Permit Fee Rule
Learn about the Air District’s permitting, registration, asbestos, open burn and other programs requiring either fees or notifications.
The Air District is responsible for the issuance of air quality permits for stationary equipment in the Bay Area and the management of the resulting air emissions (pollutants). Nearly all stationary equipment that emits to the atmosphere requires an Air District permit. An air quality permit is a document that gives the permit holder authorization to build equipment and/or to operate that equipment. Each project is evaluated before a business can build and operate their equipment to ensure that all air quality requirements are met.
The program also manages an air emissions inventory from all permitted equipment. The inventory is used to track the level of air emissions and to make future decisions to reduce those emissions by tightening Air District rules.
Here are common permit and approval documents that the Air District issues:
Authority to Construct (A/C) - This is a pre-construction permit that is issued before equipment is installed. An A/C may require the permit holder to meet certain conditions before operation can begin.
Permit to Operate (P/O) - This permit allows the holder to operate (use) all equipment or activities listed on the permit.
Certificate of Registration - This type of permit is given to specific types of equipment or activities that are smaller in nature.
Certificate of Exemption - Upon request, this type of document is issued if the specific type of equipment or activity does not require an Air District permit.
Approval Letter for Asbestos for Demolition/Renovation, “Job Number” - A letter of approval that will include a Job Number (J#) is issued as proof of notification.
Approval Letter for Naturally Occurring Asbestos Activity - A letter of approval is issued after your asbestos dust mitigation plan (ADMP) is approved.
Certificate for Emission Reduction Credits (ERCs) - This certificate allow companies to use or sell “banked” emissions when emissions from other projects must be offset.
Major Facility Review (Title V) Permit - This is a federal operating permit that is issued to facilities that have the ability to produce large amounts of air pollutants.
Owners of the following types of equipment may be eligible to apply for a renewable registration certificate instead of a permit (registration fees vary, depending on equipment type):
The following activities require notification and payment of fees prior to starting any work.
Open Burn Authorization or Allocation - This notification is required for allowable fire types prior to starting any burning.
The following activities require notification only prior to starting any work:
Soil Excavation Notification - This notification must be postmarked/submitted at least 5 days prior to excavation of soil contaminated with organic compounds.
