Direct testimony of Chung Ki Yee, an Environmental Engineer with Washington’s Department of Ecology Toxics Cleanup Program, submitted before the Pollution Control Hearings Board in a case involving the Airport Communities Coalition and Citizens Against Sea-Tac Expansion versus the Department of Ecology and Port of Seattle. Yee describes his work developing fill criteria for the Port of Seattle’s Third Runway project that are consistent with the Model Toxics Control Act (MTCA). The testimony outlines the technical procedures used to derive soil values for metals and petroleum hydrocarbons using MTCA’s fixed parameter three-phase partitioning model.

Sidebar On/Off

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.
