Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of proposed construction of the Devers–Palo Verde No. 2 (DPV2) Transmission Line Project. An application for this project was submitted to the CPUC on April 11, 2005. The application was determined to be complete and in compliance with CPUC requirements on September 30, 2005. The CPUC approved the DPV2 Project on January 25, 2007 in Decision D.07-01-040 and certified the EIR as being in compliance with the requirements of CEQA.

On May 14, 2008, SCE filed a Petition for Modification (PFM) of the existing Certificate for Public Convenience and Necessity (CPCN) approved per Decision D.07-01-040. SCE requested that the CPUC authorize SCE to construct DPV2 facilities in only the California portion of DPV2 and the Midpoint 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.

This site provides access to public documents and information relevant to the CEQA review process.

Construction Progress and Mitigation Monitoring

Construction of the Devers-Palo Verde No. 2 Project is scheduled to begin in June 2011 with the establishment of some construction and helicopter yards. Notices to Proceed (NTPs) will be issued by the CPUC for each construction activity. The majority of construction is expected to start in Fall 2011 once the CPUC and each applicable agency (BLM and/or USFS) issues NTPs for the transmission line construction. Issuance of NTPs will be contingent upon SCE compliance with pre-construction requirements as specified by the approved mitigation measures and responsible agency permitting requirements. NTPs that have been issued to SCE are noted in the table below.

1 - Compliance with all remaining pre-construction mitigation measures and NTP conditions satisfied

The CPUC, in conjunction with SDG&E, BLM, USFS and other Responsible Agencies, drafted a Mitigation Monitoring Compliance and Reporting Program (MMCRP) to ensure compliance with mitigation measures approved in the Final EIR/EIS, as well as with the terms and conditions associated with the BLM right-of-way. Although changes may be made to the document as construction progresses, a current final version of the MMCRP document and attachments, including a map of the approved route, is found here.

A CPUC Environmental Monitor (EM) is monitoring construction activities to ensure that they are conducted in accordance with the approved mitigation measures and permit conditions. Weekly reports documenting construction status and compliance activities will be posted here when construction begins.

As defined by the MMCRP, at various times throughout project construction, the need for extra workspace or additional access roads may be identified. Similarly, changes to the project requirements (e.g., mitigation measures, specifications, etc.) may be needed to facilitate construction (e.g., nighttime construction in response to a planned power outage) or provide more effective protection of resources (e.g., installation of additional erosion control outside of approved disturbance areas). The CPUC Project Manager, along with the CPUC EMs, will implement the variance procedures defined in the MMCRP to evaluate each proposed project change for its potential for creating significant environmental effects to determine whether supplemental CEQA and/or NEPA review is required. Variance Requests processed to date are provided in the table below.

Project Refinements Report

The CPUC has published a Mitigation Consistency Determination Memorandum on SCE's proposed Project Refinements. After careful review of the proposed modifications, as documented in the Mitigation Consistency Determination Memorandum, the CPUC has determined that the changes to the DPV2 Project are within the scope of the Certificate of Public Convenience and Necessity issued by the CPUC.

Background: After the California-only project was approved by CPUC in November 2009, SCE began the process of completing final project design and engineering. As is common, some project components were modified as engineering was completed. Modifications result from compliance with adopted mitigation measures requiring resource avoidance to minimize or avoid environmental impacts and final engineering design requirements. In addition, project components may be relocated to accommodate landowner location preferences where possible in compliance with mitigation requirements.

Information regarding final project design was provided by SCE to the CPUC and BLM in two Project Refinements Reports, dated August 2010 and October 2010. In addition to the refinements outlined in the August 2010 and October 2010 Project Refinements Reports, SCE proposed two additional construction yards in April 2011.

The Project Refinements Reports define changes made to the project along the entire route after publication of the Final EIR/EIS, explain the reason for each change, and present the comparative environmental impacts of the project components analyzed in the Final EIR/EIS and those presented in the Project Refinements Reports. SCE's Project Refinements Reports are found here.

Focused Final Supplemental Environmental Impact Report – Released April 29, 2011

The Draft Supplemental EIR was released on February 22, 2011 and is available here. The comment period on the Draft Supplemental EIR closed on April 8, 2011. Twelve comment letters were received and are available here.

The Final Supplemental EIR was released on April 29, 2011 and is available here. The Final Supplemental EIR includes all comments and responses to comments that were submitted during the comment period on the Draft Supplemental EIR.

Background. After the CPUC's 2009 Decision regarding the PFM, several large solar power projects were proposed in the Blythe area. Two of these projects, the Blythe Solar Power Project and the Genesis Solar Energy Project, have requested interconnection to the electricity grid at the Desert Southwest–Midpoint Substation. As a result, the solar developers and SCE developed a plan to expand the Midpoint Substation, now known as the Colorado River Substation, to allow the required space for generation tie lines to be interconnected with the SCE 500 kV transmission system. SCE filed a Permit to Construct application addressing the substation expansion (A.10-11-005). This expansion was not covered in the original EIR/EIS because the solar power projects had not yet been proposed.

During 2009 to 2010, the Blythe Solar Power Project and the Genesis Solar Energy Project have been evaluated under CEQA and NEPA by the BLM and the California Energy Commission. The environmental review documents addressed the Colorado River Substation expansion but they did not adequately cover all issues that the CPUC requires to be addressed in accordance with CEQA. Therefore, the CPUC prepared a Focused Supplemental EIR to address only the specific issues not yet covered for its purposes by the previous environmental review.

A Notice of Preparation (NOP) was sent to interested agencies and members of the public in October 2010 and can be accessed here. The CPUC held a 30-day scoping period soliciting information regarding the topics that should be included in the Focused Supplemental EIR for the Colorado River Substation expansion. Copies of all letters received and a summary of the scoping process and scoping comments are included in a Scoping Report (December 2010), which can be accessed here.

All documents filed as part of the CPUC’s proceeding (A.10-11-005) can be accessed here.

Draft and Final Environmental Impact Report/Environmental Impact Statement

The CPUC and BLM released the Draft Environmental Impact Report/Environmental Impact Statement (Draft EIR/EIS) for the proposed project on May 4, 2006.

The submittal period for public comments on the Draft EIR/EIS was extended from July 5, 2006 to August 11, 2006.

The Final Environmental Impact Report/Environmental Impact Statement (Final EIR/EIS) was issued on October 24, 2006. The Final EIR/EIS consists of three volumes. Volumes I and II are completely re-printed from the Draft EIR/EIS. Changes made to the Draft EIR/EIS are marked in Volumes I and II: inserted text is underlined and deleted text is shown in strikeout. Volume III consists of all comments in the Draft EIR/EIS and responses to comments.

Over 475 pages of comments on the Draft EIR/EIS were submitted to the BLM and the CPUC, including transcripts from the July 2006 Public Participation Hearings.
