Winter Use Plan, Final Environmental Impact Statement, Yellowstone National Park, Idaho, Montana, and Wyoming

Pursuant to the National Environmental Policy Act of 1969, the National Park Service (NPS) announces the availability of a Final Environmental Impact Statement (EIS) for a Winter Use Plan for Yellowstone National Park, located in Idaho, Montana, and Wyoming. The EIS evaluates eight alternatives, and identifies the Preferred Alternative as Alternative 8, a one-year plan to allow oversnow vehicle use in the park for the winter of 2011/2012, at the same levels (up to 318 commercially guided, best available technology snowmobiles and 78 commercially guided snowcoaches per day) that were allowed under the interim regulation in place for the winters of 2009/ 2010 and 2010/2011. NPS intends to supplement this EIS next year, in order to make a long-term decision prior to the 2012/2013 winter season.
