    Puget Sound Water Quality Management Plan 2000

    The 2000 Puget Sound Water Quality Management Plan, adopted December 14, 2000, outlines coordinated local, state, tribal, and federal actions to restore and protect the health of Puget Sound in Washington State. The plan introduces new programs addressing aquatic nuisance species and Georgia Basin water coordination, while substantially revising existing stormwater, habitat, and wetlands protection programs. It builds on earlier management plans dating back to 1987 and calls for renewed commitment to funding and policy improvements.

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.
