In this April 11, 2001 letter, Washington State Department of Ecology Director Tom Fitzsimmons responds to attorney Kevin Stock regarding concerns raised by the Airport Communities Coalition (ACC) about the Port of Seattle's proposed Third Runway. Ecology agrees to host a technical meeting with ACC experts to examine whether Third Runway infrastructure could create pathways for contaminants from the Airport Operations and Maintenance Area (AOMA) to proposed runway sites, but declines to halt the 401 water quality certification process pending completion of a separate groundwater study. Ecology assures the ACC that it will not approve or deny the Third Runway projects until a 'pathway' analysis addressing contamination concerns is completed.

In an April 2001 letter to the Washington State Department of Ecology, Northwest Hydraulic Consultants raised serious concerns about the adequacy of a low streamflow analysis conducted for the proposed third runway expansion at Seattle-Tacoma (Sea-Tac) Airport. The firm argued that Ecology's March 2001 review memo effectively endorsed the study's methods and conclusions without addressing significant technical flaws, including the use of future rather than existing basin conditions and the failure to account for impacts from gravel mining, lagoon lining programs, and embankment seepage. The consultants, representing the Airport Communities Coalition, requested that Ecology revisit its review, consider all submitted technical comments, and require the airport's applicant to formally respond to outstanding concerns before any regulatory certification was granted.

This 2001 draft report by Parametrix, Inc. describes a water quality study conducted for the Port of Seattle to assess the feasibility of meeting state water quality standards following construction of a third runway at Seattle-Tacoma International Airport. The study focused on developing a site-specific water-effect ratio (WER) for copper in Miller, Walker, and Des Moines Creeks by conducting toxicity bioassays on stormwater samples collected during storm events. The report summarizes results from initial screening and range-finding phases, with the final site-specific water quality standard still pending completion at the time of publication.

This February 2001 report by Herrera Environmental Consultants presents a five-year summary of water quality monitoring conducted for the City of Des Moines, Washington, covering three creek basins: Des Moines Creek, Massey Creek, and North Fork McSorley Creek. The report examines a range of water quality parameters including temperature, pH, dissolved oxygen, metals, nutrients, turbidity, and fecal coliform bacteria, as well as benthic invertebrate conditions as indicators of stream health. It was prepared for the City's Surface Water Management Utility and provides data intended to inform stormwater and surface water management decisions in the Des Moines area near Sea-Tac Airport.
