Bonneville Power Administration is proposing to replace the single pole structure 8/9 of the Benton-Scooteney No. 1 115-kilovolt (kV) transmission line, the attached vertically mounted disconnect switch, and current guy wiring with a new, 30-foot wide, three-pole transposition structure, a new horizontally mounted disconnect switch, and new guy wiring. In addition, a new 14-foot wide two-pole structure and a new 25?5-foot switch support structure would be installed roughly 30-feet ahead of the substation dead-end and approximately 15-feet ahead of the KD, respectively. There would be no disturbances to access roads. Under existing conditions the vertically mounted disconnect switch on the single pole is prone to sparking and consequently welding itself shut. In lieu of temporary fixes, this project would provide a permanent solution. In addition, the 3-pole replacement structure for tower 8/9 on the Benton-Scooteney No.1 115-kV transmission line would provide increased clearance above the neighboring orchard.
