TagEIS(62)

A 1996 Memorandum of Agreement between the Port of Seattle, FAA, EPA, Washington State Department of Ecology, and the Puget Sound Air Pollution Control Agency established a 24-month air quality monitoring program near Seattle-Tacoma International Airport. The $195,000 program was designed to measure carbon monoxide, nitrogen oxides, and aircraft fuel particle residue in order to establish baseline pollution data and assess the accuracy of earlier 'worst case' air quality models from the airport's Final Environmental Impact Statement. The Port agreed not to proceed with Master Plan expansion projects projected to cause CO standard exceedances until monitoring was complete and, if necessary, appropriate mitigation measures were identified.

Appendix E contains public comments submitted in response to the Final Environmental Impact Statement (FEIS) for the Seattle-Tacoma International Airport Master Plan Update. Commenters include the Highline Water District, the Washington State Department of Ecology, the U.S. Public Health Service, and the Washington State Department of Natural Resources, raising concerns about groundwater contamination, the handling of aircraft de-icing glycols, storm water runoff, and surface mining permit requirements for borrow sites on Port of Seattle property. The agencies generally called for stronger mitigation measures and clearer answers to environmental questions before approving the proposed airport expansion.

This 1996 Final Environmental Impact Statement, prepared jointly by the FAA and the Port of Seattle, evaluates proposed expansion plans at Seattle-Tacoma International Airport through the year 2020, including the construction of a third parallel runway up to 8,500 feet long, a new north terminal, and various landside improvements. The document assesses environmental consequences across 24 categories—including noise, air quality, water quality, and human health—for a range of alternatives, from building a new regional airport to a no-build option. Ultimately, the Port of Seattle selected Alternative 3 as the preferred option, concluding that Sea-Tac was the only feasible site to address the region's growing air transportation needs.

This 1996 Final Environmental Impact Statement, prepared jointly by the FAA and the Port of Seattle, evaluates the environmental effects of proposed expansion and improvement projects at Seattle-Tacoma International Airport, including the construction of a third parallel runway, terminal upgrades, and expanded parking and cargo facilities. The document examines a range of impacts such as wetland disturbance, floodplain encroachment, stream relocation, and noise, water, and air quality effects on surrounding communities. The proposed improvements were planned for completion between 1996 and 2020, with early phases prioritizing the new runway and existing terminal and access enhancements.

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.

Major Supplemental Airport Feasibility Study Summary Report dated March 23, 1995, sponsored by the Puget Sound Regional Council (PSRC), prepared by TAMS Consultants, Inc. in association with Pacific Rim Resources and Parametrix, Inc. The report covers site analysis, noise impact areas (65 Ldn contours), access analysis, instrument approach capability, local airspace evaluation, site constructability, site

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.
