Resume of Michael J. Cheyne, located at 1004 East Fourth Avenue, Ellensburg, Washington 98926. Cheyne served as Director of Planning and 3rd Runway Project Manager at Seattle-Tacoma International Airport (1989-present), Port Executive Director at Port of Edmonds (1986-1989), Port Executive Director at Port of Friday Harbor (1982-1986), and Manager at Newport Yacht Club in Bellevue

This document, labeled Exhibit 431 and bearing reference number AR 022780.01, is a photograph from the administrative record, appearing to show ground-level environmental conditions near a pipe or post, with visible soil, leaf litter, pine needles, and wet or saturated ground surface. The image likely documents site conditions relevant to environmental or noise mitigation proceedings associated with Seattle-Tacoma International Airport. No additional text or descriptive caption accompanies the photograph.

This document, labeled Exhibit #430 and archived as AR 022780, is a photograph showing what appears to be a ground-level view of a wet or muddy outdoor area with debris, sticks, and small plants visible. A white pipe or tube is partially visible in the lower left corner of the image. The photo appears to have been submitted as evidence or documentation in a proceeding related to Sea-Tac Airport noise or environmental policy matters.

Declaration of Michael Cheyne, Port Of Seattle project manager for the Sea-Tac third runway construction, filed in PCHB case No. 01-133 (Airport Communities Coalition v. Department of Ecology and Port Of Seattle). Cheyne describes his role overseeing administration, planning, design, and construction of the Sea-Tac third runway as part of the Master Plan Update (MPU).

Declaration of John J. Strunk (geologist, Associated Earth Sciences Inc., AESI) filed in PCHB No. 01-133, Pollution Control Hearings Board for the State of Washington, supporting Port Of Seattle’s response opposing Airport Communities Coalition (ACC) motion for stay. Strunk details AESI’s groundwater evaluation at Seattle-Tacoma International Airport (STIA), including work on the Aircraft Operations and

This document outlines a Water Quality Assessment (WQA) conducted in support of the Port of Seattle's Master Plan Update for Seattle-Tacoma International Airport (STIA), focused on evaluating the airport's ability to meet water quality requirements under its NPDES permit following construction of a proposed third runway. The assessment uses three approaches: a Water Effect Ratio (WER) study to adjust water quality standards for site-specific conditions, a mixing zone analysis to determine where standards must be met in receiving streams, and an examination of variability in stormwater quality. The goal is to reach agreement with the Washington Department of Ecology on whether aquatic life in nearby receiving streams will be adequately protected.

This research study examines how heavy metals in highway stormwater runoff behave as water flows off pavement, finding that most heavy metals remain dissolved rather than attaching to solid particles due to low alkalinity and short travel times on the pavement surface. The study, conducted on Interstate 75 in Cincinnati over two years, explores how best management practices like detention basins or infiltration trenches could be used to capture these metals before they reach receiving waters.

This document is a reference bibliography (Exhibit B) listing scientific and regulatory sources related to environmental monitoring at Seattle-Tacoma International Airport. It includes studies on stormwater quality, aircraft de-icing and anti-icing fluid toxicity, aquatic habitat assessment, and sediment guidelines, drawn from sources such as the Port of Seattle, Parametrix Inc., and various environmental agencies. The references support environmental compliance reporting under the airport's NPDES stormwater permit.
