Proposed Location: Southern California Edison (SCE) is proposing to upgrade and remove the following existing 220 kV transmission lines within SCE’s existing West of Devers (WOD) right-of way corridor in incorporated and unincorporated areas of Riverside and San Bernardino Counties: Devers-El Casco (30 miles), El Casco-San Bernardino (14 miles), Devers-San Bernardino (43 miles), Devers-Vista No. 1 and No. 2 (45 miles), Etiwanda-San Bernardino (3.5 miles), and San Bernardino-Vista (3.5 miles).
Of the overall 45-mile length of the transmission corridor, approximately 1 mile of the corridor is proposed on BLM-administered public lands and approximately 6 miles would cross the reservation Trust Lands (reservation) of the Morongo Band of Mission Indians. The BLM lands are located east of the City of Banning and west of the City of Desert Hot Springs in Riverside County. The project would be within a designated utility corridor and within an existing ROW and would not require a plan amendment to the CDCA plan.
In addition to the transmission line improvements, additional infrastructure upgrades would be needed. Substation equipment at Devers, El Casco, Etiwanda, San Bernardino, Timoteo and Tennessee and Vista Substations would be upgraded to accommodate the project changes to transmission and subtransmission systems. Subtransmission upgrades would include removal and relocation of 2 miles of existing 66 kV lines and upgrades at Timoteo and Tennessee 66/12 kV Substations to accommodate the relocated 66 kV line. Electric distribution line upgrades would include removal and relocation of 4 miles of existing 12 kV lines. The project would also install telecommunication lines and equipment for the protection, monitoring, and control of transmission lines and substation equipment.
Technology: Combination of 220/66/12 kV energy transmission lines and 7 substations. The project would cross BLM and BIA administered public lands, tribal lands and private lands.
Company: Southern California Edison
Status: The Final EIS is available for public review with a 30-day comment period starting 8/5/2016.
