    Airport noise mitigation program implementation guidelines

    This document outlines how airport noise impact programs can be approved and funded under the Airport Improvement Program (AIP). Once a detailed study confirms substantial community noise impact and a reasonable solution is proposed, costs become eligible for approval. Specific guidelines must then be developed covering property acquisition or sound insulation options, including owner agreements, appraisals, market exposure, noise insulation standards, and relocation proposals.

    Interim answers to November 9, 1983 letter regarding airport noise remedy program

    This letter from Edward G. Tatum, Manager of the FAA Airports Division, provides interim answers to the Port of Seattle's questions about federal funding and guidelines for airport noise remedy programs near Sea-Tac Airport. It outlines key details such as 80% federal cost coverage under the Airport Safety and Noise Abatement Act, eligibility criteria for sound insulation and property purchase assistance programs, and interior sound level standards based on EPA recommendations. The letter acknowledges that the FAA and Port of Seattle are breaking new ground together in developing policies that could serve as a nationwide model for noise abatement programs.

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.
