    Model Toxics Control Act Cleanup Regulation: Process for Cleanup of Hazardous Waste Sites

    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.

    House Bill 1293: Soundproofing programs in aircraft noise-impacted areas

    Washington House Bill 1293 (1995) amended state law governing how port districts can address aircraft noise impacts on nearby properties, expanding soundproofing programs and removing a prior requirement that property owners waive damages and convey easements in exchange for noise mitigation. The bill declared such damage-waiver agreements void as against public policy, meaning residents near airports like Sea-Tac could receive soundproofing benefits without giving up their legal rights. The act was designated an emergency measure, intended to take effect immediately upon passage.

    Substitute House Bill 1915: Aircraft noise abatement–assistance to individual properties

    Washington State's Substitute House Bill 1915, signed into law on April 30, 1993, expanded the tools available to port districts for addressing aircraft noise impacts on nearby properties. The law allows ports to offer affected property owners a range of remedies, including property acquisition, transaction assistance, soundproofing programs, and mortgage insurance. A key update permits individual properties to receive benefits more than once if they experience increased or changed aircraft noise levels that would have warranted a different level of mitigation.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
