    Letter of understanding regarding the environmental review of the Sustainable Airport Master Plan

    In this September 2015 letter, the Port of Seattle and the City of SeaTac reached a mutual agreement regarding the environmental review of Sea-Tac Airport's Sustainable Airport Master Plan (SAMP). The Port committed to conducting a full environmental analysis of all anticipated airport growth — including international passenger traffic — as part of the SAMP review process, addressing the City's concerns about transportation and other impacts. In exchange, the City agreed not to file an appeal on the Final Declaration of Non-Significance issued for the International Arrivals Facility project.

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.
