Parametrix, Inc. report prepared for Port Of Seattle assessing the existing (1994) and future (2006) hydrologic divide of Miller Creek, Walker Creek, and Des Moines Creek following Master Plan Update (MPU) construction at Seattle-Tacoma International Airport (STIA). Analyzes compliance with Governor’s Certification requirement that the third runway project will not cause changes in the location

Email chain (AR018498–AR018499) dated July 19, 2001, from Erik Stockdale (likely Washington State Department of Ecology) to Joan Marchioro (ATG) and Andy McMillan, forwarding a message from Jim Kelley of Parametrix, Inc. The judge ruled in favor of Port Of Seattle in the Parcel 92 condemnation case, finding that prior converted croplands were wetlands under

A water resources consultant raised concerns in a July 2001 letter to the U.S. Army Corps of Engineers and Washington State Department of Ecology about the Port of Seattle's stormwater management plans for Sea-Tac Airport expansion. The letter challenged the effectiveness of proposed biofiltration swales, noting they can actually increase bacterial levels rather than reduce them, and warned that releasing stored stormwater from detention vaults into nearby Class AA streams could discharge pollutant-laden, oxygen-depleted water into already stressed waterways. The consultant concluded that the Port's plans fell short of providing reasonable assurance that water quality standards would be met.

A July 18, 2001 letter from Helsell Fetterman law firm to the Washington State Department of Ecology complains that the Airport Communities Coalition (ACC), representing over 150,000 residents near Sea-Tac Airport, had not received any Public Disclosure Act documents from Ecology's Northwest Regional Office for over a month during the critical review of the Sea-Tac Third Runway project. The letter specifically highlights that a key contaminants pathways analysis dated June 19, 2001 was withheld for weeks, preventing ACC's independent scientific experts from providing timely comments on potential environmental and contamination risks. The attorneys urge Ecology to halt issuing a Section 401 water quality certification decision until the document disclosure cutoff is reversed and ACC's scientists have had a fair opportunity to review and respond to the Port's latest submissions.

Memo dated July 18, 2001 from Tom Fitzsimmons, Director, Washington State Department of Ecology, to Governor Gary Locke regarding the status of the 401 Water Quality Certification decision for the Port Of Seattle proposed Third Runway and associated projects. Ecology is awaiting final technical information from Port consultants on stream low-flow mitigation requirements, expected by

In a July 18, 2001 memo to Governor Gary Locke, Washington State Department of Ecology Director Tom Fitzsimmons provided an update on the permitting process for the Port of Seattle's proposed Third Runway at Sea-Tac Airport. The department was awaiting final technical data from the Port on stream low-flow mitigation, expected by July 23, 2001, before issuing a 401 Water Quality Certification decision. Provided the information was satisfactory, Ecology planned to render a final decision on the runway project during the week of August 6, 2001.

Handwritten note from Yvonne to ‘Azura’ transmitting notes from Gordon regarding the Third Runway, noting he does not think they are deliberative.

Final meeting notes from July 16, 2001 for the 401 Permit Decision-Making process for Sea-Tac International Airport Third Runway, covering low flow analysis for Miller Creek and Walker Creek. Attendees included Ann Kenny (Dept. of Ecology), Kelly Whiting (King County), Keith Smith (Port of Seattle), Paul Fendt and Robert Farid (Parametrix), Rick Schaefer (EarthTech), and

Final meeting notes prepared by Kate Snider of Floyd & Snider Inc. for the 401 Permit Decision-Making process for the Sea-Tac International Airport Third Runway project, dated July 16, 2001. Attendees included representatives from Washington State Department of Ecology (Ann Kenny), King County (Kelly Whiting), Port of Seattle (Keith Smith), Parametrix, EarthTech, and Aquaterra. Document

In a July 13, 2001 email, Ann Kenny of Washington State Department of Ecology urged the Port of Seattle to continue researching the water quantities contributed to base stream flows by septic tank systems slated for removal in the airport acquisition area. She noted that while eliminating septic tanks helps reduce fecal coliform contamination, it also removes water that recharges base flows — a water quality concern regulated under RCW 90.48. Kenny suggested the Port work to verify the accuracy of a 66,000-gallons-per-day estimate from its December 2000 Low Stream Flow Analysis by cross-referencing sewer authority and water supplier records.
