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.
