    The foundational elements of the Federal Aviation Administration civil aviation noise policy: The noise measurement system, its component noise metrics, and noise thresholds

    The FAA is reviewing its civil aviation noise policy, which is based on decades-old research, to better address how aircraft noise affects communities near airports like Sea-Tac. The review examines noise measurement systems, acceptable noise thresholds, and the impact of aviation noise on residents—including annoyance, sleep disturbance, and health effects. Public and stakeholder input is being sought to help modernize the policy.

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.
