Background Information


In 2005, SCE initiated the Moorpark-Newbury 66 kV Subtransmission Line Project to address forecasted overloads on a section of the existing line and to enhance reliability and operational flexibility. The project is located in Ventura County generally between State Route 118 (Los Angeles Avenue) to the north, Highway 101 to the south, and west of State Route 23, in the City of Moorpark, City of Thousand Oaks, and in portions of unincorporated Ventura County between the two cities. The subtransmission line would extend between SCE's Moorpark Substation and Newbury Substation within a portion of SCE's existing Moorpark-Ormond Beach 220 kV Transmission Line right-of-way (ROW) and within a portion of SCE’s existing Moorpark-Newbury-Pharmacy 66 kV Subtransmission Line ROW.

In February 2009, the CPUC issued Executive Director’s Action Resolution E-4225, finding that SCE's Moorpark-Newbury 66 kV Subtransmission Line Project qualified for an exemption and did not have to go through a CEQA review. Construction of the project began in 2010. However, in April 2010, several individuals filed an Application for a Rehearing and in November 2011, all construction activity was halted due to issuance of CPUC Decision 11-11-019. This decision ordered SCE to cease construction activity, provide certain specified information, and to file a Permit to Construct application in order to proceed with completing construction of the project. In response to Decision 11-11-019, SCE submitted a Permit to Construct and PEA to proceed with completion of the project. SCE anticipates that future proposed construction activities of the project would take approximately 10 months to complete upon CPUC approval.

Environmental Review

The CPUC has determined that it will prepare an Environmental Impact Report (EIR) to evaluate SCE's proposal to complete the project, as well as to evaluate a range of alternative to the project. The table below lists the anticipated dates for milestones that are/will be associated with the review of the project.

Public Scoping & Notice of Preparation of an Environmental Impact Report

On March 26, 2014, the CPUC published a Notice of Preparation (NOP) of an EIR for the Moorpark-Newbury 66 kV Subtransmission Line Project (A.13-10-021). A Notice of Completion (NOC) of the NOP was submitted to the State Clearinghouse on the same date. In order for the public and regulatory agencies to have an opportunity to submit comments on the scope of the EIR, an educational workshop and scoping meeting was held at 6:30 p.m. on Thursday April 10, 2014 at Santa Rosa Technology Magnet School, located at 13282 Santa Rosa Road in Camarillo. The slides presented at the workshop can be viewed here.

The public scoping period ended at 5:00 p.m. on April 25, 2014. A summary of the scoping process and comments received during the scoping period is included in the Scoping Report and associated appendices, which are available from the links below:

Environmental Impact Report

The CPUC is currently preparing the Draft EIR, which is anticipated to be released for public review during the first quarter of 2015. The Draft EIR will be presented here, when available. This website will also list the locations where hard copies of the Draft EIR will be available for review.
