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

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.

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

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,

A July 27, 2000 letter from the Port of Seattle's Environmental Program Manager transmits environmental documentation to the Washington Department of Ecology regarding fill material used in the Sea-Tac Airport Third Runway Project during the second quarter of 2000. The documentation, developed in accordance with the 1999 Airfield Project Soil Fill Acceptance Criteria, includes a fill summary table listing sources such as borrow pits, port property transfers, and construction sites, along with estimated fill volumes. A cumulative fill summary is also provided, covering all fill material placed from January 1998 through December 1999.

In July 2000, the Port of Seattle submitted an Implementation Plan to the Washington Department of Ecology outlining a proposed flow augmentation facility for Des Moines Creek, located near Seattle-Tacoma International Airport. The plan described using water from a Port-owned well to increase stream flow to one cubic foot per second and reduce water temperatures to 16 degrees Celsius during summer low-flow periods, with the goal of improving water quality and aquatic habitat. The facility would involve reconfigured well pumps, an 800-foot pipeline, a stilling basin, and an automated monitoring station to regulate flow and temperature in the creek.

In July 2000, the Port of Seattle submitted an Implementation Plan to the Washington Department of Ecology outlining a proposed Des Moines Creek Flow Augmentation Facility near Seattle-Tacoma International Airport. The plan describes using water from a Port-owned well — currently used for golf course irrigation — to boost creek streamflow to at least one cubic foot per second and lower water temperatures to 16°C during summer low-flow periods. An automated monitoring station downstream would control pump operations, with a backup option to draw from the Port's municipal water distribution system if well water became unavailable.
