per capita basis. Ontario is the largest energy-using province in Canada, and fossil fuels represent over 80% of provincial energy use. A proposed goal for Ontario is to provide leadership in stabilizing atmospheric concentrations of the greenhouse gases, while minimizing the social, economic, and environmental costs in Ontario of adapting to global warming. A proposed first step to address global warming is to achieve reductions in expected emissions of the greenhouse gases, especially carbon dioxide, so that levels by the year 2000 are lower than in 1989. Current policies and regulations helping to reduce the greenhouse effect include some of the current controls on automotive emissions and the adoption by the provincial electric utility of targets to reduce electricity demand. New initiatives include establishment of minimum energy efficiency standards and reduction of peak-day electricity use. Action steps for future consideration are detailed in the categories of greenhouse gas emissions reductions, carbon dioxide absorption, and research and analysis into global warming

Carleton, T.J.

1993-12-31

This study explored changes in understory species composition and floristic diversity in eastern white pine and red pine stands in Ontario in relation to differences in site condition and stand age. It surveyed 170 natural, fire-origin stands containing at least a 10% component of red pine and white pine basal area throughout the Canadian Shield in Ontario during 1991 and 1992. The stands had not been previously logged and ranged in age from 50-300 years. Sampling was conducted using plots of fixed area. Within these plots, subplots were sampled to capture the variety of vegetation that occurred at different scales. Stand-level data were also recorded outside the fixed area plots. Detailed site data were also collected, including information on soils, topography, coarse woody debris (both standing and fallen), and the nature of the forest floor substrates.

1993-10-01

An aerial radiological survey was conducted over the Vermont Yankee Nuclear Power Station in Vernon, Vermont, during the period August 7 through August 17, 1989. The survey was conducted at an altitude of 300 feet (91 meters) over a 65-square-mile (168-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Vermont Yankee Power Station and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 6 and 10 microroentgens per hour (μR/h) and were attributed to naturally occurring uranium, thorium, and radioactive potassium gamma emitters. The aerial data were compared to ground-based open-quotes benchmarkclose quotes exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system

The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 6 and 10 microroentgens per hour (μR/h) and were attributed to naturally-occurring uranium, thorium, and radioactive potassium gamma emitters. The aerial data were compared to ground-based ''benchmark'' exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system

Sources of aminomethylphosphonic acid (AMPA) in urban and rural catchments in Ontario, Canada: Glyphosate or phosphonates in wastewater?

Struger, J.; Van Stempvoort, D.R.; Brown, S.J.

2015-01-01

Correlation analysis suggests that occurrences of AMPA in streams of southern Ontario are linked mainly to glyphosate in both urban and rural settings, rather than to wastewater sources, as some previous studies have suggested. For this analysis the artificial sweetener acesulfame was analyzed as a wastewater indicator in surface water samples collected from urban and rural settings in southern Ontario, Canada. This interpretation is supported by the concurrence of seasonal fluctuations of glyphosate and AMPA concentrations. Herbicide applications in larger urban centres and along major transportation corridors appear to be important sources of glyphosate and AMPA in surface water, in addition to uses of this herbicide in rural and mixed use areas. Fluctuations in concentrations of acesulfame and glyphosate residues were found to be related to hydrologic events. - Highlights: • Widespread occurrence of glyphosate and AMPA in surface waters of southern Ontario. • Linked to applications of glyphosate in urban and rural settings. • Supported by lack of correlation between AMPA and the wastewater tracer acesulfame. • Contrasts with view that AMPA found in the environment is derived from wastewater. • AMPA more persistent than glyphosate and both fluctuated with hydrological cycles. - The occurrence of AMPA in streams in southern Ontario is linked mainly to glyphosate rather than wastewater sources

Ontario Hydro have established a reliability program in support of its substantial nuclear program. Application of the reliability program to achieve both production and safety goals is described. The value of such a reliability program is evident in the record of Ontario Hydro's operating nuclear stations. The factors which have contributed to the success of the reliability program are identified as line management's commitment to reliability; selective and judicious application of reliability methods; establishing performance goals and monitoring the in-service performance; and collection, distribution, review and utilization of performance information to facilitate cost-effective achievement of goals and improvements.

Trade-offs between wood supply and caribou habitat in northwestern Ontario

Directory of Open Access Journals (Sweden)

Daniel McKenney

1998-03-01

Full Text Available Woodland caribou habitat management in northwestern Ontario is a complex spatial problem. The Strategic Forest Management Model (SFMM, a linear programming PC-based planning tool being developed in Ontario, was used to examine the impacts of alternative management strategies on caribou habitat. The management alternatives investigated included the cessation of timber management and maximising the present value of wood production without any explicit concern (in the model for caribou. Three major findings are worth noting: 1 trying to maintain prime caribou habitat within active Forest Management Units will come at a cost to wood supply but the cost will depend on the absolute amount of area affected and the spatial configuration of that land in relation to mills. The cost of maintaining caribou habitat in one management unit at a level about 25 000 hectares is roughly $324 000 per year (about 3 cents for each Ontario resident. The imposition of an even-flow constraint on wood production is in fact potentially more costly; 2 Given the region is heavily dominated by spruce aged 90 years and over, forest succession and fire disturbance will likely cause large declines in prime caribou habitat in the near to medium term (20 to 40 years even if no timber harvesting occurs; 3 The complexities of the trade-offs in this resource management problem highlight the limitations of any single modelling tool to satisfactorily address all issues. Planners need to take advantage of a wide range of analytical techniques to quantify the issues and formulate integrated policies.

Dynamics of turbidity plumes in Lake Ontario. [Welland Canal and Niagara, Genesee, and Oswego Rivers

Science.gov (United States)

Pluhowski, E. J. (Principal Investigator)

1975-01-01

The author has identified the following significant results. Large turbidity features along the 275 km south shore of Lake Ontario were analyzed using LANDSAT-1 images. The Niagara River plume, ranging from 30 to 500 sq km in area is, by far, the largest turbidity feature in the lake. Based on image tonal comparisons, turbidity in the Welland Canal is usually higher than that in any other water course discharging into the lake during the shipping season. Less turbid water enters the lake from the Port Dalhousie diversion channel and the Genesee River. Relatively clear water resulting from the deposition of suspended matter in numerous upstream lakes is discharged by the Niagara and Oswego Rivers. Plume analysis corroborates the presence of a prevailing eastward flowing longshore current along the entire south shore. Plumes resulting from beach erosion were detected in the images. Extensive areas of the south shore are subject to erosion but the most severely affected beaches are situated between Fifty Mile Point, Ontario and Thirty Mile Point, New York along the Rochester embayment, and between Sodus Bay and Nine Mile Point.

Enhancement of Afterimage Colors by Surrounding Contours

Directory of Open Access Journals (Sweden)

Takao Sato

2011-05-01

Full Text Available Presenting luminance contours surrounding the adapted areas in test phase enhances color afterimages in both duration and color appearance. The presence of surrounding contour is crucial to some color phenomenon such as van Lier's afterimage, but the contour-effect itself has not been seriously examined. In this paper, we compared the contour-effect to color afterimages and to actually colored patches to examine the nature of color information subserving color-aftereffect. In the experiment, observers were adapted for 1 sec to a small colored square (red, green, yellow, or blue presented on a gray background. Then, a test field either with or without surrounding contour was presented. Observers matched the color of a test-patch located near the afterimage to the color of afterimage. It was found that the saturation of negative afterimage was almost doubled by the presence of surrounding contours. There was no effect of luminance contrast or polarity of contours. In contrast, no enhancement of saturation by surrounding contours was observed for actually colored patches even though the colors of patches were equalized to that of afterimage without contours. This dissociation in the contour-effect demonstrates the crucial difference between the color information for aftereffects and for ordinary bottom-up color perception.

An aerial radiological survey of the Oak Ridge Reservation and surrounding area, Oak Ridge, Tennessee

Maurer, R.J.

1989-09-01

An aerial radiological survey of the Oak Ridge Reservation (ORR) and surrounding area in Oak Ridge, Tennessee, was conducted from September 12--29, 1989. The purpose of the survey was to measure and document the site's terrestrial radiological environment for use in effective environmental management and emergency response planning. The aerial survey was flown at an altitude of 91 meters (300 feet) along a series of parallel lines 152 meters (500 feet) apart. The survey encompassed an area of 440 square kilometers (170 square miles) as defined by the Tennessee Valley Authority Map S-16A of the entire Oak Ridge Reservation and adjacent area. The results of the aerial survey are reported as inferred exposure rates at 1 meter above ground level (AGL) in the form of a radiation contour map. Typical background exposure rates were found to vary from 5 to 14 microroentgens per hour (μR/h). The man-made radionuclides, cobalt-60, cesium-137, and protactinium-234m (a radioisotope indicative of depleted uranium), were detected at several facilities on the site. In support of the aerial survey, ground-based exposure rate and soil sample measurements were obtained at several locations within the survey boundary. In addition to the large scale aerial survey, two special flyovers were requested by the Department of Energy. The first request was to conduct a survey of a 1-mile x 2-mile area in south Knoxville, Tennessee. The area had been used previously to store contaminated scrap metals from operations at the Oak Ridge site. The second request was to fly several passes over a 5-mile length of railroad tracks leading from the Oak Ridge Y-12 Plant, north through the city of Oak Ridge. The railroad tracks had been previously used in the transport of cesium-137

Aerial radiological survey of the Three Mile Island Nuclear Station and surrounding area, Middletown, Pennsylvania

Colton, D.P.

1983-08-01

An aerial radiological survey was performed over the area surrounding the Three Mile Island Nuclear Station during October 26 to 30, 1982. The survey covered an 82-square-kilometer area centered on the nuclear plant and encompassed the communities of Middletown, York Haven, Goldsboro and Royalton, Pennsylvania. The highest radiation exposure rates, up to a maximum of 200 microroentgens per hour (μR/h), were inferred from data measured directly over the TMI facilities. This detected radiation was due to the presence of cobalt-58, cobalt-60 and cesium-137, which was consistent with normal plant operations. Similar activity is routinely observed in aerial surveys over nuclear power plants which have been or are presently in an operational mode. For the remainder of the survey area, the inferred radiation exposure rates varied from 6 to 14 μR/h. The reported exposure rate values include an estimated cosmic ray contribution of 3.7 μR/h. Ground-based measurements, conducted during the time of the aerial survey, were compared to the aerial results. Pressurized ionization chamber readings and a group of soil samples were acquired at several locations within the survey area, along the river banks upstream and downstream of the survey area, and at the ground-based locations used for a previous aerial survey which was conducted in 1976. The exposure rate values obtained from these measurements were in agreement with the corresponding aerial data. With the exception of the activity observed within the TMI facilities, no evidence of any contamination which might have occurred as a result of past reactor operations or the 1979 TMI Unit 2 accident was detected from the aerial survey data. This was further supported by the results of the soil sample analyses and the comparison with the 1976 aerial survey data. 7 references, 12 figures, 4 tables

Chang'e-3 (CE-3) landed on the Mare Imbrium basin in the east part of Sinus Iridum (19.51°W, 44.12°N), which was China's first soft landing on the Moon and it started collecting data on the lunar surface environment. To better understand the environment of this region, this paper utilizes the available high-resolution topography data, image data and geological data to carry out a detailed analysis and research on the area surrounding the landing site (Sinus Iridum and 45 km×70 km of the landing area) as well as on the topography, landform, geology and lunar dust of the area surrounding the landing site. A general topographic analysis of the surrounding area is based on a digital elevation model and digital elevation model data acquired by Chang'e-2 that have high resolution; the geology analysis is based on lunar geological data published by USGS; the study on topographic factors and distribution of craters and rocks in the surrounding area covering 4 km×4 km or even smaller is based on images from the CE-3 landing camera and images from the topographic camera; an analysis is done of the effect of the CE-3 engine plume on the lunar surface by comparing images before and after the landing using data from the landing camera. A comprehensive analysis of the results shows that the landing site and its surrounding area are identified as typical lunar mare with flat topography. They are suitable for maneuvers by the rover, and are rich in geological phenomena and scientific targets, making it an ideal site for exploration

From promise to crisis : lessons for Atlantic Canada from Ontario's electricity liberalisation

International Nuclear Information System (INIS)

Adams, T.

2000-01-01

This report synthesized some lessons learned from Ontario's electric power restructuring and showed how they can be applied to reform the Atlantic Canada's electricity sector. Since the opening of Ontario electricity markets to competition, numerous problems have threatened the potential of the power sector to deliver reasonably priced, reliable and environmentally responsible electricity to consumers in Ontario. The original vision of power restructuring in Ontario called for the break-up of Ontario Hydro, the privatisation of major components of the power system, major regulatory improvements, more stringent environmental rules, the creation of an independent agency responsible for power system reliability, and the opening of electricity markets to competition. This original vision has failed for many reasons, including failure to establish a firm date for the opening of the electricity market, a lack of financial accountability, continued subsidies to industrial customers, local distribution rate shock, lack of investment, politicizing transmission tariffs, aggressive marketers exploiting consumer uncertainty and ill-advised deregulation of fossil emissions. It was emphasized that Atlantic Canada could benefit from any eventual electricity restructuring by avoiding these mistakes made in Ontario. This report also described the contents of an 8 point program that was recommended by the author. 21 refs

Facing the challenges of nuclear power at Ontario Power Generation

International Nuclear Information System (INIS)

Howes, H.

1999-01-01

Nuclear power represents a major portion of Ontario Power Generation's generation mix and it will be the bedrock upon which we build a successful, competitive company. Our nuclear units offer many environmental and economic benefits, the one most relevant to this meeting is their significant contribution to the relatively low carbon intensity of Ontario's and Canada's electricity supply. In recent weeks, we have listened with great interest to the endorsement by our federal Minister of the Environment of nuclear technology as a means of reducing global warming. But endorsements of this type alone are not sufficient to ensure that nuclear remains an acceptable option for managing greenhouse gas emissions. Without public acceptance and support, the entire nuclear investment is endangered. At OPG we face three challenges to building this public support: we must continue to improve our safety margins and operating performance; we must continue to improve the environmental performance at our stations; and we must increase our community outreach. Today I would like to focus on the last two challenges and the actions that we are taking to maintain our social and environmental 'licence to operate.' But before I describe these initiatives, I will tell you about: the new company - Ontario Power Generation; the changes in store for Ontario's electricity sector; and our greenhouse gas emissions - the legacy from Ontario Hydro.

Watkins, J. M.; Weidel, Brian M.; Rudstam, L. G.; Holek, K. T.

2014-01-01

Increasing water clarity in Lake Ontario has led to a vertical redistribution of phytoplankton and an increased importance of the deep chlorophyll layer in overall primary productivity. We used in situ fluorometer profiles collected in lakewide surveys of Lake Ontario in 2008 to assess the spatial extent and intensity of the deep chlorophyll layer. In situ fluorometer data were corrected with extracted chlorophyll data using paired samples from Lake Ontario collected in August 2008. The deep chlorophyll layer was present offshore during the stratified conditions of late July 2008 with maximum values from 4-13 μg l-1 corrected chlorophyll a at 10 to 17 m depth within the metalimnion. Deep chlorophyll layer was closely associated with the base of the thermocline and a subsurface maximum of dissolved oxygen, indicating the feature's importance as a growth and productivity maximum. Crucial to the deep chlorophyll layer formation, the photic zone extended deeper than the surface mixed layer in mid-summer. The layer extended through most of the offshore in July 2008, but was not present in the easternmost transect that had a deeper surface mixed layer. By early September 2008, the lakewide deep chlorophyll layer had dissipated. A similar formation and dissipation was observed in the lakewide survey of Lake Ontario in 2003.

A regional study of the radiation environment of Greenham Common, Newbury District and surrounding areas

International Nuclear Information System (INIS)

1997-02-01

This study was commissioned by Newbury District Council and Basingstoke and Deane Borough Council in response to public concern following disclosures about events at Greenham Common in the 1950s, and the suspicion that there may have been an accident involving a nuclear weapon leading to off-site contamination at the airbase. The Greenham Common airbase is at an advanced stage of decommissioning with parts of the site already re-developed for industrial and leisure purposes and material being removed for use in construction of the Newbury by-pass. The success of such developments is critically dependent on public confidence in the quality of the environment, both near the site, and more generally throughout the area. For this reason the study was commissioned with the aims of: I. defining the radiation environment of the whole district and parts of its surrounding areas. II. examining whether there is any evidence of radioactive contamination in the vicinity of the Greenham Common airbase. III. assessing the evidence that there may have been a release of nuclear material from the site. The work involved a collaboration between scientists from the Scottish Universities Research and Reactor Centre, who conducted gamma ray surveys to define the general radiation environment of the area, and Scientists from the University of Southampton who collected an extensive range of samples for high sensitivity radiochemical analyses. This report presents their findings and main conclusions, together with a discussion of the background to the study and its implications. (Author)

The role of LDCs in conservation and demand management in 2007 : the Ontario Clean Air Alliance's response to the Ontario Power Authority's options paper

International Nuclear Information System (INIS)

Gibbons, J.

2006-01-01

A response to The Ontario Power Authority (OPA) discussion paper on the role of local distribution companies (LDC) was presented, with reference to conservation and demand management (CDM). This paper examined 2 implicit issues raised by the OPA paper: (1) the appropriate role of the OPA with respect to conservation and demand management, and (2) the role of the Ontario Energy Board (OEB) in streamlining its CDM regulatory approval process. It was suggested that LDCs are ideal agencies for the delivery of CDM as they are trusted sources of energy information and have existing business relationships with electricity consumers. Local electric utilities understand local conditions and needs and are better placed to meet them. Ontario's electric utilities are now eligible for conservation profit bonuses equal to 5 per cent of the bill savings that their energy efficiency programs create for customers. It was noted that the benefits of CDM programs have already been demonstrated. The establishment of CDM budget targets was advised. Options to finance CDM programs were reviewed, as well as various energy efficiency programs. It was suggested that the OPA should continue to be a strong public advocate for CDM, and promote stricter provincial and federal energy efficiency standards. Recommendations for streamlining the OEB's CDM regulatory approval process were presented. It was concluded that marginalizing the role of Ontario's electric utilities in the delivery of CDM programs will short-circuit Ontario's efforts to develop a conservation culture. 13 refs

Wet Snow Mapping in Southern Ontario with Sentinel-1A Observations

Science.gov (United States)

Chen, H.; Kelly, R. E. J.

2017-12-01

Wet snow is defined as snow with liquid water present in an ice-water mix. It is can be an indicator for the onset of the snowmelt period. Knowledge about the extent of wet snow area can be of great importance for the monitoring of seasonal snowmelt runoff with climate-induced changes in snowmelt duration having implications for operational hydrological and ecological applications. Spaceborne microwave remote sensing has been used to observe seasonal snow under all-weather conditions. Active microwave observations of snow at C-band are sensitive to wet snow due to the high dielectric contrast with non-wet snow surfaces and synthetic aperture radar (SAR) is now openly available to identify and map the wet snow areas globally at relatively fine spatial resolutions ( 100m). In this study, a semi-automated workflow is developed from the change detection method of Nagler et al. (2016) using multi-temporal Sentinel-1A (S1A) dual-polarization observations of Southern Ontario. Weather station data and visible-infrared satellite observations are used to refine the wet snow area estimates. Wet snow information from National Operational Hydrologic Remote Sensing Center (NOHRSC) is used to compare with the S1A estimates. A time series of wet snow maps shows the variations in backscatter from wet snow on a pixel basis. Different land cover types in Southern Ontario are assessed with respect to their impacts on wet snow estimates. While forests and complex land surfaces can impact the ability to map wet snow, the approach taken is robust and illustrates the strong sensitivity of the approach to wet snow backscattering characteristics. The results indicate the feasibility of the change detection method on non-mountainous large areas and address the usefulness of Sentinel-1A data for wet snow mapping.

Multi-temporal Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data were utilized in a Geographic Information System (GIS) to evaluate changes in landuse II and cover in the area surrounds the Suez Canal, Egypt. The area is bounded by the Great Bitter Lake from the south, El Qantara city from the north, Nile Delta from the west, and Sinai Peninsula from the east. The area witnessed a rapid development in the past three decades, and the environmental changes were very remarkable. The data collected by Landsat sensors, TM (1984) and ETM+ (2000) were used to conduct a change detection and landuse analysis over the area of study. Both images were spatially registered and band four (Near Infra-Red) was radiometrically normalized to eliminate the atmospheric and sun luminance variation. Band algebra techniques were implemented to generate a reflectance difference image. On the other hand, the images were classified with supervised (maximum likelihood) technique with the help of ground truth data to provide the landuse maps for 1984 and 2000 periods. These maps were converted to GIS environment and final landuse changes have been provided

Due to their importance as pollinators of many plant species, this study aimed to know the nest density, spatial distribution, and nesting substrates used by Xylocopa species in the Caatinga, a xerophilous vegetation of Northeastern Brazil. Three areas of Caatinga in the surroundings of passion fruit crops were sampled. The bee species found in these areas were Xylocopa grisescens Lepeletier and Xylocopa frontalis (Olivier). All nests were in Commiphora leptophloeos (Burseraceae) trees (n = 113). Phytosociological analysis showed that this tree species presented the highest absolute density (212.5 individuals/ha) and index of importance value (52.7). The distribution pattern of the C. leptophloeos was aggregated. The nests were located in dead and dried branches with an average diameter of 5.3 ± 2.0 cm (n = 43). The mean number of nests/tree was 3.1 ± 2.8 (n = 113). The less disturbed area showed 6.7 nests/ha and 4.2 nests/tree. In the disturbed areas, 0.9 nests/ha and 2.4 to 2.7 nests/tree were observed. The availability of substrate for nesting in the studied areas and its importance as a limiting factor for nesting are discussed.

Full Text Available Abstract Introduction Continued action is needed to tackle health inequalities in Canada, as those of lower income continue to be at higher risk for a range of negative health outcomes. There is arguably a lack of political will to implement policy change in this respect. As a result, we investigated public awareness of income-related health inequalities in a generally representative sample of Ontarians in late 2010. Methods Data were collected from 2,006 Ontario adults using a telephone survey. The survey asked participants to agree or disagree with various statements asserting that there are or are not health inequalities in general and by income in Ontario, including questions pertaining to nine specific conditions for which inequalities have been described in Ontario. A multi-stage process using binary logistic regression determined whether awareness of health inequalities differed between participant subgroups. Results Almost 73% of this sample of Ontarians agreed with the general premise that not all people are equally healthy in Ontario, but fewer participants were aware of health inequalities between the rich and the poor (53%–64%, depending on the framing of the question. Awareness of income-related inequalities in specific outcomes was considerably lower, ranging from 18% for accidents to 35% for obesity. Conclusions This is the first province-wide study in Canada, and the first in Ontario, to explore public awareness on health inequalities. Given that political will is shaped by public awareness and opinion, these results suggest that greater awareness may be required to move the health equity agenda forward in Ontario. There is a need for health equity advocates, physicians and researchers to increase the effectiveness of knowledge translation activities for studies that identify and explore health inequalities.

