The comment period on plans by Yellowstone National Park to extend the so-called “one year rule” regarding the management of snowmobiles and snowcoaches in the park for the upcoming 2012-2013 winter season has begun. This proposal would implement the same rules as have been in place for the past three winters. This plan allows for up to 318 commercially guided Best Available Technology snowmobiles and up to 78 commercially guided snowcoaches daily. It will also continue to provide access for motorized oversnow travel over the East Entrance road and Sylvan Pass. The proposed rule that would implement this action was published in the Federal Register yesterday, and is available for public review and comment for 30 days.
