A December 2001 letter from Azous Environmental Sciences challenges the Port of Seattle's wetland mitigation plan for the SeaTac Third Runway construction project, arguing that the plan inadequately offsets environmental damage to wetlands and streams. The letter contends that the Port has misclassified wetland 'enhancement' work at Vacca Farm as 'restoration,' inflating mitigation credits, and that the overall plan fails to meet no-net-loss standards required under Army Corps of Engineers regulations.

AR027061. Two letters dated December 2001 regarding NPDES Permit WA-002465-1 for Seattle-Tacoma International Airport. First: Washington Department of Ecology (Tricia Miller, Permit Coordinator, Northwest Regional Office) acknowledges receipt of a waste discharge permit application from Michael Feldman, Director of Aviation Facilities, Port Of Seattle, received December 21, 2001; contact Ed Abbasi at (425) 649-7227. Second

Letter dated December 27, 2001 from Keith R. Smith, Water Resources Manager at Port Of Seattle Seattle-Tacoma International Airport, to Ms. Ann Kenny at Washington State Department of Ecology (Bellevue, WA 98088-5452), transmitting construction stormwater monitoring reports for September, October, and November 2001 under Section K.6 of Water Quality Certification No. 1996-4-02325 (Amended-1) and NPDES

The Port of Seattle submitted formal objections and responses to interrogatories filed by the Airport Communities Coalition (ACC) before Washington State's Pollution Control Hearings Board, related to a legal dispute over the Port's Third Runway Project. The case centered on the Department of Ecology's water quality certification issued under federal Clean Water Act Section 401. The document outlines the legal procedures governing the exchange of information between the parties during the hearing process.

This document contains the Port of Seattle's formal objections and responses to interrogatories and requests for production filed by the Airport Communities Coalition (ACC) before Washington State's Pollution Control Hearings Board (Case No. 01-160). The Port identifies over a dozen expert witnesses it intends to call, including specialists in geotechnical engineering, toxicology, hydrology, and groundwater science from firms such as Parametrix, Inc., Hart Crowser, and ENSR Toxicology. The case centers on environmental and pollution concerns related to Sea-Tac Airport operations.

This legal document contains the Port of Seattle's responses to interrogatories filed by the Airport Communities Coalition (ACC) before Washington State's Pollution Control Hearings Board. The Port identifies expert witnesses expected to testify on topics including contaminated site cleanup, stormwater quality, wetland mitigation, and environmental review under SEPA and NEPA for Sea-Tac Airport's Master Plan Update projects. The document outlines each expert's anticipated testimony and the basis for their opinions in connection with Clean Water Act permit requirements.

ACC (Airport Communities Coalition) motion for partial summary judgment filed in PCHB No. 01-160 against State of Washington Department of Ecology and Port of Seattle, arguing the Section 401 Certification should be invalidated because the Port lacks a water right to permanently mitigate low-flow impacts of the Sea-Tac Airport third runway project. Cites PCHB December

This document is a deposition of Edward O'Brien, taken on December 21, 2001, as part of a Pollution Control Hearings Board case in Washington State involving the Airport Communities Coalition challenging the Department of Ecology and the Port of Seattle. O'Brien discusses stormwater management techniques, including infiltration facilities, which can be used to treat stormwater quality and mitigate low-flow impacts on surface water systems connected to groundwater. He explains that while infiltration can delay and filter stormwater flows through soil profiles, precise control over timing and flow rates is limited and depends on site-specific soil and hydrological conditions.

This December 2001 letter from the U.S. Fish and Wildlife Service's Western Washington office provides detailed comments on a Monitoring Plan for Embankment Fill Seepage related to a Sea-Tac Airport Master Plan Update, reviewed under the Endangered Species Act. The agency requested key revisions, including monitoring both seepage quality and quantity, beginning monitoring when seepage first occurs rather than after embankment completion, and ensuring groundwater wells are considered as a monitoring pathway. The letter also clarified that any exceedances of water quality criteria must be reported promptly, and that the Federal Aviation Administration—not the Port—would be responsible for reinitiating formal consultation.

Memorandum dated December 20, 2001 from Michael Bailey, P.E. and Reda A. Mikhail, P.E. of Hart Crowser, Inc. to Jim Thomson, P.E. of HNTB Corporation regarding AR053223, project 4798-40. Analyzes sensitivity of MSE (Mechanically Stabilized Earth) wall design to variations in soil shear modulus under dynamic/seismic loading for the Third Runway Project at Sea-Tac Airport,
