A letter from the City of Burien to WSDOT criticizes the 2017 Washington Aviation System Plan (WASP) for failing to address the health and environmental impacts of growing aircraft noise and air pollution on communities near Seattle-Tacoma International Airport. The letter argues that the plan focuses too narrowly on aviation and economic development while ignoring issues such as hearing loss, poor student performance, sleep disruption, and asthma affecting lower-income and ethnically diverse neighborhoods. The author calls on WSDOT and regional governments to explore alternative airport locations to relieve the disproportionate burden placed on South King County communities.

This document is the FAA's Record of Approval for Seattle-Tacoma International Airport's Noise Compatibility Program, which outlines measures to reduce aircraft noise and manage land use around the airport. It covers both new and updated measures, including voluntary rescheduling of nighttime flights, preferential runway use during nighttime hours, and a Fly Quiet Program to encourage airlines to follow noise abatement procedures. The FAA approved most measures as continuations of previously approved programs dating back to 1985, while disapproving the engine maintenance run-up regulations.

The Burien Airport Committee (BAC) recommends capping flights at Seattle-Tacoma International Airport, citing unacceptable health burdens from aircraft noise and air pollution on surrounding communities. The committee argues that decades of regional planning studies have failed to identify alternatives to concentrating all air traffic growth at Sea-Tac, and that current expansion plans will likely be insufficient beyond 2025. BAC opposes Sea-Tac's SAMP expansion plan and calls on state and regional officials to identify alternative locations for future air passenger and cargo growth.

This presentation examines the consequences of runway configuration changes at Seattle-Tacoma International Airport (Sea-Tac), including louder departure noise for Burien residents, reduced airport capacity, and potential FAA workaround taxi routes. It references Seattle Air Traffic Control Tower standard operating procedures for opening and closing runways, and analyzes the feasibility of simultaneous parallel runway operations under FAA Order JO 7110.65. Key technical challenges identified include the need to relocate the Instrument Landing System, extreme ramp congestion, and the possibility of displacing the Runway 34R threshold by approximately 3,400 feet to achieve parallel threshold alignment.

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.
