  • ABOUT THE COMPANY

    • South Coast Air Quality Management District
    • South Coast Air Quality Management District

    South Coast Air Quality Management District (South Coast AQMD) is one of the largest and most technologically sophisticated environmental regulatory agencies in the nation.  We serve a four-county region that includes all of Orange County and the urban portions of Los Angeles, Riverside, and San Bernardino counties, home to more than 17 million people.  South Coast AQMD's headquarters is located in Diamond Bar, 30 miles east of downtown Los Angeles, at the junction of the 57 and 60 freeways.  With a highly diverse "Clean Air Team" of over 750 employees, an annual budget of $170.9 million, and a state-of-the art air quality laboratory, our mission is to ensure clean air and a healthful environment.

     

    Mission

    To clean the air and protect the health of all residents in the South Coast Air District through practical and innovative strategies.

    What is the South Coast AQMD?

    South Coast AQMD is the regulatory agency responsible for improving air quality for large areas of Los Angeles, Orange, Riverside and San Bernardino counties, including the Coachella Valley.  The region is home to more than 17 million people–about half the population of the entire state of California.

    Despite significant improvements to air quality, more work needs to be done to protect public health through innovative and practical strategies. Air pollution can cause or worsen many health problems, including asthma attacks, heart disease, certain types of cancers and premature death. South Coast AQMD has been at the forefront of the nation’s air pollution reduction efforts for more than eight decades.

    What South Coast AQMD Does

    Pie Graph of Sources of Ozone-Forming Pollution

    South Coast 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. There are about 28,400 such businesses operating under South Coast AQMD permits. 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 80% 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 South Coast AQMD.

    How South Coast AQMD Controls Pollution

    Bar Graph of Progress in Reducing Ozone Pollution 1976-2009

    South Coast AQMD develops and adopts an Air Quality Management Plan, which serves as the blueprint to bring this area into compliance with federal and state clean air standards.  Rules are adopted to reduce emissions from various sources, including specific types of equipment, industrial processes, paints and solvents, even consumer products.  Permits are issued to many businesses and industries to ensure compliance with air quality rules. South Coast AQMD staff conducts periodic inspections to ensure compliance with these requirements. 

    The test of whether these efforts are working is the quality of the air we breathe.  South Coast AQMD continuously monitors air quality at 38 locations throughout the four-county area. This also allows South Coast AQMD to notify the public whenever air quality is unhealthful.

    South Coast AQMD’s Sources of Revenue

    To meet its financial need, the South Coast AQMD utilizes a system of evaluation fees, annual operating fees, emission fees, Hearing Board fees, penalties/ settlements and investments that generate approximately 73% of South Coast 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.

    Progress So Far

    Air quality in this area has continually improved despite an enormous increase in population and cars. For example, maximum levels of ozone, one of our worst smog problems, have been cut to less than one quarter of what they were in the 1950s, even though today we have nearly three times as many people and four times as many vehicles.

    In recent decades, we have eliminated Stage I smog alerts, which used to occur 100-120 times a year. We have not reached Stage II levels since the 1980s.

    The Job Ahead

    The clean air effort still has a long way to go. In 2005, the federal 1-hour standard was replaced by a stricter 8-hours standard that was further strengthened in 2008. Even though recent years have been the cleanest on record, our air in the South Coast Air Basin still exceeded the federal health 8-hour standard for ozone on 113 days in 2009. Maximum levels are almost twice as high as the federal standard for clean air.

    State and federal law requires this area to meet existing clean air standards by the year 2015 for annual PM 2.5; and by 2023 for the 8-hour average ozone standard. However, tougher federal air quality standards for particulates and ozone issued in 2006 and 2008 require reductions above and beyond those already planned.  South Coast AQMD estimates it will take until at least 2020 to meet the new 24-hour average particulate standard, and until 2030 to meet the new ozone standard.  This may seem like a long time to continue to live with smog. But the cleanup effort is enormous.  Even though we already have the strictest pollution control requirements in the nation, we still have to reduce some types of pollution by up to 90% if we are to rid the area of smog.

    The war on smog began in this region more than a half century ago.  With continued commitment and sensitivity to the impacts of efforts to control smog, residents can be assured that public health standards for air quality will be achieved.
