The South Coast Air Quality Management District, also using the acronym SCAQMD, formed in 1976, is the air pollution agency responsible for regulating stationary sources of air pollution in the South Coast Air Basin, in Southern California. The separate California Air Resources Board is responsible for regulating mobile sources (e.g. vehicles) in the air basin.

Basin geography[edit]

The SCAQMD includes all of Orange County; and the non-desert regions of Los Angeles and Los Angeles County, San Bernardino County, and Riverside County.

The South Coast Air Basin area encompassed by the SCAQMD amounts to about 10,750 square miles (27,850 square kilometres) and is the second most populated area in the United States. This area has a severe problem with smog, and the SCAQMD has been a leader in the nation's efforts to reduce air pollution emissions. The main office of the SCAQMD is located in the city of Diamond Bar.

Operations[edit]

The SCAQMD 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 SCAQMD staff conducts periodic inspections to ensure such compliance.

The SCAQMD's rules apply to businesses ranging from large oil refineries and power plants to gasoline (petrol) fueling stations and dry cleaning plants. There are about 30,000 such businesses operating under SCAQMD permits. In general, the SCAQMD is limited to establishing rules for regulating stationary sources. Emission standards for mobile sources (automobiles, trucks, buses, railroads, airplanes and marine vessels) are established the U.S. Environmental Protection Agency and the California Air Resources Board.

Air quality monitoring network[edit]

The SCAQMD also operates an extensive network of air quality monitoring stations (about 40 stations) and issues daily air quality forecasts. The forecasts are made available to the public through newspapers, television, radio, faxed messages to schools, the SCAQMD's internet website, and a toll-free Smog Update telephone line.[1][2]

Air quality and air pollution dispersion modeling[edit]

The air quality modeling activities of the SCAQMD are one of the functions of the Planning, Rule Development and Area Sources section. That section is also responsible for oversight and commenting upon air pollution dispersion modeling[3] studies performed as part of any environmental impact studies that may be reviewed by or requested by the SCAQMD. The models that may be utilized include:[4]

Organization[edit]

The SCAQMD has a Governing Board of 12 members. Nine of the members are county supervisors and city council members. The remaining three are appointed by California state officials. The chief Executive Officer of the SCAQMD reports to the Governing Board and the following departments report to the Executive Officer:

Funding for the SCAQMD[edit]

The AQMD utilizes a system of evaluation fees, annual operating fees, emission fees, Hearing Board fees, penalties/ settlements and investments that generate approximately 73% of AQMD’s revenue. The remaining 27% of its revenue is from federal grants, California Air Resources (CARB) subvention funds, and California Clean Air Act Motor Vehicle fees.
