South Coast Air Quality Management District - South Coast AQMD

South Coast Air Quality Management District - South Coast AQMD Improving air quality in Los Angeles, Orange County, Riverside and San Bernardino counties There are about 28,400 such businesses operating under AQMD permits.

AQMD is responsible for controlling emissions primarily from stationary sources of air pollution. These can include anything from large power plants and refineries to the corner gas station. Many consumer products are also considered stationary sources; these include house paint, furniture varnish, and thousands of products containing solvents that evaporate into the air. About 25% of this area's ozone-forming air pollution comes from stationary sources, both businesses and residences. The other 75% comes from mobile sources--mainly cars, trucks and buses, but also construction equipment, ships, trains and airplanes. Emission standards for mobile sources are established by state or federal agencies, such as the California Air Resources Board and the U.S. Environmental Protection Agency, rather than by local agencies such as the AQMD.
