Yellowstone Airport Terminal EA
Welcome to the Yellowstone Airport, West Yellowstone, Montana
Virtual Self-guided Open House for Terminal Improvements Environmental Assessment (EA)
The Montana Department of Transportation – Aeronautics Division (MDT – Aeronautics) (Airport Sponsor) owns and operates the Yellowstone Airport (WYS) (Airport) near West Yellowstone, Montana. The Airport Sponsor is proposing improvements (Proposed Action) at the airport that would provide an updated and safe terminal building and associated improvements to meet existing and forecasted passenger and terminal user needs. As a result of implementing new terminal improvements, an ancillary purpose is to improve the water, sewer, and fiber optic infrastructure to better serve the new terminal. Such improvements and modifications must be made to comply with Federal Aviation Administration (FAA) design standards.
The draft Environmental Assessment (EA) identifies the potential environmental impacts associated with the Proposed Action, as well as how any identified impacts could be avoided, minimized, or mitigated. The EA has been prepared pursuant to FAA requirements for compliance with the National Environmental Policy Act (NEPA) as the FAA is the lead agency for this EA. As the Proposed Action would include improvements on the Custer Gallatin National Forest and require a special use authorization from the USFS, the USFS is a cooperating agency in the preparation of this EA. Since the State of Montana owns and operates the Yellowstone Airport, the Proposed Action is also subject to the Montana Environmental Policy Act (MEPA).
