Operations

South Coast AQMD develops, adopts and implements an Air Quality Management Plan for bringing the area into compliance with the clean air standards established by national and state governmental legislation. Air quality and permissible air pollutant emission "rules" are promulgated to reduce emissions from various sources, including specific types of equipment, industrial processes, paints, solvents and certain consumer products. Permits are issued to the pertinent industries and businesses to enforce compliance with the air quality and emission rules, and South Coast AQMD staff conducts periodic inspections to ensure such compliance. South Coast AQMD's rules apply to businesses ranging from large Oil refinery, oil refineries and power plants to Filling station, gasoline (petrol) fueling stations and dry cleaning plants. There are about 30,000 such businesses operating under South Coast AQMD permits. In general, the agency is limited to establishing rules for regulating stationary sources. Emission standards for mobile sources (automobiles, trucks, buses, railroads, airplanes and marine vessels) are established by the U.S. Environmental Protection Agency and the
