Air pollution in British Columbia


Air pollution in British Columbia

Air pollution is a concern in British Columbia (BC), Canada because of its effects on health and visibility. Air quality is influenced in BC by numerous mountain ranges and valleys, which complicate atmospheric pollution dispersion and can lead to high concentrations of pollutants such as particulate matter from wood smoke (especially during stagnant atmospheric conditions/ inversions).

Air quality in BC

Air quality in much of BC is good compared to many areas of North America. This is particularly true for cities in BC such as the Greater Vancouver area and Victoria, British Columbia.Fact|date=June 2007

Valley communities (e.g. Golden) may experience periods of poor air quality, particularly during stagnant atmospheric conditions. Two communities currently exceed the federal air quality standards; Prince George for particulate matter (PM2.5) and the community of Hope (in the Lower Frase Valley) for ozone. Other communities are close to the PM2.5 standard, such as Quesnel and Kamloops. Communities close to exceeding the standard for ozone include Chiliwack, Langley, Kamloops and others.Fact|date=June 2007

Hourly air quality monitoring results are available for the Lower Fraser Valley [http://www.metrovancouver.org/services/air/monitoring/Pages/airqualityindex.aspx] . Air quality information is available for the rest of the province [http://www.env.gov.bc.ca:8000/pls/aqiis/air.summary] from the Ministry of the Environment

The BC Lung Association produces an annual [http://www.bc.lung.ca/airquality/stateoftheair-report.html State of the Air Report] for BC. This report is a collaboration between the provincial, federal and regional governments responsible for air quality management in BC.

ources of air pollution

Sources of air pollution sources in British Columbia may be divided between those external to the province, such as transboundary pollution, and those internal to it; and between anthropogenic (man-made) sources and natural sources. External anthropogenic sources include combustion particles and gases from industrial sources in the province of Alberta or the U.S. state of Washington. Mount St. Helens has been a significant external natural source: although located entirely in the United States, its eruption created air pollution in parts of British Columbia.

Exhaust from internal combustion engines (mainly automobiles and trucks, as well as marine vessels in coastal waters) is a major internal anthropogenic source. Other human-caused sources include: Industrial, agricultural (e.g. manure spreading), commercial operations (e.g., dry cleaners and gas stations) and home heating appliances (furnaces, fireplaces).

"Background pollution" occurs in areas not directly affected by pollution sources.

Pollution law

The Canadian Constitution does not clearly specify the level of government that has responsibility for environmental protection in Canada. As such, pollution law in British Columbia is divided among local, regional, provincial, federal and international jurisdictions, each with its own focus and, at times, overlapping concerns. Legislation may be enacted at any of these levels.

Provincial air quality law

Provincial environmental regulation is largely contained in BC's [http://www.qp.gov.bc.ca/statreg/stat/E/03053_00.htm Environmental Management Act] , which [http://www.qp.gov.bc.ca/statreg/stat/E/03053_01.htm#section001 defines] air pollution as follows:: "pollution" means the presence in the environment of substances or contaminants that substantially alter or impair the usefulness of the environment.

Federal air quality law

Federal pollution law is largely embodied in the [http://laws.justice.gc.ca/en/C-15.31/ Canadian Environmental Protection Act] (CEPA) and its associated schedules. The act of scheduling a toxin under CEPA starts a [http://laws.justice.gc.ca/en/C-15.31/29533.html#rid-29558 process] of elimination or virtual elimination from the Canadian environment.

The [http://www.ec.gc.ca/pdb/npri/npri_home_e.cfm National Pollutant Release Inventory] indexes sources by pollutant and location.

Pollution law governing emissions from marine vessels is complicated; Transport Canada holds primary authority for regulating ship traffic in Canada, while the International Maritime Organization governs global shipping rules (including pollution from marine vessels). Environment Canada and other agencies are working to better understand and address this issue, which is increasingly important due to growing international trade.

Regional and municipal air quality law

Within the province, various Regional Districts and municipalities have enacted laws to control pollution. There are also area-based plans to manage pollution along geographic lines that recognize airsheds instead of political boundaries. This system is especially relevant to BC because of its mountainous topography. The BC Environmental Management Act recognizes airsheds and notes that managers under the Act "may give consideration" to them, but their full legal status is uncertain. Some plans have had a considerable effect, and this trend is likely to continue.

The Greater Vancouver Regional District (GVRD) has a clearly defined role in air pollution control and has delegated authority from the province (Montreal is the only other jurisdiction in Canada with this delegated authority). The Fraser Valley Regional District has delegated authority to plan but not manage air quality.

British Columbia is a participant in the [http://www.ccme.ca Canadian Council of Ministers of the Environment] (CCME), which includes processes for fine particulates and ground level ozone. Because BC generally has lower levels of pollution than the standards set by the Environmental Protection Act, the CI/KCAC ("Continuous Improvement" and "Keeping Clean Areas Clean") principles of the federal strategy is of special importance.

International law and treaties such as the Kyoto Accord further affect air pollution in BC.

The precautionary principle embodied in international agreements is gaining recognition in Canada and BC as a guide to interpreting pollution law.
