South Dakota consumers choosing to fill up with biodiesel will great a break on their gas bill.

This story in the Rapid City (SD) Journal says Gov. Mike Rounds has signed into law a measure that will give a 2-cent per gallon tax break for every gallon of diesel sold with 5 percent biodiesel:

“As diesel costs continue to skyrocket, this tax break will help ease the pain at the pump for consumers while helping to develop our state’s biodiesel industry,” Rounds said in a news release. “Biodiesel is an ideal alternative to petroleum-based fuel. It will not reduce mileage, and because of its increased lubricity, it is better for the engine.”

This incentive is a little different than other states’ programs that don’t kick in until there’s a minimum of alternative fuel available. This one will end when 35 million gallons of taxed biodiesel and biodiesel blended fuel are sold after the effective date.
