Headgate Rock-Blythe No. 1, 161-kV Transmission Line Structure Replacement and Black Point Mesa Reroute, CA, DOE/EA-1427

Western owns and operates the Parker-Blythe No. 1 161-kV transmission line between Parker Dam and Blythe Substation, in Blythe, Calif.

The transmission line is almost 50 years old, and the wood poles are beginning to age and show signs of failure. Western wants to replace H-frame wood poles and five specialized structures with H-frame, light-duty steel structures from Headgate Rock Substation to Blythe Substation. Replacing the structures on the transmission line will require an additional temporary right of way of 100 feet around each pole.

Another proposed reroute would move the existing line from a sensitive cultural site in LaPaz County, Ariz. to a new location in San Bernardino and Riverside counties in California.
