TagSea-Tac Airport(720)

This document is a catalog of 31 reports and studies published in 1999 related to Sea-Tac Airport expansion and environmental review, including wetland assessments, stormwater monitoring, subsurface conditions reports, and community health studies. Sources range from the Port of Seattle and U.S. Army Corps of Engineers to environmental consultants such as Parametrix and Hart Crowser. The materials primarily concern the proposed third runway project and its impacts on local ecosystems, waterways, and surrounding communities.

This is a library catalog (LBY-2002) listing 16 documents published in 2002 and held in an archive related to Sea-Tac Airport and regional aviation policy. The collection covers topics including airport noise studies, FAA forecasts, wetland mitigation, water quality permits, and legal proceedings involving Section 401 and 404 environmental certifications for the airport. Each entry provides the document title, author or agency, publication date, and the date it was added to the archive.

This document is a fact sheet accompanying an NPDES (National Pollutant Discharge Elimination System) permit issued to the Port of Seattle for Seattle-Tacoma International Airport, governing how the airport manages and discharges treated industrial wastewater and stormwater. It covers discharge locations into Puget Sound, Des Moines Creek, Miller Creek, and the City of SeaTac storm sewer system, and establishes effluent limitations and monitoring requirements. The permit addresses water quality standards, pollution prevention plans, and compliance schedules to protect surrounding waterways from airport-related contaminants.

In September 2002, the Port of Seattle notified nearby residents that it would be removing trees located west and south of Tyee Golf Course, near South 196th Street, at the direction of the Federal Aviation Administration. The trees were identified as hazards to aircraft taking off and landing at Seattle-Tacoma International Airport. Work was scheduled to begin September 16, 2002, and was expected to last up to four weeks.

This August 2002 permit application by the Port of Seattle outlines proposed Master Plan Update improvements at Seattle-Tacoma International Airport, including the construction of a third runway, expanded taxiways, cargo facilities, and terminal upgrades. The documents map both on-site and off-site wetland mitigation areas required to offset environmental impacts, with retaining walls and creek relocations used to minimize effects on wetlands and Miller Creek. The project spans multiple sections of King County, Washington, and includes detailed plans for stormwater detention, runway safety areas, and property acquisition boundaries.

This document is the FAR Part 150 Noise Compatibility Program Study Update for Seattle-Tacoma International Airport (Sea-Tac), approved by the FAA in June 2002. It outlines a series of measures aimed at reducing aircraft noise, including establishing a public oversight committee, exploring noise barriers and ground run-up enclosures, and encouraging the voluntary phase-out of older, louder Stage 2 jet aircraft. The FAA approved some measures outright, while others—such as revised maintenance run-up regulations and the voluntary aircraft phase-out—were disapproved pending submission of additional supporting information.

This catalog lists documents published in 1994 related to Seattle-Tacoma International Airport (Sea-Tac), covering topics such as aircraft noise, environmental impact statements, airport master plan updates, and regional transportation planning. Sources include the Port of Seattle, the FAA, PSRC, and various aviation consultants, with materials ranging from budget reports and feasibility studies to public briefings and technical reports. The catalog serves as an archival index for researchers and policymakers studying airport expansion, noise management, and aviation growth in the Puget Sound region during the mid-1990s.

This is a catalogued index of documents from 2001 related to the proposed Third Runway at Seattle-Tacoma International Airport, covering regulatory filings, public comments, and environmental studies. It includes records from agencies such as the Department of Ecology, the Corps of Engineers, and King County, addressing topics like stormwater management, NPDES permits, groundwater studies, and the impact of the February 2001 Nisqually Earthquake on airport structures. The catalog serves as a reference guide directing researchers to archival notebooks and specific shelf locations where the full documents are stored.

In February 2001, engineering firm GeoSyntec Consultants submitted a technical review letter on behalf of the Airport Communities Coalition, raising serious concerns about the proposed Third Runway expansion at Seattle-Tacoma International Airport. The review identified significant deficiencies in the geotechnical investigation and analysis supporting construction of the embankment fill and West MSE Wall, including insufficient soil strength data and inadequate seismic safety assessments. GeoSyntec warned that the proposed design — which would result in the world's tallest MSE wall built over weak, potentially unstable soils in a seismically active region — could fail under earthquake conditions, threatening both airport operations and nearby natural resources.
