Port of Seattle Commission presentation (Item 8c supp, October 25, 2022) on the Former United/Continental Tank Farm Site at Sea-Tac Airport, seeking funding authorization and agreement amendment for site closure. The tank farm closed in the 1990s; petroleum contamination was discovered during closure and remediation was initiated in 1995 under a Participation Agreement among United Airlines, Continental Airlines, Olympic Pipeline, and the Port of Seattle under the Model Toxics Control Act (MTCA). Active remediation ceased successfully in 2017; this action addresses final site closure steps.

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.
