Draft geotechnical engineering report prepared by Hart Crowser, Inc. for HNTB regarding the Third Runway Embankment, Phase 5 at Sea-Tac International Airport, SeaTac, Washington (project no. 4978-28, AR 052045). Authored by Josepha D. Celes (Senior Staff Geotechnical Engineer) and Michael Bailey, P.E. (Project Manager). Covers site preparation, subgrade improvement, embankment fill construction, TESC Pond A,

Meeting notes from Erik Stockdale discuss wetland monitoring activities, including monthly groundwater sampling, continuous recorders at drainage channels, and vegetation mapping. Topics covered include hydrology monitoring changes, performance standards for hydrological discharge, and sampling schedules running bi-monthly from November through May. The notes reference coordination among multiple parties regarding soil sampling, data thresholds, and revised performance standards.

Declaration of James L. Morasch, Director of Airports for the Port of Pasco, filed in PCHB case No. 01-133 (Airport Communities Coalition v. Department of Ecology and Port of Seattle). Morasch supports the new all-weather third runway at Seattle-Tacoma International Airport (Sea-Tac). States Sea-Tac is the #1 destination for Tri-Cities Airport passengers, accounting for 47%

Declaration of Alan C. Ralston, Director of Northwest State and Local Government Relations for The Boeing Company, filed in PCHB Case No. 01-133 (Airport Communities Coalition v. Department of Ecology and Port of Seattle) before the Pollution Control Hearings Board for the State of Washington. Ralston declares Boeing’s support for expeditious construction of the Third

Email from Raymond Hellwig (Ecology) to Thomas Fitzsimmons, September 24, 2001, reporting that on September 21, 2001, Ecology reissued the Sea-Tac Third Runway Water Quality Certification per directives from the Pollution Control Hearings Board (PCHB). The reissuance incorporated language from a settlement agreement between Ecology and Port Of Seattle, adjusting certification conditions to clarify how

Declaration of C. Linn Gould (Risk Assessor, soil scientist, MS soil science, BA geology) filed in PCHB No. 01-133, Airport Communities Coalition v. State of Washington Department of Ecology and Port Of Seattle. Gould supports Port Of Seattle’s opposition to ACC’s motion for stay of the Third Runway 401 Certification issued September 21, 2001. Declaration

Dr. John Strand, a fisheries biologist, submitted this declaration to the Washington Pollution Control Hearings Board challenging the state Department of Ecology's water quality certification for Sea-Tac Airport expansion. He argues that stormwater runoff from Seattle-Tacoma International Airport contains copper, lead, and zinc at levels exceeding Washington State Water Quality Criteria, citing the Port of Seattle's own 1995-1996 data showing metals concentrations downstream of airport outfalls far above allowable limits. The declaration was filed in support of the Airport Communities Coalition, representing several cities neighboring the airport, in their motion to stay the certification.

Washington State Department of Ecology Water Quality Certification Order #1996-4-02325 (Amended-1), dated September 21, 2001, issued to Port Of Seattle (Attn: Elizabeth Leavitt) for construction of a third runway and related projects at Seattle-Tacoma International Airport (STIA). Certifies compliance with Clean Water Act Sections 301, 302, 303, 306, and 307; FWPCA Section 401; RCW 90.48.260;

Researchers tested several filtration media, including leaf compost (CSF®) and soybean hulls, for their ability to remove zinc and reduce toxicity from stormwater runoff at Seattle-Tacoma International Airport. The study was prompted by prior water quality monitoring that linked stormwater toxicity to zinc from building materials in certain airport drainage areas. Results from these controlled laboratory tests were used to select the best-performing media for future on-site stormwater treatment trials at the airport.
