Notes
This biological opinion from the U.S. Fish and Wildlife Service addresses the effects of the proposed Master Plan Update Improvements (MPUI) for Seattle-Tacoma International Airport on the threatened bull trout, bald eagle, and marbled murrelet under Section 7 of the Endangered Species Act. The opinion covers FAA and Army Corps of Engineers actions including a third runway embankment fill, taxiway construction, wetland impacts, and associated mitigation near the Green River in Auburn. The project would permanently fill approximately 18.37 acres of wetlands on-site with mitigation including restoration of over 74 acres of wetlands in-basin and out-of-basin.
