Williston, N.D. (AP) Construction on a 200-mile-long power line in western North Dakota is set to begin after getting the go ahead from two federal agencies. Basin Electric says the U.S. Forest Service and the Rural Utilities Service gave approval for the project recently. The company is still waiting for approval from the U.S. Army Corps Of Engineers and the Western Area Power Administration but the company says construction can begin now. The 345-kilovolt transmission line from basin electric's power station near Beulah to the oil patch town of Tioga was approved by state regulators in April. The project faced opposition from American Indian Tribes as it crosses through Killdeer Mountain battlefield. Federal troops fought Sioux Warriors there in 1864. The tribes were fearful that the line could disturb remains of those killed.