Utilizing NASA Earth Observations to Model Volcanic Hazard Risk Levels in Areas Surrounding the Copahue Volcano in the Andes Mountains

Copahue is a stratovolcano located along the rim of the Caviahue Caldera near the Chile-Argentina border in the Andes Mountain Range. There are several small towns located in proximity of the volcano with the two largest being Banos Copahue and Caviahue. During its eruptive history, it has produced numerous lava flows, pyroclastic flows, ash deposits, and lahars. This isolated region has steep topography and little vegetation, rendering it poorly monitored. The need to model volcanic hazard risk has been reinforced by recent volcanic activity that intermittently released several ash plumes from December 2012 through May 2013. Exposure to volcanic ash is currently the main threat for the surrounding populations as the volcano becomes more active. The goal of this project was to study Copahue and determine areas that have the highest potential of being affected in the event of an eruption. Remote sensing techniques were used to examine and identify volcanic activity and areas vulnerable to experiencing volcanic hazards including volcanic ash, SO2 gas, lava flow, pyroclastic density currents and lahars. Landsat 7 Enhanced Thematic Mapper Plus (ETM+), Landsat 8 Operational Land Imager (OLI), EO-1 Advanced Land Imager (ALI), Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Shuttle Radar Topography Mission (SRTM), ISS ISERV Pathfinder, and Aura Ozone Monitoring Instrument (OMI) products were used to analyze volcanic hazards. These datasets were used to create a historic lava flow map of the Copahue volcano by identifying historic lava flows, tephra, and lahars both visually and spectrally. Additionally, a volcanic risk and hazard map for the surrounding area was created by modeling the possible extent of ash fallout, lahars, lava flow, and pyroclastic density currents (PDC) for future eruptions. These model results were then used to identify areas that should be prioritized for disaster relief and evacuation orders.

To determine the prevalence rates and characteristics of past-year mental health consultation for Ontario's adult (18 + years old) immigrant populations. The Canadian Community Health Survey (CCHS) 2012 was used to calculate the prevalence rates of past-year mental health consultation by service provider type. Characteristics associated with mental health consultation were determined by carrying out multivariable logistic regression analysis on merged CCHS 2008-2012 data. Adult immigrant populations in Ontario (n = 3995) had lower estimated prevalence rates of past-year mental health consultation across all service provider types compared to Canadian-born populations (n = 14,644). Amongst those who reported past-year mental health consultation, 57.89% of Ontario immigrants contacted their primary care physician, which was significantly higher than the proportion who consulted their family doctor from Canadian-born populations (45.31%). The factors of gender, age, racial/ethnic background, education level, working status, food insecurity status, self-perceived health status, smoking status, alcohol drinking status, years since immigration, and age at time of immigration were significantly associated with past-year mental health consultation for immigrant populations. Ontario's adult immigrant populations most commonly consult their family doctor for mental health care. Potential exists for expanding the mental health care role of primary care physicians as well as efforts to increase accessibility of specialized mental health services. Integrated, coordinated care where primary care physicians, specialized mental health professionals, social workers, and community educators, etc. working together in a sort of "one-stop-shop" may be the most effective way to mitigate gaps in the mental health care system. In order to effectively tailor mental health policy, programming, and promotion to suit the needs of immigrant populations initiatives that focus on

We documented the extent of point-of-sale (POS) lottery promotions in Ontario, Canada and the relationship between lottery promotions and store and city characteristics. This is the first quantitative study of POS lottery promotions. A total of 366 stores-independent and chain convenience stores, gas stations and grocery stores-were visited across 20 cities in Ontario. Data collectors unobtrusively observed the type of lottery promotions in each store and completed a data collection checklist. A lottery promotion index was created and hierarchical linear modeling (HLM) was conducted to examine the relationship between extent of lottery promotions and independent variables such as neighbourhood socioeconomic status and city prevalence of lottery ticket purchasing. POS lottery promotions were widespread across Ontario, with the highest level of promotion found in independent convenience stores. In the multivariable HLM model, none of the remaining independent variables remained statistically significant, except for store type. Lottery promotions are extensive at the POS in Ontario. These findings can help initiate discussions around the appropriateness and possible future regulation of this form of advertising.

Interconnection issues in Ontario : a status check

International Nuclear Information System (INIS)

Helbronner, V.

2010-01-01

This PowerPoint presentation discussed wind and renewable energy interconnection issues in Ontario. The province's Green Energy Act established a feed-in tariff (FIT) program and provided priority connection access to the electricity system for renewable energy generation facilities that meet regulatory requirements. As a result of the province's initiatives, Hydro One has identified 20 priority transmission expansion projects and is focusing on servicing renewable resource clusters. As of October 2010, the Ontario Power Authority (OPA) has received 1469 MW of FIT contracts executed for wind projects. A further 5953 MW of wind projects are awaiting approval. A Korean consortium is now planning to develop 2500 MW of renewable energy projects in the province. The OPA has also been asked to develop an updated transmission expansion plan. Transmission/distribution availability tests (TAT/DAT) have been established to determine if there is sufficient connection availability for FIT application projects. Economic connection tests (ECTs) are conducted to assess whether grid upgrade costs to enable additional FIT capacity are justifiable. When projects pass the ECT, grid upgrades needed for the connection included in grid expansion plans. Ontario's long term energy plan was also reviewed. tabs., figs.

2014-06-03

Watershed mercury (Hg) flux was calculated for ten inflowing rivers and the outlet for Lake Ontario using empirical measurements from two independent field-sampling programs. Total Hg (THg) flux for nine study watersheds that directly drain into the lake ranged from 0.2 kg/yr to 13 kg/yr, with the dominant fluvial THg load from the Niagara River at 154 kg/yr. THg loss at the outlet (St. Lawrence River) was 68 kg/yr and has declined approximately 40% over the past decade. Fluvial Hg inputs largely (62%) occur in the dissolved fraction and are similar to estimates of atmospheric Hg inputs. Fluvial mass balances suggest strong in-lake retention of particulate Hg inputs (99%), compared to dissolved total Hg (45%) and methyl Hg (22%) fractions. Wetland land cover is a good predictor of methyl Hg yield for Lake Ontario watersheds. Sediment deposition studies, coupled atmospheric and fluvial Hg fluxes, and a comparison of this work with previous measurements indicate that Lake Ontario is a net sink of Hg inputs and not at steady state likely because of recent decreases in point source inputs and atmospheric Hg deposition.

Since 1979 June, geolgical, geophysical and hydro-geological investigations have been conducted at Research Area 4 north of Atikokan, Ontario as part of the Canadian Nuclear Fuel Waste Management Program. Composition, shape and internal structure of the Eye-Dashwa pluton were the subjects of regional field studies. Detailed research concentrated on the detection and characterization of surface and subsurface fractures within a 400-m x 800-m grid area, where five boreholes were drilled to depths of between 200 m and 1100 m. Fracture zones in the area were readily detected by surface mapping, ground very low frequency electromagnetic (VLF-EM) surveys and borehole logging. Borehole logs, downhole tube-wave seismic surveys, and thermal and television logging were successful in detecting open fractures in boreholes

Precipitation Depth-Duration-Frequency Analysis for the Nevada National Security Site and Surrounding Areas

Accurate precipitation frequency data are important for Environmental Management Soils Activities on the Nevada National Security Site (NNSS). These data are important for environmental assessments performed for regulatory closure of Soils Corrective Action Unit (CAU) Sites, as well as engineering mitigation designs and post-closure monitoring strategies to assess and minimize potential contaminant migration from Soils CAU Sites. Although the National Oceanic and Atmospheric Administration (NOAA) Atlas 14 (Bonnin et al., 2011) provides precipitation frequency data for the NNSS area, the NNSS-specific observed precipitation data were not consistent with the NOAA Atlas 14 predicted data. This is primarily due to the NOAA Atlas 14 products being produced from analyses without including the approximately 30 NNSS precipitation gage records, several of which approach or exceed 50 year of record. Therefore, a study of precipitation frequency that incorporated the NNSS precipitation gage records into the NOAA Atlas 14 dataset, was performed specifically for the NNSS to derive more accurate site-specific precipitation data products. Precipitation frequency information, such as the depth-duration-frequency (DDF) relationships, are required to generate synthetic standard design storm hydrographs and assess actual precipitation events. In this study, the actual long-term NNSS precipitation gage records, some of which are the longest gage records in southern and central Nevada, were analyzed to allow for more accurate precipitation DDF estimates to be developed for the NNSS. Gridded maps of precipitation frequency for the NNSS and surrounding areas were then produced.

Analysis of small-scale biogas utilization systems on Ontario cattle farms

International Nuclear Information System (INIS)

White, Andrew J.; Kirk, Donald W.; Graydon, John W.

2011-01-01

The production of biogas through the anaerobic digestion of cattle manure and its subsequent use in the generation of electricity on larger farms in Ontario is currently economically attractive. This is a result of the Ontario Feed-In Tariff (FIT) program, which provides incentivized rates for the production of electricity from biogas. Although larger farms can take advantage of the higher rates for electricity, there are substantially more smaller farms for which individually designed and engineered biogas systems would be prohibitively expensive. By employing the concept of modular biogas plants, this analysis evaluates the economics of small-scale biogas utilization systems. Dairy farms with at least 33 animals and beef farms with at least 78 animals can operate economically attractive biogas systems. This analysis shows that approximately 9000 additional Ontario cattle farms would be able to take advantage of the FIT program, which would add 120 MW e of renewable energy capacity to the Ontario electrical grid.

Ontario's long-term energy plan, building our clean energy future

International Nuclear Information System (INIS)

2010-01-01

The first energy priority of the plan is to provide all Ontarians with a clean, modern and reliable electricity system. It gives a summary of the means implemented to help families and businesses with increasing electricity costs. The plan is to shift the province from a coal-dependent system. Over the next 20 years, 15,000 MW (megawatt) of generating capacity will have to be rebuilt or constructed to replace older Ontario's energy infrastructures. In Ontario, an increase of about 3.5% per year in residential prices, resulting from the need to enjoy clean air, reliable generation and modernized transmission, is expected to occur over the next two decades. The expected electricity needs in Ontario and efficient means to satisfy them are described in this plan.

Policy communities and allocation of internalized cost : negotiation of the Ontario acid rain program, 1982-1985

1997-12-31

The process of allocating the internalized cost of environmental protection amongst industrial concerns and governments was studied. The issue was addressed by reviewing the literature on the treatment of externalities by economists, and the literature describing the approach to policy analysis by the the policy communities. An examination of a case study in which the cost of sulphur dioxide emission reductions was allocated amongst the major Ontario sources during the development of the 1985 national and Ontario acid rain programs was presented. The study provided an insight into issues regarding Canadian environmental policy and policy communities theory and practice. The Ontario allocation was negotiated by Ontario alone, even though it was part of a national program. The environmental movement also had no role in this Ontario policy decisions. The power to influence the Ontario cabinet belonged to MOE, Inco, and Ontario Hydro through negotiations and compromise, which conforms to the basic premise of the policy communities approach.

The province of Ontario continues to experience measles virus transmissions despite the elimination of measles in Canada. We describe an unusual outbreak of measles in Ontario, Canada, in early 2015 that involved cases with a unique strain of virus and no known association among primary case-patients. A total of 18 cases of measles were reported from 4 public health units during the outbreak period (January 25-March 23, 2015); none of these cases occurred in persons who had recently traveled. Despite enhancements to case-patient interview methods and epidemiologic analyses, a source patient was not identified. However, the molecular epidemiologic analysis, which included extended sequencing, strongly suggested that all cases derived from a single importation of measles virus genotype D4. The use of timely genotype sequencing, rigorous epidemiologic investigation, and a better understanding of the gaps in surveillance are needed to maintain Ontario's measles elimination status.

Towards a sustainable electricity system for Ontario : interim report

International Nuclear Information System (INIS)

2004-04-01

More changes have occurred in Ontario's electricity sector in the past 5 years than over the preceding 9 decades since the creation of Ontario Hydro Electric Power Commission in 1906. The province's nuclear generating facilities were taken out of service in 1997 for safety and maintenance overhauls. The existing nuclear facilities, which account for 28 per cent of the province's generating capacity, will reach the end of their operational lifetimes by 2018. The government of Ontario also announced the phasing out of Ontario Power Generation's coal-fired plants by 2007 due to the environmental health impacts of their operation. These changes have ignited debate over the province's future electricity needs and how they might be met. This study examined by how much electricity demand in Ontario could be reduced through the adoption of energy efficient technologies, fuel switching, cogeneration and demand response measures. It also examined how much future supply could be obtained from renewable energy sources such as wind, the upgrading of existing hydroelectric facilities, and the development of new solar, biomass and small-scale hydro facilities. It also examined how to accommodate the remaining grid demand and which public policies should be adopted to maximize efficiency and other demand side measures. The impacts of the policies were simulated using the Canadian Integrated Modelling System (CIMS) computer model developed by the Energy and Materials Research Group at Simon Fraser University. The CIMS simulations were conducted under the assumptions that barriers to cogeneration would be removed, financial incentives would be provided along with innovative financing programs. The study revealed that capital investments of $18.2 billion over the 2005-2020 period would be required to reduce peak demand of 12,300 MW relative to the business and usual forecast through efficiency, fuel switching and cogeneration. 13 refs., 8 tabs

A field study was conducted in the lower Great Lakes to assess changes in spatial distribution and population structure of dreissenid mussel populations. More specifically, the westward range expansion of quagga mussel into western Lake Erie and toward Lake Huron was investigated and the shell size, density, and biomass of zebra and quagga mussel with depth in southern Lake Ontario in 1992 and 1995 were compared. In Lake Erie, quagga mussel dominated the dreissenid community in the eastern basin and zebra mussel dominated in the western basin. In southern Lake Ontario, an east to west gradient was observed with the quagga mussel dominant at western sites and zebra mussel dominant at eastern locations. Mean shell size of quagga mussel was generally larger than that of zebra mussel except in western Lake Erie and one site in eastern Lake Erie. Although mean shell size and our index of numbers and biomass of both dreissenid species increased sharply in southern Lake Ontario between 1992 and 1995, the increase in density and biomass was much greater for quagga mussels over the 3-year period. In 1995, zebra mussels were most abundant at 15 to 25 m whereas the highest numbers and biomass of quagga mussel were at 35 to 45 m. The quagga mussel is now the most abundant dreissenid in areas of southern Lake Ontario where the zebra mussel was once the most abundant dreissenid; this trend parallels that observed for dreissenid populations in the Dneiper River basin in the Ukraine.

The authors document the status of Lake Ontario's open-water fish community in 1972, near the beginning of an era of massive fish stocking and when phosphorus levels in the lake from anthropogenic inputs, were near their peak. They then describe changes that occurred in the fish community in 1978-98. This was a period when large numbers of young salmonid piscivores were released annually, sea lamprey control continued to improve, and phosphorus levels were declining due to successful nutrient abatement programs. Coincident with the above, the lower food web was changed by the addition of new exotic invertebrates, the zooplankter Bythotrephes cederstroemi and particularly the zebra mussel, Dreissena polymorpha, and quagga mussel, D. bugensis. The picture of the fish community structure is drawn from records of catches in bottom trawls and gill nets during surveys of southern Lake Ontario conducted the the U.S. Geological Survey (USGS) and the New York Department of Environmental Conservation (NYDEC), from records of fish stocked in Lake Ontario by the NYDEC, and from a creel census of boat anglers returning to southern Lake Ontario ports conducted by the NYDEC.

Cord stem-cell transplantation in Ontario: do we need a public bank?

Gassas, A

2011-06-01

It has been 21 years since the first successful use of umbilical cord blood as a source of donor cells for hematopoietic stem cell transplantation (HSCT). Over those years, cord blood transplantation (CBT) has shown marked success as an effective modality in the treatment of children and adults with hematologic malignancies, marrow failure, immunodeficiency, hemoglobinopathy, and inherited metabolic diseases. Furthermore, transplantation without full human leukocyte antigen (HLA) matching is possible and, despite a lower incidence of graft-versus-host disease, graft-versus-leukemia effect is preserved. More than 20,000 cbts have been performed worldwide. Ontario is the most populated province in Canada, and its cbt numbers have increased dramatically in recent years, but most of the umbilical cord blood units are purchased from unrelated international registries. There is no public cord bank in Ontario, but there is a private cord banking option, and notably, Ontario has the largest number of live births in Canada [approximately 40% of all Canadian live births per year occur in Ontario (Statistics Canada, 2007)]. In this brief review, the pros and cons of private and public cord banking and the feasibility of starting an Ontario public cord bank are discussed.

An aerial radiological survey was conducted over the Perry Nuclear Power Plant, North Perry, Ohio. The purpose of the 234-square-kilometer (91-square-mile) survey was to document the terrestrial gamma environment of the plant and surrounding area. An exposure rate contour map at 1 meter above ground level was constructed from the gamma data and overlaid on an aerial photograph and map of the area. Exposure rates increased from 0 microroentgens per hour (μR/h) over Lake Erie to 9 μR/h as the distance from Lake Erie increased. Only one anomalous area appears on the map, which is due to an excess of Bi-214 in a landfill area. Ground-based exposure rate measurements and soil samples were obtained to support the aerial data. Oblique aerial photographs of the plant were also acquired during the survey. 6 refs., 6 figs., 1 tab

Full Text Available Considering the importance of plant diversity and to evaluate the effect of grazing pressure on species richness and structure of plant communities, this experiment was conducted at Golestan National Park and its surrounding areas in the north east of Iran. Sampling was conducted in intact and abandoned habitats and habitats under seasonal and heavy grazing, using Modified Whitaker Plot in 1, 10,100 and 1000 m2 spatial scales. Results showed that the composition of plant species from different habitats was different. In addition the increasing intensity of grazing increased the importance of therophytes and decreased the role of hemicryptophytes and phanerophytes and also decreasd the amount of species richness. Mean species richness of studied habitat showed a significant difference in all four sampling spatial scales. The results showed that plant species richness decreased in the areas affected by heavy grazing and conservation against grazing plays an important role in maintaining species richness.

Although stable, intraplate region of eastern Canada is considered low rate deformation area in the North American plate, the retreat of large ice sheets during deglaciation in the last 20 ka has resulted in horizontal and vertical deformation of the Earth's in eastern Ontario. Present-day glacial isostatic adjustment (GIA) uplift rates approach 10 mm/yr or more at Hudson Bay and decrease with distance southeastward. Current GIA models forecast that the hinge line between uplift to the northwest and subsidence to the southeast lies somewhere near the Saint Lawrence valley in eastern Canada [Tushingham and Peltier, 1991; Peltier, 2002]. Employing continuous Global Positioning System (cGPS) observations and high precision tools for processing and then analyzing each component of derived time series are important tools to monitor the associated regional crustal deformation with good accuracies. Here we describe the analysis of coordinate time series of cGPS stations scattered sparsely throughout southeastern Ontario and between Ottawa and the east coast of Hudson Bay. Here, the two most reliable local networks, each including 4 to 6 reference stations, were selected for analysis. Data for period of approximately five years, 2008-2012.9, was processed with Bernese 5.0 over several campaigns. Individual cGPS coordinate time series were generated for each station and basic parameters, such as mean, variance and repeatability, were estimated. The time series are corrected with respect to the rigid plate motion and seasonal variations and advanced time series analysis techniques, including spectral analysis and principal component analysis were implemented. Post-processing of the time series reproduces the general GIA spatial pattern. Results also show that the vertical velocities of all stations in the solution are consistent with the GIA model uplift rate and are consistent with other cGPS sites in eastern Canada and increases from north of lake of Ontario (approximately

2006-01-01

Corporal punishment of children has been used as a disciplinary measure to modify undesirable behavior of children worldwide. This study was conducted with the aim of determining the knowledge, attitudes and the extent that corporal punishment is practiced in the study area. A cross-sectional study was conducted among the residents of Assendabo town and its surroundings area form January 8-12, 2003. A total of 368 residents with at least one child living with them were selected and interviewed using a structured questionnaire. Data were analyzed using SPSS for windows version 11.0. The study revealed 310 (87.6%) of the parents employed child corporal punishment as a method of disciplining out of which nearly half of them claimed their action was for the ultimate benefit of their children. Only 12 (3.5%) of the parents reported infliction of trauma while punishing their children. There was no significant parental difference both in attitude and practice of child corporal punishment. Family income is found to affect both attitude and practice of corporal punishment. From this study it is concluded that the knowledge about the existence of a legal framework which protects a child from any form of abuse is low. The attitude towards avoidance of child corporal punishment is unfavorable and there is a high prevalence of child corporal punishment practiced.

2007-06-01

Full Text Available In this study, selected travel time data from the aftershock series of the Erzincan earthquake (March, 1992, Ms=6.8 were inverted simultaneously for both hypocenter locations and 3D Vp and Vs structure. The general features of the 3D velocity structure of the upper crust of Erzincan Basin and the surrounding area, one of the most tectonically and seismically active regions in Turkey were investigated. The data used for this purpose were 2215 P-wave and 547 S-wave arrival times from 350 local earthquakes recorded by temporary 15 short-period seismograph stations. Thurber’s simultaneous inversion method (1983 was applied to the arrival time data to obtain a 3D velocity structure, and hypocentral locations. Both 3D heterogeneous P and S wave velocity variations down to 12 km depth were obtained. The acquired tomographic images show that the 3D velocity structure beneath the region is heterogeneous in that low velocity appears throughout the basin and at the southeastern flank, and high velocities occur at south and east of the basin. The low velocities can be related to small and large scale fractures, thus causing rocks to weaken over a long period of the active tectonic faulting process. The ophiolitic rock units mostly occurring around the basin area are the possible reason for the high velocities. The validity of 3D inversion results was tested by performing detailed resolution analysis. The test results confirm the velocity anomalies obtained from inversion. Despite the small number of inverted S-wave arrivals, the obtained 3D S velocity model has similar anomalies with lower resolution than the 3D P-wave velocity model. Better hypocenter locations were calculated using the 3D heterogeneous model obtained from tomographic inversion.

Source-receptor relationships for speciated atmospheric mercury at the remote Experimental Lakes Area, northwestern Ontario, Canada

2012-02-01

Full Text Available Source-receptor relationships for speciated atmospheric mercury measured at the Experimental Lakes Area (ELA, northwestern Ontario, Canada were investigated using various receptor-based approaches. The data used in this study include gaseous elemental mercury (GEM, mercury bound to fine airborne particles (<2.5 μm (PHg, reactive gaseous mercury (RGM, major inorganic ions, sulphur dioxide, nitric acid gas, ozone, and meteorological variables, all of which were measured between May 2005 and December 2006. The source origins identified were related to transport of industrial and combustion emissions (associated with elevated GEM, photochemical production of RGM (associated with elevated RGM, road-salt particles with absorption of gaseous Hg (associated with elevated PHg and RGM, crustal/soil emissions, and background pollution. Back trajectory modelling illustrated that a remote site, like ELA, is affected by distant Hg point sources in Canada and the United States. The sources identified from correlation analysis, principal components analysis and K-means cluster analysis were generally consistent. The discrepancies between the K-means and Hierarchical cluster analysis were the clusters related to transport of industrial/combustion emissions, photochemical production of RGM, and crustal/soil emissions. Although it was possible to assign the clusters to these source origins, the trajectory plots for the Hierarchical clusters were similar to some of the trajectories belonging to several K-means clusters. This likely occurred because the variables indicative of transport of industrial/combustion emissions were elevated in at least two or more of the clusters, which means this Hg source was well-represented in the data.

Ontario Hydro at the millennium : has monopoly's moment passed?

