EA-1617: Draft Environmental Assessment

Lovell-Yellowtail and Basin-Lovell Transmission Line Rebuild Project

Western Area Power Administration, Rocky Mountain Customer Service Region (Western) proposes to rebuild the Lovell-Yellowtail (LV-YT) No. 1 and No. 2 115-kilovolt (kV) transmission lines, located in Big Horn County, Wyoming and Big Horn and Carbon Counties in Montana and the Basin-Lovell (BA-LV) 115-kV transmission line in Big Horn County, Wyoming. The LV-YT No. 1 and 2 transmission lines parallel each other and are approximately 47 miles in length with termination points at the Yellowtail Substation near Fort Smith, Montana and the Lovell Substation near Lovell, Wyoming. The BA-LV transmission line is approximately 39 miles in length with termination points at the Basin Substation near Basin, Wyoming and the Lovell Substation. The Nahne Jensen Substation is connected to the BA-LV transmission line near Greybull, WY. The rebuilt lines would be upgraded with a larger conductor and would continue to operate at 115 kV.
