Border States Cooperative has opened Minnesota’s first ethanol “blender pumps” in Ortonville, near the South Dakota border.

The blender pumps allow motorists to choose several different blends of ethanol from the legally mandated 10 percent up to 85 percent.

Border States Cooperative officials say they put the blender pumps in last year for E85 but were unable to use them to their full capability until the state’s rules changed. Border States Cooperative put the pumps into operation last week and held grand opening ceremonies on Tuesday.

The blender pumps are already being used in South Dakota.
