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 (Application A.13-10-020). The Proposed Project has been reviewed under both the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). The CPUC approved the project in Decision D.16-08-017, including two alternatives, on August 18, 2016.

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. The BLM project website can be accessed here.

Project Construction and Status

The CPUC, BLM, and SCE are currently preparing a Mitigation Monitoring, Compliance, and Reporting Plan (MMCRP) to ensure compliance with the mitigation measures adopted in the Final EIR and Final EIS. When construction starts, information will be made available here.

Description of Approved Project

After reaching an agreement with the Morongo Band of Mission Indians, SCE filed this CPCN application for the West of Devers Upgrade Project with the CPUC and filed a Plan of Development with the BLM.

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 lines.

  • Removal and relocation of 4 miles of existing 12 kV distribution lines.

  • Installation of telecommunication lines and equipment for the protection, monitoring, and control of transmission lines and substation equipment.

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.

The Proposed Project is modified in several locations by two alternatives adopted by the CPUC: the Tower Relocation Alternative and the Iowa Street Underground Alternative.

Proponent's Environmental Assessment (PEA)

SCE filed an application and PEA for the WOD Project on October 25, 2013.

Since the SCE filing, the CPUC has conducted a 30-day completeness/deficiency review. Based on the review of the PEA, the CPUC sent deficiency letters to SCE on November 25, 2013, and February 18, 2014, indicating that the PEA remained incomplete. On September 11, 2014, the CPUC determined that the application and PEA were complete.

Environmental Review

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 EIR/EIS.

Data Requests. During the preparation of the EIR and EIS, the CPUC and BLM have identified information items needed for the EIR/EIS analysis and submitted data requests to SCE. In addition, after release of the Draft EIR/EIS, several data requests were submitted to the CPUC. Copies of each request and the responses are provided here.

Environmental Impact Report/Environmental Impact Statement (EIR/EIS)

Draft EIR/EIS. The Draft EIR/EIS was published August 7, 2015. The comment period closed on September 22, 2015. Comments submitted on the Draft EIR/EIS are available here.

Final EIR. The Final EIR for CEQA compliance was published by the CPUC on December 11, 2015. Comments that were submitted on the Draft EIR/EIS are presented in Volume 4 of this Final EIR, along with responses to all comments. The CPUC is expected to make a decision on the project in 2016.

Revised Phased Build Alternative Description. The CPUC has prepared a revised Phased Build Alternative description from the Alternatives Screening Report in Appendix 5 of the West of Devers Upgrade Project Final EIR that was distributed on December 11, 2015. This revised alternative description is based on additional information provided in the Opening Testimony submitted in January 2016 in the project's General Proceeding A.13-10-020, can be accessed here.

Addendum to Final EIR. On April 12, 2016, the CPUC released an Addendum to the West of Devers Upgrade Project Final EIR, which can be accessed here. The Addendum incorporates changes to Final EIR text and mitigation measures in response to additional information that was submitted by SCE in filings to the CPUC.

Final EIS. The Final EIS was published on August 12, 2016 and is available on the BLM project website, which can be accessed here.