1996-01-01

This volume is a collection of 10 papers presented at a conference in which the challenges of restructuring the electric power industry in Ontario were discussed. Legal experts, policy makers, economists and stakeholders in the industry presented their views regarding the future of the industry in Ontario. The implications of privatization were discussed. There was general agreement on the need for some industry de-integration and privatization. However, agreement on the exact nature of the approach to take was more divided. For example, opinion was divided on what the logical endpoint of industry restructuring should be i.e. wholesale or retail competition. Also contentious was the question of what portion of Hydro's generating assets should be sold off to private enterprise if Hydro's generation and transmission assets are unbundled. Opinions were also divided about the environmental consequences of nuclear energy. Significant differences of opinion were evident concerning the privatization of Ontario Hydro's nuclear assets. refs., tabs., figs

Surrounding Moving Obstacle Detection for Autonomous Driving Using Stereo Vision

Directory of Open Access Journals (Sweden)

Hao Sun

2013-06-01

Full Text Available Detection and tracking surrounding moving obstacles such as vehicles and pedestrians are crucial for the safety of mobile robotics and autonomous vehicles. This is especially the case in urban driving scenarios. This paper presents a novel framework for surrounding moving obstacles detection using binocular stereo vision. The contributions of our work are threefold. Firstly, a multiview feature matching scheme is presented for simultaneous stereo correspondence and motion correspondence searching. Secondly, the multiview geometry constraint derived from the relative camera positions in pairs of consecutive stereo views is exploited for surrounding moving obstacles detection. Thirdly, an adaptive particle filter is proposed for tracking of multiple moving obstacles in surrounding areas. Experimental results from real-world driving sequences demonstrate the effectiveness and robustness of the proposed framework.

Market power mitigation, monitoring and surveillance in the Ontario electricity market

Barrett, A.

2001-01-01

This power point presentation discussed the meaning of market power and how Ontario Power Generation's market power is one of the most contentious market implementation issues in the deregulation debate. Market power was described as being the ability to profitably maintain prices above competitive levels for a significant period of time. The presentation referred to the key elements of the market power mitigation framework (MPMF) of Ontario and how it strikes a balance between the three major objectives of creating a competitive marketplace, to pay down the stranded debt, and to ensure viable power generation in the province. It was concluded that there will be a viable competitive market in Ontario in the near future, but a pragmatic, fact-based view of the market is needed to allow market forces to work. It was emphasized that markets by nature are unpredictable and volatility does not necessarily means that the market is not working. The author stated that Ontario Power Generation recognized that it is important to coordinate roles and responsibilities to minimize duplication and reduce confusion. tags., figs

Climatic warming and potential demands for irrigation water in southwest Ontario

Brklacich, M.

1990-01-01

The potential impacts of global warming on demand for irrigation water in southwestern Ontario are discussed. The climatic change scenarios considered derive from the Goddard Institute for Space Studies (GISS) general circulation model, which suggests that the frost-free season in southwestern Ontario will be extended from the current 166 days to 223 days under a doubling of atmospheric carbon dioxide. The 1.76 million ha of agricultural land in southwestern Ontario was disaggregated into 365 unique land units, reflecting regional variability in soil quality, topography and climate. Analyses were conducted for individual crops on each of the land units, and results were aggregated to a regional level. Overall, a longer, warmer but relatively drier crop growing season could be expected in southwestern Ontario under this scenario. Climatic change impacts will vary from crop to crop, and will have a greater impact on corn yield than soybeans or wheat. Yield improvements stemming from irrigation should be greater with corn than with the other two crops. 16 refs., 1 tab

2007-08-01

Full Text Available Concentrations of free cyanide and total cyanide in water samples in Bogoso and its surrounding areas in Ghana have been measured in this study. Concentrations of free cyanide and total cyanide were found to be above the maximum permissible discharge limit of effluent from mining companies into natural waters set by Environmental Protection Agency, Ghana (GEPA. A comparison of the results obtained in this study with permissible levels set by US Environmental Protection Agency and the World Health Organization reveals that surface waters in the study areas are highly polluted with cyanide and it's not safe for human consumptions. This means that, the resident in and around Bogoso are at risk.

Market readiness update : updated status of preparations for Ontario's competitive retail electricity market

International Nuclear Information System (INIS)

2002-01-01

The Market Readiness Project Team of the Ontario Energy Board (OEB) is instrumental in ensuring the readiness of retail participants in Ontario's competitive electricity market. The team, led by the Independent Electricity Market Operator (IMO), provides information and advice regarding the technical readiness of the retail industry, with particular focus on the readiness of distributors to carry out their roles in a competitive market. This report provides an assessment of the team regarding the industry's technical readiness based on information as of April 24, 2002. In January 2002, the Ontario Government announced that it would open the electricity industry to competition on May 1, 2002. 54 of Ontario's 94 licensed electricity distributors claimed they were ready to offer retail choice by May 1. As of March 2002, about 858,000 customers (or 20 per cent of Ontario's 4.2 million customers) had signed a retail electricity contract with one of 9 active electricity retailers. By April 2002, 73 distributors, representing 93 per cent of Ontario's customers signed a contract with a retailer. Those customers who choose not to sign a contract will continue to receive service from their distributor but at energy prices set hourly by the IMO. It is expected that after May 1, the transition to a competitive market will proceed for several weeks as distributors progress through their billing cycles. 7 tabs., 2 figs

Trading our health: Ontario Power Generation's plan to violate its air pollution reduction commitment

International Nuclear Information System (INIS)

Gibbons, J.; Bjorkquist, S.

1999-01-01

Amid growing concerns about nitrogen oxide (Nox) emissions, the Ontario Clean Air Alliance is recommending in this report that the Ontario government restrict Nox emissions from Ontario Power Generation (OPG) in the year 2000 and not let the corporation meet its emissions cap by on a net basis by retiring Pilot Emission Reduction Trading (PERT) Nox emission reduction credits. Instead the alliance believes the Ontario government should require OPG to achieve emissions compliance by curtailing coal-fired electricity exports, purchasing renewable and natural-gas electricity and promoting energy efficiency. OPG's inventory of PERT Nox reduction credits are assessed against whether they will cause an increase in the year 2000 as a result of trading. Ontario Power Generation's Nox emissions are a central chemical component of acid rain and smog and are produced from its coal-fired electricity generators. The utility would like to achieve Nox reductions by establishing demand management programs which would reduce the demand for electricity by 5200 megawatts (MW), by purchasing 3100 MW of non-utility generation and by undertaking combustion process modifications at its Lambton and Nanticoke coal-fired generating stations. It has not met its 2000 demand management and non-utility generation targets, and specifically, as of December 31, 1998, Ontario Hydro's successor companies demand management programs have only reduced electricity demand by approximately 1300 MW. Furthermore, the successor companies will have only approximately 1700 MW of non-utility generation capacity under contract by December 31, 1999. The report describes the criteria for ensuring that Nox emissions trading will not lead to a net increase in Ontario's emissions in any given year, and a description is included of why the 'Draft Rules for Emission Trading in Ontario' rules do not meet these criteria. Permitting OPG to use its PERT credits to meet its Nox cap, will allow them to increase coal

All 131 Canadian medical graduates who completed FP training in 2011 to 2013 and who completed their undergraduate (UG) medical degree or postgraduate (PG) residency training or both at NOSM. Exposure to NOSM's medical education program at the UG (n = 49) or PG (n = 31) level or both (n = 51). Primary practice location in September of 2014. Approximately 16% (21 of 129) of FPs were practising in rural northern Ontario, 45% (58 of 129) in urban northern Ontario, and 5% (7 of 129) in rural southern Ontario. Logistic regression found that more rural Canadian background years predicted rural practice in northern Ontario or Ontario, with odds ratios of 1.16 and 1.12, respectively. Northern Canadian background, sex, marital status, and having children did not predict practice location. Completing both UG and PG training at NOSM predicted practising in rural and northern Ontario locations with odds ratios of 4.06 to 48.62. Approximately 61% (79 of 129) of Canadian medical graduate FPs who complete at least some of their training at NOSM practise in northern Ontario. Slightly more than a quarter (21 of 79) of these FPs practise in rural northern Ontario. The FPs with more years of rural background or those with greater exposure to NOSM's medical education programs had higher odds of practising in rural northern Ontario. This study shows that NOSM is on the road to reaching one of its social accountability milestones.

Latest investigations on atmospheric carbon tetrachloride (CTC) are focused on its ozone depleting potential, adverse effects on the human health, and radiative efficiency and Global Warming Potential as a greenhouse gas. CTC mixing ratios have been thoroughly studied since its restriction under the Montreal Protocol, mostly in remote areas with the aim of reporting long-term trends after its banning. The observed decrease of the CTC background mixing ratio, however, was not as strong as expected. In order to explain this behavior CTC lifetime should be adjusted by estimating the relative significance of its sinks and by identifying ongoing potential sources. Looking for possible sources, CTC was measured with high-time resolution in two sites in Northern Spain, using auto-GC systems and specifically developed acquisition and processing methodologies. The first site, Bilbao, is an urban area influenced by the surrounding industry, where measurements were performed with GC–MSD for a one-year period (2007–2008). The second site, at Valderejo Natural Park (VNP), is a rural background area where measurements were carried out with GC-FID and covering CTC data a nonsuccessive five-year period (2003–2005, 2010–2011, and 2014–2015 years). Median yearly CTC mixing ratios were slightly higher in the urban area (120 pptv) than in VNP (80–100 pptv). CTC was reported to be well mixed in the atmosphere and no sources were noticed to impact the rural site. The observed long-term trend in VNP was in agreement with the estimated global CTC emissions. In the urban site, apart from industrial and commercial CTC sources, chlorine-bleach products used as cleaning agents were reported as promotors of indoor sources. - Highlights: • A methodology was developed to measure CTC using GC-MSD and GC-FID. • CTC ongoing sources were noticed in an industry surrounded urban area. • No noticeable nearby CTC sources impacted the rural site. • Long-term CTC trend in agreement

Clinical guidelines and the fate of medical autonomy in Ontario.

Science.gov (United States)

Rappolt, S G

1997-04-01

Conceptually, clinical guidelines and professional autonomy have a paradoxical relationship. Despite being the quintessence of medical knowledge at the corporate level, guidelines diminish the clinical autonomy of individual practitioners, and therefore threaten medicine's justification for its autonomy. Theorists have argued that professional autonomy will be retained through elite dominance of practitioners, while comparative research suggests that economic autonomy can be traded off to retain clinical autonomy. Under government pressure to regulate the growth of Ontario physicians' fee-for-service public expenditure, the profession's representative organization, the Ontario Medical Association (OMA), promoted voluntary clinical guidelines, hoping to both constrain costs and preserve professional control over the content of medical care. The OMA collaborated with the Ministry of Health in developing guidelines and establishing a provincial centre for health service research. Ontario's practitioners disregarded the OMA's exhortations to implement clinical guidelines, suggesting that in the absence of external constraints, practitioners can subvert elite dominance. However, practitioners' unchecked clinical and economic autonomy, combined with evidence of wide provincial variations in medical care, served to legitimize the government's increasingly unilateral control over the schedule of insured medical services, and, in 1993, their imposition of a global cap on physicians' fee-for-service income pool. When analysed in the context of ongoing Ministry-OMA relations, the failure of the OMA's guidelines strategy to constrain medical service costs has expedited an overall decline in medical autonomy in Ontario. The emergence and course of Ontario's clinical guidelines movement is consistent with the view that medical autonomy is contingent upon broad class forces, and the conceptualization of professional organizations as instruments for mediated occupational control.

Three aerial radiological surveys were conducted during the period 16 June through 15 July 1986 over the towns of Pocatello, Soda Springs, and Fort Hall, Idaho and the surrounding areas. The surveys were performed for the United States Environmental Protection Agency (EPA) by the United States Department of Energy's (DOE) Remote Sensing Laboratory (RSL), utilizing the Aerial Measuring System (AMS). This work was completed in cooperation with a study by the EPA to conduct a dose assessment of human radiation exposure for industrial sources in Pocatello and Soda Springs, Idaho. The aerial surveys were performed to document the natural terrestrial radiological environment of the three localities and to map the spatial extent and degree of contamination due to phosphate milling operations. The results of these surveys will be used for planning ground-based measurements in addition to being incorporated into the dose assessment document. 4 refs., 14 figs., 6 tabs

Alternative pricing regimes in Ontario : exploring the impacts

International Nuclear Information System (INIS)

Rowlands, I.H.

2006-01-01

Legislative goals were recently established in Ontario to promote reliability and quality of electricity service and to ensure that distribution rates for customers remain reasonable. This presentation explored the effect of changing electricity pricing structures on residential customers in Ontario. This study investigated a period between May to December 2005, in the town of Milton, Ontario. Monthly demand was measured for each month, and monthly weighted averages were presented. Residents with electric heating were removed from the sample. Four pricing structure scenarios were examined: (1) flat rates; (2) time-of-use pricing regimes; (3) real time pricing regimes; and (4) critical peak pricing. Average monthly consumption rates for July and August for all 4 scenarios were presented. Results for time-of-use were compared to flat rates, which showed a slight increase in monthly costs. Real time average monthly electricity costs were significantly higher. Time-of-use costs increased by 57 per cent during the periods examined. Real time pricing regimes resulted in a 196 per cent rise in costs. It was concluded that more research must be done to explore the policy implications of pricing regimes and their effect on consumer behaviour. refs., tabs., figs

To determine the prevalence and diversity of Leptospira serogroups circulating in wildlife on farms in Ontario, we tested samples from 51 raccoons (Procyon lotor), seven skunks (Mephitis mephitis), four rats (Rattus norvegicus), and three opossums (Didelphis virginiana) that were trapped on 27 livestock (swine [Sus scrofa], cattle [Bos taurus]) farms in 2010. Seventeen of 51 raccoons (33%; 95% confidence interval [CI], 21-48%) sampled were positive for at least one Leptospira serogroup using the microscopic agglutination test. None of the other 14 animals had detectable Leptospira antibodies. On swine farms, 13 of 30 raccoons (43%; 95% CI, 27-61%) were antibody positive, and on cattle farms, four of 21 raccoons (19%; 95% CI, 8-40%) were positive. Leptospira antibody prevalence in raccoons did not differ between swine and cattle farms. Raccoons were positive to serovars representative of serogroups Grippotyphosa, Australis, Icterohaemorrhagiae, and Pomona and were negative to serovars of serogroups Autumnalis, Canicola, and Sejroe. The prevalence of Leptospira antibodies in raccoons in this study is similar to what has been reported previously; however, the diversity of serogroups was higher in this study than what has been reported in raccoons from an urban area of Ontario, Canada. Understanding the prevalence and distribution of Leptospira serogroups in wildlife in Ontario, Canada, is important for the development and maintenance of appropriate disease management strategies in humans, livestock, and companion animals.

Deregulation and the Alberta experience : the implications for Ontario

International Nuclear Information System (INIS)

Desrochers, J.P.

2002-01-01

An overview of the first year of electric power industry deregulation in Alberta was presented. The way in which electricity is bought and sold in Ontario and throughout North America is changing. Costs are no longer fixed and regulated. Electricity is becoming a commodity with high levels of price volatility. The paper presented hedging options for Alberta consumers, contracting lessons, market issues and lessons for Ontario. A comparison of Alberta's deregulation schedule with that of Ontario's was included. One year after market opening in Alberta, power prices have dropped significantly. There is a greater than expected demand side response, increased development in power generation, and a decrease in natural gas prices. Issues that still need to be addressed in Alberta include billing and load settlement issues, invoicing/billing standards, the lack of competition at the retail level, and future balancing of pool charges. Energy Advantage Inc. (EA) does not foresee the same drastic increase in price as seen in Alberta market opening, but suggests that uncertainty and volatility will exist in Ontario. In Alberta, customers who did nothing and stayed on default were the ones who benefited, but took a great risk. EA suggests that customers must understand how and when they use electricity, how much is used during on- and off-peak hours, and in the summer versus the winter. When electricity is priced hourly, it is important to know consumption patterns. 7 figs

Cancer mortality among immigrant populations in Ontario, 1969 through 1973.

OpenAIRE

Newman, A. M.; Spengler, R. F.

1984-01-01

Ontario is home to a sizeable, recently established immigrant population whose cancer mortality has until now remained unexamined. The province's six largest immigrant groups (British, Italian, German, Dutch, Polish and Soviet) were investigated to compare their cancer mortality experience with that prevailing in Ontario and in their countries of birth for the period 1969 through 1973. Standardized mortality ratios (SMRs) were computed from data from Statistics Canada and the World Health Org...

The potential vulnerability of the Namib and Nama Aquifers due to low recharge levels in the area surrounding the Naukluft Mountains, SW Namibia

Kambinda, Winnie N.; Mapani, Benjamin

2017-12-01

The Naukluft Mountains in the Namib Desert are a high rainfall-high discharge area. It sees increased stream-, spring-flow as well as waterfalls during the rainy season. The mountains are a major resource for additional recharge to the Namib and Nama aquifers that are adjacent to the mountains. This paper aimed to highlight the potential vulnerability of the aquifers that surround the Naukluft Mountain area; if the strategic importance of the Naukluft Karst Aquifer (NKA) for bulk water supply becomes necessary. Chloride Mass Balance Method (CMBM) was applied to estimate rainfall available for recharge as well as actual recharge thereof. This was applied using chloride concentration in precipitation, borehole and spring samples collected from the study area. Groundwater flow patterns were mapped from hydraulic head values. A 2D digital elevation model was developed using Arc-GIS. Results highlighted the influence of the NKA on regional groundwater flow. This paper found that groundwater flow was controlled by structural dip and elevation. Groundwater was observed to flow predominantly from the NKA to the south west towards the Namib Aquifer in two distinct flow patterns that separate at the center of the NKA. A distinct groundwater divide was defined between the two flow patterns. A minor flow pattern from the northern parts of the NKA to the north east towards the Nama Aquifer was validated. Due to the substantial water losses, the NKA is not a typical karst aquifer. While the project area receives an average rainfall of 170.36 mm/a, it was estimated that 1-14.24% (maximum 24.43 mm/a) rainfall was available for recharge to the NKA. Actual recharge to the NKA was estimated to be less than 1-18.21% (maximum 4.45 mm/a) reflecting the vast losses incurred by the NKA via discharge. This paper concluded that groundwater resources of the NKA were potentially finite. The possibility of developing the aquifer for bulk water supply would therefore drastically lower recharge

Ontario's energy crisis brings out conflicting visions

International Nuclear Information System (INIS)

Kishewitsch, S.

2004-01-01

Ontario's medium-term energy supply situation is discussed in light of the Ontario provincial government's insistence on phasing out coal-fired generation by 2007, and the somewhat longer term uncertainty about the aging nuclear fleet and the price tag associated with their overhauling or replacement. Centre to the discussion is the replacement of coal-fired plants by natural gas-fired generating plants, complicated by the fact is that there is already a surfeit of gas-fired plants sitting idle for lack of fuel available at an economically acceptable price. Recent statistics show that conventional gas supplies have already levelled off and unconventional sources, such as coalbed methane, and imports like LNG, are more abundant, but also significantly more expensive. The nuclear option is considered by knowledgeable insiders as a viable option for increased generation, although it is generally acknowledged as a serious public relations problem. The contributions of green power and cogeneration are also explored; the most optimistic estimates put the supply from this source at 50,000 GWh a year; less than the amount needed even in the absence of growth in demand. The overall conclusion is that Ontario's energy future can only be assured by aggressive pursuit of productivity improvements, financial and policy innovations, extensive use of cogeneration, strong development of renewables, energy conservation, efficiency, and demand management

Reappraisal of the seismotectonics of southern Ontario

Mohajer, A.A.

1987-11-01

The fundamental objectives of this study were to review and improve the seismological data base as an aid in more realistic evaluation of seismic hazard in southern Ontario. For this purpose, the following procedures have been undertaken: In the first stage, the types of errors in earthquake location files are identified, sources of uncertainties are discussed and a sensitivity analysis of the errors to different parameters is presented. In the second stage, a group location technique, Joint Hypocenter Determination (JHD), has been utilized to improve the locations of a group of 67 well-recorded events, mostly from the more active region near the Ottawa River and in western Quebec. The third stage, to relocate smaller and less reliably detected events in southern Ontario, utilized a nw algorithm, 'HYPOCENTER', which proved very efficient and flexible in the test runs for handling local explosion and natural events. A preliminary interpretation of the seismicity patterns in the study regions shows that earthquakes of magnitude 3 and larger tend to align along preferred seismic trends which may, in turn, be controlled by weakness planes in the Earth's crust. These inferred trends coincide with dominant northwesterly and northeasterly striking structural directions. For earthquakes smaller than magnitude 4 prior to 1970 and for microearthquakes (M<3) which occurred near the Lake Ontario shoreline, the detection coverage was not sufficient to conclusively discuss accurate locations and causative mechanisms

The Durham Strategic Energy Alliance : building a roadmap to meet Ontario's present and future energy needs

International Nuclear Information System (INIS)

Gabriel, K.; Lindeblom, D.

2006-01-01

The challenge facing Ontario in gaining access to affordable, flexible and reliable energy at a time when energy demand is escalating was discussed. The Durham Strategic Energy Alliance (DSEA) was created in 2005 to position Ontario's Durham Region as a Canadian leader in timely, sustainable and reliable energy solutions. Durham employs about 10,000 workers directly in the energy industry. The region also produces nearly 30 per cent of the province's power from local generating stations. It is also home to an energy focused teaching and research institution at the University of Ontario Institute of Technology. The DSEA is composed of business, industry, government and academic institutions committed to taking action on advancing energy solutions in all aspects of the energy life-cycle. Members have a stake in promoting sustainable energy solutions in energy supply and generation, manufacturing of energy solutions, transmission, distribution, conservation and/or consumption of all forms of energy. Since its creation, the DSEA has taken measures to exploit the energy opportunities in Durham Region and plans to significantly expand its activities in the future, particularly in building commercialization capabilities through an energy cluster. New links and formalized networks will be established to achieve this goal. Innovative networks will be developed to connect Durham's academic community with business, industry and energy clusters which are developing globally. The overall DSEA strategy is to develop Durham's energy cluster so that it evolves quickly into Ontario's energy commercialization center. There are three areas where such strategy will be recognized: energy technology adoption/demonstration centre; energy technology adoption officer; and, energy cluster outreach/network. 1 fig

The lithospheric structure beneath Ireland and surrounding areas from integrated geophysical-petrological modelling of magnetic and other geophysical data

Baykiev, E.; Guerri, M.; Fullea, J.

2017-12-01

The availability of unprecedented resolution aeromagnetic data in Ireland (Tellus project, http://www.tellus.ie/) in conjunction with new satellite magnetic data (e.g., ESÁs Swarm mission) has opened the possibility of detailed modelling of the Irish subsurface magnetic structure. A detailed knowledge of the magnetic characteristics (susceptibility, magnetite content) of the crust is relevant for a number of purposes, including geological mapping and mineral and geothermal energy prospection. In this work we model the magnetic structure of Ireland and surrounding areas using primarily aeromagnetic and satellite observations but also other geophysical data sets. To this aim we use a geophysical-petrological modelling tool (LitMod) in which key properties of rocks (i.e., density, electrical conductivity and seismic velocities) that can be inferred from geophysical data (gravity, seismic, EM) are self consistently determined based on the thermochemical conditions (using the software Perple_X). In contrast to the mantle, where thermodynamic equilibrium is prevalent, in the crust metastable conditions are dominant, i.e. rock properties may not be representative of the current, in situ, temperature and pressure conditions. Instead, the rock properties inferred from geophysical data may be reflecting the mineralogy stable at rock formation conditions. In addition, temperature plays a major role in the distribution of the long wavelength crustal magnetic anomalies. Magnetite retains its magnetic properties below its Curie temperature (585 ºC) and the depth of Curie's isotherm provides an estimate of the thickness of the magnetic crust. Hence, a precise knowledge of the crustal geotherm is required to consistently model crustal magnetic anomalies. In this work LitMod has been modified to account for metastable crustal lithology, to predict susceptibility in the areas below Curie's temperature, and to compute magnetic anomalies based on a magnetic tesseroid approach.

