The Northern Sonoma County Air Pollution Control District (NSCAPCD) is one of 35 California air districts established to regulate the emissions of air pollution from "stationary sources" that could be detrimental to the health, safety, and welfare of the public. The District's legal mandate originates from the federal Clean Air Act and California Health and Safety Code, and our oversight agencies are the federal Environmental Protection Agency and the California Air Resources Board. Our local rules and regulations are adopted by the District Board of Directors.
The NSCAPCD is the local air pollution district for the northern and western parts of Sonoma County. If you are within Sonoma County but are not within the District area, please contact the Bay Area Air Quality Management District at (415) 771-6000 or visit their website at www.baaqmd.gov .
