Bonneville Power Administration (BPA) proposes to install about 1.5 miles of aerial fiber optic cable on the existing Midway-Rocky Ford No.1 230-kilovolt (kV) transmission line. The new fiber optic cable would replace the overhead groundwire (OHGW) on the Midway-Rocky Ford No.1 transmission towers. The fiber would span from a tower in the Midway Substation yard to tower 1/1 (first mile/first tower) on the Midway-Rocky Ford line, where a new fiber splice enclosure box would be installed on the tower. The fiber would then continue to replace the existing OHGW and span to tower 2/1 on the north side of the Columba River, where another splice enclosure would be installed on the tower. From tower 2/1, the fiber would jump to tower 1/6 on the Midway-Vantage 230-kV line, where it would run down the tower leg and be spliced within an existing vault, completing the redundant path.
