This legal declaration by fish biologist Donald E. Weitkamp was submitted to Washington's Pollution Control Hearings Board in a case involving Seattle-Tacoma International Airport's expansion, including a proposed third runway. Weitkamp argues that the project's stormwater controls and water quality conditions under the §401 Certification are adequate to protect nearby streams, and disputes claims that salmon species are present near the airport's property along the headwaters of Miller, Walker, and Des Moines Creeks. He contends that these streams have already been significantly altered by surrounding urban development, making them more suitable for warm-water fish species than for salmonids.

Fish biologist Donald E. Weitkamp submitted this declaration opposing a legal challenge to Sea-Tac Airport's expansion plans, arguing that the airport's stormwater controls and water quality measures adequately protect nearby streams. He concluded that the headwater portions of Miller, Walker, Des Moines, and Gilliam Creeks near the airport are unlikely to support chinook or chum salmon, as urbanization has altered those streams to favor warm-water species instead. The declaration supports the Port of Seattle's position that its Master Plan Update projects meet environmental standards and will not significantly harm local aquatic resources.

This document is a professional biography and project experience summary for Dr. Don Weitkamp, a fisheries biologist with a Ph.D. from 1976, who has spent decades studying salmon habitat, water quality, and shoreline restoration in the Pacific Northwest. His work has focused on rivers, estuaries, and coastal areas including Commencement Bay, the Green-Duwamish River, and Elliott Bay, involving biological assessments, habitat restoration, and hydroelectric dam impacts. This document does not contain information related to Sea-Tac Airport noise policy.

This document contains the Port of Seattle's formal objections and responses to interrogatories filed by the Airport Communities Coalition (ACC) before Washington State's Pollution Control Hearings Board (Case No. 01-160). The Port identifies over a dozen expert witnesses it intends to use, including specialists in geotechnical engineering, toxicology, hydrology, and groundwater science from firms such as Parametrix, Inc. and Hart Crowser, Inc. The case involves a dispute between the ACC and the Port of Seattle regarding environmental and pollution control issues related to Sea-Tac Airport operations.

In this 2001 declaration filed with Washington State's Pollution Control Hearings Board, fisheries biologist Dr. John A. Strand argues that proposed modifications to the Port of Seattle's stormwater discharge permit would harm Walker and Gilliam Creeks near Sea-Tac Airport, which support salmon, trout, and other aquatic life. Dr. Strand contends that Ecology failed to identify specific locations of new construction-related stormwater outfalls, denying the public a meaningful chance to assess environmental impacts. He supports a stay of the permit modification until its compliance with the Clean Water Act can be fully reviewed.

In this legal declaration, ecologist James C. Kelley, Ph.D., testifies about the environmental impact of Seattle-Tacoma International Airport's Master Plan Update, which permanently fills 18.37 acres of wetland. He describes a comprehensive mitigation plan designed to replace lost ecological functions in the Miller, Walker, and Des Moines Creek basins. Kelley also notes that the affected wetlands and streams were already significantly degraded by decades of logging, farming, and urban development before the airport expansion.
