In September 2001, representatives from the Port of Seattle and the Washington Attorney General's office exchanged emails negotiating the language of Condition E(1)(b), which governs fill material criteria for an embankment construction project. The proposed language would allow the Port to use a 'drainage layer cover' design and to demonstrate fill suitability through Synthetic Precipitation Leaching Procedure (SPLP) testing as an alternative to standard fill limitations. Under the proposal, SPLP test results would be submitted to the Washington Department of Ecology at least ten business days before any fill placement.

This September 2001 draft settlement agreement between the Washington State Department of Ecology and the Port of Seattle addresses conditions attached to a Clean Water Act §401 Certification for the construction of a third runway at Seattle-Tacoma International Airport. The agreement clarifies and revises specific environmental conditions — including wetland mitigation, stormwater management, and groundwater monitoring requirements — that would remain in effect during and after construction. The Port agreed to file a formal appeal solely to implement the settlement, after which the parties would jointly request the Pollution Control Hearings Board approve the agreed-upon modifications and dismiss the appeal.

This September 2001 draft settlement agreement between the Washington State Department of Ecology and the Port of Seattle addresses the Port's appeal of a Clean Water Act §401 Certification issued for the construction of a third runway at Seattle-Tacoma International Airport. The agreement clarifies and revises several certification conditions related to wetland mitigation, stormwater management, and groundwater monitoring. Both parties agreed to jointly request that the Pollution Control Hearings Board amend the certification accordingly, after which the Port's appeal would be dismissed.

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
