EXH AR023116: Rebuttal to Response to 401/404 Comments, Miller Creek Relocation Project, STIA Master Plan Update

A biologist from Columbia Biological Assessments submitted a rebuttal in June 2001 challenging the Port of Seattle's environmental justifications for proposed construction improvements at Seattle-Tacoma International Airport. The letter argues that the Port failed to adequately assess impacts on Miller Creek, particularly regarding fish habitat, water temperature, and dissolved oxygen levels in a relocated section of the creek. The author contends that no proper baseline survey of fish and aquatic life was conducted, making regulatory approval of the project scientifically premature.

Notes

Letter dated June 20, 2001, from John A. Strand, Ph.D., Principal Biologist, Columbia Biological Assessments (Richland, WA), to U.S. Army Corps of Engineers Regulatory Branch (Muffy Walker, Gail Terzi) and Washington State Department of Ecology Shorelands and Environmental Assistance Program (Ann Kenny), rebuting the Port of Seattle’s April 30, 2001 response to 401/404 comments on permit reference 1996-4-02325. Subject is the Miller Creek Relocation Project as part of the Master Plan Update Improvements (MPU) at Seattle-Tacoma International Airport (STIA). Strand challenges the Port’s failure to conduct quantitative fish surveys to establish baseline conditions, disputes adequacy of dissolved oxygen and temperature analysis for cutthroat trout habitat, and critiques the Natural Resource Mitigation Plan (Parametrix 2000a) and associated EIS documents including the Wetland Functional Impact Analysis and Sea-Tac Runway Fill Hydrological Studies. Argues that riparian shading, summer flow conditions, and D.O. levels will not support fish habitat in the short or long term. Administrative Record number AR023116-AR023118. Filed in PCHB Third Runway EIS context.
