1 EPA Family Emissions Limits (FEL) for Snowmobiles are 75 for Hydrocarbons and 275 for Carbon Monoxide (2010 and 2011 model years). (See Federal RegisterVol. 73, No. 123, Wednesday, June 25, 2008, page 35946)
2 Hydrocarbons: certified by EPA to a Family Emissions Limit (FEL) of 15 g/kW-hr or less.
3 Carbon Monoxide: certified by EPA to a Family Emissions Limit (FEL) of 120 g/kW-hr or less. Air emission figures for carbon monoxide and hydrocarbons presented are either the Official Test Results (OTR) or the certified FEL. The Official Test Results are actual measured emissions. FEL's are not-to-exceed levels as certified by EPA.
4  Society of Automotive Engineers testing procedures allow for a 2 dB tolerance over the sound level limit to provide for variations in test site, temperature gradients, wind velocity gradients, test equipment, and inherent differences in nominally identical vehicles. (It has been observed that under some test site conditions, variability in test results greater than 2 dB can be experienced.) Sound emission figures represent an average of Official Test Results.
5 YellowstoneBAT certification for all 2007 year model snowmobiles will expire at the end of the 2011-2012 winter. Once approved, a snowmobile would generally be certified in Yellowstone as BAT for a period of six years.
6 The 2004 Bombardier Ski-Doo Elite SE and the 2003-2005 Legend Sport GT V1000 must be equipped with BAT upgrade kits in order to meet BAT requirements. The upgrade kits lowers emissions levels by controlling the maximum throttle body opening and uses different software for the snowmobile's electronic control unit.

2003-2006 Model Year BAT Snowmobiles Authorized to be used on Jackson Lake in Grand Teton National Park

In Grand Teton National Park, BAT snowmobiles are allowed to be used on Jackson Lake for the purpose of ice fishing. The certification period is for six years, except that for individual machines, the period may be extended up to a total of 10 years provided that the mileage does not exceed 6,000 miles. Following are model year 2002-2004 snowmobiles authorized for use on Jackson Lake.

Upper Geyser Basin Hydrothermal Features on a Winter Day.

Did You Know?
Yellowstone contains approximately one-half of the world’s hydrothermal features. There are over 10,000 hydrothermal features, including over 300 geysers, in the park.
