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.

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.
