    PCHB Doc 01-160: Proposed Order Granting ACC’s Motion for Summary Judgment Regarding the Absence of a Water Right

    Proposed order from the Washington Pollution Control Hearings Board (PCHB No. 01-160) granting Airport Communities Coalition (ACC) motion for summary judgment on Issue No. 9(a) — whether a water right is required for implementation of the Port of Seattle’s low flow mitigation plan for the Third Runway Project.

    Third runway? Let’s be clear

    This circa-2002 community advocacy document from the Regional Commission on Airport Affairs opposes construction of a third runway at Seattle-Tacoma International Airport, arguing that the Port of Seattle lacked required environmental permits, had already spent over $300 million, and that the project posed serious risks to local wetlands, fish habitat, and watersheds affecting 150,000 south county residents. The document also highlights a controversial proposal to transport arsenic-laden fill material via a conveyor belt through Des Moines Beach Park and Des Moines Creek to the airport construction site. Residents are urged to contact Port commissioners and local city council members to halt the project.

    EXH AR026603: Letter USFWS to James M. Lynch — Monitoring Plan Embankment Fill Seepage, Master Plan Update ESA Consultation (1-3-00-F-1420)

    This December 2001 letter from the U.S. Fish and Wildlife Service's Western Washington office provides detailed comments on a Monitoring Plan for Embankment Fill Seepage related to a Sea-Tac Airport Master Plan Update, reviewed under the Endangered Species Act. The agency requested key revisions, including monitoring both seepage quality and quantity, beginning monitoring when seepage first occurs rather than after embankment completion, and ensuring groundwater wells are considered as a monitoring pathway. The letter also clarified that any exceedances of water quality criteria must be reported promptly, and that the Federal Aviation Administration—not the Port—would be responsible for reinitiating formal consultation.

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.
