PIERRE, S.D. — The South Dakota Public Utilities Commission voted 2-1 Monday to approve the Bakken crude oil pipeline, but added conditions to better protect landowners along the route.“It is crucial that we do this right so that our farmers and ranchers can get back to doing what they do best, producing food for the world,” Chairman Chris Nelson said.The 1,134 mile pipeline proposed by Energy Transfer Partners of Texas would carry Bakken crude from North Dakota to Patoka, Ill, crossing 18 Iowa counties.
