PCHB case No. 01-133, Volume 3 of 3 of Port Of Seattle’s memorandum opposing Airport Communities Coalition (ACC) motion for stay, containing Declaration of Paul S. Fendt. Includes August 3, 2001 letter from King County Department of Natural Resources to Ann Kenny, Senior Permit Specialist, Washington Department of Ecology Northwest Regional Office, Bellevue WA 98008-54552,

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.

Declaration of William A. Rozeboom, PE, senior engineer at Northwest Hydraulic Consultants, filed in PCHB Case No. 01-133 before the Pollution Control Hearings Board for the State of Washington. Filed on behalf of Airport Communities Coalition (ACC) in support of a motion for stay of Section 401 Certification No. 1996-4-02325 and CZMA concurrency statement issued

A September 2001 internal email summarizes a Stipulated Agreement between the Washington State Department of Ecology and the Port of Seattle regarding the third runway construction at Sea-Tac Airport. The agreement clarifies the scope and duration of water quality certification conditions (401 permit), including perpetual wetland mitigation requirements, 15-year wetland monitoring, and rules governing fill material approval and stormwater management. Key changes also address hydrologic monitoring schedules, buffer requirements, and reporting frequency to ensure environmental protections remain in place during and after construction.

This report, prepared by the Port of Seattle in September 2001, presents the findings of annual stormwater monitoring conducted at Seattle-Tacoma International Airport for the period July 1, 2000 through June 30, 2001. It covers water quality sampling results for pollutants including petroleum hydrocarbons, fecal coliforms, suspended solids, metals, and deicing-related contaminants collected from the airport's storm drainage system. The report documents sampling locations, storm events analyzed, and outfall inspections aimed at assessing the airport's environmental impact on surrounding waterways.
