The Great Basin Unified Air Pollution Control District is a California regional government agency that works to protect the people and the environment of Alpine, Mono and Inyo Counties from the harmful effects of air pollution.

Inyo, Mono and Alpine Counties joined together in 1974 in a joint powers agreement to form the Great Basin Unified Air Pollution Control District, which covers the Great Basin Valleys - Air Basin in California.

GBUAPCD's purpose is to enforce federal, state and local air quality regulations and to ensure that the federal and state air quality standards are met in the District. These standards are set to protect the health of sensitive individuals by restricting how much pollution is allowed in the air.

To meet these standards GBUAPCD enforces those federal laws delegated to us, state laws on stationary sources of pollution, and pass and enforce our own regulations as they become necessary.