An experimental investigation of transient heat transfer in surrounding rock mass of high geothermal roadway

Directory of Open Access Journals (Sweden)

Zhang Yuan

2016-01-01

Full Text Available A self-designed experimental installation for transient heat transfer in the modelling surrounding rock mass of high geothermal roadways was elaborated in this paper. By utilizing the new installation, the temperature variation rules in surrounding rock mass of the high geothermal roadway during mechanical ventilation were studied. The results show that the roadway wall temperature decreases dramatically at the early stage of ventilation, and the temperature at every position of the surrounding rock mass is decreasing constantly with time passing by. From roadway wall to deep area, the temperature gradually increases until reaching original rock temperature. The relationship between dimensionless temperature and dimensionless radius demonstrates approximately exponential function. Meanwhile, the temperature disturbance range in the simulated surrounding rock mass extends gradually from the roadway wall to deep area in the surrounding rock mass. Besides, as the air velocity increases, heat loss in the surrounding rock mass rises and the ratio of temperature reduction becomes larger, the speed of disturbance range expansion also gets faster.

Can Culture Act as an Enabler to Innovation? Exploring the Germany-Ontario Experience Regarding the Introduction of Green Energy

Directory of Open Access Journals (Sweden)

Bill Irwin

2015-02-01

Full Text Available This paper explores the role that societal culture may play in terms of acting as an inhibitor or enabler when creating conditions conducive to innovative enterprise. To further understanding of this concept, the paper's authors explore different cultural influences and traditions of the country of Germany and the Canadian province of Ontario against the backdrop of the introduction of a government green energy policy and how local business reacts to new opportunities forthcoming from this shift in policy direction. The authors contend that the current Ontario psyche has contributed to an overall cultural drag on innovative activities. They demonstrate that in no place is this cultural impact more evident than the apparent lack of home-grown innovative activity surrounding green energy entrepreneurship; where, in spite of progressive and favourable provincial government policy, continued manufacturing growth is led by offshore companies The Ontario experience is in sharp contrast to current and historical German activity, when it comes to local innovation and advances in green energy. While Germany officially enacted their green energy act at the turn of the last century, experts agree that the German tenure with going green is in fact 35 to 40 years in the making. Although it has been contended that unique historical conditions such as postwar reconstruction and the reunification of the former East and West Germany have been significant contributing factors to Germany's embracing of sustainable energy, the authors of this paper contend that cultural factors such as the German sense of naturfreund; an overwhelming sense of being a nature-lover, may also play a significant role. In their exploration the authors build upon Hofstede's cultural dimension theory unpacking specific cultural components, as they compare actions and responses made by German and Ontarian policy-makers and business decision-makers.

Emissions trading in the context of electricity deregulation : a case study on Ontario

International Nuclear Information System (INIS)

Johns, G.

2003-01-01

This presentation discussed the deregulation of the electric power industry in Ontario and Alberta with particular reference to emissions trading, emissions profiles for the two provinces, and current market rules. It was noted that deregulation in Ontario is the major impetus for developing an emission trading system. Alberta is also in the process of developing an emission trading system for all industry sectors. The author discussed Ontario's Bill 210 which places a 6 year cap on prices and which offers tax incentives for renewable energy sources. It was argued that Bill 210 negates new generation and inhibits participants and competition in emissions trading market. Ontario generators face competitiveness concerns with neighbouring jurisdictions. Current market rules were outlined for emission caps, allocation for nitrogen oxide and sulfur dioxide allowances, credit creation, emission trading, and credit use. 6 figs

An aerial radiological survey of the Fort Calhoun Nuclear Power Plant and surrounding area, Fort Calhoun, Nebraska

International Nuclear Information System (INIS)

1994-05-01

An aerial radiological survey was conducted over the Fort Calhoun Nuclear Power Plant in Fort Calhoun, Nebraska, during the period June 19 through June 28, 1993. The survey was conducted at an altitude of 150 feet (46 meters) over a 25-square-mile (65-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Fort Calhoun Nuclear Power Plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 6 and 12 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and potassium. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey was conducted on August 9 and 10, 1972, before the plant began operation. Exposure rates measured in both surveys were consistent with normal terrestrial background

An aerial radiological survey was conducted from July 11--20, 1990, over an 83-square-kilometer (32-square-mile) area surrounding the Portsmouth Gaseous Diffusion Plant located near Portsmouth, Ohio. The survey was conducted at a nominal altitude of 91 meters (300 feet) with line spacings of 122 meters (400 feet). A contour map of the terrestrial gamma exposure rate extrapolated to 1 meter above ground level (AGL) was prepared and overlaid on an aerial photograph and a set of United States Geological Survey (USGS) topographic maps of the area. The terrestrial exposure rates varied from about 7 to 14 microroentgens per hour (μR/h) at 1 meter above the ground. Analysis of the data for man-made sources and for the uranium decay product, protactinium-234m ( 234m Pa), showed five sites within the boundaries of the Portsmouth Gaseous Diffusion Plant with elevated readings. Spectra obtained in the vicinity of the buildings at the Portsmouth Gaseous Diffusion Plant showed the presence of 234m Pa, a uranium-238 ( 238 U) decay product. In addition, spectral analysis of the data obtained over the processing plant facility showed gamma activity indicative of uranium-235 ( 234 U). No other man-made gamma ray emitting radioactive material was detected, either on or off the Portsmouth Gaseous Diffusion Plant property. Soil samples and pressurized ion chamber measurements were obtained at five different locations within the survey boundlaries to support the aerial data

An Outbreak of Foodborne Botulism in Ontario

Mona R Loutfy

2003-01-01

Full Text Available Botulism is a rare paralytic illness resulting from a potent neurotoxin produced by Clostridium botulinum. Botulism in Canada is predominately due to C botulinum type E and affects mainly the First Nations and Inuit populations. The most recent outbreak of botulism in Ontario was in Ottawa in 1991 and was caused by C botulinum type A. We report an outbreak of foodborne type B botulism in Ontario, which implicated home-canned tomatoes. The outbreak was characterized by mild symptoms in two cases and moderately severe illness in one case. The investigation shows the importance of considering the diagnosis of botulism in patients presenting with cranial nerve and autonomic dysfunction, especially when combined with gastrointestinal complaints; it also highlights the importance of proper home canning technique.

Independent Power Producers' view on restructuring in Ontario's electric power sector

International Nuclear Information System (INIS)

Brooks, J.

1996-01-01

The collective views on electricity industry restructuring of the independent power producers in Ontario were summarized by IPPSO's executive director. The Society is fully in agreement with the MacDonald Committee recommendations to privatize power generation in Ontario, and is equally in favor of competitive restructuring that is now underway in Michigan, New York and Quebec, as well as farther afield in the U.S., the U.K., and elsewhere around the world. IPPSO claims that a competitive generation system comprised of current and future IPPSO members could supply the province's power requirements at a cost 20 per cent lower than the present monopolistic system of Ontario Hydro. Add to that no reduction in services to the consumers, increased revenues in the form of taxes to the province, and the prospect of restructuring becomes far less threatening than first perceived. While fully in agreement with the MacDonald Committee's recommendations, IPPSO is opposed to Ontario Hydro's own restructuring plans. Their objection is based on the assessment that the plan would not result in real competition; in reality, it would allow Hydro even greater freedom to continue investing publicly-guaranteed money on a completely dissimilar basis to its competitors

Objective While newcomers are often disproportionately concentrated in disadvantaged areas, little attention is given to the effects of immigrants’ postimmigration context on their mental health and care use. Intersectionality theory suggests that understanding the full impact of disadvantage requires considering the effects of interacting factors. This study assessed the inter-relationship between recent immigration status, living in deprived areas and service use for non-psychotic mental health disorders. Study design Matched population-based cross-sectional study. Setting Ontario, Canada, where healthcare use data for 1999–2012 were linked to immigration data and area-based material deprivation scores. Participants Immigrants in urban Ontario, and their age-matched and sex-matched long-term residents (a group of Canadian-born or long-term immigrants, n=501 417 pairs). Primary and secondary outcome measures For immigrants and matched long-term residents, contact with primary care, psychiatric care and hospital care (emergency department visits or inpatient admissions) for non-psychotic mental health disorders was followed for 5 years and examined using conditional logistic regression models. Intersectionality was investigated by including a material deprivation quintile by immigrant status (immigrant vs long-term resident) interaction. Results Recent immigrants in urban Ontario were more likely than long-term residents to live in most deprived quintiles (immigrants—males: 22.8%, females: 22.3%; long-term residents—both sexes: 13.1%, pimmigrants than for long-term residents. Immigrants used less mental health services than long-term residents. Conclusions This study adds to existing research by suggesting that immigrant status and deprivation have a combined effect on recent immigrants’ care use for non-psychotic mental health disorders. In settings where immigrants are over-represented in deprived areas, policymakers focused on increasing

Ontario emissions trading code : emission reduction credit creation, recording and transfer rules, rules for renewable energy projects and conservation projects, and rules for the operation of the Ontario Emissions Trading Registry

International Nuclear Information System (INIS)

2001-12-01

Emissions trading has been an integral part of Ontario's air quality strategy since December 31, 2001. Ontario has adopted the 'cap, credit and trade' type of emissions trading system, a hybrid that takes the best features of pure 'cap-and-trade' and 'baseline-and-credit' type systems. It covers nitric oxide and sulphur dioxide. The Ontario Emissions Trading Code supplements Ontario Regulation 397/01 and sets out rules for renewable energy projects and conservation projects for which applications for emission allowances can be made. This Code describes the rules for the creation and transfer of emission reduction credits (ERCs). It also explains the rules for the operation of the registry that has been established to provide information to the public about the emissions trading program and records decisions about credit creation and credit and allowance retirement. 3 tabs

Coal-fired electricity generation in Ontario

International Nuclear Information System (INIS)

2001-03-01

This report examines coal-fired electricity generation in Ontario and recommends actions to be taken by the provincial government to protect the environment. The recommendations are also designed to assist in making decisions about the environmental safeguards needed for a competitive electricity industry. The report examines air emissions from coal-fired generating plants in the larger context of air pollution in the province; summarizes background information on key air pollutants; provides an individual profile of all coal-fired power stations in the province; and benchmarks Ontario's emissions performance by comparing it with 19 nearby U.S. jurisdictions. Current and proposed environmental controls for fossil fuel power generation in the province are elaborated. Options for maximizing environmental performance and the framework for strengthening environmental protection are reviewed. The report also contains a series of findings and recommendations which are deemed necessary before the moratorium imposed on the sale of coal-fired electricity plants imposed in May 2000, can be lifted. tabs., figs

Avian metapneumovirus subtype C in Wild Waterfowl in Ontario, Canada.

2018-02-18

Avian metapneumovirus (aMPV) is an emerging poultry pathogen that has a significant economic impact on poultry production worldwide. The geographic range of the virus continues to expand, and wild birds have been implicated as reservoirs of aMPV that have the potential to spread the virus over long distances. Our objective was to determine the apparent prevalence of aMPV subtype C in wild waterfowl in Ontario, Canada. Wild waterfowl were captured in August and September, 2016 as part of routine migratory waterfowl population monitoring by the Ontario Ministry of Natural Resources and Forestry. Oropharyngeal and cloacal swabs were collected from each bird and placed together for aMPV testing using real-time RT-PCR. A total of 374 live wild birds from 23 lakes were sampled and tested for aMPV. Among all ducks tested, 84 (22%) were positive for aMPV. The proportion of samples that tested positive ranged from 0% in ring-necked ducks (Aythya collaris) and green-winged teal (Anas carolinensis) to 44% (8 of 18) in American black ducks (A. rubripes). Waterfowl positive for aMPV were found at 14 of 23 lakes in the study area and the percent positive at these 14 lakes ranged between 5% and 84%. Although subtype C aMPV has been detected in a variety of wild birds in North America, this is the first report of aMPV in wild ducks in Ontario, Canada. The high apparent prevalence, particularly in mallards and American black ducks (37 and 44%, respectively), suggests that these species may be important reservoirs of aMPV. Given the potential impact of aMPV on domestic poultry and the potential role of wild birds as reservoirs of the virus, further investigation of the geographic distribution, risk factors associated with aMPV carriage in wild waterfowl and potential role of other birds in the epidemiology of aMPV in Canada is warranted. © 2018 Blackwell Verlag GmbH.

Physics education: Understanding the barriers for young women in Ontario

Science.gov (United States)

Mainhood, Lindsay Ann

In nearly all countries of the world, at every level of education, physics as a field of science is failing to recruit and retain women. This phenomenon is believed to relate to girls' educational experiences from K-12, but the reasons for the gender gap in physics are not fully understood. The purpose of this phenomenological research is to explore and understand the barriers encountered by Ontario female high school students during their physics education and the meanings attributed to those barriers by these young women. This research is guided by social cognitive career theory (SCCT) and uses the concept of physics identity as a lens through which the influence of contextual barriers can be understood. Nine participants, selected via snowball sampling from an Eastern Ontario university, together participated in four semi-structured focus group meetings and individually participated in a single in-depth, one-on-one interview. Audio data was transcribed verbatim and analyzed using a general inductive approach. Emergent themes are descriptively presented as the findings of the research study: perceiving the high school physics experience, experiencing high school physics education, and identity and gender in the high school physics experience. Sub-themes presented include limited prior experiences, negative perceptions of physics, images of physics learners, decision-making, reactions to pedagogy, learning needs, physics identity, gender-dependent influences, and making meaning of the experiences in high school physics. The shared experience of high school physics education for young women is understood as both a richly challenging and rewarding experience. Based on the findings of this research, recommendations are made for practical and research settings, and for future work in this area. Drawing on literature on underrepresentation of women in physics, this research contributes to the physics education research community and beyond; it offers voices of Ontario

1993-01-01

This study focused on the environmental impacts of fossil-fired generation that is expected to be displaced by electrical efficiency improvement programs and higher efficiency standards in the province on Ontario by the year 2000. Air emission dispersions were modelled by generating station. The impacts of air emission reductions on human mortality, human morbidity, building materials, agricultural crops, forests and lakes and fisheries were quantified using dose-response functions taken from the literature or estimated for the province of Ontario. Environmental impacts were monetized using cost data specific to Ontario. The final outcome was an estimate of the environmental benefits associated with emission reductions in fossil-fuelled power plants due to efficiency improvements in electricity use in the province of Ontario.

To determine the current distribution of ophthalmologists across Ontario's Local Health Integration Networks (LHINs) and the influence on LHIN-specific cataract surgery wait times. Cross-sectional study. Ophthalmologists listed in the College of Physicians and Surgeons (CPSO) database and the Canadian population. A list of ophthalmologists and their practice locations were obtained from the CPSO website. The total population count for Ontario was obtained from the Statistics Canada census. The population counts for the population aged 65 years and older were generated using the Canadian Socioeconomic Information Management System (CANSIM) table 109-5425. Cataract surgery wait times were obtained from the Ontario Ministry of Health. Statistical analysis was completed using Microsoft Excel using StatPlus software. There are currently 3.28 ophthalmologists per 100 000 total population in Ontario. LHIN-specific ratios ranged from 8.87 (Toronto Central) to 1.67 (Central West), with 3 out of 14 LHINs having met the previously recommended ratio of 3.37. Median cataract surgery wait times ranged from 30 to 72 days. Although the number of cataract surgeries performed was positively correlated with the population aged 65 years and older (p < 0.001), there was no statistically significant association between wait times and number of cataract cases per 1000 population (p = 0.41). Although Ontario appears to have a sufficient number of ophthalmologists overall, there is significant variation in the distribution of the ophthalmology workforce at the LHIN level. This variation did not appear to significantly influence LHIN-specific cataract surgery wait times. Copyright © 2016 Canadian Ophthalmological Society. Published by Elsevier Inc.

An assessment of the reliability of the Ontario electricity system : 18-month outlook from April 2004 to September 2005

International Nuclear Information System (INIS)

2004-01-01

This report presents a resource assessment by the Independent Electricity Market Operator (IMO) for the 18-month period from April 2004 to September 2005. It is based on the IMO's forecast of electricity demand. The information was provided by power generators in Ontario. The outlook for the electricity system has improved due to the return to service of 3 nuclear units and the addition of more than 700 MW of generation. The return to service of the nuclear units has decreased Ontario's reliance on imports to help meet energy demand in the province. The shutdown of 1150 MW of coal-fired generation at Lakeview Thermal Generating Station in Mississauga emphasizes the importance of improving transmission and generation capacity in the Toronto area. This report also includes updated values for existing resource scenarios and planned resource scenarios. The reliability of Ontario's transmission system was also assessed along with the adequacy of the existing resource to meet the forecast demand. The existing installed generation resources include 5 nuclear stations generating 10,831 MW of electricity, 5 coal stations generating 7,564 MW of electricity, 22 oil and gas fired stations generating 4,364 MW of electricity, 61 hydroelectric stations generating 7,676 MW of electricity, and 2 other stations generating 66 MW of electricity. Although the existing resource scenario is better than in previous reports, imports will be required under extreme weather conditions to help meet electricity demand in Ontario during peak periods. 21 tabs., 10 figs

Opportunities for independent power in Ontario : perspective of TransCanada Power

International Nuclear Information System (INIS)

Greflund, F.

1998-01-01

The recent white paper of the Government of Ontario and its implications for independent power producers (IPPs), vis-a-vis Ontario Hydro's market power and dominance, was discussed. The conclusion was that opportunities do exist to establish a competitive market for power which is open and transparent, has non-discriminatory transmission access, and in which price is a function of supply and demand. However, IPPs will need strong marketing skills to survive in the new marketplace. In addition to skills in power marketing, there will be strong demand for skills in gas marketing, operations, risk management, and financing. Prospects for interconnected markets and generators, and pipeline capacity considerations for Ontario were explored. The corporate profile of TransCanada Power (an affiliate of TransCanada Pipelines) was also reviewed. . 4 figs

Optometric labour market projections are provided. First, population growth and ageing-based estimates of the rate of increase of eye-care services in Ontario from 2011 to 2$ are presented, holding the age-sex structure of utilization constant. Then, using data on the 2011 supply and working hours of Ontario's optometrists, the number of optometrists needed to keep the level of optometric services per age-sex-adjusted person comparable over time is estimated. The projections suggest that the number of Ontario optometrists should grow by approximately 30-40 full-time equivalents per year; to offset retirements and account for decreasing work hours, this suggests 77-90 new practitioners are required each year. However, in recent years, the number of Ontario optometrists has been growing faster than this, suggesting either that demand has exceeded supply and/or surpluses will accumulate if this trend continues.

Dahlstrom, T.S.

1988-02-01

An aerial radiological survey was conducted during the period 24 July through 2 August 1986 over a 124-square-kilometer (48-square-mile) area surrounding the Trojan Nuclear Plant located on the Columbia River at Prescott, Oregon. The survey was conducted at a nominal altitude of 46 meters (150 feet) with line spacings of 76 meters (250 feet). Count rates were converted to exposure rates at 1 meter above the ground. A contour map of the terrestrial gamma exposure rate was prepared and overlaid on a USGS topographic map of the area. The exposure rates varied from 8 to 10 microroentgens per hour (μRh) in the southern and northernmost regions of the survey area with somewhat lesser rates of 6.5 to 8.0 μRh in the immediate vicinity of LongviewKelso, Washington. The highest area of increased activity was directly attributed to the main units of the plant and indicated the presence of 60 Co and 58 Co. Soil samples and ion chamber measurements were obtained at four locations to support the aerial data. An additional 11 soil samples were collected along the shoreline of the Columbia River. 6 refs., 11 figs., 4 tabs

Section 60 revisited (The Ontario Electrical Safety Code)

Energy Technology Data Exchange (ETDEWEB)

Olechna, T.

2003-06-01

Recent changes to the Ontario Electrical Safety Code (OESC), specifically the deletion of Section 60, Electrical Communication Systems, are discussed in an effort to explain the history behind the decision and the time frame of the changes. Communication systems include telephone, telegraph, data communications, intercommunications, wired music and paging systems. In brief, the deletion of Section 60 occurred in 1983, and resulted from the fact that communication-type wiring was historically the property of the communications utility and under federal jurisdiction. Since such equipment was under federal jurisdiction, they were not inspected in Ontario, hence the deletion of Section 60 from the Ontario Code. It should be noted that although Section 60 is deleted, a number of rules applicable to communications circuits are spread throughout various sections of the Code, notably in Rule 1-032 dealing with damage and interference, Rule 4-022 involving harmonics issues, Rule 12-904(2) regulates the use of conductors that are of different sources of voltage, and Rule 10-708 which specifies the spacing and bonding requirements for communications systems. The end result is that even though Section 60 was deleted, there are these and other rules in the OESC that have direct impact on communications circuits and in effect help to protect the integrity of the system.

2005-05-15

Details of the Ontario Tire Recycling and Economic Development (OnTRED) plan were presented. The plan was developed to address deficiencies in the Ontario Tire Stewardship's (OTS) Scrap Tire Diversion Program plan. The OTS promotes the burning of scrap tires contrary to the Waste Diversion Act, and transfers the financial responsibility for scrap tire management from manufacturers to retailers. The OnTRED plan will attempt to improve the current 87 per cent recovery rate for passenger scrap tires in Ontario, and prevent the formation of any new tire stockpiles. The aim of the OnTRED plan is to ensure reuse and recycling consistent with provisions in the Waste Diversion Act and enhance the existing workings of the tire and scrap tire market through the promotion of reuse and recycling. In addition, the plan aims to minimize administration and compliance costs. A program summary of the OnTRED plan was presented, as well as details of market development plans and buy-recycled rebates. Issues concerning collector registration and transaction tracking were presented, as well as details of brand-owner and first importer pay-in models. Stakeholder roles and responsibilities were reviewed. A budget scenario was presented, as well as a rebate and diversion scenario. It was concluded that Ontario's 87 per cent scrap tire diversion rate can be improved through a focus on patterns of reuse and recycling. 3 tabs., 7 figs.

