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.

Greg Wingard, an environmental consultant and Executive Director of Waste Action Project, submitted this declaration in a 2001 Pollution Control Hearings Board appeal challenging a permit modification for Seattle-Tacoma International Airport's stormwater discharges. Wingard argues that the modified NPDES permit failed to identify the specific locations of new discharge outfalls into local waterways including Miller, Des Moines, Gilliam, and Walker Creeks, preventing meaningful public participation and environmental review. He contends that without knowing where discharges will occur, it is impossible to evaluate potential cumulative impacts on downstream waterways and riparian property owners.

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.

Joseph Brascher, a hydrologic modeling expert at Aqua Terra Consultants, submitted this declaration in a 2001 Washington State Pollution Control Hearings Board case involving the Port of Seattle's Master Plan Update for Sea-Tac International Airport. He describes how the HSPF (Hydrologic Simulation Program – Fortran) computer model was used to analyze stormwater runoff and flow impacts on Miller and Walker Creeks resulting from planned airport construction. The declaration also outlines additional studies and design details requested by the Washington State Department of Ecology as conditions of its §401 water quality certification for the project.

Exhibit 175 (AR018443) summarizes wetland mitigation credit for Sea-Tac Airport Master Plan Update improvements. Tables detail in-basin mitigation (102.27 acres, 29.80 credit) and out-of-basin mitigation (65.38 acres, 42.91 credit) for a total of 167.65 acres and 72.71 mitigation credits. Specific mitigation sites include Vacca Farm, Miller Creek Wetland and Riparian Buffer, Tyee Valley Golf Course,
