STATE OF CALIFORNIA PUBLIC UTILITIES COMMISSION Southern California Edison's Valley South 115 kV Subtransmission Project (Application A.14-12-013 filed December 15, 2014)

Welcome to the California Public Utilities Commission (CPUC) website for SCE's Valley South 115 kV Subtransmission Project (Valley South). This website will provide information on the status of the CPUC's environmental review of the project under the California Environmental Quality Act (CEQA). SCE submitted an application for a Permit to Construct Electrical Facilities with Voltages between 50 kV and 200 kV to the CPUC on December 15, 2014. Concurrently, SCE also filed its Proponent's Environmental Assessment (PEA) for the project on this date. Based on a review of the application materials and responses to data requests, the CPUC determined that the application was complete in April 2015, which began the environmental review process under CEQA for Valley South.

Public Scoping Period

The CPUC recently released a Notice of Preparation announcing the preparation of an Environmental Impact Report (EIR) and the start of a 30-day public scoping period. The EIR public scoping period ends on June 8, 2015.

The CPUC invites written comments on the scope of the environmental analysis and identification of potential environmental issues related to the EIR. To submit written comments or to be added to the Project mailing list, please write to: Valley South Subtansmission Project Scoping Comments c/o Aspen Environmental Group, 5020 Chesebro Road, Suite 200, Agoura Hills, CA 91301.

E-mail communication are also welcome; however, please remember to include your name and a return address in the e-mail message. E-mail messages should be sent to Valley-South-Project@aspeneg.com. Written comments may also be submitted by fax at the phone number noted below. All written comment letters are requested by June 8, 2015.

Although no public scoping meeting is planned for this project, there will be future public meetings on the project when the public draft EIR is published and possibly through the application review process conducted by the CPUC Administrative Law Judge.

Background

The Valley South project is proposed to be located in southwestern Riverside County. The documents noted above provide more detail regarding the proposed location and key components of the project. A summary of the proposed project is provided below:

• Modification of SCE's existing Valley 500/115 kV Substation would include equipping an existing 115 kV line position and providing protection equipment as required.
• Construction of a new 115 kV subtransmission line originating at SCE's existing Valley 500/115 kV Substation and connecting at a Tubular Steel Pole (TSP), which is located at the southeast corner of Leon Road and Benton Road. The TSP is the common point of the three-terminal existing Valley-Auld-Triton 115 kV Subtransmission Line. The new construction and associated reconfiguration would result in the formation of the Valley-Auld No. 2 and Valley-Triton 115 kV Subtransmission Lines. The new 115 kV subtransmission line would be approximately 12 miles in length and is referred to as Segment 1 of the Proposed Project.
• Replacement of a segment of overhead conductor of the existing Valley-Auld-Triton 115 kV Subtransmission Line beginning at the TSP located at the southeast corner of Benton Road and Leon Road continuing south to the Terminal TSP located on the south side of Nicolas Road, approximately 250 feet west of Los Chorus Ranch Road in the City of Temecula. This reconductor segment is approximately 3.4 miles in length and is referred to as Segment 2 for the Proposed Project.
• Relocation of existing distribution and telecommunication lines would be required to support the installation of Segments 1 and 2 for the new 115 kV subtransmission line.
• Installation of telecommunication equipment at Triton and Valley Substations would support Segments 1 and 2 for the new 115 kV subtransmission line.
