Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of the San Diego Gas & Electric (SDG&E) Salt Creek Substation Project located in southwestern San Diego County, California. SDG&E submitted an application to the CPUC on September 25, 2013 (Application A.13-09-014). The project was subject to review under the California Environmental Quality Act (CEQA) and the CPUC is the CEQA Lead Agency. A CEQA review was performed to evaluate the potential environmental impacts associated with this project. This site provides access to public documents and information relevant to the CEQA environmental review processes. All phases of the project have been completed as of June 2018, and the substation is currently in service. QUICK LINKSApplication and Proponent's Environmental Assessment (PEA) Project ScheduleConstruction of the Salt Creek Substation Project (project) began on July 18, 2016, and the site development phase of the project was completed on April 5, 2017. All phases of the project have been completed as of June 2018.
Commission DecisionThe Commission voted on May 12, 2016, to grant SDG&E a permit to construct Alternative 2, the environmentally superior alternative (Salt Creek Substation with Generation at Border and Larkspur Generation Facilities). Alternative 2 includes the following elements:
The Notice of Determination (NOD) was filed with the State Clearinghouse on May 23, 2016. The Commission decision can be viewed here. The NOD can be viewed here. Project ConstructionMitigation MonitoringA Mitigation Monitoring, Compliance, and Reporting Plan (MMCRP) was prepared to ensure compliance with applicant proposed measures (APMs) and mitigation measures (MMs) approved in the Final EIR. This MMCRP was developed to provide guidelines and standardize procedures for environmental compliance during project implementation. The procedures were developed in coordination with SDG&E and CPUC and define the reporting relationships, the roles and responsibilities of the project's environmental compliance team members, compliance reporting procedures, and the communication protocol.The MMCRP can be viewed here (2.5 MB). The Post-Construction Monitoring Report was prepared to fulfill the reporting requirements described in the MMCRP (Section 2.5.8 Reporting). This report summarizes implementation of project APMs and MMs during site development, the success of the overall monitoring effort, and the APM and MM compliance requirements following construction. The Post-Construction Monitoring Report is available below: Post-Construction Monitoring Report Appendix A - Applicant Proposed Measure and Mitigation Measure Verification Tables Appendix B - Mitigation Monitoring, Compliance, and Reporting Program Requests and Authorizations (8 MB) Appendix C - Permits and Approvals (14.5 MB) Appendix D - CPUC Monitoring Summary Reports (53 MB) Appendix E - Compliance Documentation (32 MB) Notice to ProceedThe Notice to Proceed (NTP) was issued to SDG&E by the CPUC on June 21, 2016. The NTP can be viewed here (2.6 MB).Monthly Monitoring ReportsCPUC Environmental Monitors monitor construction activities to ensure that they were conducted in accordance with approved mitigation measures and permit conditions. Monthly reports documenting construction activities and compliance can be viewed here. Minor Project Refinements

| MPR 7 | Construct a 50-foot concrete section of the lower transmission corridor road with attached brow ditch and 25-foot concrete spillway above the catch basin, and place 5 tons of 6-inch rock in the rill between the upper and lower transmission corridor roads to reduce stormwater velocity and minimize soil erosion |
| MPR 8 | Create additional temporary work spaces for irrigation installation and revisions to the container plant palette, which was included in the approved Landscape Plan |
SDG&E filed an application for a Permit to Construct the Salt Creek Substation Project with the CPUC. SDG&E proposed the following components:
The project is located in the City of Chula Vista.
On September 25, 2013, SDG&E submitted an Application for a Permit to Construct, including a proponent's environmental assessment (PEA) for the Salt Creek Substation Project. The PEA was a starting point for the independent environmental review process conducted by the CPUC.
SDG&E's Application and PEA were deemed complete by the CPUC on May 19, 2014.
The CPUC Environmental Review Team submitted data requests to the applicant for specific information to support the environmental review process. Those requests and the applicant's responses can be viewed here.
Issuance of a CEQA Notice of Preparation (NOP) is the first step in the EIR Process. This document provides a description of the proposed project and potential alternatives, as well as information regarding the scoping process. The NOP was published on August 15, 2014. Click here to view the NOP.
The CPUC prepared a Draft Environmental Impact Report (EIR) in compliance with CEQA. The Notice of Availability and the Draft EIR are available to view below.
A public meeting to accept comments on the Draft EIR was held on June 4, 2015. The meeting transcript and presentation that was presented at the meeting is available below.
The 45-day public comment period on the Draft EIR ended on June 29, 2015. Comments received on the Draft EIR are available below.
The CPUC prepared a Final Environmental Impact Report (EIR) in compliance with CEQA. The Final EIR is available to view below.
