Letter dated January 25, 2001 from Peter M. Douglass, P.E. (Technical Review Board Facilitator) to U.S. Army Corps of Engineers (Jonathan Freedman, Project Manager) and Washington State Department of Ecology (Ann Kenny, Environmental Specialist) summarizing findings of an independent expert panel convened by Port Of Seattle to review embankment fill and mechanically stabilized earth (MSE)

The Port of Seattle requested regulatory approval to temporarily take Lagoon #3, part of Seattle-Tacoma International Airport's industrial wastewater treatment system, out of service from April through December 2002 for remediation and expansion work. The project aimed to increase the lagoon's storage capacity from 26 million gallons to 76 million gallons, add a protective liner, and rebuild berms to prevent untreated wastewater from seeping into the ground. During the construction period, some untreated industrial wastewater flows could potentially be released into Des Moines Creek as unavoidable bypasses.

A January 2001 letter and accompanying meeting notes document communications between the Port of Seattle and the Washington Department of Ecology regarding a groundwater contamination study at Seattle-Tacoma International Airport, conducted under the Model Toxics Control Act (MTCA) Agreed Order 97TC-N112. The records outline the scope of the study, which focuses on hydrogeologic investigation and a review of the Fuel Operations Area, and clarify that any necessary cleanup would be handled separately after the study's completion. Both parties discussed concerns about scope expansion and the process for addressing contaminated sites identified through the study.

United Airlines formally disagreed with a proposed use of Passenger Facility Charge (PFC) funds totaling $104.3 million toward a $587.4 million third runway construction project at Seattle-Tacoma International Airport. The airline argued that the runway would not meaningfully improve national air transportation capacity, safety, or competition, noting that less than 30 seconds of average delay could actually be attributed to the absence of a third runway. United also raised concerns about potential improper diversion of federal transportation funds and warned that approving the project before its full costs were understood would set a harmful precedent.
