As part of the Air District’s responsibility to meet state and federal clean air standards, the District adopts rules and issues permits that require compliance with these standards. Permits allow the District to specify operating conditions consistent with our countywide clean air strategy and state air toxics requirements. Some of the businesses required to hold permits are power plants, gas stations (retail and non-retail), dry cleaners, auto body shops, printers, rock crushers, screening operations, portable equipment, electrical generators, and large and medium size boilers.
Permits provide information on the equipment in use and the air pollution devices used to control the air pollution caused through operations. 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. Permits are also required if an existing business transfers ownership, relocates, or otherwise changes their operation. The District’s Frequently Asked Questions has additional information on permitting. Applications are available on the Forms, Fees and Facts web page.
Businesses can apply for emission reduction credits. To determine if your business can meet the criteria for emission reduction credits, contact the District Engineer at 530-745-2324.

The Air Resources Board adopted an air toxic control measure (ATCM) for stationary diesel engines. Each local air district implements the ATCM. For more information contact Air District staff at 530-745-2330 or at the Diesel ATCM web page.
Permit fees cover our cost to review applications, issue permits, and ensure compliance. Different fees apply to different types of permits and equipment. The Fee Tables in the District’s Fee Schedule are subject to annual adjustment, July 1st, to reflect increases in the California Consumer Price Index (CPI).
