(AESI, Project No. BV99122C) for Port Of Seattle, dated June 19, 2001, analyzing preferential ground water flow paths relative to the proposed Third Runway at Seattle-Tacoma International Airport (STIA). Evaluates potential contaminant migration from the Aviation Operations and Maintenance Area (AOMA) to the third runway construction

Email chain (AR017302) among Washington State Department of Ecology staff Chung K. Yee, Kevin Fitzpatrick, Craig Thompson, and AAG Joan Marchioro regarding acceptable fill criteria language for the Draft 401 Water Quality Certification for the Seattle-Tacoma International Airport Third Runway project. Key issues include: whether Ecology’s 401 WQ Certification fill criteria should ‘stand alone’ from

Hart Crowser Senior Principal Michael Bailey transmits revised draft plans and cross sections for the Borrow Area 3 Wetland Protection Swale (Job No. 4978-06) to Jim Kelley at Parametrix, June 18, 2001. Documents include Figure 1 (Post-Reclamation Topography and Drainage Facilities), Figure 2 (Typical Cross Sections), Figure 3 (Post-Reclamation Topographical Detail), and Figure 4 (Proposed

These draft meeting notes from a June 14, 2001 technical meeting cover the low flow stream analysis conducted as part of the 401 Permit Decision-Making process for Sea-Tac International Airport's Third Runway project. Attendees from the Department of Ecology, King County, Port of Seattle, and consulting firms identified five additional technical tasks, including verifying groundwater basin calibration parameters for Walker Creek and Des Moines Creek, documenting embankment infiltration rationale, and assessing water availability for proposed low stream flow mitigation measures.

These draft meeting notes from a June 12, 2001 technical meeting cover the Low Flow Analysis conducted as part of the 401 Permit Decision-Making process for Sea-Tac International Airport's Third Runway project. Representatives from the Washington Department of Ecology, King County, the Port of Seattle, and consulting firms discussed the status of hydrological modeling efforts, including HSPF and embankment seepage models, and outlined upcoming deliverables. The group also addressed plans for a mitigation and operational plan to evaluate and offset potential low stream flow impacts caused by the runway project.
