    The South Coast Air Quality Management District, also using the acronym South Coast (AQMD), formed in 1976, is the air pollution agency responsible for regulating stationary sources of air pollution in the South Coast Air Basin and the Coachella Valley portion of the Salton Sea 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

    The South Coast AQMD includes all of Orange County; and the non-desert regions of Los Angeles County, San Bernardino County, and Riverside County including the Coachella Valley.

    The South Coast Air Basin area encompassed by the South Coast AQMD 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 South Coast AQMD has been a leader in the nation's efforts to reduce air pollution emissions. The main office is located in the city of Diamond Bar.

    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 refineries and power plants to 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 California Air Resources Board.

    Air quality monitoring network

    South Coast AQMD 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, its award-winning smartphone application, social media, its website, and a toll-free Smog Update telephone line.

    Air quality and air pollution dispersion modeling

    The air quality modeling activities of the South Coast AQMD 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 studies performed as part of any environmental impact studies that may be reviewed by or requested by South Coast AQMD. The models that may be utilized include:

    Governing board

    South Coast AQMD has a Governing Board of 13 members. Ten of the members are county supervisors and city council members. The remaining three are appointed by California state officials. Current members of the Governing Board include:

    • Ben Benoit (Chair), Riverside County cities
    • Vanessa Delgado (Vice Chair), California State Senate Rules Committee appointee
    • Lisa Bartlett, Orange County Supervisor
    • Nithya Raman, Los Angeles City Council
    • Michael A. Cacciotti, Eastern Los Angeles County Cities
    • Gideon Kracov, Governor's appointee†
    • Sheila Kuehl, Los Angeles County Supervisor
    • Larry McCallon, San Bernardino County cities
    • Veronica Padilla-Campos, California State Assembly Speaker appointee
    • V. Manuel Perez, Riverside County Board of Supervisor
    • Rex Richardson, Western Los Angeles County cities
    • Carlos Rodriguez, Orange County cities
    • Janice Rutherford, San Bernardino County Supervisor

    †South Coast AQMD member to the California Air Resources Board

    The representative for Orange County cities is chosen by the 34 members of the Orange County City Selection Committee. Appointment requires both a majority vote of the committee and a majority vote when weighted by population. In November 2015, Republicans blocked reappointment of Santa Ana Mayor Miguel Pulido, a Democrat, to the board, voting to replace him with Republican Lake Forest Councilman Dwight Robinson.

    The chief Executive Officer of the South Coast AQMD reports to the Governing Board. The following departments report to the Executive Officer:

The remaining 27% of its revenue is from federal grants, California Air Resources (CARB) subvention funds, and California Clean Air Act Motor Vehicle fees.
