This October 2000 laboratory report from Columbia Analytical Services presents water and sediment quality monitoring results for samples submitted by Columbia Biological Assessments in Richland, Washington. The report includes data qualifiers and acronym definitions for interpreting inorganic, metals, and organic analysis results. All analyses were conducted under the laboratory's quality assurance program and assigned service request number K2006704.

Washington State Department of Ecology letter dated September 29, 2000, to Colonel Randall J. Butler (Army Corps of Engineers, Portland District) and Lee Daneker (EPA Aquatic Management Division) denying without prejudice a Section 401 Clean Water Act water quality certification for the Columbia River Channel Improvements project. The two proposed actions were: (1) deepening the

Internal deliberative email chain dated September 27, 2000, among Washington State Department of Ecology staff Tom Luster, Raymond Hellwig, Kevin Fitzpatrick, Joan Marchioro (ATG), and Erik Stockdale, marked Attorney Client Privileged. Discusses draft denial letter and withdrawal letter related to the Dinsmore 401 water quality certification review for a Port Of Seattle project (Sea-Tac Airport).

A September 26, 2000 letter from Water Resources Consulting L.L.C. to the Washington State Department of Ecology critiques the Port of Seattle's plans to augment water flow in Des Moines Creek, a project related to Sea-Tac Airport operations. The letter identifies several serious flaws in the proposal, including the lack of a secured water source, concerns about water temperature and fluoride toxicity to fish, and a maintenance-intensive design prone to failure. The author concludes that the Port's 'preliminary design' does not provide reasonable assurance that water quality standards will be met.

A water resources consultant hired by the Airport Communities Coalition reviewed Sea-Tac Airport's August 2000 Stormwater Master Plan and found it seriously deficient in protecting local water quality. The review concludes that existing pollution controls at the airport are not working, that stormwater discharges regularly violate Washington State Water Quality Standards, and that the Plan's proposed measures fail to provide reasonable assurance that those standards will be met in the future. Key concerns include the diversion of polluted runoff away from local creeks, inadequate handling of metal roof runoff, and the lack of meaningful mass-balance accounting for long-lived pollutants.
