TagThird Runway(1098)

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.

Final draft meeting notes from April 16, 2001 technical meeting on 401 Permit Decision-Making for Sea-Tac Airport Third Runway, prepared by Rachel McCrea of Floyd & Snider Inc. Attendees included John Drabek and Ann Kenny (Dept. of Ecology), Keith Smith (Port of Seattle), Kelly Whiting (King County), Alan Black (HNTB), Paul Fendt and Tom Atkins

This document summarizes correspondence and records related to environmental cleanup efforts at Seattle-Tacoma International Airport, covering the period from 1997 to 2001. It details how Governor Locke conditioned his 1997 certification for the airport's third runway expansion on the Port of Seattle completing a study of decades-worth of hazardous waste contamination in the soil and groundwater at the site. The records also trace the lengthy negotiations between the Port and the Washington State Department of Ecology to establish an Agreed Order under the Model Toxics Control Act, which was ultimately signed in May 1999.

In an April 2001 letter to the Washington State Department of Ecology, Northwest Hydraulic Consultants raised serious concerns about the adequacy of a low streamflow analysis conducted for the proposed third runway expansion at Seattle-Tacoma (Sea-Tac) Airport. The firm argued that Ecology's March 2001 review memo effectively endorsed the study's methods and conclusions without addressing significant technical flaws, including the use of future rather than existing basin conditions and the failure to account for impacts from gravel mining, lagoon lining programs, and embankment seepage. The consultants, representing the Airport Communities Coalition, requested that Ecology revisit its review, consider all submitted technical comments, and require the airport's applicant to formally respond to outstanding concerns before any regulatory certification was granted.

In this April 11, 2001 letter, Washington State Department of Ecology Director Tom Fitzsimmons responds to attorney Kevin Stock regarding concerns raised by the Airport Communities Coalition (ACC) about the Port of Seattle's proposed Third Runway. Ecology agrees to host a technical meeting with ACC experts to examine whether Third Runway infrastructure could create pathways for contaminants from the Airport Operations and Maintenance Area (AOMA) to proposed runway sites, but declines to halt the 401 water quality certification process pending completion of a separate groundwater study. Ecology assures the ACC that it will not approve or deny the Third Runway projects until a 'pathway' analysis addressing contamination concerns is completed.

Revised draft meeting notes from April 9, 2001 technical meeting on 401 Permit Decision-Making for Sea-Tac International Airport Third Runway, prepared by Rachel McCrea of Floyd & Snider Inc.

A 2001 internal email from King County staff puts stormwater storage volumes for the Third Runway project (3RW) into everyday perspective. It compares proposed retention ponds and vaults to familiar landmarks: Pond D would hold the equivalent of over 12 Olympic-size swimming pools, and the largest vault considered (88 acre-feet) would cover a football field with 80 feet of water—roughly an 8-story building. The email also notes that 0.1 cubic feet per second of water flow is equivalent to about five garden hoses running at full pressure.

Final draft meeting notes prepared by Rachel McCrea of Floyd & Snider Inc. from a April 4, 2001 technical meeting on low streamflow impact analysis for the Sea-Tac Airport Third Runway 401 Permit Decision-Making process. Attendees included representatives from Washington Dept. of Ecology (Ann Kenny, Kevin Fitzpatrick, Dave Garland), King County (Kelly Whiting), EarthTech (Rick

This 2001 draft report by Parametrix, Inc. describes a water quality study conducted for the Port of Seattle to assess the feasibility of meeting state water quality standards following construction of a third runway at Seattle-Tacoma International Airport. The study focused on developing a site-specific water-effect ratio (WER) for copper in Miller, Walker, and Des Moines Creeks by conducting toxicity bioassays on stormwater samples collected during storm events. The report summarizes results from initial screening and range-finding phases, with the final site-specific water quality standard still pending completion at the time of publication.

In this March 30, 2001 letter, attorney Kevin L. Stock of Helsell Fetterman writes to Washington State Department of Ecology Director Tom Fitzsimmons on behalf of the Airport Communities Coalition, confirming agreements reached at a March 27 meeting regarding Sea-Tac Airport expansion. The letter asserts that Ecology's 1999 Agreed Order with the Port of Seattle must be fulfilled before a Section 401 water quality certification can legally be issued, and confirms Ecology's commitment to hold a follow-up technical meeting with key staff and legislators present. The ACC argues that strong scientific and legal grounds preclude issuing a defensible 401 certification until the Port completes its obligations under the Agreed Order.
