    Comments on the Sea-Tac Airport Master Plan EIS Due August 20, 2026

    A concerned resident living near Sea-Tac Airport submitted formal comments arguing that the airport's Master Plan Environmental Impact Statement (EIS) is deeply flawed, citing inconsistent data, outdated figures, lack of cumulative impact analysis, and poor document organization across its 6,000 pages. The commenter contends that the EIS fragments project reviews to minimize apparent harm, uses selectively chosen baselines to downplay environmental and health impacts on surrounding communities, and fails to address a full build-out scenario. The primary demand is that the EIS be completely redone with transparent assumptions, holistic cumulative impact analysis, up-to-date data, and accessible cross-referenced documentation.

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.
