White paper: 2018 FAA Reauthorization noise provisions

The 2018 FAA Reauthorization Act (H.R. 302) includes 14 provisions related to aircraft noise, several of which directly affect airports like Sea-Tac, including requirements for updated noise exposure maps, new community noise concern processes, and health impact studies. Key provisions call on the FAA to study alternative noise metrics to replace the current DNL standard, appoint regional ombudsmen to address noise complaints, and review how NextGen flight path changes have affected surrounding communities. Airports are advised to monitor FAA progress on these studies, as potential changes to the 65 dB DNL threshold and other noise compatibility guidelines could significantly impact community relations and environmental reviews.

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.
