An analysis of FAA and industry data argues that the 'Greener Skies' flight procedure changes at Seattle-Tacoma International Airport provided negligible environmental benefits, saving only about 1.6 million gallons of fuel annually — less than one-third of one percent of the airport's total fuel consumption. Meanwhile, actual fuel use at Sea-Tac grew by hundreds of millions of gallons per year due to increased flight operations, completely overshadowing the claimed savings. The article contends that the program was essentially a public relations campaign that shifted noise burdens onto surrounding neighborhoods without delivering meaningful environmental improvements.

This November 2017 City Council study session presentation outlines a proposed 2018 Interlocal Agreement (ILA) between the City of SeaTac and the Port of Seattle, which operates Seattle-Tacoma International Airport. Because Port properties make up 42% of SeaTac's total land area and the airport creates unique demands on city services, the two governments have used ILAs since 1997 to manage operational and authority issues. The proposed agreement, intended to replace the expiring February 2018 ILA, aims to improve efficiency, reduce costs, and avoid litigation through a mutually beneficial, comprehensive package of terms.

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.

This November 2017 presentation by David Goebel examines how the FAA's NextGen modernization program—specifically the new 'HAWKZ' RNAV flight procedure—has increased aircraft noise over Vashon Island, located west of Seattle-Tacoma International Airport. It explains why so many arriving flights are routed over the island despite SeaTac's runways running north-south, compares the old radar-based approach with the new GPS-guided one, and discusses the real-world altitude impacts residents have experienced. The presentation also covers community response options and what other affected neighborhoods have done to push back against similar NextGen-related noise increases.

This October 2017 presentation outlines the Port of Seattle's draft state legislative priorities for 2018, including support for a study of State Route 518 to address transportation congestion and safety challenges caused by the growth of Seattle-Tacoma International Airport. The agenda also includes workforce development initiatives focused on the maritime, manufacturing, and industrial sectors. The Commission was asked to formally adopt the agenda at the October 24, 2017 meeting.

In October 2017, the Port of Seattle Commission considered its 2018 state legislative priorities, which included workforce development in maritime and industrial sectors, transportation improvements around Sea-Tac Airport, and land use issues affecting port competitiveness. The agenda also addressed support for small and minority-owned businesses, rural economic development, and statewide tourism marketing. While the document covers broad port policy goals, it does not contain specific noise policy provisions related to Sea-Tac Airport operations.
