The Bay Area Air Quality Management District (BAAQMD) is a government agency tasked with regulating air quality in the Bay Area of Northern California. The agency was established in 1955 as a result of concern about air pollution caused by industrial operations, transportation, and population growth. The BAAQMD’s primary function is to develop and enforce regulations aimed at curbing air pollution, including emissions from vehicles, stationary sources, and other sources of hazardous emissions. The agency is also involved in monitoring air quality, providing education and outreach to the public, and collaborating with other agencies and organizations to improve air quality. The BAAQMD is governed by a 24-member Board of Directors, made up of elected officials from the nine counties in the Bay Area, and civilian members appointed by the region’s mayors. The agency’s headquarters are located in San Francisco, with satellite offices throughout the region. The BAAQMD’s efforts have resulted in significant improvements in air quality in the Bay Area over the past several decades. Despite ongoing challenges related to population growth, transportation, and climate change, the agency remains committed to protecting public health and the environment by reducing air pollution.
