Directory of the California Local Air Pollution Districts
In addition to the California Air Resources Board, air pollution in this state is addressed at the local level
by one of 35 air pollution districts. Each district establishes and enforces
air pollution regulations in order to attain and maintain all state and federal ambient air quality standards.
The districts control emissions from and permit stationary sources of air pollution. They also implement transportation
control measures for their respective regions.
Each district adopts its own rules and regulations to combat the particular air quality problems within its
region. The types of sources that districts regulate vary from district to district. Depending on the particular
problems of a region, some of the types of air pollution sources that might be regulated include: manufacturers,
power plants, refineries, gasoline service stations, and auto body shops.
It is the ultimate responsibility of business owners to determine if their business is subject to local air
pollution laws and consequently must have an air permit. The district is there to help you make this determination
and to help you do it in the easiest way possible.
