Final Decision on Noise Issues – Expert Arbitration Panel’s Review of Sea-Tac International Airport

In March 1996, an Expert Arbitration Panel reviewed whether the Port of Seattle had met noise reduction requirements set by the Puget Sound Regional Council as a condition for approving a third runway at Sea-Tac International Airport. A majority of the Panel concluded that, despite the Port's extensive noise abatement programs, it had not demonstrated a sufficient reduction in real, on-the-ground noise impacts to satisfy Resolution A-93-03. This decision left the noise condition as the sole remaining hurdle for authorizing the third runway's construction.

Notes

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.
