April 9, 1998 letter from Gary Oldenburg, USDA Animal and Plant Health Inspection Service (APHIS) Wildlife Services State Director for WA/AK/HI/Pacific Islands, to Jonathan Friedman, U.S. Army Corps of Engineers Seattle District, regarding wildlife hazards at Sea-Tac Airport. Argues that wetland mitigation measures at SeaTac Airport should be conducted off-site, citing FAA Advisory Circular 150/5200-33

A 1998 letter from Fisheries Consultants to the U.S. Army Corps of Engineers concludes that SeaTac Airport's proposed Third Runway will have an overall neutral effect on aquatic habitat and fish populations in Miller Creek. Minor benefits are expected from new storm flow detention facilities, which will reduce peak flood flows by 5–20%, and from a planned 100-foot-wide stream buffer created through residential buyouts along the creek. Adverse impacts are limited to the temporary disruption of a quarter-mile creek relocation and an approximate 8% reduction in late-summer low stream flows due to increased paved surfaces and wetland fill.

Comment Binder A compiled by Port of Seattle for Sea-Tac Airport (Seattle-Tacoma International Airport) third runway project, containing letters submitted to the U.S. Army Corps of Engineers during the initial comment period (December 19, 1997 to January 20, 1998) and comments from the joint Corps/Ecology public hearing held April 9, 1998. Includes a January 15,

US Army Corps of Engineers Seattle District public notice of permit application 96-4-02325, filed by Port Of Seattle (contact: Barbara Hinkle, (206) 439-6606) under Section 404 of the Federal Clean Water Act. Proposes filling 7.38 acres of wetlands to construct an 8,500-foot parallel third runway at Seattle-Tacoma International Airport (Sea-Tac), plus 2.34 acres for Runway

This 1997 report by Science Applications International Corporation characterizes sediment quality in the Duwamish Turning Basin near Seattle, Washington, as part of the Hamm Creek Restoration Project. It presents results from chemical testing, biological bioassays, and sediment sampling to evaluate contaminant levels and compare them against sediment management standards. The study was prepared for the U.S. Army Corps of Engineers, Seattle District.

In December 1996, the Port of Seattle submitted a Section 404 permit application to the U.S. Army Corps of Engineers to place fill material into wetlands at Seattle-Tacoma International Airport as part of its Master Plan Update, which included construction of a third parallel runway. The proposed runway, located 2,500 feet west of the existing runways, was intended to address severe arrival delays during poor weather conditions, which reduced airport capacity from 60 to as few as 24 arrivals per hour roughly 44% of the year. The application was the result of nearly a decade of regional planning, environmental review, and public involvement, including studies confirming that no feasible supplemental airport sites existed in the four-county region.

In December 1996, the Port of Seattle submitted a Section 404 permit application to the U.S. Army Corps of Engineers to place fill material in waters of the United States as part of Sea-Tac Airport's Master Plan Update, which included construction of a third parallel runway. The application explains that the new runway, located 2,500 feet west of the existing 16R/34L runway, was needed to reduce severe arrival delays during poor weather conditions, which were costing airlines approximately $42 million annually. The project was the outcome of nearly a decade of regional planning, including the PSRC's Flight Plan Study, which evaluated numerous alternatives before recommending the runway expansion as the best solution for the region's long-term air travel needs.
