This is a catalogued index of documents from 2001 related to the proposed Third Runway at Seattle-Tacoma International Airport, covering regulatory filings, public comments, and environmental studies. It includes records from agencies such as the Department of Ecology, the Corps of Engineers, and King County, addressing topics like stormwater management, NPDES permits, groundwater studies, and the impact of the February 2001 Nisqually Earthquake on airport structures. The catalog serves as a reference guide directing researchers to archival notebooks and specific shelf locations where the full documents are stored.

The 2000 Puget Sound Water Quality Management Plan, adopted December 14, 2000, outlines coordinated local, state, tribal, and federal actions to restore and protect the health of Puget Sound in Washington State. The plan introduces new programs addressing aquatic nuisance species and Georgia Basin water coordination, while substantially revising existing stormwater, habitat, and wetlands protection programs. It builds on earlier management plans dating back to 1987 and calls for renewed commitment to funding and policy improvements.

This March 2000 report, prepared by Washington State health and environmental agencies, examines whether jet engine exhaust emissions from Seattle-Tacoma International Airport can be monitored or modeled using wind and takeoff data. It reviews previous air quality studies, outlines health and environmental justice concerns for nearby communities, and recommends a structured air quality monitoring study with specific methods, data analysis approaches, and estimated costs. The report was developed in consultation with community representatives, the EPA, and local universities.

This 1998/1999 study by the Washington State Department of Ecology monitored levels of oxides of nitrogen and particulate matter in the SeaTac area, likely in relation to emissions from Seattle-Tacoma International Airport and surrounding traffic. Prepared by Jim Frost and Doug Knowlton of Ecology's Air Program, the report assessed local air quality conditions during that period. It serves as a technical reference for understanding pollution levels near the airport in the late 1990s.

A 1999 University of Washington study measured nitrogen dioxide (NO2) levels around Seattle-Tacoma International Airport to determine whether aircraft operations were harming local air quality. Researchers found that NO2 levels at all monitoring sites remained well below federal safety standards, and that regional conditions and nearby freeways — not aircraft — were the primary drivers of local pollution. The study concluded that airport operations had only a small, difficult-to-isolate effect on community NO2 levels, estimated at less than 7 parts per billion above background levels.

This Washington State Department of Ecology report outlines stormwater erosion and sediment control requirements for large construction projects involving one or more acres of disturbed land in the Puget Sound Basin. It describes best management practices (BMPs) such as covering exposed soil, trapping sediment onsite, and protecting adjacent properties from runoff and sediment. Developers are required to create an erosion and sediment control plan and are financially responsible for its implementation.

A May 1991 Washington State Department of Ecology study, requested by state Representative Greg Fisher, identified Seattle-Tacoma International Airport as a major indirect source of air pollution, responsible for approximately 8% of carbon monoxide and 5% of nitrogen oxide emissions in King County. The report found that idling jets on the runway were the primary source of carbon monoxide, while aircraft climb and approach operations generated the most nitrogen oxide, with local pollution hotspots identified near South 154th Street, Seattle Christian School, and Tyee Golf Course. The study recommended minimizing runway queuing, reducing airport automobile traffic, exploring alternative fuels for ground support vehicles, and conducting further ground-level air quality testing around the airport.

This 1989 annotated bibliography from the Puget Sound Water Quality Authority catalogs agency publications related to Puget Sound water quality, covering topics such as nonpoint source pollution, shellfish safety, oil spills, and stormwater management. It lists reports, newsletters, and pamphlets from federal, state, and local agencies—including the EPA, Washington Department of Ecology, and various county departments—along with contact information for obtaining each document. The bibliography serves as a resource guide for researchers, planners, and community members concerned with environmental water quality issues in the Puget Sound region.