Full Text Available The objectives of this research are: (1 to study the characteristics of aquifer, distribution and chemical types of groundwater in the research area; (2 to measure the consentration of major elements (HC03-, Cl-, S042-, Ca2+, Mg2+, Na+, K+ and minor elements (S2-, NH4+ as indicators of leached contamination in the groundwater; and (3 to establish the spreading of contamined groundwater by leached. The grid sampling method was applied in this research. The grid dimension is 1 cm x 1 cm measured in the 1:25000 scale of Indonesian Topographic Map. The groundwater samples were taken randomly within the grid. Not the whole study area covered by the map was grided but only the surrounding area of Piyungan Landfill and the area lower than Piyungan landfill were grided. The groundwater samples were taken during the rainy season because during the rainy season there were more leached produced from Piyungan Landfill. The groundwater samples were examined their physical and chemical qualities using the legal standard quality in Yogyakarta Province. Spatial analysis using maps and graphics were applied to examine the spreading of contimined groundwater by leached. The spreading of unconfined groundwater in the study area was not equal distributed but it seems to be controlled by the landforms. There were an increasing elements content of Cl-, Ca2+, Mg2+ and HCO3-, as well as dissolved oxygen, NO3- and S2- in the groundwater contamined by leached. The zonation of the spreading of groundwater contamined by leached was categorized into three class, i.e., central (location of landfill, well number 1 0, transisional (well number: 11, 12, 13, 15, and primary (well number: 8, 14, 16, 17, 25, 26 zones. The zonation of groundwater matched with the analysis of groundwater quality by the distance from the Piyungan Landfill.

Ontario Energy Board : 2000-2001 annual report

Energy Technology Data Exchange (ETDEWEB)

NONE

2001-10-01

Fiscal 2000-2001 was a busy period for the Ontario Energy Board (OEB) as it was preparing for Ontario's new, competitive electricity market. The OEB's roles and responsibilities have been changing in recent years in preparation for more administrative responsibilities in the deregulated electricity market. In 2000, the OEB distributed a proposed gas distribution access rule for comment by industry and other stakeholders. Another major highlight of the year's work was the development of the 2000 Model Gas Franchise Agreement. The OEB also assumed a leadership role in the electricity sector to ensure the readiness of retail participants in Ontario's competitive electricity market. The Market Readiness Task Force was instrumental in this activity. This Task Force was led by the Independent Electricity Market Operator. Various rules, codes, handbooks and guidelines were also developed, based on the advise of various stakeholders. The Board also continued its work to improve the efficiency of its regulatory procedures and processes by encouraging electronic business transactions and paperless hearings. These efficient ways of doing business should contribute to the cost-effectiveness of the Board. In 2000 the Board began its review of the first unbundled rate applications from electricity distributors and approved 69 out of 114 applications for mergers and acquisition in the electricity sector. The customary consolidated financial statement including balance sheets, assets, liabilities and capital were also included in this report. tabs., figs.

1985-03-01

An aerial radiological survey was conducted over the area surrounding the Diablo Canyon Nuclear Power Plant in Diablo Canyon, California. The survey was conducted between 20 September and 3 October 1984. A series of flight lines parallel to the coastline were flown at an altitude of 91 meters (300 feet) and were spaced 152 meters (500 feet) apart. The survey covered an area of 250 square kilometers (100 square miles). The resulting background exposure rates over the survey area ranged from 5 to 21 microroentgens per hour (μR/h). The reported exposure rate values include an estimated cosmics ray contribution of 3.6 μR/h. Soil samples were also collected at several locations within the survey areas and analyzed in the laboratory for isotopic composition. The results of the survey showed only the presence of naturally occurring background radiation. No man-made radioactivity was detected. 4 refs., 4 figs., 4 tabs

Ultrasonic inspection experience of steam generator tubes at Ontario Hydro and the TRUSTIE inspection system

International Nuclear Information System (INIS)

Choi, E.I.; Jansen, D.

1998-01-01

Ontario Hydro have been using ultrasonic test (UT) technique to inspect steam generator (SG) tubes since 1993. The UT technique has higher sensitivity in detecting flaws in SG tubes and can characterize the flaws with higher accuracy. Although an outside contractor was used initially, Ontario Hydro has been using a self-developed system since 1995. The TRUSTIE system (Tiny Rotating UltraSonic Tube Inspection Equipment) was developed by Ontario Hydro Technologies specifically for 12.7 mm outside diameter (OD) tubes, and later expanded to larger tubes. To date TRUSTIE has been used in all of Ontario Hydro's nuclear generating stations inspecting for flaws such as pitting, denting, and cracks at top-of-tubesheet to the U-bend region. (author)

Full Text Available Two summers' field surveys at 9 locations in northwestern Ontario showed that woodland caribou (Rangifer tarandus caribou wintering areas supported jack pine and black spruce stands with low tree densities (mean 1552 trees/ ha, 39% of a fully stocked stand, low basal areas (mean 14.14 m2/ha, low volumes (mean 116 mVha, 68% of Normal Yield Tables and short heights (95% of stands 12 m or less. Ecologically, most sights were classed V30. Significantly more lichen (averaging 39% lichen ground cover was found on plots used by caribou. Three measured areas showed few shrubs, possibly enhancing escape possibilities and reducing browse attractive to moose. An HIS model predicted known locations of caribou winter habitat from FRI data with 76% accuracy. Landsat imagery theme 3 (open conifer produced 74% accuracy. Combining these methods permitted prediction of all 50 test sites. The low volumes of timber found in caribou wintering areas suggest that setting aside reserves for caribou winter habitat would not sacrifice as much wood product value as might at first appear.

A set of three maps show surficial geology, significant unconsolidated aquifers and well yield, and selected well locations for the Lake Ontario basin, New York. In the low areas , glaciers and wave action of former high-level lakes deposited permeable sand and gravel to form aquifers that yield more than 10 gal/min of water to wells. Small quantities of water (less than 2 gal/min) can be pumped from dug wells that top till and fine lake-sediment deposits. (USGS)

Particulate organic compounds in the atmosphere surrounding an industrialised area of Prato (Italy)

Cincinelli, Alessandra; Mandorlo, Stefano; Dickhut, Rebecca M.; Lepri, Luciano

Atmospheric aerosols were collected during the period from May 2000 through January 2001 at 13 different sites in and around the Baciacavallo sewage treatment plant in Prato (Italy). The urban area surrounding the plant contains significant textile industrial activity and a main arterial road. Aerosol-associated n-alkane, polycyclic aromatic hydrocarbon (PAH), nonylphenol (NP) and nonylphenolethoxylate (NPnEO) ( n=1-3) concentrations were measured in order to evaluate contributions from the sewage treatment plant, naturally produced aerosols, transportation and industrial activities to the air quality in the vicinity of the sewage treatment plant. Aerosol-associated n-alkane concentrations ranged from 36.7 to 205 ng/m 3 and their possible origin was determined by the presence of typical petroleum characteristics such as the unresolved complex mixture and an odd/even carbon ratio (Carbon Preference Index). PAH concentrations ranged from 0.855 to 24.2 ng/m 3, in accordance with those generally found for urban aerosols in Europe. NP and NPnEO ( n=1-3), as well as fine aerosol particulate matter (PM 10) were significantly correlated with relative wind direction with increased levels observed in the ambient atmosphere when the relative wind direction was from the Baciacavallo sewage treatment plant. This study confirms the use of NP and NPnEO ( n=1-3) as markers of sewage treatment emissions and the importance of the contribution of aerosols produced by sewage treatment plant aeration tanks to the local atmospheric composition.

2018-01-01

The purpose of this study was to compare the prevalence of self-reported mental health factors, mental health service use, and unmet needs across the 4 largest ethnic groups in Ontario, Canada: white, South Asian, Chinese, and black groups. The study population was derived from the Canadian Community Health Survey, using a cross-sectional sample of 254,951 white, South Asian, Chinese, and black residents living in Ontario, Canada, between 2001 and 2014. Age- and sex-standardized prevalence estimates for mental health factors, mental health service use, and unmet needs were calculated for each of the 4 ethnic groups overall and by sociodemographic characteristics. We found that self-reported physician-diagnosed mood and anxiety disorders and mental health service use were generally lower among South Asian, Chinese, and black respondents compared to white respondents. Chinese individuals reported the weakest sense of belonging to their local community and the poorest self-rated mental health and were nearly as likely to report suicidal thoughts in the past year as white respondents. Among those self-reporting fair or poor mental health, less than half sought help from a mental health professional, ranging from only 19.8% in the Chinese group to 50.8% in the white group. The prevalence of mental health factors and mental health service use varied widely across ethnic groups. Efforts are needed to better understand and address cultural and system-level barriers surrounding high unmet needs and to identify ethnically tailored and culturally appropriate clinical supports and practices to ensure equitable and timely mental health care.

Gaboury, J.

2001-01-01

The focus of this presentation was on the generation and sale of electricity. Prior to deregulation, companies that generated electricity had a readily available customer base to whom the electricity could be sold. The author discussed some of the changes affecting the industry as a result of deregulation of the electricity market in Ontario: the increasing number of companies, as well as the increased number of generators supplying power within the province. Currently 85 per cent of the generation in Ontario is met by Ontario Power Generation (OPG) and this percentage will decrease through de-control. De-control can be achieved in a variety of ways, either through the sale of assets, leases, asset swaps. The market rules dictate that OPG not control in excess of 35 per cent of the generation supply in Ontario, OPG is examining the situation. New supply being constructed or new interconnections with neighboring markets could affect the total assets that would have to be de-controlled. OPG has a mix of generation that includes hydroelectric, fossil, and nuclear, as well as a single wind turbine. Green power, defined as electricity generation deemed less intrusive environmentally than most traditional generation, includes wind, water, landfill gas, solar and others, and could affect the mix of generation. It is expected that there will be a niche market for green power, especially when one considers the reduction in emissions. It could represent a viable option for smaller startup companies, as less capital is required. The options for selling the power, either to the spot market or by entering into a bilateral contract with another customer, were explained

1979-04-01

This report derives three estimates of long-term nuclear growth in Ontario for use in strategy studies of alternate nuclear fuel cycles. The low and high estimates encompass the full range of possible long-term nuclear growth rates. The middle, or base growth, estimate represents the nuclear growth pattern which seems at the present time most likely to occur. For the base growth estimate, nuclear capacity in Ontario reaches 31 GWe in 2000, grows to 175 GWe by 2060, and then remains constant. For the high growth estimate, the capacity in 2000 is 33 GWe, and climbs continuously to 833 GWe by the year 2100. (auth)

Delineating demographic units of woodland caribou (Rangifer tarandus caribou in Ontario: cautions and insights

Directory of Open Access Journals (Sweden)

Jennifer L. Shuter

2012-03-01

Full Text Available Delineating demographic structure across an organism’s range can reveal the extent to which population dynamics in different geographic areas are driven by local or external factors and can be crucial for effective conservation and management. Obtaining optimal data for such analyses can be time and resource-intensive and impending development and resource extraction pressures may necessitate the examination of existing data, even when they are less than ideal. We analyzed a historic telemetry dataset containing satellite radio-collar locations of 73 forest-dwelling woodland caribou in northern Ontario to determine demographic structure. We applied several clustering methods (i.e., agglomerative, divisive and fuzzy k-means to median seasonal locations. Results were used to distinguish demographic units and minimum convex polygons and fixed-kernel density estimates were used to delineate unit boundaries and core areas. For areas where sampling was considered representative of the distribution of caribou on the landscape, we assessed demographic distinctness by evaluating intra-individual variation in cluster membership, membership strength and distance between boundaries and core areas of adjacent units. The number and composition of clusters identified was similar among methods and caribou were grouped into 6 general clusters. The distinctions between the three clusters identified in the central portion of the province (i.e., Lac Seul, Wabakimi, Geraldton and the two clusters identified in the eastern portion of the province (i.e., Cochrane and Cochrane-Quebec were determined to represent demographic structuring. Additional distinctions in other areas (i.e., between The Red Lake and Lac Seul clusters in the west and between the central and eastern clusters may just be artifacts of the original sampling effort. Amongst demographic units, there was no evidence of individual flexibility in cluster membership and average membership strength was

2001-03-01

This document informs electric power market participants of the Ontario Energy Board's newly developed market readiness plan and target timelines that local distribution companies (LDCs) must meet for retail marketing. The Ontario Energy Board's plan incorporates relevant independent market operator (IMO)-administered market milestones with retail market readiness targeted for September 2001. The market readiness framework involves a self-certification process for LDCs by August 10, 2001, through which the Board will be able to monitor progress and assess the feasibility of meeting the target timelines. For retail market readiness, all LDCs will have to calculate settlement costs, produce unbundled bills, provide standard supply service, change suppliers and accommodate retail transactions. LDCs must be either authorized participants in the IMO-administered market or become retail customers of their host LDC. Unbundled bills will include itemized charges for energy price, transmission, distribution and debt retirement charge. 1 tab., 1 fig

Towards a Caribou Habitat Management Strategy for Northwestern Ontario: Running the Gauntlet

Directory of Open Access Journals (Sweden)

Gerald D. Racey

1996-01-01

Full Text Available A management strategy for woodland caribou (Rangifer tarandus caribou habitat is being developed in northwestern Ontario. This strategy is based upon a set of draft Timber Management Guidelines for the Provision of Woodland Caribou Habitat. These guidelines recommend maintaining a sustainable supply of winter habitat within large tracts of old forest, protecting calving areas and minimizing human disturbance. Due to the large temporal and spatial scale of caribou habitat management, an ecosystem-based approach is recommended. Public response to the strategy shows a strong dichotomy between environmental and utilitarian values among all the major stakeholder groups. The major issues raised by the public include security of industrial wood supply, quality of the knowledge base, level of awareness of caribou, economic impacts on remote communities, concern about environmental impacts and silvicultural know-how. The government is responding to these concerns as the strategy evolves. Current emphasis is placed on increasing awareness of the public, training resource managers in caribou biology, management and habitat planning, implementing interim habitat management prescriptions and studying the potential impact on wood supply. The final direction for a northwestern Ontario strategy to conserve woodland caribou habitat has yet to be decided, although a commitment has been made to strive for the conservation of woodland caribou populations and their habitat.

The impact of the Market Power Mitigation Agreement on power prices in Ontario

International Nuclear Information System (INIS)

Chute, R. G.

2000-01-01

Market power was defined by the Market Design Committee (MDC) as 'the ability to sustain a significant price increase profitably', although it is generally understood to refer to the 'overwhelming dominance of generating capacity and supply capability of Ontario Power Generation' (OPG), the former generating arm of Ontario Hydro. The MDC sought to address market power within the context of the Ontario Government's White Paper on electricity sector reform, entitled 'Directions for Change'. The solution was the Market Power Mitigation Agreement (MPMA), a negotiated agreement between the MDC and OPG that established market share goals and provided incentives and penalties to meet these goals. Briefly, the major instrument used by the MPMA is the price of electric power sold in the Ontario market to reward, or penalize the actions of OPG in moving towards its market share goals as defined in the MPMA. This paper explains the principal elements of the MPMA and how they are expected to influence the market prices for power in Ontario. The principal elements of the Agreement are price cap and rebate, decontrol targets, and intertie capacity and limits, while the instruments comprise licence conditions, settlement agreements, market rules and ministerial directives. The issue of the impact of the MPMA on the cost of power, and the future prospects of market power after the expiration of the MPMA are also addressed

Electricity deregulation roundup : Ontario prepares for electricity deregulation and anxiously watches impact elsewhere

Hurst, R.

2000-01-01

As the time for deregulation of Ontario's electric power industry approaches, consumers are watching other Canadian and American jurisdictions to see what deregulation will mean in terms of energy costs. Albertans have expressed serious concerns about the impact of deregulating their electric power industry. They found that in the four years since deregulation in their province, electricity prices increased when markets opened to competition. The proposed start date for deregulation in Ontario is November 1, 2000. This paper suggests that if investors don't put out significant resources, problems such as power shortages and brownouts could occur, as was the case in Alberta. Potential investors in the Ontario electricity market are already sceptical because the Ontario government, in an effort to protect consumers from unreasonable price increases, has tabled legislation that restricts the efforts of municipal utility companies to raise distribution rates. One step that will inspire some confidence is the recently finalized deal between Ontario Power Generation and British Energy to operate the Bruce Nuclear Power Station. Independent consultants have warned that electricity prices will continue to increase with deregulation for a least the next few years. Industrial customers will be the hardest hit. In California, America's first deregulated electricity market, the power grid is strained and prices have doubled or tripled in one year

Market readiness report : status of preparation for Ontario's competitive retail electricity market

International Nuclear Information System (INIS)

2002-01-01

The Ontario Energy Board (OEB) assumes a leadership role in the electricity sector to ensure the readiness of retail participants in Ontario's competitive electricity market. The Market Readiness Project Team is instrumental in this activity. The team, led by the Independent Electricity Market Operator, provides information and advice regarding the technical readiness of the retail industry, with particular focus on the readiness of distributors to carry out their important functions in a competitive market. This report provides an assessment of the team regarding the industry's technical readiness based on information as of December 14, 2001. The status of retail market readiness was reviewed in terms of the viability of the design of the new competitive market and on the status of Ontario distributors in enabling a competitive market. The workplan for the remaining industry activities needed to achieve market opening were then summarized along with the contingency arrangements for any distributors that are not ready for market opening. Based on several projections, an estimated 88 per cent of Ontario contracts will be served by a distributor starting on a May 1, 2002 market opening. tabs., figs., appendices

Ontario electricity bill review

International Nuclear Information System (INIS)

O'Neill, G.

2003-01-01

Findings of an independent review of charges to electricity bills and recommendations to assist in the development of a standard, province-wide residential electricity bill for Ontario are discussed. The review was requested by the province's Minister of Energy in an effort to dispel growing confusion about the variations in customer billing practices used by the province's 90+ local distribution companies. Key recommendations and findings were as follows: (1)Consumer bill formats issued by local distribution companies should be more consumer-friendly, adhere to minimum design standards, adapt uniform terminology and common line charges; (2) charges on customer bills should be grouped into four standard line items, with full details available to customers: the four line items should be a basic service charge, a charge for delivering electricity to the customer, a charge for the electricity itself, and a separate charge for retiring the outstanding debt of the former Ontario Hydro; (3) bills should take advantage of opportunities for promoting province-wide energy conservation, such as encouraging the long-term use of interval meters, presenting historical consumption data on residential bills on a period-to-period basis, and education and communications initiatives. Details of the recommendations, including the calculation of the fixed and variable components of usage charges, an explanation of the concept of electricity system loss adjustments, a method for phasing in the recommendations, and the anticipated benefits to consumers are provided

One of the greatest challenges facing modern society is rapid climate change resulting from greenhouse gases emissions to the atmosphere, primarily in the form of carbon dioxide from the burning of fossil fuels. The effects of climate change on natural environments will inevitably affect people as well, if left unchanged. In addition to many other societal benefits, forests store large amounts of carbon. As a result, it is necessary to understand how forest management and natural processes affect forest carbon storage. Such information can be utilized to manage forests so that they function as carbon sinks and help reduce greenhouse gas concentrations in the atmosphere. This report employed data about Ontario's forest structure and information from the forest management planning process and past harvests to describe carbon in forests and wood products today and through to the end of this century. The paper described the methods used for the study which included modification of the United States national forest carbon model, FORCARB2, to predict Ontario's forest carbon budgets in order to make carbon projections congruent with forest management plans. The modified forest carbon model, which is called FORCARB-ON, predicts carbon in live trees, understory vegetation, forest floor, standing and down dead wood, and soil. Ontario's managed forests are projected to increase carbon storage by 433 million tonnes from 2000 to 2100. The largest forest sink will be in wood products, accounting for 364 million tonnes of carbon storage over the century. 22 refs., 1 tab., 3 figs

Economic impacts of the solar PV sector in Ontario 2008-2018

International Nuclear Information System (INIS)

2011-07-01

Over the next 20 years most of the electricity generating facilities in Ontario will need to be replaced or refurbished and the electricity demand will rise by 15%. The province has adopted a long term energy plan (LTEP) to prepare for these changes; its objectives are to reduce demand and to produce electricity from nuclear power and renewable energy sources by 2030. The LTEP foresees the installation of 3,000 MW solar photovoltaic (PV) energy by 2018 in Ontario and the aim of this report is to determine the economic effects of this development on investments, job creation and cost to customers. Over 150 interviews and 100 surveys were carried out with solar PV stakeholders. It was found that the solar PV market in Ontario will drive $13 billion of private investment, create 74,000 jobs at a cost of $5 per month to electricity customers by 2018.

Infectious diseases in farmed animals have economic, social, and health consequences. Foreign animal diseases (FAD) of swine are of significant concern. Mathematical and simulation models are often used to simulate FAD outbreaks and best practices for control. However, simulation outcomes are sensitive to the population structure used. Within Canada, access to individual swine farm population data with which to parameterize models is a challenge because of privacy concerns. Our objective was to develop a methodology to model the farmed swine population in Ontario, Canada that could represent the existing population structure and improve the efficacy of simulation models. We developed a swine population model based on the factors such as facilities supporting farm infrastructure, land availability, zoning and local regulations, and natural geographic barriers that could affect swine farming in Ontario. Assigned farm locations were equal to the swine farm density described in the 2011 Canadian Census of Agriculture. Farms were then randomly assigned to farm types proportional to the existing swine herd types. We compared the swine population models with a known database of swine farm locations in Ontario and found that the modeled population was representative of farm locations with a high accuracy (AUC: 0.91, Standard deviation: 0.02) suggesting that our algorithm generated a reasonable approximation of farm locations in Ontario. In the absence of a readily accessible dataset providing details of the relative locations of swine farms in Ontario, development of a model livestock population that captures key characteristics of the true population structure while protecting privacy concerns is an important methodological advancement. This methodology will be useful for individuals interested in modeling the spread of pathogens between farms across a landscape and using these models to evaluate disease control strategies.

Green power opportunities for Ontario

International Nuclear Information System (INIS)

Elwell, C.; Rotenberg, E.; Torrie, R.; Poch, D.; Allen, G.

2002-02-01

Green energy is defined as the energy generated from renewable and environmentally benign sources. In this document, the authors demonstrated that Ontario possesses the potential to reduce energy waste on an economic basis while generating sufficient green energy to enable the province to decommission its coal burning power plants. In turn, this would lead to a more sustainable energy economy and a lesser reliance on nuclear generation. It was determined that a three-fold policy would enable the province to achieve this goal. First, there is a need to remove hidden subsidies to polluting forms of generation. The second aspect of this policy is the implementation of a robust Demand Side Management Program, and the third aspect calls for the reform of the price of electricity that includes all costs. In this manner, all forms of generation would compete on an equal footing. The authors identified an alternative to immediate price reform in the form of a legislated Renewable Portfolio Standard. A growing percentage of new renewable electricity in the supply portfolio offered by electricity providers would be required by the Renewable Portfolio Standard. It was suggested that the Ontario government adopt this measure before the opening of the electricity market in May 2002, as strong support for the measure is present. 13 refs

Source Water Protection Planning for Ontario First Nations Communities: Case Studies Identifying Challenges and Outcomes

Directory of Open Access Journals (Sweden)

Leslie Collins

2017-07-01

Full Text Available After the Walkerton tragedy in 2000, where drinking water contamination left seven people dead and many suffering from chronic illness, the Province of Ontario, Canada implemented policies to develop Source Water Protection (SWP plans. Under the Clean Water Act (2006, thirty-six regional Conservation Authorities were mandated to develop watershed-based SWP plans under 19 Source Protection Regions. Most First Nations in Ontario are outside of these Source Protection Regions and reserve lands are under Federal jurisdiction. This paper explores how First Nations in Ontario are attempting to address SWP to improve drinking water quality in their communities even though these communities are not part of the Ontario SWP framework. The case studies highlight the gap between the regulatory requirements of the Federal and Provincial governments and the challenges for First Nations in Ontario from lack of funding to implement solutions to address the threats identified in SWP planning. This analysis of different approaches taken by Ontario First Nations shows that the Ontario framework for SWP planning is not an option for the majority of First Nations communities, and does not adequately address threats originating on reserve lands. First Nations attempting to address on-reserve threats to drinking water are using a variety of resources and approaches to develop community SWP plans. However, a common theme of all the cases surveyed is a lack of funding to support implementing solutions for the threats identified by the SWP planning process. Federal government initiatives to address the chronic problem of boil water advisories within Indigenous communities do not recognize SWP planning as a cost-effective tool for improving drinking water quality.

