    Notice of funding opportunity for Environmental Mitigation Pilot Program

    The FAA announced a Notice of Funding Opportunity for an Airport Environmental Mitigation Pilot Program, authorized under Section 190 of the FAA Reauthorization Act of 2018, which provides grants of up to $2.5 million per project to help public-use airports measurably reduce aviation impacts on noise, air quality, or water quality within five miles of the airport. Up to six projects may be funded, with costs split 50/50 between federal and airport matching funds, and projects must be carried out by an eligible consortium of businesses, educational or research organizations, government entities, or federal laboratories. Pre-applications were due by July 9, 2021, and priority was given to projects achieving the greatest reductions in aircraft noise, emissions, or water quality impacts.

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.
