    EXH 246: Third Declaration William A. Rozeboom ACC Motion for Stay PCHB No. 01-160

    This 2001 legal declaration by civil engineer William Rozeboom, submitted to Washington's Pollution Control Hearings Board, challenges the Port of Seattle's stormwater and low-flow mitigation plans for the proposed third runway at Sea-Tac Airport. Rozeboom argues that the Port's analysis underestimates low-flow impacts on local streams and that the proposed underground storage vaults—equivalent in volume to more than seven Olympic-size swimming pools—are undersized. The declaration also disputes claims by Port engineer Paul Fendt that the water volumes involved are small and that mitigation can be easily adjusted.

Read This!

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.
