A 2019 University of Washington study found that communities within 10 miles of Seattle-Tacoma International Airport are exposed to ultrafine particle pollution uniquely linked to aircraft emissions, distinct from roadway traffic pollution. These microscopic particles — 700 times thinner than a human hair — are not currently regulated by federal or state air-quality standards, and prior research has associated them with breast cancer, heart disease, prostate cancer, and lung conditions. The policy brief calls on Washington State legislators to fund a follow-up two-year study to investigate the health impacts on nearby communities, which tend to be poorer and more racially diverse than King County as a whole.

The Burien Airport Committee met on December 17, 2019 to discuss ongoing concerns related to Sea-Tac Airport, including the city's legal findings against the FAA, the status of a University of Washington ultrafine particles study, and safety issues raised by Alaska Airlines and Horizon Air. The committee also reviewed progress on the Sea-Tac Stakeholder Advisory Round Table (StART) and a Washington State Department of Commerce study, while planning priorities for 2020. Draft minutes from the November 18, 2019 meeting were included, detailing earlier discussions on noise reduction, environmental impacts, and a potential meeting with the EPA.

The Burien Airport Committee met on May 21, 2019 to discuss several airport-related issues, including updates on the Sea-Tac Airport Master Plan (SAMP) environmental review process, the formation of a coalition of local elected officials to address airport concerns, and research into noise mitigation programs such as the Sound Insulation Program. The committee also reviewed a Federal Way letter to University of Washington professors regarding a study on ultrafine particle pollution from aircraft, and discussed Burien's ongoing participation in the Sea-Tac Airport Roundtable (StART). Draft minutes from the April 16, 2019 meeting reflect earlier discussions on flight curfews, landing fee structures, and airport governance as potential tools for reducing noise impacts on surrounding communities.

In May 2019, Federal Way Mayor Jim Ferrell and the unanimous City Council wrote to University of Washington researchers requesting an expansion of the MOV-UP study measuring ultrafine particle pollution around Seattle-Tacoma International Airport. The letter calls for three key additions: a baseline measurement site unaffected by air traffic, drone-based vertical air sampling before and after aircraft landings at parks, schools, and social justice impact areas, and the design of a permanent 24/7 ultrafine particle monitoring network. The city also offered to support a Port of Seattle grant application to fund the expanded research and pledged to encourage other affected communities to join the effort.

The MOV-UP (Mobile ObserVations of Ultrafine Particles) study, presented at the Highline Forum in January 2019, was commissioned under a Washington State proviso to investigate air quality impacts from Sea-Tac Airport traffic. Researchers from the University of Washington measured ultrafine particle (UFP) concentrations in communities surrounding the airport, aiming to distinguish aircraft-related pollution from other sources. A final study report was due to local governments and the community by December 1, 2019.
