    EXH AR021263: WAC 173-201A WA Water Quality Standards — Toxic, Radioactive, Lake Nutrient

    This document outlines Washington State water quality standards for surface waters, including criteria for total phosphorus levels in lakes across different ecoregions (Cascades and Columbia Basin) and limits for toxic substances such as heavy metals, pesticides, and radioactive materials. It establishes trophic state classifications and action values that trigger lake-specific studies when exceeded, and sets numerical criteria for aquatic life protection in both freshwater and marine environments.

    EXH 345: Curriculum Vitae Peter Willing PhD Water Resources Consulting LLC

    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.

    EXH AR021068: Declaration Greg Wingard — CASE v. Ecology & Port, PCHB No. 01-090

    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.

    EXH 335: Declaration James C. Kelley PhD — Wetland Impacts Mitigation STIA Master Plan Update PCHB 01-133

    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.

    Exhibit 197: Declaration of Joseph Brascher — HSPF Hydrologic Modeling, Miller and Walker Creeks, STIA Master Plan Update

    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.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
