    Three City Summary of Draft Mediation Issue Proposals

    This document outlines 18 proposed mediation issues submitted by the cities of SeaTac, Burien, and Des Moines in response to the FAA's environmental review of Seattle-Tacoma International Airport's Sustainable Airport Master Plan (SAMP) expansion projects. The proposals seek voluntary commitments from the Port of Seattle and FAA covering a wide range of community concerns, including nighttime flight noise reduction, air quality monitoring, sound insulation for schools and homes, traffic improvements, and a community benefits fund. All proposals are designed to work within existing legal frameworks without requiring the FAA or Port to reopen the environmental assessment.

    Marin Audubon Society v. Federal Aviation Administration: D.C. Circuit Court of Appeals Opinion No. 23-1067

    A federal appeals court reviewed a challenge by conservation groups to an Air Tour Management Plan regulating tourist flights over four national parks near San Francisco, including Golden Gate National Recreation Area and Point Reyes National Seashore. The Federal Aviation Administration and National Park Service had jointly issued the plan under the National Parks Air Tour Management Act of 2000, determining that no full environmental review was required because the plan would cause minimal additional environmental impact. The court considered whether the agencies properly bypassed environmental analysis under the National Environmental Policy Act.

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.
