    Seattle-Tacoma International Airport Sustainable Airport Master Plan near-term projects environmental review scoping report

    The Port of Seattle and the Federal Aviation Administration (FAA) conducted a public scoping process in 2018 to gather input on the environmental impacts of near-term construction projects planned at Seattle-Tacoma International Airport (Sea-Tac) as part of the Sustainable Airport Master Plan (SAMP). The 60-day scoping period, which ran from July 30 to September 28, 2018, invited comments from the public and agencies through meetings, mailings, and an online open house advertised in five languages. This report summarizes the scoping process, public feedback received, and outlines next steps for the full environmental review under both federal (NEPA) and state (SEPA) environmental policy laws.

    Joint Scoping Comments on Sustainable Airport Master Plan Near-Term Projects NEPA EA and SEPA EIS from Cities of Burien, Des Moines, Normandy Park, and Sea-Tac

    In September 2018, the cities of SeaTac, Burien, Normandy Park, and Des Moines jointly wrote to the Port of Seattle urging a broader environmental review of the Sustainable Airport Master Plan (SAMP) for Seattle-Tacoma International Airport. The cities expressed concern that limiting the review to only near-term construction projects would ignore the cumulative noise, air quality, and traffic impacts already burdening their communities. They called on the Port to assess impacts from 2012 onward, include the full long-term SAMP in the environmental analysis, and consider alternative airport sites as part of the review.

    Joint Scoping Comment Letter: Cities of Burien, Des Moines, Normandy Park, and Sea-Tac on SAMP Near-Term Projects NEPA EA and SEPA EIS

    In September 2018, the cities of SeaTac, Burien, Normandy Park, and Des Moines jointly submitted scoping comments on the Port of Seattle's Sustainable Airport Master Plan (SAMP) for Seattle-Tacoma International Airport, raising concerns about the growing impacts of airport expansion on their communities. The cities argued that the environmental review must cover the entire SAMP—not just near-term construction projects—to fully account for cumulative impacts including increased aircraft noise, air emissions, and traffic congestion in nearby residential neighborhoods. They also called for a baseline assessment stretching back to 2012 to capture significant growth that has already occurred without adequate environmental review.

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.
