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.
