The Mission of the Monterey Bay Unified Air Pollution Control District is to Protect the Public Health while Balancing Economic and Air Quality Considerations.

The air district in this region was created by the Monterey County Board of Supervisors in 1965. Three years later, Santa Cruz County joined Monterey County to form a two-county unified district. In 1969, the state designated the three counties of Monterey, San Benito, and Santa Cruz as the North Central Coast Air Basin, a single region sharing the same air pollution problems. A year later, the federal Clean Air Act formalized the responsibility of state and local governments to manage air quality in their regions. On July 1, 1974 Monterey and Santa Cruz County Unified Air Pollution Control District merged with the San Benito County Air Pollution Control District to form the Monterey Bay Unified Air Pollution Control District (hereinafter, the District).

The District is governed by an 11-member Board of Directors appointed from the elected governing bodies of our member jurisdictions. Six Board members are county supervisors; five are mayors or city council members. The number of representatives on the Board from each of the member cities and counties is based on the relative population in each county. The Air Pollution Control Officer is appointed by the Board and serves as Executive Director of the District. The District Counsel is also appointed by the Board.

The Board of Directors appoints the District's Advisory Committee to advise and assist the Board and District staff. Each Board member appoints two representatives to the Committee.

The Board of Directors appoints five citizens to the District's Hearing Board, which is comprised of two public members, a medical professional, a legal professional, and an engineer. The Hearing Board is a quasi-judicial body.

As required by the California Clean Air Act and Amendments (HSC Section 40910 et seq.) and the Federal Clean Air Act and Amendments (42 U.S.C. Section 7401 et seq.) the District is responsible for air monitoring, permitting, enforcement, long-range air quality planning, regulatory development, education and public information activities related to air pollution. California Health and Safety Code Sections 39002, et seq. and 40000, et seq. require local districts to be the primary enforcement mechanism for air pollution control. Districts must have rules and regulations for the implementation and enforcement for the attainment and maintenance of federal and state ambient air standards.
