Special Regulations; Areas of the National Park System, Yellowstone National Park

概要

This rule implements the Record of Decision for the 2011 Winter Use Plan/Environmental Impact Statement and governs winter visitation and certain recreational activities in Yellowstone National Park for the 2011-2012 winter season. The rule retains, for one additional year, the regulations and management framework that have been in place for the past two winter seasons (2009-2010 and 2010- 2011). Specifically, the rule retains provisions that: require most recreational snowmobiles operating in the park to meet certain National Park Service air and sound emissions requirements; require snowmobiles and snowcoaches in Yellowstone to be accompanied by a commercial guide; set daily entry limits on the numbers of snowmobiles (up to 318) and snowcoaches (up to 78) that may enter the park; and prohibit traveling off designated oversnow routes.
