In January 2019, the City of Burien, Washington considered Resolution No. 408, which called for air quality monitoring and health impact assessments of Sea-Tac Airport operations. The resolution highlighted that air traffic had exceeded the airport's projected levels by over 30% and that no air quality monitors existed near the six closest cities to the airport. The Burien Airport Committee recommended adopting the resolution, citing concerns about residents' exposure to pollutants linked to cancer, cardiovascular disease, and other serious health conditions.

The Highline Forum meeting, hosted by the City of Tukwila on November 15, 2017, focused on air quality concerns related to Sea-Tac Airport, featuring a briefing from University of Washington researchers on an ultrafine particles study and a discussion of related federal legislation (HR 4087). The agenda also included updates from the City of Tukwila and the Sea-Tac Stakeholder Advisory Roundtable, presented by Port of Seattle Aviation Managing Director Lance Lyttle. The two-hour session concluded with a discussion of emerging issues and planning for the 2018 Highline Forum schedule.

Researchers from the University of Washington School of Public Health were commissioned by Washington State to study ultrafine particle air pollution near Sea-Tac Airport, the busiest international airport in the state. The study, presented in November 2017, required measuring ultrafine particulate matter within ten miles of the airport along flight paths, distinguishing aircraft emissions from other pollution sources, and comparing affected areas to unaffected ones. Findings and recommendations on whether to proceed with a second phase of research were due to the state legislature by December 1, 2019.

A September 2017 regional air quality briefing presented by the Puget Sound Clean Air Agency to the Highline Forum covers air pollution sources, trends in south King County, and efforts to improve air quality in the region. The presentation also introduces an upcoming University of Washington study on ultrafine particle pollution, which is particularly relevant to communities near high-traffic corridors. The agency's vision emphasizes clean and healthy air for all residents regardless of socioeconomic status or location, covering four counties: King, Pierce, Snohomish, and Kitsap.

This July 2017 presentation by Port of Seattle Sustainability Manager Leslie Stanton outlines air quality initiatives at Seattle-Tacoma International Airport, covering the types and sources of air pollution, the Port's environmental goals, and efforts to reduce emissions. It highlights that while the Port has limited regulatory authority, it is pursuing innovative programs with multiple benefits and tracking emerging science around ultrafine particulates and particulate matter reductions tied to climate strategies. The document serves as an overview of Sea-Tac's approach to managing and improving local air quality amid growing aviation activity.

This document describes a 2015–2018 air quality research project by the Puget Sound Clean Air Agency focused on measuring highway-related air toxics near Interstate 5 in Seattle's Chinatown-International District and Yesler Terrace neighborhoods. The study aimed to assess cancer risks from pollutants such as benzene, formaldehyde, and diesel particulate matter in communities identified as among the most environmentally and economically vulnerable in Washington State. While not directly related to Sea-Tac Airport noise policy, the project represents regional efforts to address transportation-related environmental health impacts on minority and low-income communities in the greater Puget Sound area.