Geospatial Estimates of Road Salt Usage Across a Gradient of Urbanizing Watersheds in Southern Ontario:Thesis for Masters in Spatial Analysis (MSA)

Science.gov (United States)

Giberson, G. K.; Oswald, C.

2015-12-01

In areas affected by snow, chloride (Cl) salts are widely used as a de-icing agent to improve road conditions. While the improvement in road safety is indisputable, there are environmental consequences to local aquatic ecosystems. In many waterways, Cl concentrations have been increasing since the early 1990s, often exceeding national water quality guidelines. To determine the quantity of Cl that is accumulating in urban and urbanizing watersheds, accurate estimates of road salt usage at the watershed-scale are needed. The complex jurisdictional control over road salt application in southern Ontario lends itself to a geospatial approach for calculating Cl inputs to improve the accuracy of watershed-scale Cl mass balance estimates. This study will develop a geospatial protocol for combining information on road salt applications and road network areas to refine watershed-scale Cl inputs, as well as assess spatiotemporal patterns in road salt application across the southern Ontario study region. The overall objective of this project is to use geospatial methods (predominantly ArcGIS) to develop high-accuracy estimates of road salt usage in urbanizing watersheds in southern Ontario. Specifically, the aims will be to map and summarize the types and areas ("lane-lengths") of roadways in each watershed that have road salt applied to them, to determine the most appropriate source(s) of road salt usage data for each watershed, taking into consideration multiple levels of jurisdiction (e.g. municipal, regional, provincial), to calculate and summarize sub-watershed and watershed-scale road salt usage estimates for multiple years, and to analyze intra-watershed spatiotemporal patterns of road salt usage, especially focusing on impervious surfaces. These analyses will recommend areas of concern exacerbated by high-levels of road salt distribution; recommendations around modifying on-the-ground operations will be the next step in helping to correct these issues.

The Council of Ontario University Programs in Nursing offers a nine-university, consortium-based primary health care nurse practitioner education program and on-line continuing education courses for primary health care nurse practitioners. Our study sought to determine the continuing education needs of primary health care nurse practitioners across Ontario, how best to meet these needs, and the barriers they face in completing continuing education. Surveys were completed by 83 (40%) of 209 learners who had participated in continuing education offered by the Council of Ontario University Programs in Nursing between 2004 and 2007. While 83% (n=50) of nurse practitioners surveyed indicated that continuing education was extremely important to them, they also identified barriers to engaging in continuing education offerings including; time intensity of the courses, difficulty taking time off work, family obligations, finances and fatigue. The most common reason for withdrawal from a continuing education offering was the difficulty of balancing work and study demands. Continuing education opportunities are important to Ontario primary health care nurse practitioners, and on-line continuing education offerings have been well received, but in order to be taken up by their target audience they must be relevant, readily accessible, flexible, affordable and offered over brief, intense periods of time using technology that is easy to use and Internet sites that are easily navigated.

Legal requirements for human-health based appeals of wind energy projects in ontario.

Science.gov (United States)

Engel, Albert M

2014-01-01

In 2009, the government of the province of Ontario, Canada passed new legislation to promote the development of renewable energy facilities, including wind energy facilities in the province. Throughout the legislative process, concerns were raised with respect to the effect of wind energy facilities on human health. Ultimately, the government established setbacks and sound level limits for wind energy facilities and provided Ontario residents with the right to appeal the approval of a wind energy facility on the ground that engaging in the facility in accordance with its approval will cause serious harm to human health. The first approval of a wind facility under the new legislation was issued in 2010 and since then, Ontario's Environmental Review Tribunal as well as Ontario's courts has been considering evidence proffered by appellants seeking revocation of approvals on the basis of serious harm to human health. To date, the evidence has been insufficient to support the revocation of a wind facility approval. This article reviews the legal basis for the dismissal of human-health based appeals.

Canadian federalism and the Canadian health care program: a comparison of Ontario and Quebec.

Science.gov (United States)

Palley, H A

1987-01-01

The Quebec and Ontario health insurance and health service delivery systems, developed within the parameters of federal regulations and national financial subsidies, provide generally universal and comprehensive basic hospital and medical benefits and increasingly provide for the delivery of long-term care services. Within a framework of cooperative federalism, the health care systems of Ontario and Quebec have developed uniquely. In terms of vital statistics, the health of Ontario and Quebec residents generally is comparable. In viewing expenditures, Quebec has a more clearly articulated plan for providing accessible services to low-income persons and for integrating health and social services, although it has faced some difficulties in seeking to achieve the latter goal. Its plans for decentralized services are counter-balanced by a strong provincial role in health policy decision-making. Quebec's political culture also allows the province to play a stronger role in hospital planning and in the regulation of physician income than one finds in Ontario. These political dynamics allow Quebec an advantage in control of costs. In Ontario, in spite of some recent setbacks, physician interests and hospital sector interests play a more active role in health system bargaining and are usually able to influence remuneration and resource allocation decisions more than physician interests and hospital sector interests in Quebec.

2010-01-01

The spatial and temporal variations of mercury (Hg) in sediments of the Pearl River Estuary (PRE) and the surrounding coastal area (South China Sea) were studied. In surface sediments, the concentrations of Hg ranged from 1.5 to 201 ng/g, with an average of 54.4 ng/g, displaying a decreasing trend with the distance from the estuary to the open sea. This pattern indicates that the anthropogenic emissions from the Pearl River Delta (PRD) region are probably the main sources of Hg in this coastal region. Using the 210 Pb dating technique, the historical changes in the concentrations and influxes of Hg in the last 100 years were also investigated. The variations in Hg influxes in sediment cores obviously correlate with the economic development and urbanization that has occurred the PRD region, especially in the last three decades. - The spatial and historical changes of Hg in sediment reflect the industrial development and urbanization of the region in south China.

Hobaugh, J.L.

1985-02-01

An aerial radiological survey was performed from 11 to 13 June 1983, over approximately a 64-square-kilometer (25-square-mile) area surrounding the Brookhaven National Laboratory (BNL). BNL is located in the center of Suffolk County, Long Island, New York. All gamma radiation data were collected by flying east-west lines spaced 76 meters (250 feet) apart at an altitude of 46 meters (150 feet) above ground level. Count rates obtained from the aerial platform were converted to exposure rates at 1 meter above the ground. The average background exposure rate in the survey area ranged from 5 to 10 microroentgens per hour (μR/h). The reported exposure rate values include an estimated cosmic ray contribution of 4.0 μR/h. Ground-based measurements made during the same time period were compared to the aerial survey results. Pressurized ion chamber readings and soil samples were taken from two locations within the aerial survey boundaries. Exposure rate values obtained from these measurement techniques were in agreement with those obtained from the aerial data. A total of 23 areas of man-made radioactivity were identified. The dominant isotopes found over these areas were cesium-137, sodium-22, manganese-54, and cobalt-60. A similar survey was conducted in May 1980. The 1983 survey results were similar to the 1980 results. Three areas of low level man-made activity were not reproduced by the 1983 data. Ten new areas were detected. The major difference occurred because of the increased sensitivity and spatial reduction brought on by lowering the altitude and decreasing the line spacing. 8 refs., 28 figs., 4 tabs

Public perceptions of energy issues in Ontario

International Nuclear Information System (INIS)

2004-11-01

In October 2004, the Environics Research Group conducted a telephone survey of 608 adult Ontarians to collect information on matters regarding energy; consumer confidence and protection; responsibilities of the Ontario Energy Board; and consumer information preferences. This report summarizes the key findings of the survey. According to the survey, the most important electricity and natural gas issue was identified as being price and cost issues, followed by reliability of supply, conservation, keeping utilities publicly owned, finding renewable sources of energy, and over-consumption. The survey revealed that Ontarians show much interest in conserving energy to save money, to protect the environment and ensure future energy supply, but they are generally sceptical that their interests are being protected on electricity and natural gas price issues. At least 9 in 10 Ontarians consider the tasks of the Ontario Energy Board to be important. The majority of Ontarians prefer to receive energy conservation information through the mail and from public regulators over a government department or a company. 10 tabs

Aerial radiological survey of the Feed Materials Production Center and surrounding area, Fernald, Ohio. Date of survey: April 1985

International Nuclear Information System (INIS)

1985-10-01

An aerial radiological survey was performed over the area surrounding the Feed Materials Production Center, located near Fernald, Ohio, during the period April 24 to 27, 1985. The survey covered a 70-square-kilometer (27-square-mile) area centered on the plant. The highest exposure rates, in excess of 0.35 milliroentgens per hour (mR/h), were inferred from the data measured directly over the plant. This radiation was due to the presence of nuclides which were consistent with normal plant operations. For the remainder of the survey area, the inferred radiation exposure rates, varying from 6 to 12 microroentgens per hour (μR/h), were due to naturally-occurring potassium, uranium, thorium, and daughter products. The reported exposure rate values include an estimated cosmic ray contribution of 3.7μR/h. Ground-based measurements, conducted during the time of the aerial survey, were compared to the aerial results. Pressurized ionization chamber readings and a group of soil samples were acquired at several locations within the survey area. The exposure rate values obtained from these measurements were in agreement with the inferred aerial results. Soil sample results showed several areas just outside the site boundary with slightly elevated amounts of U-238. The levels, however, were well below the detection limit of the aerial system. The only off-site area that showed apparent above background activity in the aerial data was directly west of the storage silos. The symmetric shape of the contours, however, suggests that these elevated levels are due to ''shine'' from material stored on-site in the silos and not to actual off-site contamination. Detailed comparison of the 1985 aerial survey data with a previous survey conducted in 1976 showed no significant change in any area outside the plant boundary. 6 refs., 9 figs., 3 tabs

1995-10-01

The purpose of the workshop was to review available geological and seismological data which could affect earthquake occurrence in southern Ontario and to develop a consensus on approaches that should be adopted for characterization of seismic hazard. The workshop was structured in technical sessions to focus presentations and discussions on four technical issues relevant to seismic hazard in southern Ontario, as follows: (1) The importance of geological and geophysical observations for the determination of seismic sources, (2) Methods and approaches which may be adopted for determining seismic sources based on integrated interpretations of geological and seismological information, (3) Methods and data which should be used for characterizing the seismicity parameters of seismic sources, and (4) Methods for assessment of vibratory ground motion hazard. The format of each session involved invited presentations of relevant data followed by open presentations by participants, a general discussion focusing on the relevance of the presented information for seismic hazard assessment in southern Ontario, then development of conclusions and recommendations. In the final session, the conclusions and recommendations were summarized and an open discussion was held to develop consensus. This report presents perspective summaries of the workshop technical sessions together with conclusions and recommendations prepared by the session chairs and the general chairman. 2 refs

An aerial radiological survey of the RMI facility and surrounding area, Ashtabula, Ohio: Date of survey, September 1985

1986-11-01

An aerial radiological survey was conducted over a 75-square-kilometer (30-square-mile) area surrounding the RMI facility in Ashtabula, Ohio, during the period between September 4 and 13, 1985. The survey was conducted at an altitude of 46 meters (150 ft). A second, more detailed survey was also performed over the RMI facility. This survey was conducted at an altitude of 30 meters (100 ft) and covered an area of about 2.6 square kilometers (1 sq mi) centered over the facility. Over most of the survey area, exposure rates varied from about 8 to 11 microentgens per hour (μR/h). Several areas of increased radioactivity were observed in addition to increased radioactivity over the RMI facility (exposure rates of up to 44 μR/h were detected). The increased radioactivity over the RMI facility was due to uranium; however, no evidence of uranium was found off site. A second site exhibiting increased radioactivity was located near a railroad siding. The anomalous radiation there was due primarily to elevated concentrations of radium. Ground samples from this location were found to contain 130,000 picocuries per gram (pCi/g) of radium-226. Two other regions of anomalous radiation were found on the shore of Lake Erie, near Pinney Dock. One of these sites contained elevated concentrations of potassium-40 (K-40). The spectrum from the second site indicated the source to be thorium. A fifth site was a facility located a few hundred meters east of the RMI plant. The spectrum from this site also indicated an increased amount of thorium. Finally, a sixth source was located in the eastern portion of the survey area. The spectrum from this site was found to be high in cesium-137 (Cs-137). 7 refs., 14 figs., 2 tabs

The Smoke-Free Ontario Act (SFOA) came into effect in May 2006 and included restrictions to outdoor hospitality areas by only permitting smoking on a patio if the area had no roof. (1) To assess the impact of the SFOA on the prevalence of smoke-free patios in Ontario and (2) to determine the proportion of venues where structural alterations were made rather than going smoke-free in order to achieve compliance with the SFOA. A telephone survey of 403 hospitality sector operators/owners in four clustered samples of Ontario, Canada. Based on completed surveys, the SFOA resulted in an increase in prevalence of smoke-free patios, from 5% (n=21) to 25% (n=99). Of the patios where smoking was permitted before the SFOA (n=382), 42% (n=161) had physical structures that would make smoking not permissible under the new act. Operators of half of these venues (n=80) made their patios smoke-free, with most indicating they had no choice given the costs or physical limitations to changing their outdoor environment. The other half (n=81) reported making physical changes, including removing roof structures to achieve compliance. The SFOA resulted in greater protection from outdoor secondhand smoke; however, most patios still permitted smoking. Half of the venues that complied with the SFOA by going smoke-free did so involuntarily because of structural and/or financial limitations. The majority of venue operators preferred to permit smoking on their patios, and only made their patios smoke-free when they were required to do so by law.

Important variables in explaining real-time peak price in the independent power market of Ontario

International Nuclear Information System (INIS)

Rueda, I.E.A.; Marathe, A.

2005-01-01

This paper uses support vector machines (SVM) based learning algorithm to select important variables that help explain the real-time peak electricity price in the Ontario market. The Ontario market was opened to competition only in May 2002. Due to the limited number of observations available, finding a set of variables that can explain the independent power market of Ontario (IMO) real-time peak price is a significant challenge for the traders and analysts. The kernel regressions of the explanatory variables on the IMO real-time average peak price show that non-linear dependencies exist between the explanatory variables and the IMO price. This non-linear relationship combined with the low variable-observation ratio rule out conventional statistical analysis. Hence, we use an alternative machine learning technique to find the important explanatory variables for the IMO real-time average peak price. SVM sensitivity analysis based results find that the IMO's predispatch average peak price, the actual import peak volume, the peak load of the Ontario market and the net available supply after accounting for load (energy excess) are some of the most important variables in explaining the real-time average peak price in the Ontario electricity market.

2002-01-01

Fifty one water samples were collected from production wells used for human consumption from Taiz City and its surroundings, Yemen Republic. The water quality was investigated with respect to bacteriological and physico-chemical parameters. The achieved results revealed that most water samples, especially from private wells, contain a high number of total coliforms (TC) which exceed the permissible limit recommended by the World Health Organization, WHO (1996). Also faecal coliforms (FC) were recorded in the majority of polluted samples. A quantitative estimation was done for each of temperature (18-26C), pH (6.12-8.79), total hardness (58-2200 mg/L), electrical conductivity (218-4600 m.Mohs), total dissolved solids (117-3700mg/L), nitrate (10-187mg/L) and type of aquifer (rocky and alluvium). It is worthy to notice that from the total of fifty-one wells, there was pollution in (65%) of them. Recommendations were suggested for the treatment of the water of such polluted wells and rigid government control in a trial to prevent human and animal illness. (author)

Recent investigations have suggested that small water bodies cover larger areas in northern peatlands than previously assumed. Their role in the carbon cycle and gas exchange rates are poorly constrained so far. To address this issue we measured CO2 and CH4 fluxes on a small water body (ca. 700 m2) and the surrounding floating mat in the Luther Marsh peatland in Ontario, Canada from July to September 2014. To this end we used closed chambers combined with a portable Los Gatos high-resolution trace gas analyzer at different water depths and distances from the shore on the pond and with different dominating plant types on the floating mat surrounding the pond. In addition, CO2 concentrations were recorded in high temporal resolution using an infrared sensor system during selected periods. Air and water temperature, humidity and temperature of the floating mat, wind speed and direction, photosynthetically active radiation, air pressure and relative humidity were also recorded as auxiliary data at the study site. The results show that pond and floating mat were sources of methane throughout the whole measuring period. Methane emissions via the ebullition pathway occurred predominantly near the shore and on the floating mat. During the daytime measurements the floating mat acted as a net sink and the pond as a net source of CO2. The dynamics of CO2 exchange was also strongly time dependent, as CO2 emissions from the pond strongly increased after mid-August. This suggests that photosynthesis was more affected by seasonal decline than respiration process in the pond and that the allochthonous component of the CO2 flux increased in relative importance towards fall.

The Status of Benthos in Lake Ontario

Walsh, M.L.; Agnew, D.A.; Donnelly, K.E.

1984-01-01

The response of the Ontario Hydro Thermoluminescence Dosimetry System to beta radiation in nuclear power station environments was evaluated. Synthetic beta spectra were constructed, based on activity samples from heat transport systems and fuelling machine contamination smears at nuclear power stations. Using these spectra and dosemeter energy response functions, an overall response factor for the skin dosemeter relative to skin dose at 7 mg.cm -2 was calculated. This calculation was done assuming three specific geometries: (1) an infinite uniformly contaminated plane source at a distance of 33 cm (50 mg.cm -2 total shielding) from the receptor; (2) an infinite cloud surrounding the receptor; (3) a point source at 33 cm. Based on these calculations, a conservative response factor of 0.7 has been chosen. This provides an equation for skin dose assignment, i.e. Skin Dose = 1.4 x Skin Dosemeter Reading when the skin dosemeter is directly calibrated in mGy(gamma). (author)

Creating a cultural analysis tool for the implementation of Ontario's civil mental health laws.

Science.gov (United States)

Dhand, Ruby

2016-01-01

Ethno-racial people with mental health disabilities experience multiple inequities and differential outcomes when interacting with Ontario's civil mental health laws. Given the increasing multi-racial population in Ontario, there is a need to develop mechanisms to address these intersecting issues. Other countries that have created evaluative tools for mental health legislation include the United Kingdom and Australia. Australia's Rights Analysis Tool, the United Kingdom's Race Equality Impact Assessment, the Scottish Recovery Tool, and the World Health Organization's Mental Health and Human Rights checklist are examples of evaluative tools developed for mental health legislation. Such a tool does not exist in Canada, let alone in Ontario specifically. Thus, this study developed a Cultural Analysis Tool (CAT) consisting of specific and meaningful thematic questions that can be used by practitioners when addressing issues of culture and equity for ethno-racial people with mental health disabilities interacting with Ontario's civil mental health laws. It is hoped that the CAT, and the research underlying its development, will enable practitioners to critically question whether cultural and intersecting concerns are being appropriately addressed within an ethno-racial client's case and, furthermore, how equitable outcomes can be achieved. This article describes and analyzes the methodology, research and qualitative data used to develop the CAT. It then presents and examines the CAT itself. The qualitative data was drawn from thirty-five semi-structured interviews with seven members of each of the following groups: (1) ethno-racial people with mental health disabilities including in-patients and ex-patients, (2) lawyers who practice in the area of mental health law, (3) health care professionals including psychiatrists, nurses and social workers, (4) service providers such as front-line case workers at mental health agencies and (5) adjudicators, government advisors

Ontario-U.S. power outages : impacts on critical infrastructure

International Nuclear Information System (INIS)

2006-01-01

This paper described the power outage and resulting blackout that occurred on August 14, 2003 and identified how critical infrastructure was directly and interdependently impacted in Canada. The aim of the paper was to assist critical infrastructure protection and emergency management professionals in assessing the potential impacts of large-scale critical infrastructure disruptions. Information for the study was acquired from Canadian and American media reports and cross-sectoral information sharing with provincial and federal governments and the private sector. The blackout impacted most of the sources and means of generating, transmitting and distributing power within the area, which in turn impacted all critical infrastructure sectors. Landline and cellular companies experienced operational difficulties, which meant that emergency responders were impacted. Newspapers and the electronic media struggled to release information to the public. The banking and finance industry experienced an immediate degradation of services. The power outage caused shipping and storage difficulties for commercial retailers and dairy producers. A number of incidents were reported where only partially treated waste water was released into neighbouring waterways. The timing of the blackout coincided with the closures of workplaces and created additional difficulties on transportation networks. Many gas station pumps were inoperable. Police, fire departments and ambulance services experienced a dramatic increase in the volume of calls received, and all branches of the emergency services sector encountered transportation delays and difficulties with communications equipment. Nuclear reactors were also impacted. An estimated 150,000 Government of Canada employees were unable to report to work. Estimates have indicated that the power outage cost Ontario's economy between $1 and $2 billion. The outage negatively impacted 82 per cent of small businesses in Ontario. 170 refs., 3 figs

Cried because I had no shoes : The impact of price caps on the Ontario electricity market

International Nuclear Information System (INIS)

Chan, A.

2002-01-01

In late 2002, the Ontario Premier announced a Nine-Point response to the competitive electricity regime in the province, which was followed by the release of draft legislation. This draft legislation called for a government imposed retail price cap of 4.3 cent kilo watt hour for the cost of energy, effective December 1, 2002 to 2006. In addition, the Premier indicated a retroactive refund would be forwarded to customers from May 1, 2002, for charges above the price cap. In this document, the author argued for a lessening of the price cap proposals, and supporting a market allowed to hold its course toward competitive markets in the future. The arguments put forth by the author were: (1) the imposition of price caps will hinder long-term economic viability in Ontario, (2) the benefits of competition cannot be interrupted by politically-motivated responses, (3) if the current path is followed Ontario may be headed towards blackouts, (4) deregulation is essential if Ontario is to remain competitive in the electricity marketplace, and (5) upcoming downgrade in Ontario's red index score. 3 tabs

In this work, the natural radiation background has been carried out for Palmyra city and its surroundings area. The study has covered gamma radiation measurements, indoor radon gas concentration and radionuclides levels in environmental samples (soil, water, plat). The results showed that indoor radon gas concentrations and radiation exposure rates are within the background levels. Also, the results showed that there is no artificial radiation in the area and there is no correlation between the natural radiation levels and the reported cancer cases. Therefore, the reported cancer cases in this area may be due to non-radiation cases, which must be investigated, or they are within the natural levels in Syria unless accurate statistics proves the opposite.

