The regional planning agency in the San Francisco Bay area working to help solve problems in areas such as land use, housing, environmental quality, and economic development. ADT Average Daily Traffic ALUC Airport Land Use Commission APCD Air Pollution Control District AQMD Air Quality Management District ARB Air Resources Board AST Aboveground Storage Tank ASTM American Society for Testing and Materials BAAQMD Bay Area Air Quality Management District. A nine-county regional air district created under the provisions of the California Health and Safety Code Section 40200. It consists of nine member counties: all of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, and Santa Clara counties, and the southern portions of Solano and Sonoma counties. The BAAQMD is responsible for the developing the overall attainment strategy for its respective geographic area (see SFBAB above) and has the authority to regulate stationary sources, some area sources, and some aspects of mobile sources.

The basic federal air pollution control statute first passed in 1963, following a 1955 federal statute authorizing research and technical assistance. The 1965 and 1967 amendments began automobile and stationary source standards. The most recent amendments of the CAA were passed in 1990. CAAQS California Ambient Air Quality Standards CAG California Association of Governments CAP Clean Air Plan CARB or ARB California Air Resources Board. The state's lead air quality agency consisting of an eleven-member board appointed by the Governor. CARB is responsible for attainment and maintenance of the state and federal air quality standards, and is fully responsible for motor vehicle pollution control. It oversees county and regional air pollution management programs. Cal/EP A California Environmental Protection Agency. The state agency established in 1991 for unifying environmental activities related to public health protection in the State of California. The Cal/EP A boards, departments, and offices are directly responsible for implementing California environmental laws, or playa cooperative role with other regulatory agencies at regional, local, state, and federal levels. There are six boards, departments, and offices under the organization of Cal/EP A including the California Air Resources Board (ARB), California Integrated Waste Management Board (IWMB), State Water Resources Control Board (SWRCB) and its nine Regional Water Quality Control Boards (RWQCB), Department of Pesticide Regulation (DPR), Department of Toxic Substances Control (DTSC), and Office of Environmental Health Hazard Assessment (OEHHA). Caltrans California Department of Transportation CCAA California Clean Air Act. The state law that was passed in 1988 to provide the basis for air quality planning and regulation independent of federal regulations. A major element of the CCAA is the requirement that local air districts in violation of the CAAQS must prepare attainment plans that identify air quality problems, causes, trends, and actions to be taken to attain and maintain California's air quality standards by the earliest practicable date.

Chemicals that cause serious health and environmental effects. Health effects include cancer, birth defects, nervous system problems, and death due to massive accidental releases. Hazardous air pollutants are released by sources such as chemical plants, dry cleaners, printing plants, and motor vehicles (cars, trucks, buses. etc.).
