Permit Information 

The District’s permitting program provides a procedure for the review of new sources of air pollution, and the modification and operation of existing sources, through engineering evaluations and the issuance of permits. Any device or contrivance that may be a source of air contaminants or is intended to control or mitigate those air contaminants, has the potential to require a Permit to Operate from the Air District.

Permits allow the District to specify operating conditions consistent with our countywide clean air strategy and state air toxics requirements. Both large and small businesses need an Air District permit before they construct, change, replace, or operate any equipment and process that could cause air pollution including any equipment designed to reduce air pollution. A Permit to Operate is based on the Air District Rules 401 and Rule 501, and Health & Safety Code: Section 42300).

Permits are also required if an existing business transfers ownership, relocates, or otherwise changes their operation.

Please do not submit ANY forms with ANY payment without first contacting the Air District to verify that you actually need a permit. Reimbursing payments made in error is a lengthy process.
