Letter dated December 27, 2001 from Keith R. Smith, Water Resources Manager at Port Of Seattle Seattle-Tacoma International Airport, to Ms. Ann Kenny at Washington State Department of Ecology (Bellevue, WA 98088-5452), transmitting construction stormwater monitoring reports for September, October, and November 2001 under Section K.6 of Water Quality Certification No. 1996-4-02325 (Amended-1) and NPDES

Declaration by Brett Fish, President of Citizens Against Sea-Tac Expansion (CASE), filed in PCHB No. 01-160 (Airport Communities Coalition v. Washington State Department of Ecology and Port Of Seattle). Fish declares CASE’s interest in intervening in the ACC’s appeal of Ecology’s 401 Certification for the proposed third runway and master plan update at Sea-Tac Airport.

Memorandum filed by Citizens Against Sea-Tac Expansion (CASE) supporting its motion to intervene in PCHB No. 01-160, Airport Communities Coalition v. Washington State Department of Ecology and Port Of Seattle. CASE seeks intervenor status under Civil Rule 24 and WAC 371-08-420(1) in the appeal of Amended Clean Water Act 401 Certification No. 1996-4-02325 (Amended-1) issued

A study at Seattle-Tacoma International Airport found that galvanized metal roofing on cargo buildings was the primary source of elevated zinc levels in the airport's stormwater runoff, which drains into salmon-bearing streams including Miller Creek and Des Moines Creek. Researchers used whole effluent toxicity (WET) testing and source-tracing methods to identify the problem, focusing on one outfall (SDN1) that consistently showed higher zinc concentrations and toxic effects on aquatic organisms. The findings prompted the Port of Seattle to investigate remediation options as part of its stormwater pollution prevention program under its NPDES permit.

Declaration of Greg Wingard (Executive Director, Waste Action Project) filed October 8, 2001, in Environmental Pollution Control Hearings Board cases No. 01-133 and No. 01-160, Airport Communities Coalition v. State of Washington Department of Ecology and Port Of Seattle. Supports ACC’s motion for stay of Section 401 Certification No. 1996-4-02325 (Amended-1) and CZMA concurrency statement

Declaration of Kevin Fitzpatrick, Section Manager at Washington Department of Ecology (Ecology) Northwest Regional Office Water Quality Program, filed in PCHB No. 01-133, Airport Communities Coalition (ACC) v. State of Washington Department of Ecology and Port Of Seattle. Fitzpatrick addresses ACC’s contentions that Port Of Seattle stormwater discharges from SeaTac International Airport (STIA) violate state

Conference paper submitted September 21, 2001 to Water Environment Federation for Watershed 2002 conference, authored on behalf of the Port Of Seattle regarding Sea-Tac Airport stormwater best management practice (BMP) screening. Tests filtration media — deciduous leaf compost (CSF®), soybean hulls (SBH), extra fine deciduous leaf compost (XFCSF), commercial inorganic polyamine sponge, and zeolite/perlite (ZP)

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.

This legal declaration, filed before Washington State's Pollution Control Hearings Board, was submitted by environmental consultant Greg Wingard in support of the Airport Communities Coalition's motion to stay a Section 401 water quality certification related to Sea-Tac International Airport. Wingard details his extensive review of the airport's NPDES stormwater permits since 1994 and describes his attempts to obtain construction outfall monitoring records from the Department of Ecology through Public Disclosure Act requests. His investigation found that Ecology lacked key monitoring data it had previously claimed to possess, directing him instead to contact the Port of Seattle directly for the records.

Annual Stormwater Monitoring Report prepared by Port Of Seattle pursuant to Special Condition S2.E of the NPDES permit for Seattle-Tacoma International Airport (STIA), covering July 1, 2000 through June 30, 2001. Report covers 14 outfalls per permit condition S2.B; 61 grab and 59 composite samples from 22 storm events; 7-year cumulative totals exceed 400 samples
