McGuinty Government Supports Legal Action Against EPA Ozone Standards TORONTO, July 29 /CNW/ - NEWS Ontario is continuing its opposition to new, weak U.S. ozone standards by supporting legal action against the U.S. Environmental Protection Agency (EPA). On Friday, Ontario advised the U.S. Court of Appeals for the District of Columbia Circuit in Washington, D.C. that it will file an amicus brief in the ozone standards case now before the court. The brief will lay out Ontario's concerns about the health and environmental impacts of ozone and transboundary air pollution. Ontario's brief will support legal action brought by 14 states, two cities and five non-governmental health and environment organizations against the EPA to seek stricter standards. The court has not set a date for when the brief will be filed. The EPA has set new ambient air quality standards for ozone of 75 parts per billion (ppb), reduced from the previous level of 80 ppb. The Canada-Wide Standard for ozone is 65 ppb. In September 2007, Ontario submitted comments to the EPA, urging it to adopt standards at least as stringent as the Canada-Wide Standard. However, in March 2008, the EPA adopted the weaker 75 ppb standard, a decision contrary to the unanimous advice of the agency's own Clean Air Scientific Advisory Committee. The U.S. interests supported by Ontario in the call for more stringent ozone standards are: New York, California (plus the California Air Resources Board), Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New Mexico, Oregon, Pennsylvania, Rhode Island, District of Columbia and City of New York. The non-governmental organizations are the American Lung Association, Environmental Defense Fund, Natural Resource Defense Council, National Parks Conservation Association and Appalachian Mountain Club. QUOTES "Ground-level ozone is a serious threat to our health and our environment," said Environment Minister John Gerretsen. "We simply want the U.S. to adopt stronger ozone standards to better protect citizens on both sides of the border." "People living with asthma and chronic lung disease are more at risk from exposure to ground level ozone than the general population. However, even healthy people can be affected by the smog episodes experienced in Ontario," said George Habib, president and CEO of the Ontario Lung Association. "Given that U.S. sources contribute about 50 per cent of Ontario's smog, Ontario's efforts to improve its air quality need to be supported by similar U.S. actions." "The American Lung Association welcomes Ontario in the fight to protect us all from the dangers of ozone air pollution," said Bernadette Toomey, President and Chief Executive Officer, American Lung Association. "Ozone smog knows no boundaries. Americans and Canadians alike suffer from the life-threatening harm from this pollution. All of us need the safeguards of truly protective ozone standards." << QUICK FACTS - There is no safe level of smog. Ground-level ozone, a major component of smog, can result in significant adverse health effects for the elderly, children and those with cardiovascular or respiratory illnesses. It also causes damage to crops, vegetation and forested areas. - The brief is called an amicus brief, short for Amicus Curiae, or Friend of the Court. - Ontario wants stronger standards in the U.S. in order to reduce ozone levels here. On average, transboundary air pollution is responsible for about half of Ontario's smog.

Colourless and odourless, ozone (O3) is an extremely reactive gas molecule composed of three oxygen atoms. Ozone forms in chemical reactions in the upper atmosphere when nitrogen oxides (NOx) and volatile organic compounds (VOCs), come into contact with both sunlight and heat. Sources of Ozone Ozone is present in two areas of the atmosphere and plays two roles. Ozone formed naturally in the atmosphere (the "good" ozone) protects life from the sun's damaging ultraviolet rays. At ground level, however, ozone acts as an invisible air pollutant that is harmful to humans, animals, plants and man-made materials. Ground-level ozone is one of the main ingredients of smog. It is created when gases such as nitrogen oxides (NOx) react with volatile organic compounds (VOCs) in combination with sunlight and heat. This is why smog is more of a problem on hot summer days. Nitrogen oxides are produced by burning fossil fuels such as coal, oil, gas, and diesel in motor vehicles, industries, power plants and homes. VOCs include carbon-containing gases that are created when gasoline and solvents are burned. Studies show that every major Canadian urban centre has levels of ground-level ozone that are high enough to pose health risks. Ontario is disproportionately affected because of it geographical location, downwind of the major U.S. sources of pollutants. Ozone levels typically rise between May and September due to a combination of higher temperatures, more sunlight, and stagnant air masses, leading to significant areas of the province having unhealthy levels of the gas. Due to the transboundary nature of the gas, up to 90 per cent of smog-causing air pollutants come from sources outside of the province on elevated ozone days. As a result, 19 of 20 monitored sites in Ontario cannot currently meet the Canada-Wide Standards for ozone. Effects on Health and the Environment Studies show a wide variety of effects caused from ozone exposure. Short-term exposure can result in eyes nose and throat irritation, coughing and headaches. Exposure to high levels can result in reduced lung function. Ozone is a major contributor to asthma and it can worsen the existing symptoms of asthma. The American Lung Association has identified the following immediate problems attributed to ozone: << - shortness of breath - chest pain when inhaling deeply - wheezing and coughing - increased susceptibility to respiratory infections - inflammation of the lungs and airways - increased risk of asthma attacks - increased need for medical treatment and hospital admission for people with lung diseases, like asthma or chronic obstructive pulmonary disease (COPD). >> Children, the elderly and people with respiratory and heart problems, asthma and lung disease are at the highest risk. Also at risk are healthy adults exercising and working outdoors for long periods of time. Exposure to ozone can lead to increased hospital admissions and even premature death. In June 2008, the Ontario Medical Association (OMA) estimated that air pollution is a contributing factor in almost 9,500 premature deaths annually in Ontario. In a 2005 report, the OMA also blamed air pollution for nearly 17,000 hospital admissions and almost 60,000 emergency rooms visits. MOE, in its 2005 report on transboundary air pollution, estimated health costs at $6.6 billion. Effects on Vegetation Ozone is toxic to plants and causes crop loss each year in Ontario, including noticeable leaf damage in many crops, garden plants and trees. The 2005 Transboundary Air Pollution in Ontario report indicated that air pollution costs Ontario's economy $3 billion each year in environmental damages. United States Environmental Protection Agency reports have shown that ozone has the following effects on plant life: << - interfering with the ability of sensitive plants to produce and store food, making them more susceptible to certain diseases, insects, other pollutants, competition and harsh weather; - damaging the leaves of trees and other plants, negatively impacting the appearance of urban vegetation, national parks, and recreation areas; and - reducing crop yields and forest growth, potentially impacting species diversity in ecosystems. Because these impacts directly affect plant life, the economy also suffers in both the agricultural and forestry sectors. Additional costs to the Ontario's economy include damage to buildings and infrastructure. ------------------------------------------------------------------------- ontario.ca/environment-news Disponible en français >>
