## Abstract

The National Park Service (NPS) is postponing the implementation of some existing snowmobile regulations in Yellowstone National Park, the John D. Rockefeller, Jr., Memorial Parkway, and Grand Teton National Park for one year. This additional time is needed because the NPS has not had sufficient time to plan for and implement the NPS-managed, mass-transit, snowcoach-only system outlined in the existing Winter Use Plan and Record of Decision and to complete the Supplemental Environmental Impact Statement (SEIS).
