District Rules Database

This page last reviewed December 16, 2014

California's local air pollution control districts (APCD's) and air quality management districts (AQMD's) are now providing the California Air Resources Board with electronic versions of their district rules which regulate stationary sources in California. Ultimately, the quality of this database depends upon districts; please read our disclaimer.

You may access a list of districts for viewing and downloading district rules and regulations.

If you know a city name or ZIP code but do not know its associated district, please go to our district look-up by ZIP code, city or by county Database.

Included below are links to rule development resources that district and ARB rule development staff should find useful.
