Declaration of Edward O’Brien, Washington Department of Ecology Water Quality Program employee since 1979, filed in PCHB No. 01-133 (Airport Communities Coalition v. State of Washington Department of Ecology and Port Of Seattle). O’Brien describes his familiarity with the 1992 Stormwater Management Manual for Puget Sound, the 1999 Draft Manual, and the final September 27,

Declaration of Kelly Whiting, Senior Engineer at King County Department of Natural Resources, filed in Pollution Control Hearings Board case PCHB No. 01-133, Airport Communities Coalition v. State of Washington Department of Ecology and Port Of Seattle. Whiting details his review of the Port of Seattle’s Comprehensive Stormwater Management Plan (SMP) and Low Flow Impact

Port Of Seattle’s memorandum filed October 1, 2001 opposing Airport Communities Coalition (ACC) motion for stay in PCHB Case No. 01-133 before the Pollution Control Hearings Board, State of Washington. Filed by Foster Pepper & Shefelman PLLC. Document AR 008787-008789 addresses wetland mitigation, low flow mitigation plan, stormwater water right permit requirements, fill acceptance criteria,

Declaration of Paul S. Fendt (Parametrix, Inc.) filed in PCHB No. 01-133, Airport Communities Coalition v. Department of Ecology and Port Of Seattle. Fendt, a stormwater engineer with 18+ years experience, addresses stormwater management and low flow mitigation for the Sea-Tac Airport Master Plan Update (MPU). Covers hydrology of Miller Creek watershed (8.1 sq mi,

This document is a legal declaration by Dr. Peter Willing submitted in support of the Airport Communities Coalition's motion for a stay against the Port of Seattle's water quality certification for construction of a third runway at Sea-Tac Airport. Dr. Willing, a water treatment and water quality expert, argues that the Port's plan to augment low summer stream flows using stored stormwater is an unproven concept lacking necessary design details, manufacturer specifications, or documented precedent. He contends that neither the Department of Ecology nor the Pollution Control Hearings Board had sufficient information to evaluate the plan, leaving serious unresolved concerns about potential violations of Washington State water quality standards.

Draft maps prepared by Parametrix, Inc. on September 28, 2001, showing impervious and pervious surface coverage for the Sea-Tac Airport area. Two maps labeled imprv94 and imprv04 depict land surface conditions with dark shading indicating impervious surfaces and light areas indicating pervious surfaces. Documents are part of Administrative Record AR 051192 and AR 051193, likely

This document is a professional resume for Paul S. Fendt, P.E., a geological engineer with over 18 years of stormwater engineering experience. It highlights his role as Parametrix Project Manager supporting the Sea-Tac Airport Master Plan Update, which involved environmental permitting, wetland mitigation, and stormwater management planning for projects including a new third runway. His Sea-Tac work encompassed hydrologic modeling, stormwater treatment facility design, and creek relocation and restoration efforts related to airport redevelopment.

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.
