This January 2020 update from the Sea-Tac Stakeholder Advisory Round Table (StART) Noise Working Group covers three main areas: a Ground Noise Study collecting 2019 operations data from airlines, an Aircraft Departure Profiles Analysis showing that the 'distant departure' procedure reduces noise the most for nearby communities, and a Late Night Noise Limitation Program identifying EVA Air, FedEx Express, and China Airlines Cargo as the carriers with the most noise violations in Q4. The study was scheduled to produce a final report with mitigation options by October/November 2020. The update was presented at the Highline Forum on January 22, 2020.

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 SEA Stakeholder Advisory Round Table (StART) 2020 Annual Report, presented by Port of Seattle staff and a consultant, outlines the group's activities and achievements for the year, including work by the Aviation Noise Working Group and the Federal Policy Working Group. The report covers 2020 highlights and accomplishments, facilitator reflections, and tentative priorities for 2021 meetings. StART serves as a community advisory forum focused on addressing aviation noise and related policy concerns at Seattle-Tacoma International Airport.

The Port of Seattle filed a Washington State Leasehold Tax Return for the quarter ending December 31, 2019, reporting a total tax due of $4,804,044.04. The largest portion—$3,195,883.82—was generated from SeaTac leases with taxable rent of approximately $24.9 million, alongside additional revenue from Waterfront, Des Moines, and Burien locations. Payment of the full amount was submitted via ACH Debit on January 31, 2020, one day before the deadline.

This is a Combined Excise Tax Return filed by the Port of Seattle for Seattle-Tacoma International Airport, covering the period ending December 31, 2019, with a due date of January 27, 2020. The document details taxes owed across several categories, including Business & Occupation tax, State Sales and Use tax, and Public Utility tax, totaling $1,503,786.56. Payment was submitted on January 23, 2020 via ACH Debit/E-Check by Port of Seattle staff member Bonnie McArthur.

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.

This December 2019 report by ESA for the Port of Seattle analyzes two standard Noise Abatement Departure Profiles (NADPs) used at Seattle-Tacoma International Airport: the Close-in profile, which reduces noise near the runway end, and the Distant profile, which reduces noise farther along the departure path. The analysis finds that the Distant NADP provides the greatest noise relief to the residential and developed communities surrounding Sea-Tac Airport. The report includes background on departure profiles, noise analysis results, and recommendations for the airport's noise abatement policy.
