Appendix C of the Sea-Tac Sustainable Airport Master Plan covers air quality and greenhouse gas emissions analyses prepared for the Port of Seattle by Landrum & Brown. It includes technical reports on emissions from aircraft, ground support equipment, construction, and other airport sources, as well as a human health risk assessment focused on ultrafine particles. Note that some climate-related sections originally included in the Draft Environmental Assessment were later removed following changes to federal executive orders and a 2025 Supreme Court ruling.

This March 2024 technical report, prepared by Landrum & Brown for the Port of Seattle, assesses air quality and climate impacts associated with near-term construction and operational projects outlined in the Sustainable Airport Master Plan for Seattle-Tacoma International Airport. It analyzes emissions from sources including aircraft, ground support equipment, stationary and mobile sources, auxiliary power units, and construction activities. The report follows NEPA air quality and climate protocols to evaluate potential environmental effects of planned airport improvements.

The Port of Seattle presented an environmental review of near-term construction projects at Seattle-Tacoma International Airport as part of its Sustainable Airport Master Plan. Projects include expanded passenger terminals and gates to handle a projected 56 million annual passengers, additional cargo facilities, airfield safety upgrades to meet FAA standards, taxiway efficiency improvements, and new fuel storage to support Sustainable Aviation Fuel initiatives. The review maps out how these developments will be assessed for their environmental impacts across the airport and surrounding areas.

These images document window condition issues including fogging between glass panes, condensation buildup, mold growth, and deteriorating frames and seals. The photos show evidence of moisture intrusion and seal failure in residential windows, with visible mold, rust stains, and dirt accumulation along window tracks and sills. Such conditions are commonly associated with prolonged exposure to noise-related vibration and humidity in properties near high-traffic areas like airports.

The Port of Seattle's Equity Index tracks community well-being across King County using four categories: Economy, Livability, Accessibility, and Environment. It draws on data from sources such as the U.S. Census Bureau's American Community Survey, EPA EJ Screen, and local agencies to measure indicators like poverty rate, housing cost burden, transit access, and diesel emissions. The index is designed to assess equity and quality-of-life conditions for residents and communities in the region.

Washington State bill E2SSB 5955 creates a grant program, running through July 1, 2029, managed by the Department of Commerce to help large port districts — primarily the Port of Seattle, which operates Sea-Tac Airport — repair or replace faulty noise mitigation equipment installed in nearby homes, and address any structural damage caused by that equipment. Port districts can hire building inspectors or partner with their county to inspect affected properties, and must apply for grant funds when inspections reveal problems. The Joint Legislative Audit and Review Committee will review the program's effectiveness by July 1, 2028.

Washington State Bill E2SSB 5955 creates a grant program, running through July 1, 2029, managed by the Department of Commerce to help port districts — primarily the Port of Seattle, which operates Sea-Tac Airport — repair or replace faulty noise mitigation equipment installed in nearby homes, and to fix any structural damage caused by that equipment. The program is funded through a new 'port district equity fund' drawing from legislative appropriations, local government contributions, and private donations. An independent review by the Joint Legislative Audit and Review Committee is required by July 1, 2028, to assess how many homes have been remediated and how many still need attention.

Sharyn Parker, a retired Noise Officer and Sound Insulation Program Manager at King County International Airport, submitted public comments in February 2024 supporting Washington State bill ESSB 5955, which aims to address longstanding sound insulation repair and replacement issues for homeowners near Sea-Tac Airport. Parker, who managed Boeing Field's Sound Insulation Program from 2009 to 2015, raised concerns about unrealistic timelines, FAA funding eligibility, and the Port of Seattle's early program mismanagement, noting that some homeowners have waited nearly three decades for remediation of defective window installations. She urged legislators to pass the bill and called on the Port to improve contractor oversight, translation services, and public outreach for affected residents.

The Port of Seattle filed this legal reply brief seeking dismissal of a lawsuit brought by five plaintiffs (Codoni, Geer, Cathcart, France, and Chakos) related to Seattle-Tacoma International Airport operations. The Port argues that the plaintiffs' claims are barred by federal preemption under the Civil Aeronautics Act, the Airline Deregulation Act, and the Federal Aviation Act, which collectively give the federal government exclusive authority over aviation and airport operations. The Port also contends that the plaintiffs lack legal standing to bring inverse condemnation claims under the 'subsequent purchaser rule.'
