The District is a regional agency, created by the state, that regulates stationary sources of air pollution within the Lake County Air Basin. These sources include industrial developments such as the Geysers Geothermal Power Generation as well as commercial businesses with air emissions such as mining operations and gasoline stations.

The main purpose of the LCAQMD is to enforce local, state, and federal air quality laws, rules and regulations in order to meet the Ambient Air Quality Standards (AAQSs), and protect the public from air toxics through local regulation, State ARB ATCM and Federal EPA NESHAP specific control regulations.

Funding is provided by state subvention, permit fees, fines, and grants. The District is self-supporting, and is not funded by property taxes. The LCAQMD pays overhead, rent, and other charges to the Lake County General Fund.

The District Board of Directors is the ex-officio County Board of Supervisors.
