¹BAT certification for all 2003 year model snowmobiles will expire at the end of the 2008-09 winter.
Notes
- Once approved, a snowmobile would generally be certified in Yellowstone as BAT for a period of six years. On Jackson Lake in Grand Teton, a snowmobile would be certified as BAT for six years or 6,000 miles, whichever is greater, not to exceed 10 years regardless of mileage.
- Air emission figures presented are either the Official Test Results (OTR) or the certified FEL. The Official Test Results are actual measured emissions. The FEL’s are not-to-exceed levels as certified by EPA.
- Sound emission figures represent an average of Official Test Results.
- 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.
* 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.)
** Hydrocarbons: certified by EPA to a Family Emissions Limit (FEL) of 15 g/kW-hr or less.
** Carbon Monoxide: certified by EPA to a Family Emissions Limit (FEL) of 120 g/kW-hr or less.

Did You Know?
Some groups of Shoshone Indians, who adapted to a mountain existence, chose not to acquire the horse. These included the Sheep Eaters, or Tukudika, who used dogs to transport food, hides, and other provisions. The Sheep Eaters lived in many locations in Yellowstone.
