In August 2001, Washington State's Department of Ecology issued a 401 water quality certification to the Port of Seattle for the proposed SeaTac Third Runway, permitting construction of an 8,500-foot parallel runway involving fill of nearly 20 acres of wetlands and development of 700 acres of upland area. The certification imposed strict stormwater management and wetland mitigation conditions, including 201 acres of wetland creation and riparian restoration. The certification was subsequently appealed by the Airport Communities Coalition on August 23, 2001, with a hearing before the Pollution Control Hearings Board scheduled for March 2002.

Transmittal form dated September 6, 2001 from Paul S. Fendt, P.E. of Parametrix (Kirkland, WA) to Ann Kenny at the Washington State Department of Ecology (Bellevue, WA 98008), transmitting wetland hydrology monitoring data for Port Of Seattle, Project Number 556-2912-001 01 03. Includes Lake Reba Area water level data tables for monitoring wells HC00-B151, HC00-B152,

Annual Stormwater Monitoring Report for Seattle-Tacoma International Airport (STIA), prepared by Scott Tobiason, Environmental Management Specialist, Aviation Environmental Programs, Port of Seattle, covering the period July 1, 2000 through June 30, 2001. Report includes NPDES stormwater monitoring data for Sea-Tac Airport storm drainage subbasins, grab and composite sample results for total petroleum hydrocarbons (TPH), fecal

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.

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

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.