Full Text Available Richard Carew,1 Wojciech J Florkowski21Agriculture and Agri-Food Canada, Pacific Agri-Food Research Centre, Summerland, BC, Canada; 2Department of Agricultural and Applied Economics, University of Georgia, Griffin, GA, USAAbstract: The Ontario wine industry has undergone major transformative changes over the last two decades. These have corresponded to the implementation period of the Ontario Vintners Quality Alliance (VQA Act in 1999 and the launch of the Winery Strategic Plan, "Poised for Greatness," in 2002. While the Ontario wine regions have gained significant recognition in the production of premium quality wines, the industry is still dominated by a few large wine companies that produce the bulk of blended or "International Canadian Blends" (ICB, and multiple small/mid-sized firms that produce principally VQA wines. This paper analyzes how winery regulations, industry changes, institutions, and innovation have impacted the domestic production, consumption, and international trade, of premium quality wines. The results of the study highlight the regional economic impact of the wine industry in the Niagara region, the success of small/mid-sized boutique wineries producing premium quality wines for the domestic market, and the physical challenges required to improve domestic VQA wine retail distribution and bolster the international trade of wine exports. Domestic success has been attributed to the combination of natural endowments, entrepreneurial talent, established quality standards, and the adoption of improved viticulture practices.Keywords: Ontario, wine, quality standards

Surrounding land cover types as predictors of palustrine wetland vegetation quality in conterminous USA

Stapanian, Martin A.; Gara, Brian; Schumacher, William

2018-01-01

The loss of wetland habitats and their often-unique biological communities is a major environmental concern. We examined vegetation data obtained from 380 wetlands sampled in a statistical survey of wetlands in the USA. Our goal was to identify which surrounding land cover types best predict two indices of vegetation quality in wetlands at the regional scale. We considered palustrine wetlands in four regions (Coastal Plains, North Central East, Interior Plains, and West) in which the dominant vegetation was emergent, forested, or scrub-shrub. For each wetland, we calculated weighted proportions of eight land cover types surrounding the area in which vegetation was assessed, in four zones radiating from the edge of the assessment area to 2 km. Using Akaike's Information Criterion, we determined the best 1-, 2- and 3-predictor models of the two indices, using the weighted proportions of the land cover types as potential predictors. Mean values of the two indices were generally higher in the North Central East and Coastal Plains than the other regions for forested and emergent wetlands. In nearly all cases, the best predictors of the indices were not the dominant surrounding land cover types. Overall, proportions of forest (positive effect) and agriculture (negative effect) surrounding the assessment area were the best predictors of the two indices. One or both of these variables were included as predictors in 65 of the 72 models supported by the data. Wetlands surrounding the assessment area had a positive effect on the indices, and ranked third (33%) among the predictors included in supported models. Development had a negative effect on the indices and was included in only 28% of supported models. These results can be used to develop regional management plans for wetlands, such as creating forest buffers around wetlands, or to conserve zones between wetlands to increase habitat connectivity.

2006-01-01

The International Joint Commission has recently completed a five-year study (2000-2005) to review the operation of structures controlling the flows and levels of the Lake Ontario - St. Lawrence River system. In addition to addressing the multitude of stakeholder interests, the regulation plan review also considers environmental sustainability and integrity of wetlands and various ecosystem components. The present paper outlines the general approach, scientific methodology and applied management considerations of studies quantifying the relationships between hydrology and wetland plant assemblages (% occurrence, surface area) in Lake Ontario and the Upper and Lower St. Lawrence River. Although similar study designs were used across the study region, different methodologies were required that were specifically adapted to suit the important regional differences between the lake and river systems, range in water-level variations, and confounding factors (geomorphic types, exposure, sediment characteristics, downstream gradient of water quality, origin of water masses in the Lower River). Performance indicators (metrics), such as total area of wetland in meadow marsh vegetation type, that link wetland response to water levels will be used to assess the effects of different regulation plans under current and future (climate change) water-supply scenarios.

The distribution of physiotherapists in ontario: understanding the market drivers.

Holyoke, Paul; Verrier, Molly C; Landry, Michel D; Deber, Raisa B

2012-01-01

To understand the factors that affect the distribution of physiotherapists in Ontario by examining three potential influences in the multi-payer physiotherapy (PT) market: population need, critical mass (related to academic health science centres [AHSCs]), and market forces. Physiotherapist density and distribution were calculated from 2003 and 2005 College of Physiotherapists of Ontario registration data. Physiotherapists' workplaces were classified as not-for-profit (NFP) hospitals, other NFP, or for-profit (FP), and their locations were classified by census division (CD) types (cities and counties). Physiotherapist density varied significantly and distribution was neither uniformly responsive to population need, nor driven primarily by market forces. The largest factor was an AHSC in a CD; physiotherapists locate disproportionately in NFP hospitals in AHSCs rather than in the growing FP sector. While some patterns can be discerned in the distribution and densities of physiotherapists across Ontario, further work needs to be done to identify why population need and market forces appear to be less influential, and why CDs with AHSCs are so attractive to physiotherapists. With this additional information, it may be possible to identify ways to influence uneven distribution in the future.

A demand/supply and price outlook for electricity in Ontario

International Nuclear Information System (INIS)

Dalton, J.

2004-01-01

This paper examined electricity pricing issues for both the immediate future as well as over the long term. The near term outlook resources for the summer of 2004 were reviewed. Intermediate critical supply and demand issues were projected with consideration given to the return of the Pickering A plant and coal phase out. In the long term, it was considered that pricing and demand would reflect conservation issues and demand side response, as well as the timing of Requests For Proposals (RFPs) and the phase out of coal-fired capacity. The impact of the coal phase-out in Ontario was examined, with particular reference to timing and market structure implications. Potential conservation impacts were presented and projected Ontario supply/demand balances were evaluated. The challenges facing the new market structure include pricing dynamics and a reliance on RFPs. The significance of specifying diversity objectives was also discussed. It was concluded that the Ontario Ministry of Energy should play a role in establishing targets for conservation, renewable energy and the overall supply of electricity. Rigorous analysis is necessary before specifying targets in terms of hydroelectric and nuclear generation as opposed to non-fossil generation. tabs., figs

Ontario Hydro has produced on the order of 21 million Mg of coal fly ash over the past 40 years, of which, 80% has gone to various landfill sites in the province of Ontario. Hydrogeologic investigations have been performed in the vicinity of three Ontario Hydro coal ash landfill sites to assess the environmental impact of fly ash landfilling on the local groundwater regime. Two of the waste management facilities are associated with thermal generating stations (Lambton TGS and Nanticoke TGS) and are founded on relatively impermeable clay deposits. The third site, Birchwood Park, is a former sand and gravel pit for which the landfill design did not incorporate the use of a liner material. The rates of groundwater flow through the overburden materials a the three sites vary from less than 1 cm/a at the Lambton TGS site, to between 3.45 cm/a and 115 cm/a at contaminant transport at these sites also varies from being controlled by molecular diffusion to advection. This paper discusses the migration rates of contaminants from fly ash leachate at each of the three sites with implications to landfill containment and design

New avenues in cobalt-60 production at Ontario Hydro

International Nuclear Information System (INIS)

Mylvaganam, C.K.; Ronchka, R.A.

1990-01-01

Ontario Hydro produces cobalt-60 in the control rods of twelve power reactors. These reactors have a typical flux of 2 x 10 14 neutrons/cm 2 /s, making them efficient producers of cobalt-60. Current annual production is 45 million curies. Since the primary function of these reactors is the production of electricity, their flexibility to meet the needs of commercial cobalt production by the control rod route is limited. Ontario Hydro is therefore developing innovative production techniques, making use of the CANDU reactor's unique ability to be fuelled on-power. These techniques will enable production to better respond to the market's requirements for quantity and specific activity. As it is supplementary to control rod production, annual supply could potentially reach 165 million curies. (author)

Full Text Available We investigate some characteristics of foreshock activity of moderate and large earthquakes which occurred in the present century in Albania and the surrounding area. Using a prediction algorithm, based on possible foreshocks, we obtained a probabilistic relation between possible foreshocks and mainshocks. From documentary and instrumental data for the period 1901-1994 for the area between 39.0°- 43.0°N and 18.5°-21.5°E we evaluated the probability of the occurrence of mainshocks immediately after their possible foreshocks. The result shows that the probability that mainshocks with magnitude M ³ 6.0 are preceded by a foreshock with magnitude M ³ 4.4, distance £ about 50 km and time £ 10 days is 38% (6/16. The probability that one earthquake with M ³ 4.4 will be followed by a larger earthquake with M ³ 6.0 within about 50 km and 10 days is 1.3% (6/468, but the probability increases to 33% (1/3 if 7 earthquakes with M ³ 4.4 occur within about 50 km and 10 days. From instrumental data for the period 1971-1994, the probability that mainshocks with M ³ 5.0 are preceded by a foreshock with magnitude M ³ 4.0 is 33% (5/15. The probability that one earthquake with M ³ 4.0 will be followed by a larger earthquake with M ³ 5.0 within about 50 km and 10 days is 1.9% (5/262, but the probability increase to 5.6% (1/18 if 3 earthquakes with M ³ 4.0 occur within about 50 km and 10 days. We also found a regional variation of foreshock activity with activity decreasing from the Vlora-Elbasani-Dibra transversal seismic belt to the Ionian-Adriatic seismic zone to the interior part of Albania seismic zone.

Magnetic map of the Irish Hills and surrounding areas, San Luis Obispo County, central California

A magnetic map of the Irish Hills and surrounding areas was created as part of a cooperative research and development agreement with the Pacific Gas and Electric Company and is intended to promote further understanding of the areal geology and structure by serving as a basis for geophysical interpretations and by supporting geological mapping, mineral and water resource investigations, and other topical studies. Local spatial variations in the Earth's magnetic field (evident as anomalies on magnetic maps) reflect the distribution of magnetic minerals, primarily magnetite, in the underlying rocks. In many cases the volume content of magnetic minerals can be related to rock type, and abrupt spatial changes in the amount of magnetic minerals can be related to either lithologic or structural boundaries. Magnetic susceptibility measurements from the area indicate that bodies of serpentinite and other mafic and ultramafic rocks tend to produce the most intense magnetic anomalies, but such generalizations must be applied with caution because some sedimentary units also can produce measurable magnetic anomalies. Remanent magnetization does not appear to be a significant source for magnetic anomalies because it is an order of magnitude less than the induced magnetization. The map is a mosaic of three separate surveys collected by (1) fixed-wing aircraft at a nominal height of 305 m, (2) by boat with the sensor at sea level, and (3) by helicopter. The helicopter survey was flown by New-Sense Geophysics in October 2009 along flight lines spaced 150-m apart and at a nominal terrain clearance of 50 to 100 m. Tie lines were flown 1,500-m apart. Data were adjusted for lag error and diurnal field variations. Further processing included microleveling using the tie lines and subtraction of the reference field defined by International Geomagnetic Reference Field (IGRF) 2005 extrapolated to August 1, 2008.

Health impact assessment of Ontario's green energy and green economy act. The roles of environmental informatics in sustainability

Rattle, Robert

2013-01-01

Renewable energy received a boost in Ontario, Canada with the Green Energy and Green Economy Act (GEGEA), ushering in a new Feed-in-Tariff (FIT) program modelled on programs from Germany, Spain, Denmark and other jurisdictions. Information about lessons learned elsewhere has clearly benefited the Ontario experience. Part of the Ontario program included streamlining the impact assessment process to facilitate the swift development of provincial renewable energy capacities. In this context, the GEGEA has been remarkably successful, generating renewable energy sector capacities, resources, projects and their spin-off benefits in Ontario, along with more sustainable electricity system. Environmentalists along with industry continue to laud the benefits of renewable energy and the GEGEA, and with good reason. Renewable energy generation in Ontario has grown from to 2 per cent in 2012 and is expected to reach 10 per cent in 2013. (orig.)

After the Fukushima nuclear accident the BMU asked the SSK to check the guidelines for radiation emergency preparedness. Based on the information gained by the Japanese experience the SSK recommended to plan nuclear emergencies irrespective of the calculated probability of occurrence, but according to the effects of an INES 7 event. The SSK has recommended new planning areas for the surroundings of nuclear power plants based on a method developed by the SSK. This approach requires enlarged planning areas.

Demands for improvement in working surroundings for older workers in nuclear power plants

Shizawa, Yasuhiro; Sakuda, Hiroshi; Ohashi, Tomoki

2003-01-01

Workers in three nuclear power plants belonging to Kansai Electric Power Co., Inc. were asked to complete a questionnaire. According to the accident reports, workers aged 50 or older had more accidents than those in 30s or 40s. Moreover, it is predicted that the average age of workers in Japan will increase during the first half of the 21st century. Therefore, investigations into working surroundings in which older workers can better perform their work would be useful. To this end, a questionnaire addressing issues related to working surroundings was conducted among workers in nuclear power plants and the demands for improvement of working surroundings for older workers are summarized. The demands of 'better lighting', 'making things less heavy', and installation of an elevator' were correlated with age, indicating that younger people have a tendency not to notice these issues. Thus, if the authority deciding on improvements in working surroundings is not an older worker, it is especially important that lighting, the weights of objects to be moved, and methods of moving between floors is taken into account. Findings specific to nuclear power plants were also reported. For example, employees who worked in the non-radiation controlled area demanded the installation of air conditioning and those who worked in the radiation controlled area demanded the establishment of a rest area. Further, we have developed a guidebook entitled 'a guidebook supporting workers' cooperation among all generations' to promote cooperation between older and younger workers. (author)

Impact of Ontario electricity industry structure on the viability of cogeneration projects

International Nuclear Information System (INIS)

Chuddy, B.

1999-01-01

A review of Ontario Hydro's existing market structure and how its move toward a more competitive profile can be advantageous for cogeneration projects was presented. Ontario's existing electric power supply is as follows: 6 fossil fuels stations generate a total of 9, 969 MW of electricity, 23 NUG stations generate 1,541 MW, 3 nuclear stations generate a total of 9,028 MW and 69 hydro-electric stations generates 6,751 MW of electricity. The criteria and characteristics for cogeneration projects were listed. The paper also discussed other topics such as the market price of power, outstanding regulatory issues, market volatility and relative pricing. The prognosis for Ontario cogeneration projects for the early years from 1999-2004 is that for economic reasons, only big projects with large loads of 200 to 800 MW will be considered. In later years, other projects will become economic

Toxicity regulation of radioactive liquid waste effluent from CANDU stations - lessons from Ontario's MISA program

Rodgers, D.W.

2009-01-01

Toxicity testing became an issue for Ontario's CANDU stations, when it was required under Ontario's MISA regulations for the Electricity Generation Sector. In initial tests, radioactive liquid waste (RLW) effluent was intermittently toxic to both rainbow trout and Daphnia. Significant differences in RLW toxicity were apparent among stations and contributing streams. Specific treatment systems were designed for three stations, with the fourth electing to use existing treatment systems. Stations now use a combination of chemical analysis and treatment to regulate RLW toxicity. Studies of Ontario CANDU stations provide a basis for minimizing costs and environmental effects of new nuclear stations. (author)

In the last decade, there have been a number of action plans published to highlight the importance of preventing osteoporosis and related fractures. In the province of Ontario Canada, the Ministry of Health provided funding for the Ontario Osteoporosis Strategy. The goal is to reduce morbidity, mortality, and costs from osteoporosis and related fractures through an integrated and comprehensive approach aimed at health promotion and disease management. This paper describes the components of the Ontario Osteoporosis Strategy and progress on implementation efforts as of March 2009. There are five main components: health promotion; bone mineral density testing, access, and quality; postfracture care; professional education; and research and evaluation. Responsibility for implementation of the initiatives within the components is shared across a number of professional and patient organizations and academic teaching hospitals with osteoporosis researchers. The lessons learned from each phase of the development, implementation, and evaluation of the Ontario Osteoporosis Strategy provides a tremendous opportunity to inform other jurisdictions embarking on implementing similar large-scale bone health initiatives.

This study was undertaken to evaluate the microbial quality of the soft drinks served by fast food restaurants and gas station convenience stores in Griffin, GA, and surrounding areas. The soft drinks were collected from the dispensing machines in 8 fast food restaurants or gas station convenience stores in 2005 (n = 25) and in 10 fast food restaurants or gas station convenience stores in 2006 (n = 43) and 2007 (n = 43). One hundred milliliters of each soft drink was filtered through a hydrophobic grid membrane filter. The remaining portion of the soft drink was kept at room temperature for 4 h before sampling in order to mimic the possible holding time between purchase and consumption. The membrane filters were sampled for total aerobic bacteria, Enterobacteriaceae, lactic acid bacteria, and yeasts and molds. The microbial counts in the 2006 samples were numerically higher than the counts in the 2007 samples except for the average lactic acid bacteria counts, and were either significantly or numerically higher than the counts in the 2005 samples. Soft drinks sampled after the 4-h holding period had relatively higher counts than those sampled initially, with a few exceptions. Some soft drinks had over 4 log CFU/100 ml of total aerobic bacteria, Enterobacteriaceae, lactic acid bacteria, and yeast and mold cells. The study revealed the microbial quality of soft drinks served by dispensing machines in Griffin, GA, and surrounding areas, emphasizing the importance of effective sanitizing practice in retail settings.

1981-02-01

Rattray Marsh, an 8 ha marsh on the Lake Ontario shoreline at Mississauga, Ontario, is an important local habitat for waterfowl and shorebirds during spring and fall migration. A study was conducted to determine the distribution of nutrients (carbon, nitrogen, and phosphorus) and potential trace metal and organochlorine pollutants in the marsh as evidenced by the sedimentary concentrations of these compounds. Generally, copper, zinc, lead, and mercury were higher in concentration in local soils than in Lake Ontario sediments. Metals and organic carbon levels did not correlate, and the metals appeared to be associated with silts and clays. Organochlorine contaminants include p,p1-DDE, p,p1-DDD, p,p1-DDT, alpha-chlordane, PCB, mirex, and HCB.

The Independent Electricity Market Operator (IMO) has monitored the state of electricity demand and available supply in Ontario and has reported its findings to the Minister of Energy, Science and Technology and to the Ontario Energy Board. This report presents the IMO's assessment of the adequacy of resources and transmission for the Ontario electricity system for the 18-month period from January 2002 to June 2003. The assessment was based on current information on forecasts of electricity demand and available supply. The existing installed generation within Ontario was summarized. Existing power facilities include nuclear, coal, oil, gas, hydroelectric, wind-powered, wood and waste-fuelled generation. The installations range from less than 1 MW in size to 881 MW net electrical output. The total generating capacity in Ontario is 29,523 MW, excluding embedded generators that are not managed by the Ontario Electricity Financial Corporation or generation not connected to the IMO-controlled grid. In addition, the Bruce Nuclear Unit was not included because it is currently in laid-up state. This report discussed changes from the previous 18-month outlook in terms of power demand. It also presented outlooks of the transmission outage plan, system voltage, thermal concerns and forced outages. The general conclusion reached in this report is that there will be sufficient resources and transmission available to Ontario to supply Ontario demands and to meet the Northeast Power Coordinating Council (NPCC) resource criteria for the next 18 months. tabs., figs

The result of economical study about demand of electric and water supply in Madura Island in 2015 will increase double for domestic or support industry in Madura Island which have to be solved sooner. One way which is considered to solve the problem is Desalination with nuclear electrical plant. In order to support the installation of nuclear Desalination plant, it is needed site free or far from active fault. Active fault is mainly factor to reject the area on site selection process. Aim of the research is to get geological information and identify of active fault in the site candidate of nuclear Desalination plant at Ketapang area and its surrounding by interpretation of air photos and Landsat imagery, geological and structure geological mapping as well as trenching. The lithology of Ketapang and Sokobana site candidate consists of reef and chalky limestone with form of morphology is undulating hills. Structurally, research areas forms a mono cline with east-westerly trending axis, plunging 10 o to E, the direction of strike is W-E, dip 10 o -30 o to the north. This research concludes that an active fault was not found in the area. (author)

Notes for remarks by William A. Farlinger, chairman of Ontario Hydro

Farlinger, W.A.

1997-01-01

The advantages of convergence for gas and electric companies were discussed. Both utilities possess transmission lines, rights of way, billing systems and long-term customer relationships. The speaker, Chairman of Ontario Hydro, suggested that within a few years, customers may be in a position to choose their power supplier. Ontario Hydro's vision for convergence and the recent restructuring of the Corporation into three new signature companies (generation, transmission, retail) were described. In this process Ontario Hydro has taken steps toward open access to the grid by all producers, competition among many sellers and buyers, and choice of supplier by consumers for lower cost power. One of the basic driving forces for convergence in the energy field is the interchangeability of electricity or gas. Some municipalities have already implemented joint gas and electricity meter reading, and there are many other ways in which converge can provide cheaper power and better service to the consumer. Ultimately, convergence would mean that monopolies would disappear, as would the boundaries between the gas and electricity industries

Rees, C.; Bradley, D.; DeYoe, D.

2007-03-01

This summary provided details of a pre-feasibility workbook designed to assist communities and developers in better understanding bioenergy challenges and opportunities in Ontario. The workbook examined issues related to the conversion of biomass through thermal conversion technologies and focused on combined heat and power projects that used forest and agricultural biomass in order to produce up to 10 MW of electricity under the Ontario Renewable Standard Offer Program. As part of the program, new generators of no more than 10 MW are paid a base rate of 11 cents per kWh and an additional 3.52 cents per kWh for on-peak production. The workbook was comprised of a review of biomass supply in the eastern Ontario region and included both forested and abandoned farm lands. A base-line financial analysis was included to assess the feasibility of projects using combustion, pyrolysis, and gasification technologies. Biomass sources in the region included mill residue, harvest waste, biomass mortality from natural events, stand management, and standing timber. Key elements required for parties interested in considering a bioenergy business initiative were also included

AMO's [Association of Municipalities of Ontario] policy on refillable beverage containers

Energy Technology Data Exchange (ETDEWEB)

1992-04-01

The policy of the Association of Municipalities of Ontario (AMO) regarding refillable beverage containers is explained, and a response is made to the Ontario Soft Drink Association (OSDA's) top-up offer to municipalities. A background and overview is presented of current and historical policy on beverage containers, including measures enacted by other provinces and countries. AMO strongly urges the provincial government to increase the presence of refillable containers, first because reuse is preferrable to recycling, and second because Ontario's current recycling systems are not self-sufficient or sustainable in their present form. Refillable plastic bottles offer an opportunity for change in waste management similar to the Blue Box recycling initiative. It is recommended that the entire beverage industry voluntarily, or legislated by the provincial government, provide refillable containers as a consumer option and institute a deposit system to collect these containers. This system will promote full-cost accounting. OSDA's offer to top up Blue Box operating costs is rejected with the caveat of short-term financial agreements. The refillable concept should also be expanded to other packaged products. 2 tabs.

Clarkson, J.

