Local Clean Air Agencies in Washington
ORCAA is one of seven local clean air agencies in Washington. With the passage of the state Clean Air Act, all counties were provided the option of selecting either local authority over the provisions of the act, or letting the state Department of Ecology (Ecology) retain authority.
