This document is the professional curriculum vitae of Dyanne Sheldon, principal of Sheldon & Associates, Inc., a Seattle-based wetland ecology consulting firm. Among her relevant work, she co-authored both the Sea-Tac Airport Wetland Inventory and the Sea-Tac Airport Wetland Management Plan in 1991 for the Port of Seattle's Environmental Management Section. Her broader expertise spans wetland delineation, habitat restoration, environmental planning, and regulatory compliance across the Pacific Northwest.

This document provides a professional biography and project portfolio for Amanda Azous, an environmental scientist and sole proprietor of Azous Environmental Sciences based in Washington State. Her work focuses on wetland delineation, ecological restoration, watershed analysis, and land use planning, primarily in the San Juan County and Puget Sound regions. While her expertise informs broader environmental policy in Washington State, this document contains no information directly related to Sea-Tac Airport noise policy.

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.

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.

This document is the curriculum vitae of Dr. Peter Willing, a water resources consultant based in Bellingham, Washington, who was retained to review surface and ground water hydrology related to the possible construction of a third runway at Sea-Tac Airport from November 1999 to February 2001. His investigation addressed issues including stormwater management effectiveness, compliance with the King County Surface Water Design Manual, and potential project effects on wetlands, stream flows, and anadromous fish. Dr. Willing holds a Ph.D. from Cornell University and has broad experience in flood analysis, water rights, and geohydrologic investigations across the Pacific Northwest.

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.