2006-01-01

Manitoba currently generates 5500 MW of electricity, and has the potential to add another 5000 MW of clean energy. Nearly 2000 MW of Manitoba's electricity is currently being sold to the United States. New transmission sites will ensure both grid reliability and energy security for Ontario, and power exchanges are expected to reduce costs. This presentation provided details of a memorandum of understanding (MOU) between Ontario and Manitoba concerning energy sales across existing and future transmission infrastructure. Peak energy sales were expected to reach 1000 MW in the near future. Options for the interconnection included direct high voltage direct current (HVDC) lines to Sudbury as well as lines through Thunder Bay and Winnipeg. Manitoba's existing hydro sites were outlined, and potential sites were reviewed. In addition to presenting new supply options, this presentation described generation and transmission approval processes, as well as construction schedules for new sites and interconnection points. It was concluded that while there is currently a provincial focus on electricity supply and demand, new generation technologies will make interprovincial electricity agreements economically viable. tabs., figs

Insight conference reports : Ontario power summit : embrace the changes, face the challenges

2002-01-01

The main focus of this conference was on the current changes within Ontario's electricity industry and what can be learned from the experience of other jurisdictions. Opinions regarding the switch to open competition in Ontario on May 1, 2002 have been extremely varied. It was noted that open competition generally brings down electricity prices and is beneficial in introducing innovations. Opponents of competition are quick to point out that both California and Alberta have experienced the opposite with open markets. The presentations described the factors that contributed to the creation of an open electricity market in Ontario with reference to the unsustainable electricity rates of the 1990s. Participants at the conference also expressed their views regarding future electricity prices, and presented suggestions of how power transmission, distribution and generation can be optimized while protecting the consumer. A total of 18 papers were presented at the conference, of which 4 were indexed separately for inclusion in the database. refs., tabs., figs

Ontario's 2013 Long Term Energy /Plan (LTEP) takes a pragmatic approach. The plan is designed to balance the following five principles namely: Cost effectiveness, Reliability, Clean energy, Community engagement, and Emphasis on conservation and demand management before building new generation. By taking a pragmatic and flexible approach and balancing these principles, Ontario's 2013 Long Term Energy Plan builds on the foundation laid by the 2010 LTEP while also lowering the projected total system costs. The key elements of the 2013 LTEP are described in this paper by highlighting the major features of these elements. (author)

Comparison of Ontario Hydro's performance with world power reactors - 1981

International Nuclear Information System (INIS)

Dumka, B.R.

1982-04-01

The performance of Ontario Hydro's CANDU reactors in 1981 is compared with that of 123 world nuclear power reactors rated at 500 MW(e) or greater. The report is based on data extracted from publications, as well as correspondence with a number of utilities. The basis used is the gross capacity factor, which is defined as gross unit generation divided by the perfect gross output for the period of interest. The lowest of the published turbine and generator design ratings is used to determine the perfect gross output, unless the unit has been proven capable of consistently exceeding this value. The first six reactors in the rankings were CANDU reactors operated by Ontario Hydro

Full Text Available Artificial explosions are commonly used to prevent rockburst in deep roadways. However, the dissipation of the impact stress wave within the artificial blasting damage zone (ABDZ of the rocks surrounding a deep roadway has not yet been clarified. The surrounding rocks were divided into the elastic zone, blasting damage zone, plastic zone, and anchorage zone in this research. Meanwhile, the ABDZ was divided into the pulverizing area, fractured area, and cracked area from the inside out. Besides, the model of the normal incidence of the impact stress waves in the ABDZ was established; the attenuation coefficient of the amplitude of the impact stress waves was obtained after it passed through the intact rock mass, and ABDZ, to the anchorage zone. In addition, a numerical simulation was used to study the dynamic response of the vertical stress and impact-induced vibration energy in the surrounding rocks. By doing so, the dissipation of the impact stress waves within the ABDZ of the surrounding rocks was revealed. As demonstrated in the field application, the establishment of the ABDZ in the surrounding rocks reduced the effect of the impact-induced vibration energy on the anchorage support system of the roadway.

Implementing Indigenous Education Policy Directives in Ontario Public Schools: Experiences, Challenges and Successful Practices

Directory of Open Access Journals (Sweden)

Emily Milne

2017-08-01

Full Text Available The Ontario Ministry of Education has declared a commitment to Indigenous student success and has advanced a policy framework that articulates inclusion of Indigenous content in schooling curriculum (Ontario Ministry of Education, 2007. What are the perceptions among educators and parents regarding the implementation of policy directives, and what is seen to encourage or limit meaningful implementation? To answer these questions, this article draws on interviews with 100 Indigenous (mainly Haudenosaunee, Anishinaabe, and Métis and non-Indigenous parents and educators from Ontario Canada. Policy directives are seen to benefit Indigenous and non-Indigenous students. Interviews also reveal challenges to implementing Indigenous curricular policy, such as unawareness and intimidation among non-Indigenous educators regarding how to teach material. Policy implications are considered.

Purpose: To investigate the prevalence of total quality culture (TQC) within radiation therapy (RT) departments across Ontario, Canada. Methods: A prospective quantitative survey was distributed within RT departments across Ontario, Canada using the Miller Consulting Group Quality Culture survey. Findings: Ninety percent of managers (9/10) and 50% of employees (261/519) participated. There was concordance between managers and staff that overall RT departments exhibit a work culture that somewhat resembles TQC. Both groups scored 55% of the categories as somewhat agree with TQC and 9% of categories as no TQC. There was discordance in views for 36% of the categories, where managers scored a higher prevalence of TQC compared to their therapists. Larger RT departments (>50 employees) had more prevalence of discrepancy between group scores. Conclusions: This is the first study to report on the prevalence of TQC within RT departments. Strategies designed for on-going continuous improvement will benefit staff, RT managers, continuity of patient care and patient safety within RT departments.

Ontario's Poverty Reduction Strategy: A Critical Discourse Analysis.

Benbow, Sarah; Gorlick, Carolyne; Forchuk, Cheryl; Ward-Griffin, Catherine; Berman, Helene

2016-01-01

This article overviews the second phase of a two-phase study which examined experiences of health and social exclusion among mothers experiencing homelessness in Ontario, Canada. A critical discourse analysis was employed to analyze the policy document, Realizing Our Potential: Ontario's Poverty Reduction Strategy, 2014-2019. In nursing, analysis of policy is an emerging form of scholarship, one that draws attention to the macro levels influencing health and health promotion, such as the social determinants of health, and the policies that impact them. The clear neo-liberal underpinnings, within the strategy, with a focus on productivity and labor market participation leave little room for an understanding of poverty reduction from a human rights perspective. Further, gender-neutrality rendered the poverty experienced by women, and mothers, invisible. Notably, there were a lack of deadlines, target dates, and thorough action and evaluation plans. Such absence troubles whether poverty reduction is truly a priority for the government, and society as a whole.

Protected areas and their surrounding territory: socioecological systems in the context of ecological solidarity.

Mathevet, Raphaël; Thompson, John D; Folke, Carl

2016-01-01

The concept of ecological solidarity (ES) is a major feature of the 2006 law reforming national park policy in France. In the context of biodiversity conservation, the objectives of this study are to outline the historical development of ES, provide a working definition, and present a method for its implementation that combines environmental pragmatism and adaptive management. First, we highlight how ES provides a focus on the interdependencies among humans and nonhuman components of the socioecological system. In doing so, we identify ES within a framework that distinguishes ecological, socioecological, and sociopolitical interdependencies. In making such interdependencies apparent to humans who are not aware of their existence, the concept of ES promotes collective action as an alternative or complementary approach to state- or market-based approaches. By focusing on the awareness, feelings, and acknowledgement of interdependencies between actors and between humans and nonhumans, we present and discuss a learning-based approach (participatory modeling) that allows stakeholders to work together to construct cultural landscapes for present and future generations. Using two case studies, we show how an ES analysis goes beyond the ecosystem management approach to take into account how human interactions with the environment embody cultural, social, and economic values and endorse an ethically integrated science of care and responsibility. ES recognizes the diversity of these values as a practical foundation for socially engaged and accountable actions. Finally, we discuss how ES enhances academic support for a socioecological systems approach to biodiversity conservation and promotes collaboration with decision-makers and stakeholders involved in the adaptive management of protected areas and their surrounding landscapes.

The Ontario Energy Board`s draft standard supply service code: effects on air quality

Energy Technology Data Exchange (ETDEWEB)

Gibbons, J.; Bjorkquist, S. [Ontario Clean Air Alliance, Toronto, ON (Canada)

1999-06-29

The Ontario Clean Air Alliance (OCAA), a coalition of 67 organizations, takes issue with the Ontario Energy Board`s draft document `Standard Supply Service Code`, particularly sections 2.2.2. and 2.5.2 which they claim are not in the public interest unless the Ontario government implements the OCAA`s recommended emission caps. The alliance is of the view that without strict new environmental regulations the proposed Code would encourage the use of coal for electricity generation. Public health, the environment, consumer interests, job creation and promotion of a competitive electricity market would all be jeopardized by this development, the alliance states. The argument is supported by extensive reference to the Final Report of the Ontario Market Design Committee (MDC) which also emphasized the importance of combining the introduction of competition with appropriate environmental regulations, singling out the emission cap and trade program, and recommending that it be launched concurrently with the electricity market opening for competition. The view of the MDC was that public support for restructuring would not be forthcoming in the absence of regulatory measures to control power plant emissions. 25 refs.

Emissions trading in the real world : Ontario Power Generation's domestic and international trading activities

International Nuclear Information System (INIS)

Jantzi, B.

2001-01-01

In this presentation, the author discussed Ontario Power Generation's voluntary commitment to stabilize carbon dioxide equivalent emissions at 1990 levels. To do so, Ontario Power Generation is implementing a series of green energy initiatives, a corporate tree planting program, internal energy efficiency, and an emission reduction trading (ERT). The emphasis was placed on emission trading, where Ontario Power Generation is a leader in the field of greenhouse gas, nitrogen oxide and sulphur dioxide trading in Canada. The approach to trading adopted was explained, with the specifics provided for each of the different categories of emissions. Some examples further illustrated the process. The outlook for the future was outlined, with plans for the geological sequestration of carbon dioxide and enhanced oil recovery, low nitrogen oxide gasoline additive. The benefits of emission trading were discussed from the perspective of Ontario Power Generation and the environment, such as allowing real reductions in emissions in a cost effective manner, enhanced risk management, investments in emissions reductions. The author argued that emission reduction is the way of the future, representing the only way in which the greenhouse gas emissions reductions required to minimize global climate change will be accomplished

2017-01-01

The objective of this study was to evaluate the changes in demographic, geographic, and practice characteristics of all Ontario psychiatrists between 2003 and 2013 and their implication for access to psychiatrists. We included all psychiatrists who were clinically active in Ontario in any year from 2003 to 2013. For each psychiatrist, we reported age, sex, years since medical school graduation, geographic practice region, and practice characteristics such as total number of inpatients, outpatients, and outpatient visit frequencies. In 2013, there were 2070 psychiatrists, with nearly half (47%) more than 30 years since medical school graduation. Female psychiatrists comprised 41% of all psychiatrists in 2013 but 56% of all psychiatrists within 15 years of medical school graduation. Between 2003 and 2013, there was a 17% increase in the total number of psychiatrists, with the largest growth in psychiatrists occurring in the group more than 30 years from medical school graduation. Over these 11 years, the mean (SD) number of unique outpatients seen by a psychiatrist annually increased from 208 (228) to 249 (275) (19.5%; P = 0.001), with male psychiatrists, on average, seeing more outpatients annually than female psychiatrists. The number of outpatients seen by psychiatrists is slowly increasing. However, the large proportion of aging psychiatrists, the high concentration of psychiatrists in urban settings, and the increase in the number of female psychiatrists with smaller practices suggest that without radical changes to the way psychiatrists practice, access to psychiatrists will remain a challenge in Ontario.

To investigate whether the vessels surrounding a nodule depicted on non-contrast, low-dose computed tomography (LDCT) can discriminate benign and malignant screen detected nodules. We collected a dataset consisting of LDCT scans acquired on 100 subjects from the Pittsburgh Lung Screening study (PLuSS). Fifty subjects were diagnosed with lung cancer and 50 subjects had suspicious nodules later proven benign. For the lung cancer cases, the location of the malignant nodule in the LDCT scans was known; while for the benign cases, the largest nodule in the LDCT scan was used in the analysis. A computer algorithm was developed to identify surrounding vessels and quantify the number and volume of vessels that were connected or near the nodule. A nonparametric receiver operating characteristic (ROC) analysis was performed based on a single nodule per subject to assess the discriminability of the surrounding vessels to provide a lung cancer diagnosis. Odds ratio (OR) were computed to determine the probability of a nodule being lung cancer based on the vessel features. The areas under the ROC curves (AUCs) for vessel count and vessel volume were 0.722 (95% CI=0.616-0.811, plung cancer group 9.7 (±9.6) compared to the non-lung cancer group 4.0 (±4.3) CONCLUSION: Our preliminary results showed that malignant nodules are often surrounded by more vessels compared to benign nodules, suggesting that the surrounding vessel characteristics could serve as lung cancer biomarker for indeterminate nodules detected during LDCT lung cancer screening using only the information collected during the initial visit.

The safety of Ontario's nuclear power reactor. A scientific and technical review. Report to the Minister

International Nuclear Information System (INIS)

Hare, F.K.

1988-01-01

In December 1986 a study of the safety of the design, operating procedures and emergency plans associated with Ontario Hydro's nuclear generating plants was commissioned by the government of the province of Ontario. After receiving briefs from many interested groups and individuals, visiting the power plants, and consulting with nuclear industry and regulatory representatives in Canada and other countries, the commissioner presented this report to the Minister of Energy for Ontario. His major conclusion is that Ontario Hydro reactors are being operated safely and at high standards of technical performance. No significant adverse impact has been detected in either the work force or the public. The risk of accidents serious enough to affect the public adversely can never be zero, but is very remote. Major recommendations are that: Ontario Hydro re-examine its operational organization closely and commission a study of factors affecting human performance; and, that priority be given to finding a solution to pressure tube performance problems and to improving in-reactor monitoring. Sixteen other recommendations are presented relating to research and development, information exchange with other organizations, reactor performance, training, severe accident analysis, the provincial nuclear emergency plan, epidemiological studies, the Atomic Energy Control Board, public hearings, and women in the nuclear industry

Consistent and robust determination of border ownership based on asymmetric surrounding contrast.

Determination of the figure region in an image is a fundamental step toward surface construction, shape coding, and object representation. Localized, asymmetric surround modulation, reported neurophysiologically in early-to-intermediate-level visual areas, has been proposed as a mechanism for figure-ground segregation. We investigated, computationally, whether such surround modulation is capable of yielding consistent and robust determination of figure side for various stimuli. Our surround modulation model showed a surprisingly high consistency among pseudorandom block stimuli, with greater consistency for stimuli that yielded higher accuracy of, and shorter reaction times in, human perception. Our analyses revealed that the localized, asymmetric organization of surrounds is crucial in the detection of the contrast imbalance that leads to the determination of the direction of figure with respect to the border. The model also exhibited robustness for gray-scaled natural images, with a mean correct rate of 67%, which was similar to that of figure-side determination in human perception through a small window and of machine-vision algorithms based on local processing. These results suggest a crucial role of surround modulation in the local processing of figure-ground segregation. Copyright © 2012 Elsevier Ltd. All rights reserved.

Power for the future : towards a sustainable electricity system for Ontario

Ontario's electricity system has undergone major changes since 1998, when the Hydro-Electric Power Commission was divided into four separate entities, Ontario Power Generation, Hydro One, the Ontario Electricity Financial Corporation, and the Electrical Safety Authority. In addition, retail and wholesale electricity markets were introduced in 2002 under the supervision of the Ontario Energy Board. The removal from service of several nuclear generating facilities in the province led to greater reliance on coal-fired generation to meet energy demands. In 2003, the newly elected provincial government made a commitment to phase out coal-fired plants by 2007 for environmental reasons. It is estimated that all the the existing nuclear facilities will reach their projected operational lifetimes by 2018. Given the province's growing electricity demand, several options have been proposed as to how future energy needs could be met. The options range from investment into low-impact renewable energy sources such as small-scale hydro, solar, biomass and wind, to the construction of new nuclear generating facilities. The Pembina Institute and the Canadian Environmental Law Association examined the following four key issues regarding Ontario's future direction in electricity generation, transmission and distribution: (1) by how much can electricity demand be reduced through the adoption of energy efficient technologies, fuel switching, cogeneration and demand response measures, (2) how much electricity supply can be obtained from low-impact renewable energy sources, (3) how should the grid demand be met once the electricity system has maximized the technically and economically feasible contributions from energy efficiency, fuel switching, cogeneration, response management measures (RMM) and renewable energy sources, and (4) what public policies should the province adopt to maximize energy efficiency, fuel switching, cogeneration, RMM and renewable energy sources.

New Ontario power legislation aims to protect consumers

Energy Technology Data Exchange (ETDEWEB)

Anon.

2000-09-01

New legislation designed to improve regulation of the electricity sector in Ontario was introduced by the provincial government in June 2000, the first such legislation since the government mandated an open electricity market with the Energy Competition Act of 1998. The new legislation is described as narrowly focused on putting limits on local power rate increases. The legislation was introduced in combination with a directive to the Ontario Energy Board, and is designed to ensure that the Board approves municipal electric utility rates only when certain conditions are met. The Energy Minister was at great pains to point out that the legislation should not be interpreted as the government interfering in the marketplace, it is merely to help the utility wires side of the business during a two-year transition period. Municipal authorities reacted unfavorably to the legislation because it appears to require them to return significant assets to their utilities, assets that they considered as theirs under municipal restructuring. Energy Probe, an environmental advocacy group, suggested an alternative to the legislation, i. e., the government should allow the price increases requested by the municipal utilities to go through, but to leave consumers whole, it should impose a windfall profits tax on municipal governments, use the proceeds to reduce debt retirement taxes in the electricity bill, a leftover from Ontario Hydro's debt and stranded nuclear waste liabilities, and eliminate the province's own electricity tax on consumers. No direct reaction has been received from the Minister to date. If the legislation is passed in its present form it will prevent municipalities from using windfall profits from their utilities to justify rate hikes.

1999-01-01

The Independent Power Producers Society of Ontario and the Canadian Energy Efficiency Alliance (IPPSO/CEEA) support the government's initiatives in a white paper to aid in ensuring improved environmental performance by Ontario's new competitive electricity sector. IPPSO/CEEA is pleased that the White Paper recognizes the need to ensure that the new environmental initiatives rely as much as possible on market-based mechanisms and the use of more efficient and environmentally friendly technology, as well as the fact that they facilitate access for generators. Given that the timetable is short for setting forth the new and necessary environmental regulations prior to the market opening, IPPSO/CEEA developed consolidated positions on some of the important considerations and elements for the new Ontario regulations. IPPSO/CEEA fully support regulations for the new market that will reduce overall the emissions to the air resulting from electricity consumption in Ontario and produced in, or transported through, Ontario for other markets. IPPSO/CEEA strongly supports Ontario's introducing regulations that would allow emissions reductions trading as a means of market-based economic compliance, and to facilitate the introduction of more efficient and cleaner technologies. They also support the government's efforts to date to ensure that green power labeling and marketing are parts of Ontario's new electricity market. The most environmentally preferable option for managing energy supply and demand is to avoid the needless generation of energy. It is important that the dialogue resume on proposed new environmental approvals process for electricity projects. An appendix has excerpts from the White Paper

2011-07-01

On May 5, 2011, the Ontario Waterpower Association hosted the emergent hydro workshop in Peterborough. In the course of the workshop, Fisheries and Oceans Canada presented the habitat management program in Ontario. Fisheries and Oceans Canada explained that their role is to protect water resources. The Fisheries Act was passed to manage fisheries and fish habitats in Canada and to protect them from harmful alteration, disruption or destruction. The policy for the management of fish was written to interpret the Fisheries Act and enhance the productive capacity of fish habitats. In addition, two other Acts were passed, the Species at Risk Act and the Canadian Environmental Assessment Act, designed to protect species from extinction and improve coordination of, and public access to EA information. This presentation highlighted the different existing policies aimed at protecting fisheries and fish habitats in Canada.

This report presented a comprehensive approach to energy conservation programming for the Fort William First Nation, located in Thunder Bay, Ontario. The report outlined the historical context of the relationship between the Canadian government and Aboriginal people. The Aboriginal community in Ontario was described with reference to the difference between First Nations population, Metis, and Inuit. Statistics on the Aboriginal population in Ontario was broken down. Different Aboriginal organizations as well as organizations serving Aboriginal peoples were identified and described. The report also described the political process and administrative protocol for energy conservation and energy efficiency. Energy conservation in the Aboriginal community was also explained. Last, the report provided several recommendations related to awareness and education; translation; incentives; delivery mechanisms; and pilot projects. The report concluded with an agreement to hold a provincial conference in Toronto on the issues raised in the report. The report concluded that an Aboriginal unit within the Bureau of Conservation of the Ontario Power Authority was envisioned to plan, develop, implement, manage and monitor the deliverables resulting from the report.

A workshop on seismic hazard assessment in southern Ontario was conducted on June 19-21, 1995. The purpose of the workshop was to review available geological and seismological data which could affect earthquake occurrence in southern Ontario and to develop a consensus on approaches that should be adopted for characterization of seismic hazard. The workshop was structured in technical sessions to focus presentations and discussions on four technical issues relevant to seismic hazard in southern Ontario, as follows: The importance of geological and geophysical observations for the determination of seismic sources; Methods and approaches which may be adopted for determining seismic sources based on integrated interpretations of geological and seismological information. Methods and data which should be used for characterizing the seismicity parameters of seismic sources. Methods for assessment of vibratory ground motion hazard. This document presents transcripts from recordings made of the presentations and discussion from the workshop. It will be noted, in some sections of the document, that the record is incomplete. This is due in part to recording equipment malfunction and in part due to the poor quality of recording obtained for certain periods.

Objective To understand the perspectives of Ontario parents regarding the advantages and disadvantages of adding influenza immunisation to the currently existing Ontario school-based immunisation programmes. Design Descriptive qualitative study. Participants Parents of school-age children in Ontario, Canada, who were recruited using a variety of electronic strategies (social media, emails and media releases), and identified as eligible (Ontario resident, parent of one or more school-age children, able to read/write English) on the basis of a screening questionnaire. We used stratified purposeful sampling to obtain maximum variation in two groups: parents who had ever immunised at least one child against influenza or who had never done so. We conducted focus groups (teleconference or internet forum) and individual interviews to collect data. Thematic analysis was used to analyse the data. Setting Ontario, Canada. Results Of the 55 participants, 16 took part in four teleconference focus groups, 35 in 6 internet forum focus groups and four in individual interviews conducted between October 2012 and February 2013. Participants who stated that a school-based influenza immunisation programme would be worthwhile for their child valued its convenience and its potential to reduce influenza transmission without interfering with the family routine. However, most thought that for a programme to be acceptable, it would need to be well designed and voluntary, with adequate parental control and transparent communication between the key stakeholder groups of public health, schools and parents. Conclusions These results will benefit decision-makers in the public health and education sectors as they consider the advantages and disadvantages of immunising children in schools as part of a system-wide influenza prevention approach. Further research is needed to assess the perceptions of school board and public health stakeholders. PMID:24902736

Typhoid fever is a significant contributor to infectious disease mortality and morbidity in low- and middle-income countries, particularly in South Asia. With increasing antimicrobial resistance, commonly used treatments are less effective and risks increase for complications and hospitalizations. During an episode of typhoid fever, households experience multiple social and economic costs that are often undocumented. In the current study, qualitative interview data from Kathmandu and surrounding areas provide important insights into the challenges that affect those who contract typhoid fever and their caregivers, families, and communities, as well as insight into prevention and treatment options for health providers and outreach workers. When considering typhoid fever cases confirmed by blood culture, our data reveal delays in healthcare access, financial and time costs burden on households, and the need to increase health literacy. These data also illustrate the impact of limited laboratory diagnostic equipment and tools on healthcare providers' abilities to distinguish typhoid fever from other febrile conditions and treatment challenges associated with antimicrobial resistance. In light of these findings, there is an urgent need to identify and implement effective preventive measures including vaccination policies and programs focused on at-risk populations and endemic regions such as Nepal. © The Author 2017.
