California Geothermal Air Quality Assessment(15-CA)

In California, developers may be required to obtain multiple air quality permits for their project. One project may necessitate both an Air Quality Permit to Construct and an Air Quality Operating Permit.

Developers must obtain an Air Quality Authority to Construct Permit from the local Air Pollution Control District (APCD) or Air Quality Management District (AQMD) before beginning construction if their project will result in emission of air pollutants from a stationary source. Developers may be exempt from Authority to Construct requirements by the applicable district, so they should consult with the district to determine if an exemption applies. Developers must submit an application to the local district for review. Each district maintains their own application. The local district will develop a preliminary decision, provide public notice, and allow the public to comment. The local district and local county may impose conditions on the Authority to Construct.

Developers must obtain an Air Quality Operating Permit from the local Air Pollution Control District (APCD) or Air Quality Management District (AQMD) if they are operating a facility that emits pollutants. Each local APCD or AQMD has specific procedures for issuing the Operating Permit, so developers should consult with the applicable district for specific requirements. Generally, developers will be required to submit an application for review. In most districts, an inspection of the facility will also be required.
