Seven alternatives were considered in the DEIS. Alternative 1 would not permit public over-snow vehicle (OSV) use in Yellowstone after the interim rule expires (after the winter 2010/2011), but would allow for approved non-motorized use to continue. Alternative 1 has been identified as the environmentally preferable alternative. Alternative 2 would manage OSV use at the same levels as the 2008 interim rule (318 snowmobiles and 78 snowcoaches per day). Alternative 3 would allow for snowmobile and snowcoach use levels to increase to the levels set forth in the 2004 plan (720 snowmobiles and 78 Start Printed Page 27088snowcoaches per day). Alternative 4 would allow for commercially guided wheeled vehicles, in addition to OSVs (100 commercially wheeled vehicles, 110 snowmobiles and 30 snowcoaches per day). Alternative 5 would initially allow for the same level of use as alternative 2 (318 snowmobiles and 78 snowcoaches per day), but would provide for a transition to snowcoaches only if user demand is present to support such a transition or at the discretion of the Superintendent. Upon complete transition, there would be zero snowmobiles and up to 120 snowcoaches per day. Alternative 6 would provide for use levels that vary each day, with a seasonal limit of up to 32,000 snowmobiles and 4,600 snowcoaches, and a daily limit of up to 540 snowmobiles and 78 snowcoaches. Up to 25 percent of snowmobile permits under alternative 6 would be for unguided or non-commercially guided use.

Alternative 7 is the agency preferred alternative and would provide a variety of use levels and experiences for visitors. Four different use levels for snowmobiles and snowcoaches would be implemented, the combination of which may vary by day. Snowmobile use would range from 110 to 330 vehicles per day and snowcoach use would range from 30 to 80 vehicles per day. The varying use levels would provide for high and low use days, allowing for a variety of motorized and non-motorized visitor experiences throughout the winter season. Commercial guide requirements would continue. All snowmobiles and snowcoaches would need to enter the park by 10:30 a.m. A requirement to limit nitrogen oxides (NOX) emissions would be added to the current Best Available Technology requirements for snowmobiles. By 2014-2015, all snowcoaches would have to employ model year 2010 engine and emission control systems, and all snowcoaches' sound would be limited to 73 decibels, similar to the current BAT requirements for snowmobiles. During the first winter of implementation, the provisions of the interim plan that was in effect for the past two winters would continue. Up to 318 best available technology, commercially guided snowmobiles and up to 78 commercially guided snowcoaches would be allowed to enter the park each day during the transition winter.

More information regarding Yellowstone in the winter, including educational materials and a detailed history of winter use in Yellowstone, is available at​yell/​planvisit/​winteruse/​index.htm.
