Welcome to the California Public Utilities Commission (CPUC) website for environmental review of Southern California Edison's (SCE's) Transmission Line Rating Remediation (TLRR) Eagle Mountain-Blythe 161 kV (kilovolt) Project (project). The Project is located entirely within the Chuckwalla Valley in Riverside County, California. The circuit extends approximately 53 miles (approximately 279,840 feet) and encompasses 581 acres from the Eagle Mountain Substation near Desert Center, California to the Blythe Substation in Blythe, California. The Project falls within the Victory Pass, East of Victory Pass, Corn Spring, Sidewinder Well, Aztec Mines, East of Aztec Mines, Hopkins Well, Roosevelt Mine, and Ripley 7.5-minute U.S. Geological Survey (USGS) topographic quadrangles.
