Emission Reduction Requirements
Canada estimates that by 2010, annual NOx emissions in the Canadian transboundary region will be reduced by 44 percent from 1990 levels.
- Aggressive annual caps by 2007 of 39 kilotonnes (kt) of nitrogen dioxide (NO2) emissions from fossil-fuel power plants in central and southern Ontario and 5 kt of NO2 in southern Quebec, aligned with U.S. standards year round.
- New stringent emission reduction standards regulated to align with the United States to reduce NOx and VOCs from vehicles and fuels, including cars, vans, light-duty trucks, off-road vehiles, small engines, diesel engines, and fuel.
- Measures required to attain the Canada-Wide Standard for Ozone to address NOxemissions from industrial boilers and to address VOC emissions from solvents, paints, and consumer products.
The United States estimates that by 2010, NOx emissions in the U.S. transboundary region will be reduced by 36 percent from 1990 levels year round, and by 43 percent from 1990 levels during the ozone season (May - September).
- The NOx emission reduction program, known as the NOx SIP Call, is expected to reduce summertime NOx emissions in the U.S. transboundary region by about 35 percent in 2007. EPA expects that this will be achieved by a more than 70 percent reduction in summertime emissions from power plants and major industrial sources.
- NOx and VOC reductions are associated with existing U.S. vehicle and fuel quality rules and standards for new and modified stationary sources. VOC reductions are associated with standards for stationary sources of hazardous air pollutants, consumer and commercial products, architectural coatings, and automobile repair coatings.
- Report ambient air quality within 500 km (310 miles) of the border beginning in 2002.
- Report annual emissions from major source categories beginning in 2004.
- Improve public access to information on emissions and air quality.
- Develop joint analyses on ground-level ozone and precursors
