District Rules Database Disclaimer

This page last reviewed April 30, 2018

This District Rules Database includes rules from all 35 air districts in either HTML or PDF formats. If you have any questions with respect to the districts, please contact them directly.


Infrequently, The California Air Resources Board (CARB) tries to keep the DRDB current. However, we cannot ensure this. CARB updates the database as best as possible. The districts help us with this. If you are in doubt, review the actual district rule version. Note that the rule shown may not be in the applicable State Implementation Plan (SIP). If you need information regarding the applicable SIP, contact the district directly. You may also contact Cynthia Allen of the United States Environmental Protection Agency at (415) 744-1189.

Please direct your questions to Carol Sutkus at (916) 322-1229. CARB appreciates your comments and suggestions.
