TagEnvironmental Impact Statement(140)

This 1996 Final Environmental Impact Statement, prepared by the Port of Seattle and the Federal Aviation Administration, evaluates proposed improvements at Seattle-Tacoma International Airport through the year 2020, including the construction of a third parallel runway, terminal expansions, and parking upgrades. The document assesses a range of environmental impacts such as noise, air and water quality, wetlands, and floodplain encroachment resulting from the planned development. It was prepared in compliance with both the National Environmental Policy Act and Washington State Environmental Policy Act.

This 1996 Final Environmental Impact Statement, prepared jointly by the FAA and the Port of Seattle, evaluates proposed development actions at Seattle-Tacoma International Airport as part of a Master Plan Update. Key proposals include building a third parallel runway up to 8,500 feet long, extending an existing runway, improving passenger terminals, and expanding cargo and support facilities. The document assesses potential environmental impacts such as noise, wetland disruption, air and water quality changes, and floodplain encroachment associated with these planned improvements through the year 2020.

This document is Volume 6 of the Final Environmental Impact Statement for the proposed Master Plan Update at Seattle-Tacoma International Airport, published in February 1996. It covers planned airport improvements from 1996 to 2020, including the construction of a third parallel runway, terminal expansions, and parking upgrades, while assessing impacts on noise, air quality, wetlands, and surrounding communities. The appendix compiles public hearing transcripts and approximately 250 written comments submitted in response to the Draft EIS, addressing key concerns such as aircraft noise, air pollution, and surface transportation impacts.

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.

A 1995 letter from Allan M. Furney to Chester Beattie of the Airport Communities Coalition summarizes a 1974 settlement agreement between King County, the Washington State Highway Commission, and local citizens regarding flooding and drainage problems in the Miller Creek watershed. The settlement requires King County to improve water quality, prevent excess stormwater runoff into Miller Creek, and construct appropriate drainage facilities, while prohibiting full channelization of the creek. The letter raises concerns that proposed SeaTac Airport third-runway expansion plans, as outlined in the Draft EIS, would violate these settlement provisions by significantly increasing impervious surface area and stormwater flows into the Miller Creek drainage basin.

In April 1995, the City of Normandy Park submitted formal comments to the Port of Seattle opposing the proposed Sea-Tac International Airport Hotel, raising concerns that the project would increase traffic congestion and reduce parking availability for local, tax-paying air travelers. The city criticized the Draft Environmental Impact Statement (DEIS) for proposing only 15 new parking spaces to serve a 16-story, 384-room hotel that could generate demand for up to 323 garage spaces at peak periods. The city recommended either no action or a smaller-scale hotel alternative that would fully accommodate its own parking needs without negatively impacting existing airport users.

This March 1995 Draft Environmental Impact Statement, prepared by Kato & Warren, Inc. for the Port of Seattle, evaluates the proposed construction of a 16-story, 384-room hotel on a 77,000-square-foot site at Sea-Tac International Airport, located between the 'D' Concourse and the airport entry drives. The hotel, which would include 10,000 square feet of meeting rooms plus a restaurant and lounge, was to be connected to the terminal and parking garage via pedestrian skybridges on land then occupied by a United Airlines office building. The document was issued for public comment under Washington State's Environmental Policy Act (SEPA), with responses due by April 20, 1995.

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.

Executive Order 12898, signed by President Clinton in February 1994, directs all federal agencies to identify and address disproportionately high and adverse environmental and health impacts on minority and low-income populations. It establishes an Interagency Working Group on Environmental Justice, led by the EPA, to coordinate agency strategies, data collection, and research. Each federal agency was required to develop and finalize an environmental justice strategy within 12 months, ensuring that federal programs do not discriminate based on race, color, or national origin.

The Puget Sound Air Pollution Control Agency (PSAPCA) raised concerns in 1992 about inadequate air quality analysis in the Flight Plan Project's environmental impact statement, citing missing dispersion modeling for both vehicle and aircraft emissions near Sea-Tac Airport. A follow-up 1992 letter addressed the use of ethylene glycol as a de-icing agent at Sea-Tac, concluding it was unlikely to pose a significant air quality risk due to its low vapor pressure. A 1993 internal memo clarified PSAPCA's role in reviewing airport-related environmental impact statements and conducting annual inspections of registered equipment at airports within its jurisdiction.
