Air Quality Permits
Air pollution control in Washington is based on federal, state and local laws and regulations. The federal Environmental Protection Agency, the Department of Ecology (Ecology), and local clean air agencies, all regulate air quality. Ecology implements and enforces air quality regulations in counties without an air pollution control agency. Ecology also has jurisdiction over primary aluminum plants, pulp mills, vehicles, and vehicle-related sources. For contact information about the state's seven local clean air agencies and Ecology's regional offices, addresses, and telephone numbers, see Local Clean Air Agencies.
If you are located in one of the following counties, you have a local clean air agency: Benton, Clallam, Clark, Cowlitz, Grays Harbor, Island, Jefferson, King, Kitsap, Lewis, Mason, Pacific, Pierce, Skagit, Skamania, Snohomish, Spokane, Thurston, Wahkiakum, Whatcom, or Yakima. Please select the local air authorities link for information on air quality permits in your county. Local clean air agencies may implement and enforce most state regulations. All local agencies have their own regulations that may be more restrictive than those of Ecology. These more stringent regulations are not addressed in this guide.
Large new energy related resources, such as thermal/nuclear power plants, oil refineries, pipelines, etc., are under the jurisdiction of the Energy Facility Site Evaluation Council (EFSEC).
The list below contains Ecology air quality permit information and applications.
- Air Operating Permit: The operation of a major source of air contaminants.
- Air Quality Notice of Construction (NOC) Permit: Releasing pollution to the air from a new or modified business or industrial source, unless the source or activity has been exempted.
- Asbestos - Air Quality (Demolition / Renovation Notification Form): You must submit an asbestos demolition/renovation notification form any time you:
Before beginning any work, you must:
- Want to demolish any structure, including for the purpose of fire training, or
- Remove or abate Regulated Asbestos Containing Material (RACM) in an existing structure with at least 260 linear feet of RACM on pipes, 160 square feet of RACM on other facility components, or 35 cubic feet of RACM off of facility components where length or area could not be measured previously.
Guidance is available on the EPA Region 10 asbestos web page and at the other links listed below.
- Fill out the form.
