    Aircraft Noise Reduction Act (H.R. 5205)

    H.R. 5205, the Aircraft Noise Reduction Act, is a bill introduced in September 2025 that would allow owners and operators of general aviation airports to work with the FAA to adjust air traffic and training flight patterns in order to reduce aircraft noise in surrounding communities. The bill protects airports from losing federal funding simply for pursuing these noise-reduction measures and requires community input to be considered in the process. It also directs the Secretary of Transportation to update federal regulations to make noise abatement measures more accessible to general aviation airports.

    The Governor’s proposed budget cuts the $1 million in funding that was secured last year through SB 5955 for the Port Equity Fund.

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.
