The Washington Clean Air Act.
The Washington Clean Air Act (Act) regulates outdoor air pollution. The Act defines "air pollution" as the "presence in the outdoor atmosphere of one or more air contaminants in sufficient quantities and of such characteristics and duration as is, or is likely to be, injurious to human health, plant or animal life, or property, or which unreasonably interfere with enjoyment of life and property."
Air pollution control regulations address emissions of air contaminants that injure health or unreasonably interfere with enjoyment of life and property. Enforcement authority for the Act is handled either by the Department of Ecology or by one of the seven regional clean air agencies within Washington, depending on the county in which the source is located.
A person may file a complaint about an odor via a regional clean air agency or via the Department of Ecology, depending on the county in which the odor is located.
Some activities, such as certain agricultural activities and particular forms of silvicultural burning, are exempt from certain provisions of the Act, provided they satisfy criteria set forth in the Act.
The Clean Air Act's (Act) definition of "air pollution" is amended to provide that, for purposes of the Act, "enjoyment of life and property" may include a person's use or enjoyment of a public park, public recreational facility or trail, or publicly owned commons of any municipal government or state agency.
