Yellowstone Final Winter Use Plan/Environmental Impact Statement

The National Park Service (NPS) has released a Final Environmental Impact Statement (EIS) for a Winter Use Plan for Yellowstone National Park. 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. This plan would be in effect only for the 2011/2012 winter season.
