SD increases ethanol usage in state vehicles

By | November 11, 2009
South Dakota plans to increase ethanol use in the state's fleet by installing ethanol fuel tanks at three Department of Transportation regional yards. Although nearly 40 percent of the state's 3,395 government vehicles are flexible fuel vehicles, E85 has only been available at commercial retail stations.

The addition of the tanks at the Rapid City, Pierre and Sioux Falls DOT regional yards is expected to increase E85 utilization from 32,640 gallons per year to approximately 250,000 gallons per year.
The fuel tanks will also dispense midlevel ethanol blends. For the first six months of operation, the tanks will dispense E85. For the next six months, the tanks will dispense a midlevel blend, likely E30. South Dakota's Fleet and Travel Office will monitor the use of ethanol-blended fuels and their performance. At the end of the year, the most efficient blend of ethanol will be the fuel routinely distributed at the DOT regional yards.
