The Des Moines City Council submitted a series of formal questions challenging the Port of Seattle's environmental review of its airport expansion plan, raising concerns about air quality, noise impacts, and community compensation. Key issues include the Port's heavy investment in Sustainable Aviation Fuel despite its limited near-term viability, the use of outdated federal noise standards, failed home noise-mitigation packages with no funding to repair them, and whether the SEPA review adequately analyzed hazardous air pollutants and peak traffic impacts. The Council also questioned whether the Port should provide direct financial assistance to affected neighboring cities, citing a state solicitor general opinion that such payments may be legally permissible.

This technical memorandum from Harris Miller Miller & Hanson Inc. (HMMH), dated June 5, 2026, presents the results of interior sound insulation testing conducted in April 2026 for 30 homes near Seattle-Tacoma International Airport as part of the SEA Repair and Replacement Program. Acoustical engineers measured how well each room in these homes reduces outside aircraft noise, finding that only 4 of the 30 structures met the FAA's minimum threshold of 45 decibels of interior noise to qualify for sound insulation treatments. An additional 16 homes had at least one room exceeding that threshold, suggesting potential benefit from window and door upgrades, though current FAA policy does not require treatment based on individual room results alone.

This Memorandum of Understanding establishes a cost-sharing agreement between Prince George's County (Maryland), Fairfax County (Virginia), and the City of Alexandria (Virginia) to jointly hire a contractor to study and propose ways to reduce aircraft noise impacts near Ronald Reagan Washington National Airport. Each of the three parties agrees to contribute up to $83,333 toward a total project budget of $250,000, with Alexandria taking the lead on contractor procurement and contract management. The agreement runs for two years with the option to renew for up to two additional one-year terms.

Washington Senate Bill 5898 proposes redirecting a portion of the state's hazardous substance tax on aircraft fuel to fund noise relief for communities near airports. Specifically, 25 percent of those tax proceeds would go into a new "state aircraft noise mitigation account," with the remaining 75 percent continuing to flow to the aeronautics account as before. The Department of Commerce would administer a grant program using these funds to support noise mitigation strategies in communities located within designated aviation impact areas, with the law taking effect July 1, 2027.

Washington State legislation (PSSB 5652) aimed at reducing health and environmental impacts on communities near Sea-Tac Airport, where residents face disproportionate exposure to aviation-related air pollution and noise linked to serious health conditions. The bill establishes a grant program to fix failed noise-mitigation home improvements (known as 'port packages') and fund new mitigation strategies, while directing the University of Washington to conduct ongoing air quality and noise assessments every two years. It also requires the State Auditor to evaluate the Port of Seattle's noise mitigation efforts and directs the Department of Commerce to administer a mitigation grant program using the State Aircraft Noise and Air Quality Mitigation Account.

FAA Eastern Region presentation to NYCAR roundtable on the SKORR6 procedure modification at JFK Airport. The procedure moves the SKORR waypoint from Brooklyn’s Bergen Beach neighborhood to Jamaica Bay to reduce noise exposure over Howard Beach communities by shifting departure flight paths southward over water.

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.

This document is a public comment form from the Airport Noise Remedy Update program, inviting community members to share their feedback on an Open House event and the preliminary program boundaries that were presented for review. The form provided a large blank space for written comments, indicating it was distributed to residents likely affected by airport noise near Sea-Tac Airport. It represents part of an ongoing public engagement process aimed at updating noise remedy policies and determining the geographic scope of the program.

The StART Policy Working Group met on January 5, 2026 to plan advocacy efforts at the state and federal level on behalf of communities neighboring Seattle-Tacoma International Airport. Key topics included organizing a State Day on the Hill in Olympia on February 3, reviewing a proposed study on the airport's socioeconomic and health impacts on surrounding communities, and discussing a recent federal legislative win allowing the FAA to fund secondary noise insulation repair and replacement at airports like SEA. The group also addressed how to handle items lacking full consensus on their State Legislative Agenda, including a contentious airport-related bill expected to be revised in the upcoming session.
