Letter dated May 31, 2001 from NMFS Northwest Region to FAA Airport Division Manager Lowell H. Johnson (NMFS No. WSB-00-318) concurring with the ‘may affect, not likely to adversely affect’ determination for threatened Puget Sound chinook salmon (Onchorhynchus tshawytscha) and designated critical habitat under ESA Section 7(a)(2), and finding STIA projects ‘not likely to adversely

In May 2001, the National Marine Fisheries Service (NMFS) issued a biological opinion concluding that planned construction and expansion projects at Seattle-Tacoma International Airport — including a new 8,500-foot runway and other facility upgrades — were not likely to adversely affect threatened Puget Sound chinook salmon or their designated critical habitat. The review, requested by the FAA under the Endangered Species Act, examined potential impacts to nearby waterways such as Miller, Des Moines, and Gilliam creeks, as well as Essential Fish Habitat for coastal and groundfish species. NMFS concurred with the airport's own Biological Assessment, determining the projects could proceed with the mitigation measures proposed.

Letter dated May 31, 2001 from NMFS Northwest Region (Seattle, WA) to Lowell H. Johnson, FAA Airport Division Manager, concurring with the ‘may affect, not likely to adversely affect’ determination for threatened Puget Sound chinook salmon (Oncorhynchus tshawytscha) and designated critical habitat under ESA Section 7(a)(2) for Seattle-Tacoma International Airport (STIA) Master Plan Update Improvements

The U.S. Fish and Wildlife Service issued a biological opinion in May 2001 evaluating the potential effects of proposed Master Plan Update Improvements at Seattle-Tacoma International Airport on three protected species: bull trout, bald eagle, and marbled murrelet. The review was conducted under Section 7 of the Endangered Species Act at the request of the Federal Aviation Administration, which had determined the project was 'not likely to adversely affect' any of the three species. The opinion covers planned airport development in the cities of SeaTac and Des Moines, along with off-site wetland mitigation near the Green River in Auburn, Washington.

Essential Fish Habitat (EFH) Assessment prepared by Parametrix, Inc. for the Federal Aviation Administration and Port Of Seattle for Master Plan Update Improvements at Seattle-Tacoma International Airport (STIA), March 2001. Document AR049873 (project 556-2912-001) evaluates Pacific Coast salmon EFH — Chinook, Coho, and Puget Sound Pink salmon — in Miller Creek Basin, Des Moines Creek

The FAA's Airport Capacity Benchmark Report 2001 measures the maximum number of flights 31 of the nation's busiest airports can handle per hour under both good and adverse weather conditions. The benchmarks were developed between October 2000 and April 2001 by the FAA and MITRE/CAASD to help understand the relationship between airline demand and runway capacity, and to inform long-term aviation policy decisions. While useful as a reference point, the report notes that these benchmarks are starting points for discussion rather than definitive guides for major investment or scheduling decisions.

This December 2000 report assesses the impact of Seattle-Tacoma International Airport's Master Plan Update improvements on Pacific Coast salmon Essential Fish Habitat (EFH) in nearby waterways, including Miller Creek, Des Moines Creek, and the Green River Basin. Prepared by Parametrix, Inc. for the Federal Aviation Administration and the Port of Seattle, it evaluates water quality, aquatic habitat, and hydrological effects of airport expansion on local salmon species such as Chinook, Coho, and Pink salmon. The report also outlines conservation and mitigation measures proposed to offset adverse effects on salmon habitat in the airport's surrounding watersheds.
