The California Air Districts layer is a polygon shapefile coverage representing the California air pollution control and air quality management districts, as defined in federal and state law. See 40 CFR, Chapter I Section 81, et seq., and California Health and Safety Code, Section 40000 et seq. Shapefile coverage. This data layer shows the air district boundaries and their names as of March 2004. Projection: Teale Albers, NAD83, GRS 1980.
Air Districts are designated pursuant to federal and state statute. Air districts identify the local and regional authorities who have primary responsibility for control of air pollution from sources that are not motor vehicles. (Motor vehicles are the responsibility of the state Air Resources Board.)
