This Washington State Department of Ecology fact sheet explains how the Model Toxics Control Act (Initiative 97, 1989) governs the cleanup of hazardous waste sites in Washington, outlining who is liable, how sites are identified, and the options available for conducting cleanups. Potentially liable parties — including past and present owners, operators, and those who transported or disposed of hazardous substances — may clean up sites independently or work cooperatively with Ecology through formal agreements such as consent decrees. Note: this document concerns hazardous waste site cleanup regulation and does not contain information related to Sea-Tac Airport noise policy.
