Email dated August 10, 2000 from Kate Rhoads to Kelly Whiting transmitting a Word document (POS-Cu.doc) containing technical comments on copper (Cu) levels in stormwater runoff from Seattle-Tacoma International Airport (STIA) runways. AR017903-017904. Comments address total recoverable (TR) copper median concentration of 37 ug/l versus the dissolved fraction surface water acute toxicity standard of 4

Hart Crowser draft report prepared for Port of Seattle, August 9, 2000 (J-4978-13), evaluating perched groundwater zone interception and potential wetland hydrology impacts from Borrow Area 3 excavation for the Sea-Tac Third Runway project. Addresses Pacific Groundwater Group (PGG, 2000) concerns commissioned by Washington State Department of Ecology regarding impacts to Wetland 29. Includes ModFlow

Society of Wetland Scientists (SWS) position paper dated August 6, 2000 defining ‘wetland restoration’ as actions taken in a converted or degraded natural wetland that reestablish ecological processes, functions, and biotic/abiotic linkages leading to a persistent, resilient system integrated within its landscape. The paper covers five key scientific considerations: reinstatement of driving ecological processes (hydrology,

The Port of Seattle submitted a Joint Aquatic Resources Permit Application (JARPA) in August 2000 for the Miller Creek Project, part of Master Plan Update Improvements at Seattle-Tacoma International Airport. The application, prepared by Parametrix, Inc., seeks permits related to work affecting Miller Creek, Walker Creek, and associated wetlands in the City of SeaTac. The project required approvals from multiple agencies, including the Washington Department of Fish and Wildlife for a Hydraulic Projects Approval (HPA).

Letter dated August 1, 2000 from Associated Earth Sciences, Inc. (AESI), Project No. BV97016D, to Mr. John Wietfeld and Mr. Roger Nye of Washington State Department of Ecology Northwest Regional Office, on behalf of Port Of Seattle. Transmits quarterly ground water level measurements for Q1–Q4 from select wells completed in the C1 (Qva) advance outwash

Wildlife Hazard Management Plan (WHMP) for Seattle-Tacoma International Airport (SEA), developed by Port Of Seattle in cooperation with USDA Animal and Plant Health Inspection Service (APHIS) Wildlife Services, Olympia, WA, August 2000, AR 045494. Covers habitat management (grass, wetlands, water, vegetation, structure), wildlife control procedures (bird and mammal control, wildlife patrol), laws and regulations (Washington

In a July 31, 2000 letter to the U.S. Army Corps of Engineers and Washington State Department of Ecology, Northwest Hydraulic Consultants — representing the Airport Communities Coalition — raised concerns about unresolved technical problems with the Stormwater Management Plan (SMP) for Seattle-Tacoma International Airport's proposed third runway. Independent reviews had identified serious flaws in hydrologic modeling that could result in undersized stormwater facilities failing to meet flow control requirements. The consultants urged regulators to publicly disclose ongoing SMP discussions and allow meaningful time for further review before approving the project.

In a July 31, 2000 letter to the U.S. Army Corps of Engineers and Washington State Department of Ecology, Northwest Hydraulic Consultants raised concerns about unresolved technical problems with the Stormwater Management Plan (SMP) for the proposed third runway at Seattle-Tacoma International Airport. Independent reviews had found serious flaws in the hydrologic modeling that could result in undersized facilities failing to meet flow control requirements. The firm requested full public disclosure of ongoing SMP discussions and a meaningful comment period before any regulatory approval of the runway project.

Email chain dated July 30, 2000 from Kelly R. Whiting, PE, King County Department of Natural Resources, Water and Land Resource Division, Drainage Services Section, to David Masters and Tom Luster (WDOE), forwarding water quality specialist Kate Rhoads’ notes on copper (Cu) levels in Seattle-Tacoma International Airport (STIA) runway stormwater runoff. Whiting discusses KCSWDM (King

Email from Kate Rhoads to Kelly Whiting dated July 28, 2000, with attached notes (POS-Cu.doc) on copper levels in Sea-Tac Airport (STIA/POS) runway stormwater runoff and the need for further treatment. Notes discuss total recoverable (TR) copper concentrations (median 37 ug/l) from SEATAC runways versus the acute toxicity standard of 15 ug/l at hardness 100,
