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

This September 2001 Work Plan Attachment describes the fill suitability testing procedures required for the Port of Seattle's third runway embankment construction at Sea-Tac Airport, outlining how soil and fill materials must meet Washington State and U.S. Fish and Wildlife Service environmental standards. It explains the Synthetic Precipitation Leaching Procedure (SPLP), a laboratory test used to determine whether fill materials could release harmful metals or chemicals into groundwater. Materials failing the screening criteria must be rejected or undergo additional testing before being approved for use in the embankment.

The Airport Communities Coalition (ACC) appealed an amended Clean Water Act Section 401 Certification issued by the Washington Department of Ecology on September 21, 2001, related to construction and expansion work at Seattle-Tacoma International Airport. ACC argued that the amended certification weakened already inadequate water quality protections by limiting its scope, reducing wetland monitoring requirements, loosening fill acceptance standards, and bypassing required public notice and comment procedures. The appeal contended that these changes failed to provide reasonable assurance that the airport project would not violate state and federal water quality standards.

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.

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.

Pollution Control Hearings Board (PCHB) Agreement and Order Re Rescission of 401 Certification, PCHB No. 01-150 and No. 01-133, involving Port Of Seattle and Airport Communities Coalition (ACC) as appellants against Washington State Department of Ecology.
