Clean Air Act permitting in California is the shared responsibility of the California Air Resources Board (CARB), its 35 air pollution control agencies (districts) and EPA Region 9. Generally, CARB plays an oversight role for permitting and does not issue any pre-construction or operating permits. However, that state agency provides significant support to agencies that need permitting assistance. Below are links to district information maintained on CARB's website, as well as a link to local district rules approved by EPA into the California State Implementation Plan (SIP) and the Federally Approved Title V program.

California SIP-Approved Permitting Programs

Air Pollution Control Agencies in California submit portions of their locally adopted rules through the California Air Resources Board to EPA for approval to meet federal requirements. Thus, state and local air agencies may have either more rules than what is submitted for SIP approval. In addition, some agencies make changes to their rules that may not have been submitted for approval into the SIP or have yet to be acted on by EPA if submitted into the SIP. Below is a link to the California SIP approved rules. As mentioned above, these rules may differ from the list of current rules in each of the 35 Air Distiricts. For purposes of federal enforce-ability, the EPA approved rules must be used.

Similar to State Implementation Plan Rules, in California title V program rules are submitted to EPA for approval to meet federal requirements under 40 CFR part 70.  Below is a table with links to the federally approved Operating Permit Programs for California Agencies.

In addition, as part of its oversight responsibilities, EPA Region 9 has conducted Title V program evaluations for the largest permitting authorities in California.
