TagThird Runway(1068)

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.

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.

A May 2001 letter from the Port of Seattle's Environmental Program Manager to the Washington Department of Ecology provides a quarterly update on fill material placed at the Sea-Tac Airport Third Runway Embankment project. The letter presents final tonnage and calculated volumes of soil placed during the Phase III Embankment contract (May 2000 through February 2001), noting no new fill sources were received in the first quarter of 2001. An attached summary table lists all fill sources, suppliers, categories, and final volumes consistent with the 1999 Airfield Project Soil Fill Acceptance Criteria.

An independent wetland scientist, writing on behalf of the Airport Communities Coalition, raised concerns with the US Army Corps of Engineers about potential mapping errors affecting Wetland 44a near the proposed SR509 Temporary Interchange for Sea-Tac Airport's Third Runway project. The letter warned that discrepancies between engineering drawings and actual field conditions could mean the wetland was closer to the construction zone than documented, risking illegal filling or sediment discharge into protected wetlands. The scientist urged the Corps to verify the wetland's true location and review erosion control measures before approving any construction permits.
