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.

Reference list compiled by Peter Willing, Ph.D., of documents relied upon in testimony regarding the 401 Water Quality Certification for the Third Runway at Sea-Tac Airport. Sources cited include studies on highway runoff chemistry, heavy metals partitioning, urban stormwater BMPs, treatment wetlands, NPDES permits, and Port of Seattle annual stormwater monitoring reports (1998–2001). Key references

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.

This document outlines wetland mitigation calculations for the Vacca Farm site, detailing compensation actions such as wetland restoration and enhancement across various locations including Lora Lake and prior converted croplands. Adjustments were made to credit acreages based on state ecology findings and documentation gaps; for example, the 6.60-acre converted cropland credit was reduced to 3.30 acres because the state identified those areas as existing wetlands requiring enhancement ratios rather than restoration ratios. In total, the site's original 10.48 credit acres were adjusted down to 5.61 acres after accounting for these regulatory and documentation considerations.

This document outlines the Port of Seattle's step-by-step process for applying water quality standards at a specific site, focusing on copper toxicity testing in local waterways. The flowchart guides researchers through a series of studies — including screening, range-finding, and definitive toxicity tests using waterfleas and fathead minnows — to determine whether copper levels in outfall and receiving waters pose environmental risks. Depending on test results and regulatory approval from the Washington State Department of Ecology, the process may lead to a Water Effect Ratio (WER) study or a Translator Study.
