Declaration by Dr. John Strand, Principal Biologist for Columbia Biological Assessments, filed in PCHB cases No. 01-133 and No. 01-160, in support of ACC’s motion to stay Section 401 Certification No. 1996-4-02325 (Amended-1) issued by Washington Department of Ecology for USACOE Public Notice 1996-4-02325 regarding Seattle-Tacoma International Airport (STIA). Strand addresses metals exceedances — copper,

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

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 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.

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.

This 2001 Natural Resource Mitigation Plan document for Seattle-Tacoma International Airport outlines proposed environmental mitigation actions associated with construction of a new third runway and related facilities. It details a sequenced approach to avoiding, minimizing, and compensating for impacts to wetlands, Miller Creek, Des Moines Creek, and other natural resources. Key measures include constructing retaining walls to protect wetlands, restoring the Vacca Farm floodplain, establishing forested stream buffers, and providing a $300,000 trust fund for fisheries habitat enhancement.

This technical memo evaluates whether lead and zinc levels found in cutthroat trout from Miller Creek pose a risk, arguing that standard tissue screening concentrations are not appropriate for trout. Using fish-specific toxicity data and bioconcentration factors, the authors derive alternative thresholds and conclude that measured metal levels in the trout fall well below harmful concentrations. The document recommends using species-specific methods rather than generic screening values when assessing metal risks to fish.

Response to Comment #16 by David DeForest to Linda Logan (September 2001) critiquing Shephard (1999) tissue screening concentrations (TSCs) for lead (0.32 mg/kg dw) and zinc (100 mg/kg dw) as applied to cutthroat trout from Miller Creek. Argues Shephard TSCs derived from EPA water quality criteria and bioconcentration factors (BCFs) are not appropriate for cutthroat

Document AR028003 covers the Port’s proposals to construct an 8,500-foot parallel third runway, two Runway Safety

Letter dated August 10, 2001, from James M. Lynch of Stoel Rives LLP, attorney for the Port Of Seattle, to Ken Berg, Manager of the U.S. Fish and Wildlife Service (FWS) Western Washington Office, transmitting a draft Embankment Seepage Monitoring Plan (MP) for the proposed Sea-Tac Airport Third Runway embankment fill.
