ACC (Airport Communities Coalition) reply memorandum in support of its motion for a stay, filed October 10, 2001, before the Pollution Control Hearings Board (PCHB). Argues that the Amended Certification sets acceptable soil contamination levels too high to protect water quality, citing DOE expert Chung Yee’s 3-phase back-calculating model showing Antimony should be limited to

Second Declaration of C. Linn Gould (Risk Assessor, soil scientist, BA geology, MS soil science) filed on behalf of Port Of Seattle opposing Airport Communities Coalition (ACC) Motion for Stay in PCHB No. 01-133. Gould rebuts ACC’s alleged ‘errors’ in the 401 Certification fill criteria for the Third Runway embankment, addressing MTCA Method A cleanup

Department of Ecology sur-reply brief filed before the Pollution Control Hearings Board (PCHB No. 01-133, PCHB No. 01-160) opposing ACC’s motion for a stay of the Amended 401 Certification for the Third Runway embankment project at Sea-Tac Airport. Ecology argues the Amended 401 Certification does not lessen water quality protections under Condition E (acceptable fill

In a 2001 declaration filed with Washington State's Pollution Control Hearings Board, environmental reviewer Tom Luster argues that the state Department of Ecology's water quality certification for the Sea-Tac Airport expansion was based on speculation rather than the legally required 'reasonable assurance' that water quality standards would be met. Luster contends the certification lacks sufficient evidentiary support and that the approved stormwater and low-flow mitigation plans fall far short of adequately protecting state waters. He warns that accepting this certification approach could set a damaging precedent for future water quality reviews of major projects across Washington State.

Reply declaration of Tom Luster filed October 8, 2001 before the Pollution Control Hearings Board (PCHB) for the State of Washington in Airport Communities Coalition (ACC) v. State of Washington Department of Ecology and Port Of Seattle, case nos. 01-133 and 01-160.

Declaration by Dr. Peter Willing submitted to the Pollution Control Hearings Board (PCHB) for the State of Washington in cases No. 01-133 and No. 01-160, Airport Communities Coalition (ACC) v. State of Washington Department of Ecology and Port Of Seattle. Filed in support of ACC’s reply on motion for stay regarding Section 401 Water Quality

A October 2001 draft memorandum summarizes chemical analysis results from a January 14, 1999 stormwater sampling event at Seattle-Tacoma International Airport (STIA). Water samples were collected from eight receiving stream locations during a storm and tested for metals (copper, lead, and zinc), organic carbon, hardness, and suspended solids. The key finding was that metal concentrations at all sampling sites fell below Washington State hardness-corrected water quality standards (WAC 173-201A-040).

Draft memorandum dated October 5, 2001, from Todd Pollard and Linda Logan to Port Of Seattle project files (project number 556-2625-002), summarizing chemical analysis of STIA receiving stream samples collected January 14, 1999 during a storm event with 86-hour antecedent dry period and 1.18 inches of rainfall. Samples collected from 8 locations including SDS-3, Miller
