A biologist with Columbia Biological Assessments submitted a formal rebuttal in June 2001 challenging the Port of Seattle's environmental responses related to proposed Master Plan Update Improvements at Seattle-Tacoma International Airport. The rebuttal argues that the Port failed to adequately assess impacts on Miller Creek, particularly regarding fish habitat, water temperature, and dissolved oxygen levels during summer months. The author contends that no proper baseline survey of fish and aquatic organisms was conducted, making regulatory approval and proposed mitigation measures scientifically insufficient.

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.
