At a September 2020 Highline Forum meeting, Federal Way resident Bernedine Lund argued that Sea-Tac Airport and the FAA are misleading the public about aircraft emissions by only measuring fuel use during takeoff and landing, while ignoring the far larger greenhouse gas output of full flights. She called on the Port and FAA to be transparent about the total global climate impact of aircraft using Sea-Tac. Her comments emphasized that environmental responsibility must extend beyond airport-specific operations to include the aircraft themselves.

The Burien Airport Committee held a virtual meeting on September 15, 2020, to discuss workplan priorities related to Sea-Tac Airport issues, including community outreach, noise complaints, environmental justice, and preparation for the release of the Supplemental Airport Master Plan (SAMP) Environmental Assessment. The agenda also included a report from Chair Nancy Tosta on a recent FAA meeting, and approval of minutes from the August 18, 2020 meeting. Due to COVID-19 restrictions, the meeting was conducted via Zoom, with public comments accepted by email, text, or online participation.

A community member wrote to a GAO researcher studying NextGen aviation noise impacts near Seattle-Tacoma International Airport, urging that community complaints be paired with responses from the FAA and Port of Seattle to ensure credibility. Key concerns raised include an outdated noise exposure map that has not been updated despite significant growth in air traffic, and the FAA's alleged refusal to answer questions submitted as far back as April 2018. The letter argues that without official rebuttals or supporting documentation, community perceptions risk appearing unsubstantiated and could undermine the integrity of the GAO study.

A bill introduced in the 116th Congress by Representative Smith of Washington would allow airports to receive additional federal funding under the Airport Improvement Program for noise mitigation projects on buildings that have already received such assistance. The bill would permit the Secretary of Transportation to waive the usual restriction on repeat federal funding if increased aircraft noise, deteriorating soundproofing, or damage caused by prior mitigation work justifies further action. Eligible buildings must fall within the DNL 65 noise standard and be certified by a state-licensed building inspector, making this legislation particularly relevant to communities near high-traffic airports like Seattle-Tacoma International.

This U.S. Department of Energy report, prepared by researchers from Pacific Northwest National Laboratory, the National Renewable Energy Laboratory, and the University of Dayton, reviews the technical pathways for producing Sustainable Aviation Fuel (SAF) — alternative fuels designed to reduce the environmental impact of commercial aviation. The report synthesizes findings from multiple expert workshops and evaluates various methods for converting renewable resources into jet fuel. It is intended to inform policymakers, fuel producers, and aviation stakeholders about viable routes toward cleaner air travel.

This document outlines the forty most frequently asked questions about the National Environmental Policy Act (NEPA), covering topics such as how agencies evaluate a range of alternatives, the role of environmental impact statements (EIS), and the use of environmental assessments (EA). It provides plain-language guidance on requirements like the no-action alternative, mitigation measures, public comment periods, and records of decision. While not specific to airport noise, it serves as a foundational reference for understanding the federal environmental review process that governs major infrastructure projects such as those at Sea-Tac Airport.

This 2020 report examines how noise from Seattle-Tacoma International Airport has changed between 1997 and 2019, focusing on the impact of aircraft takeoffs, landings, and overflights on nearby communities. It explains key noise measurement concepts—including decibels, Sound Exposure Level (SEL), and the Day-Night Average Sound Level (DNL)—and notes that while DNL is the federal regulatory standard used by the FAA, individual SEL events are often what residents find most disruptive. The report highlights a growing tension between how federal agencies measure and regulate aircraft noise and the real-world experience of people living under flight paths.
