Seattle-Tacoma International Airport operates one of the nation's most comprehensive airport noise management programs, divided into Noise Abatement measures — such as restricting noisy Stage 2 jets at night, controlling ground engine use, and routing flights over fewer homes — and Noise Remedy programs that help affected residents through home sound insulation, sales assistance, and a relocation program that has already moved over 3,900 people. The Port of Seattle also maintains a 24-hour noise complaint hotline and an 11-station monitoring system to track and reduce noise levels around the airport. Residents can contact the Port directly for information, to report concerns, or to learn about eligibility for free home insulation.

This March 1994 Final Environmental Impact Statement, prepared jointly by the Federal Aviation Administration's Seattle Airports District Office and the Port of Seattle, evaluates the proposed South Aviation Support Area at Seattle-Tacoma International Airport. The document assesses the potential environmental effects of developing aviation support facilities in the southern portion of the airport, covering impacts such as noise, land use, and related concerns. It was produced as part of the federally required environmental review process before any major airport infrastructure decisions could be approved.

The Port of Seattle operates a noise information line (433-5393 or 1-800-826-1147) that allows area residents to report aircraft noise complaints, ask questions about Sea-Tac's noise abatement programs, and request evaluations of specific noise events. Calls are documented in a database, and summaries are shared with FAA air traffic officials, Port Commissioners, and the public to help monitor and improve noise programs. However, the Port cannot take immediate action — such as modifying flight tracks — based solely on phone complaints.

This archival box (Box No. 01286, Historical ID 1318) contains records from the Puget Sound Regional Council's Administration office spanning 1994–1996, related to airport litigation and noise policy at Sea-Tac Airport. The materials include Expert Arbitration Panel audio tapes, meeting minutes, procedural and final orders, and MSA Coordinating Committee correspondence and agendas covering topics such as Phase II noise issues, demand/system management, and compliance reporting. The records are stored at the Washington State Archives and were prepared by Angie Daniels.

A 1993 letter from the Port of Seattle to a Des Moines resident explains that airline deicing at Sea-Tac Airport uses only FAA-approved ethylene or propylene glycol, and that wastewater from deicing drains to the airport's treatment system before being discharged to Puget Sound — not to Miller or Des Moines Creeks. The Port acknowledged its treatment plant was not designed to handle glycols and was evaluating upgrades. A follow-up 1996 letter challenges a contradictory statement in the airport's Final Environmental Impact Statement, which claimed most deicing fluids were contained and treated by the Port's Industrial Wastewater System.

This quarterly Sea-Tac Noise Abatement Report from the Port of Seattle (Q4 1992) tracks progress in reducing airport noise, highlighting that 71% of jet flights were operated by quieter Stage 3 aircraft, up from 63.4% the previous quarter. All airlines stayed within their allocated noise budgets, and new nighttime restrictions effective October 1, 1992 limited louder Stage 2 jets between midnight and 6:00 a.m. The report also outlines noise abatement flight procedures designed to route departing and arriving aircraft over industrial areas and water to minimize noise impacts on surrounding communities.

This April 1993 confidential legal report, prepared by law firm Cutler & Stanfield for the Airport Communities Coalition, examines the legal issues surrounding the proposed expansion of Seattle-Tacoma International Airport, including the construction of a third runway. It reviews the powers and responsibilities of key governmental entities — including the FAA, the Port of Seattle, the Puget Sound Regional Council, and surrounding cities — in relation to airport planning, noise abatement, and environmental impacts. The report also assesses geographic and environmental conditions in the SEA area, covering noise-sensitive locations, wetlands, air quality, and other factors relevant to community opposition to the expansion.
