Local communities surrounding Seattle-Tacoma International Airport are demanding accountability from the Port of Seattle (POS) regarding its compliance with FAA Part 150 noise mitigation measures, some dating back to 1985. The document raises detailed questions about ten specific program elements — including voluntary flight rescheduling, engine run-up restrictions, noise abatement corridors, the Fly Quiet Program, and home sound insulation — asking for data on how consistently and effectively each measure has actually been implemented. Critics argue that despite decades of commitments, key noise reduction tools such as a Ground Run-Up Enclosure have been quietly dropped, while growing air traffic continues to harm residential neighborhoods and environmentally vulnerable populations.

Handwritten notes reviewing an FAA document on airport grant assurances, referencing noise mitigation policy and Kandahar Corridor Syndrome (KCS). The notes criticize the postponement of noise mitigation efforts in favor of the SAMP (Sustainable Airport Master Plan), quoting language suggesting 'little or no downside for the clients' and expressing concern that passengers and airlines are being prioritized over local communities. A URL referencing FAA airport grant assurances (airport-sponsor-assurances-aip(1).pdf) is also included.

The Quiet Skies Coalition challenges the FAA's Categorical Exclusion (CATEX) for new turboprop flight routes over Burien, Washington, arguing that the FAA's own noise analyses show significant increases in noise levels that exceed the agency's 1.5 dB DNL significance threshold — contradicting the FAA's claim of no environmental impact. The coalition contends that the FAA's reliance on an outdated 2013-2018 Sea-Tac Part 150 noise study, which failed to account for a 51% increase in airport operations, led to inaccurate noise assessments and improper use of a categorical exclusion. Community members and the City of Burien are urged to join legal and political efforts to challenge the FAA and Port of Seattle's authority over flight path decisions affecting residents from Shoreline to Federal Way.

A legal and regulatory analysis arguing that the FAA must conduct a broader cumulative environmental impact review of Seattle-Tacoma International Airport expansion, following a 9th Circuit Court ruling that remanded the 'Burien Turn' flight path back to the FAA. The document contends that multiple airport expansion projects—including the addition of 14 new gates and the extension of Highway 509—were each approved individually under categorical exclusions (CATEXs) without properly accounting for their combined effects on noise, air quality, and environmental justice communities. The author argues that under NEPA regulations, the FAA is required to analyze these past, present, and future actions together to determine whether their collective impact is significant.

This document presents a point-by-point rebuttal to an FAA 'Limited Update' regarding a new flight departure procedure at Seattle-Tacoma International Airport, arguing that the FAA has failed to conduct required safety risk analyses, properly assess cumulative noise and air quality impacts on environmental justice communities, and comply with court-ordered environmental review under NEPA. The authors contend that the FAA is understating the scope and timeline of the Sea-Tac Airport Master Plan (SAMP) expansion while dismissing significant health, noise, and emissions impacts on nearby residents. The critique calls out procedural shortcuts, incomplete public comment responses, and what it characterizes as predetermined conclusions designed to avoid full environmental scrutiny.

This legislative summary outlines a proposed bill to protect communities near busy flight routes from aviation noise and pollution. It establishes a process for the FAA to designate 'aviation-impacted communities' located within one mile of low-altitude commercial or cargo flight paths, create local community boards to engage with the FAA and airport operators, and develop action plans and mitigation funding for affected residents. Key provisions include grants for sound insulation and noise barriers, eligibility for neighborhoods within a 55 DNL contour, and requirements for the FAA to respond to community concerns within set deadlines.

This document provides an overview of the Aviation Impacted Communities Act, which establishes a formal process for communities affected by airport noise and flight paths. The process begins with the FAA notifying eligible communities of their 'designated community' status, then proceeds through board formation, meetings, studies, action plans, and ultimately grants for mitigation funds. A community qualifies as 'aviation impacted' if it is located no more than one mile from any commercial or cargo jet route at 3,000 feet or less above ground level.

This presentation, prepared for the City of Burien Airport Committee, examines the governance structure of Washington State's special purpose port districts and the FAA's preeminent authority over airport operations. It explains that port districts, enabled by state law since 1911 and governed by directly elected commissioners, hold broad powers including management of airports, while federal FAA regulations take precedence over local planning decisions. The document also touches on noise control considerations relevant to communities near Sea-Tac Airport, referencing state and federal regulatory frameworks.

The FAA Reauthorization Act of 2024 (H.R. 3935) is a comprehensive Senate bill proposing to reauthorize and reform the Federal Aviation Administration and civil aviation programs. It covers a wide range of topics including airport planning and noise compatibility programs, FAA organizational oversight, and numerous aviation safety improvements. Of particular relevance to airport communities, the bill includes provisions addressing noise compatibility planning, airspace modernization, and safety standards that may affect operations at airports like Sea-Tac.
