This 1995 Federal Aviation Administration report provides detailed technical data supporting the Seattle-Tacoma International Airport Capacity Enhancement Plan Update. Prepared by the FAA Technical Center in Atlantic City, New Jersey, it uses airport capacity and delay simulation analysis to evaluate options for improving airport operations. The information was subject to change as the Design Team's analysis progressed.

The Airport Communities Coalition, representing the cities of Burien, Des Moines, Normandy Park, and Tukwila, Washington, submitted formal scoping comments to the FAA and Port of Seattle regarding the proper scope of an Environmental Impact Statement for a proposed expansion of Seattle-Tacoma International Airport. The comments address key issues including the purpose and need for the project, the role of Puget Sound Regional Council planning, and the requirement for the FAA to independently fulfill its obligations under the National Environmental Policy Act. The document also calls for the EIS to account for connected and cumulative impacts, including planned land-side facility improvements and the Part 150 Noise Mitigation Program.

This August 1994 report, prepared by the Federal Aviation Administration Technical Center in Atlantic City, New Jersey, presents technical data collected as part of the Seattle-Tacoma International Airport Capacity Enhancement Design Team Study. It is the sixth in a series of data packages examining airport capacity and delay simulation at Sea-Tac, with findings subject to revision as the design team's analysis continued. The document serves as an interim reference for planners and researchers studying runway and airspace capacity improvements at the airport.

This document presents the Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments, submitted by the Port of Seattle and approved by the Federal Aviation Administration on May 18, 1994. It outlines updates to existing noise-reduction measures—including sound insulation for homes and public buildings, a transaction assistance program, and an expanded noise monitoring system—as well as newly recommended measures such as community planning forums and operational reviews. The program aims to reduce noncompatible land uses around Sea-Tac Airport and prevent the introduction of new ones.

This document presents the Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments, submitted by the Port of Seattle and approved by the Federal Aviation Administration on May 18, 1994. It outlines a series of noise mitigation measures—including sound insulation programs for homes and public buildings, a transaction assistance program for affected property owners, and an expanded noise monitoring system—aimed at reducing noncompatible land uses around Sea-Tac Airport. Three new measures were also recommended, covering funding for land use planning, a community planners forum, and ongoing operations review and noise exposure map updates.

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.

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.
