    Opposition to proposed revisions in FAA grant program, removing Environmental Justice, Climate, and Leaded fuel requirements

    Re https://www.regulations.gov/docket/FAA-2025-0605 Our comment to https://www.regulations.gov/docket/FAA-2025-0605 on the negative impacts new FAA regulations will have on Sea-Tac and KCIA airport communities. Although the new regulations are confined to the AIP grant program, because they are being implemented via Executive Order, it is likely that similar features will be tacked onto all FAA programs concerning leaded

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.
