Document Description
A transmission line upgrade project to improve the reliability and safety of the 230-kV KN/KS transmission line, which extends through federal and non-federal lands between the Midway Substation located near Niland, California, and the Coachella Valley Substation in Coachella, California. The upgrade project would affect portions of the existing transmission line, which contains both lattice towers and tubular steel poles constructed in the late 1980's. Stability problems experienced during high winds indicated a need to upgrade the existing structures. The lattice towers and seven of the tubular steel poles were upgraded in the late 1990s, however the remaining tubular steel poles were not upgraded at that time. With the proposed project, 41 of the existing steel poles would either be replaced with a single new steel pole or upgraded to two-pole structures.
