Air Quality and Odor Controls

Air Quality and Odor Controls Requirements
In the State of Washington, regional air quality agencies and Washington State Department of Ecology regulate air quality, based on the county involved (see the list below). Because the production and processing of marijuana are sources of both odors and volatile organic compounds (VOCs) which can impact air quality and cause offsite nuisance, processors and producers are subject to air quality requirements. These requirements include, but are not limited to, air permits, registration program and fees. In addition, burning marijuana and the waste associated with the plant is not allowed.

If you are producing or processing marijuana and located in King, Kitsap, Snohomish or Pierce County, you are required to obtain an Order of Approval (often referred to as a permit) from the Puget Sound Clean Air Agency.

Please contact the appropriate air quality agencies listed below for more information.
