    14 CFR part 150 — Airport noise compatibility planning

    14 CFR Part 150 sets out the federal rules for airport noise compatibility planning, establishing how airports must measure noise, map affected areas, and develop programs to reduce conflicts between aircraft noise and nearby land uses. It defines key terms such as day-night average sound level (DNL), compatible and noncompatible land use, and noise exposure maps, and it outlines the process by which the FAA reviews and approves or disapproves airport noise compatibility programs. Importantly, FAA approval of such a program does not itself commit federal funding or authorize specific actions without further environmental review.

  • Recommended Noise Remedy Boundary Map — Sea-Tac Airport Part 150 Study

    This map, prepared by Landrum & Brown for the Port of Seattle's 14 CFR Part 150 Study at Seattle-Tacoma International Airport, shows the Recommended Noise Remedy Boundary (blue dashed line) alongside the Existing Remedy Boundary (black dashed line) and the Future (2018) NEM/NCP 65 DNL Noise Exposure Contour. The future noise contour covers 7.3 square miles, encompassing an estimated 3,771 housing units, 9,712 residents, and 9 noise-sensitive facilities in communities including Des Moines, Burien, SeaTac, Normandy Park, and Tukwila.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

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.
