Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of the proposed construction of the San Diego Gas & Electric (SDG&E) South Bay Substation Relocation Project (Proposed Project) located in the City of Chula Vista, California, in the southwesterly portion of San Diego County, California. SDG&E submitted an application to the CPUC on June 16, 2010 (Application A.10-06-007). The Proposed Project is subject to review under the California Environmental Quality Act (CEQA). This site provides access to public documents and information relevant to the CEQA review processes. BackgroundSDG&E filed an application for a Permit to Construct the South Bay Substation Relocation Project with CPUC. The CPUC, as lead agency under California law, will prepare an environmental impact report (EIR) to comply with CEQA. The South Bay Substation Relocation Project, as proposed by SDG&E, includes the following major components:
The Proposed Project would be located in the City of Chula Vista, California, in the southwesterly portion of San Diego County (see Regional Map). The Proposed Project primarily involves relocation of the existing South Bay Substation to a new site approximately 0.5 mile south. The existing South Bay Substation would be relocated to the proposed Bay Boulevard Substation site, which is situated approximately 2 miles south of the City of National City, approximately 5 miles northeast of the City of Imperial Beach, and approximately 7 miles southeast of downtown San Diego (see Project Location Map). The South Bay Substation is an aging 138/69 kV substation that was originally built to accommodate the adjacent South Bay Power Plant (SBPP) in the City of Chula Vista. The South Bay Substation was originally constructed in 1961 and consists of equipment that was not built to modern seismic standards. The existing 138 kV bus is undersized for current transmission system conditions. The 69 kV bus is also configured in such a way that overloads of the 69 kV transmission line occur in the South Bay region caused by 69 kV bus outages at the South Bay Substation. With the potential retirement of the SBPP, a replacement bulk power source is being proposed to connect to the existing 230 kV transmission lines in the area (Otay Metro Power Loop (OMPL) Project (formerly referred to as the Otay Mesa Power Purchase Agreement Project)). In October 2004, SDG&E and the City of Chula Vista entered into a Memorandum of Understanding (MOU) regarding several energy issues (see MOU). One of the objectives of the City of Chula Vista in the MOU was the relocation of the existing South Bay Substation after the retirement of the SBPP. SDG&E’s projected schedule is to have the Bay Boulevard Substation energized and transmission line connections completed, so that decommissioning and demolition of the existing South Bay Substation can occur after the potential retirement of the SBPP. Public Scoping Meeting for an Environmental Impact Report (EIR)Public Scoping MeetingThe purpose of this public scoping meeting was to present information about the Proposed Project and the CPUC's decision-making process, and to listen to public views on the range of issues relevant to preparation of the draft EIR. At the public meeting, the environmental team and CPUC staff were available to respond to questions and discuss the environmental document that is under preparation. The meeting was held at the Chula Vista Civic Center Council Chambers, 430 F Street, on Monday, August 1, 2011, from 6:00 p.m. to 8:00 p.m. The public informational meeting presentation is available here. Other Documents AvailableNotice of Preparation (NOP) Notice was given that the CPUC, as lead agency under CEQA, will prepare an EIR for the Proposed Project. Notice for the public scoping meeting was published in the San Diego Union-Tribune on July 13, 2011, and was also made available to the public on this website. The NOP was sent to 21 federal agencies, 43 state agencies, and 118 local agency contacts and planning groups. The NOP was also distributed to 130 private organizations and individuals, 19 Native American groups, and 6 local libraries. The Notice of Preparation is available for review here. Public Report The Public Scoping Report describes scoping activities and documents the written comments received regarding the CPUC's NOP. This report serves as an information source to the CPUC in its determination of the range of issues and alternatives to be addressed in the Proposed Project. The comment period for the NOP ended on August 15, 2011. In total, 16 letters were received. These comments are incorporated into the EIR project record, and they are documented and summarized in this Scoping Report. The Public Scoping Report is available for review here.
