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

الملخص

This rule would implement an amended Record of Decision for the 2011 Winter Use Plan/Environmental Impact Statement and would govern winter visitation and certain recreational activities in Yellowstone National Park for the 2012-2013 winter season. The rule proposes to retain, for one additional year, the regulation and management framework that have been in place for the past three winter seasons (2009-2010, 2010-2011 and 2011-2012). Specifically, the rule would retain 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.
