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.

In an April 2019 letter to the Port of Seattle's Executive Director, Alaska Airlines expressed support for SeaTac airport expansion but raised serious concerns about the Sustainable Airport Master Plan (SAMP), arguing that the proposed 19-gate north terminal is disconnected from the main terminal, more gates than needed, and would leave 80% of travelers underserved. Alaska's independent consultants concluded that only 10 additional gates are necessary to meet projected 2027 passenger demand, and the airline proposed a phased 10-gate alternative as a less costly and less environmentally impactful solution. The letter urged the Port to include Alaska's alternative in the formal NEPA environmental review process to ensure a more legally defensible and balanced approach to airport development.

The Beacon Hill Community Noise Team is a Seattle resident group that documented excessive noise pollution from Sea-Tac and King County airports, as well as road traffic, across 52 neighborhood sites in 2018. Their measurements found that more than half of recorded noise levels exceeded FAA mitigation thresholds, Seattle city ordinances, and EPA public health standards by up to 800%. The group is calling on local, state, and federal officials to take action, citing compounding health and socioeconomic burdens already faced by Beacon Hill's nearly 40,000 residents.

Researchers from the University of Washington studied ultrafine particles (UFPs) — tiny airborne pollutants less than 100 nanometers in diameter — near Seattle-Tacoma International Airport. Their findings highlight that jet aircraft engines produce exceptionally small particles (under 30 nanometers), while diesel vehicles also contribute elevated UFP levels within about 200 meters of major roads. Although UFPs are currently unregulated, a growing body of scientific evidence suggests they pose significant health risks to nearby communities.
