Welcome to the California Public Utilities Commission (CPUC) website
for the environmental review of the proposed Southern California
Edison (SCE) West of Devers Upgrade Project (Proposed Project).
The project is proposed to be located in incorporated and unincorporated
portions of Riverside and San Bernardino Counties, California; a
map is provided here. SCE
submitted a Certificate for Public Convenience and Necessity (CPCN)
application for the Project to the CPUC on October 25, 2013
A.13-10-020). The Proposed Project is subject to review under
both the California Environmental Quality Act (CEQA) and the National
Environmental Policy Act (NEPA).
The CPUC is the CEQA lead agency and the Bureau of Land Management
(BLM) is the NEPA lead agency. This site provides access to public
documents and information relevant to the CEQA review processes.

Description of Proposed Project
Previously Proposed West of Devers Upgrades. On April 11,
2005, SCE submitted an application for a CPCN for a 500 kV interstate
transmission line project, the Devers-Palo Verde No. 2 (DPV2).
The project included three major components:
- A 500 kV line from the Palo Verde area in Arizona to a new substation
near Blythe, California;
- A 500 kV line from the Blythe area substation to the Devers
- Upgrades to SCE's lower voltage transmission system west of
the Devers Substation.
The CPUC approved the DPV2 Project in January 2007 in Decision
D.07-01-040. The approved Project included the SCE proposal except
for the West of Devers Upgrades, which were replaced by the Devers
to Valley 500 kV #2 line. On May 14, 2008, SCE filed
a Petition for Modification (PFM) of the CPCN approved per Decision
D.07-01-040. In the PFM, SCE requested that the CPUC authorize SCE
to construct DPV2 facilities in only the California portion of DPV2
and the Midpoint Substation (later re-named as the Colorado River
Substation) near Blythe, California. The CPUC approved SCE's PFM
on November 20, 2009 in Decision D.09-11-007. The BLM issued
its Record of Decision approving the project on July 19, 2011.
The West of Devers upgrade components as proposed by SCE in 2005
could not be approved by the CPUC and BLM because by the time of
agency decisions (January 2007), the Morongo Band of Mission Indians
had not reached an agreement with SCE on terms of the right-of-way
(ROW) renewal for the nearly 6 miles of the corridor that crosses
tribal land. Therefore, the Devers Substation to Valley Substation
alternative route was approved instead of the WOD Project route,
and that segment has now been constructed. In addition, the 500
kV segment from the new Colorado River Substation (southwest of
Blythe) to the Devers Substation has been constructed.
New West of Devers Upgrade Project. In 2013, SCE and the
Morongo Band reached an agreement on the terms for ROW renewal for
the corridor on Morongo tribal land. After reaching this agreement,
SCE filed this CPCN application for the West of Devers Upgrade Project
with the CPUC and filed a Plan of Development with the BLM. The
CPUC and BLM will prepare a joint environmental impact report (EIR)
and Environmental Impact Statement (EIS) to comply with both CEQA
According to SCE the Proposed Project would be needed to facilitate
the full deliverability of new electric generation resources being
developed in eastern Riverside County. As renewable energy generating
facilities come on-line in eastern Riverside County, the West of
Devers Upgrade Project would allow the transfer of this electricity
into the Los Angeles area. The Proposed Project would facilitate
progress towards meeting California's Renewable Portfolio Standard
goals requiring utilities to produce 33% of their electricity sales
from renewable energy sources by 2020.
The West of Devers Upgrade Project as proposed by SCE includes
the following major components:
- Removal and upgrade of existing 220 kV transmission lines. Upgrades
would occur on 30 miles of the Devers-El Casco line, 14 miles
of the El Casco-San Bernardino line, 43 miles of the Devers-San
Bernardino line, 45 miles of the Devers-Vista No. 1 and No. 2
lines, 3.5 miles of the Etiwanda-San Bernardino line, and 3.5
miles of the San Bernardino-Vista line.
- Upgrade substation equipment at Devers, El Casco, Etiwanda,
San Bernardino, and Vista Substations to accommodate increased
power transfer on 220 kV lines.
- Upgrade Timoteo and Tennessee 66/12 kV substations to accommodate
66 kV subtransmission line relocations.
- Removal and relocation of 2 miles of two existing 66 kV subtransmission
- Removal and relocation of 4 miles of existing 12 kV distribution
- Installation of telecommunication lines and equipment for the
protection, monitoring, and control of transmission lines and
The Proposed Project would be located within the existing West
of Devers right-of way corridor in incorporated and unincorporated
areas of Riverside and San Bernardino Counties. The ROW passes through
the reservation trust land of the Morongo Band of Mission Indians
and the cities of Banning, Beaumont, Calimesa, Colton, Grand Terrace,
Loma Linda, Palm Springs, Rancho Cucamonga, Redlands, San Bernardino,
and Yucaipa (see project map).
SCE states that the Proposed Project would be operational by 2020.
Proponent's Environmental Assessment
SCE filed an application
and PEA for the WOD Project on October 25,
Since the SCE filing, the CPUC has conducted a 30-day completeness/deficiency
review. Based on the review of the PEA, the CPUC sent a deficiency
letter to SCE on November 25, 2013 indicating that the
PEA is incomplete. SCE is working with the CPUC to satisfy all the
Notice of Preparation (NOP) and Notice of Intent (NOI).
Issuance of a CEQA Notice of Preparation (NOP)
and NEPA Notice of Intent (NOI)
is the first step in the EIR/EIS process. These documents provide
a description of the proposed Project and potential alternatives,
as well as a schedule of the CPUC and BLM's proposed scoping process
that will include public scoping meetings and agency consultations.
The NOP was published on May 7, 2014. The NOI was published
on July 1, 2014.
Scoping Meetings. In order for the public and regulatory
agencies to have an opportunity to ask questions on the scope of
the EIR/EIS, the CPUC held 4 scoping meetings in the project area
on May 19, 20, and 21, 2014, and the BLM held one scoping meeting
on July 16, 2014. Information presented at the meetings, and
meeting transcripts, are available here.
Public Scoping Report. The CPUC and BLM have prepared Public
Scoping Reports that document the scoping activities and oral
comments from the scoping meetings, as well as the written documents
submitted in response to the NOP and NOI. These reports will serve
as information sources to the CPUC and BLM in their determination
of the range of issues and alternatives to be addressed in the Draft
Data Requests. The CPUC and BLM have identified information
items needed for the EIR/EIS analysis and have submitted the following
data requests. Responses to these data requests will be posted here,
as they are received. Additional data requests will be included,
as they are needed throughout the environmental review process.
