To implement the state Clean Air Act, the Legislature delegates authority to the Department of Ecology to establish air quality and emissions standards and to prohibit emissions to the outdoor atmosphere of odors, dust, smoke, fumes, gas, and other emissions. The Department of Ecology is charged with enforcing the established air quality and emission standards throughout the state. The Department of Ecology's rules prohibit a person from causing or allowing the installation or use of any means that conceals or masks an emission of an air contaminant that would otherwise violate rules adopted to implement the Clean Air Act.

The state Liquor and Cannabis Board issues licenses to qualified individuals and businesses including a marijuana producer license, a marijuana processor license, and a marijuana retailer license.
