Appeals of Ecology's decisions are made to the Environmental Hearings office, which includes the Pollution Control Hearings Board and the Shoreline Hearings Board, as well as several boards that address appeals of decisions by the state Department of Fish and Wildlife and the Department of Natural Resources.

Administration

Leadership

The Director of the Department of Ecology is appointed by the Governor and subject to confirmation by the State Senate. The current director is Casey Sixkiller, who replaced Laura Watson in 2025.^[7]

Offices

The department has its headquarters office in Lacey, Washington, near the campus of St. Martin's University; four regional offices located in Lacey (Southwest Region), Union Gap (Central Region), Shoreline (Northwest Region) and Spokane (Eastern Region); and field offices in Port Orchard, Manchester, Bellingham, Mount Vernor, Richland,^[8] and Vancouver.^[9]

Programs

The Ecology Youth Corps is a summer jobs program for teenagers in Washington that is managed by the Department of Ecology. Established in 1975, the program is tasked with cleaning litter on state highways and pays hired teenagers a minimum wage.^[10][11]

The Department of Ecology began a vehicle inspection program in 1982, requiring vehicles registered within the state to be inspected for emissions quality. The program ended on December 31, 2019, following a 14-year phase-out approved by the state legislature in 2005 as air quality in Washington cities had improved to above federal standards.^[12][13] Some emissions testing facilities, including two in Seattle, were repurposed as drive-thru COVID-19 testing sites during the 2020 pandemic.^[14]

The department, via its Office of Chehalis Basin (OCB) and the Chehalis River Basin Flood Authority, oversees and funds flood control programs and initiatives, as well as habitat concerns, for the Chehalis River and its watershed.^[15]
