This 1996 Final Environmental Impact Statement (EIS), prepared by the FAA and Port of Seattle, evaluates the environmental effects of proposed expansion plans at Seattle-Tacoma International Airport, including construction of a third parallel runway, terminal upgrades, and parking improvements planned through 2020. The document addresses key community concerns such as aircraft noise, air quality, surface traffic, and impacts on wetlands and floodplains. It includes transcripts and written comments from two public hearings held in June 1995, attended by community members and agencies who raised significant concerns about noise, health, and environmental impacts.

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.

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 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.

In a November 1992 letter to the FAA's Northwest Mountain Region manager, the President of the Regional Commission on Airport Affairs urges the federal government to defer funding and detailed planning for a proposed third runway at Seattle-Tacoma International Airport (Sea-Tac). The letter argues that the Puget Sound Regional Council's ongoing regional airport system planning process must be allowed to fully evaluate all alternatives before any single project receives federal financial commitment. The author warns that proceeding prematurely with site-specific plans and an Environmental Impact Statement risks wasting federal money if the regional plan ultimately selects an alternative other than a third runway at Sea-Tac.

A 1992 water quality study of Des Moines Creek, prepared by Parametrix, Inc. for the FAA and Port of Seattle, assessed the health of the creek during storm runoff events. The creek, which originates near Sea-Tac International Airport and flows to Puget Sound, had its aquatic ecosystem severely damaged by jet fuel spills in 1985 and 1986. The study sampled seven locations along the creek and three tributaries to identify water quality problems and determine whether stormwater pollution from airport operations was causing toxic conditions.
