Washington State Department of Ecology's Toxic Cleanup Program works to remedy accidental spills of dangerous materials and past business practices that have contaminated land and water throughout the state. These situations range from cleaning up contamination from leaking underground storage tanks to large, complex projects requiring engineered solutions. For a comprehensive list of cleanup sites in Washington State, go to Ecology's site register or view the Toxics Cleanup map.
In 2007, the Department of Ecology identified seven main cleanup project areas in the Puget Sound Initiative. The Port Angeles Harbor has been selected as one of the seven areas to focus cleanup resources. In 2008, a harbor sediment investigation led to the establishment of two separate cleanup areas defined by separate sources of contamination. These two cleanup areas are the Rayonier Mill Cleanup area and the Western Port Angeles Harbor Cleanup area.
