Introduction

Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of the proposed construction of the San Diego Natural Gas Pipeline (Line 3602).

On September 30, 2015, San Diego Gas & Electric Company (SDG&E) and Southern California Gas Company (SoCalGas) (the applicants or proponents) requested a Certificate of Public Convenience and Necessity (CPCN) (Application No. A.15-09-013) from the CPUC to construct, operate, and maintain the Pipeline Safety and Reliability Project – New Natural Gas Line 3602 and De-rating Line 1600 (PSRP, or the proposed project). The CPUC regulates investor-owned public utilities in California and therefore is the agency responsible for reviewing the applicants’ CPCN application.

The CPCN application included the Proponent’s Environmental Assessment (PEA) which described the proposed project’s environmental impacts along with applicant proposed mitigation measures and alternatives to the proposed project. As part of the CPUC’s consideration of the CPCN application for the proposed project, the CPUC is conducting a review process that consists of (1) an environmental review under CEQA and (2) a project need and cost review proceeding.

The applicants propose to construct a new 36-inch natural gas pipeline (Line 3602) that would carry natural gas from SDG&E’s existing Rainbow Metering Station in Rainbow, California to land within Marine Corps Air Station (MCAS) Miramar. The proposed project also includes de-rating, or lowering the pressure of, SDG&E's existing Line 1600 to convert its function from transmission to distribution.

The applicants’ primary purpose for the proposed project is to construct a new natural gas transmission pipeline and associated facilities that will advance three fundamental objectives for the integrated SDG&E and SoCalGas natural gas transmission system in San Diego County:

  1. Implement the pipeline safety requirements for the existing Line 1600 and modernize the system with state-of-the-art materials;
  2. Improve system reliability and resiliency by minimizing dependence on a single pipeline; and
  3. Enhance operational flexibility to manage stress conditions by increasing system capacity.

The PSRP would address these objectives by replacing the transmission capacity of the existing Line 1600 with a new 36-inch-diameter gas transmission pipeline, Line 3602.

SDG&E’s existing gas transmission system maps, including the proposed project, are shown below (Figures 2-1 and 3-2).

As the agency with jurisdiction over approval of the CPCN application, the CPUC is the “Lead Agency” for purposes of CEQA. The CPUC will prepare a Draft and Final Environmental Impact Report (EIR) to evaluate the proposed project’s potential impacts on the environment. Other regulatory agencies will work to support the CPUC Energy Division in the environmental review of the proposed project. The California Department of Fish and Wildlife (CDFW) is participating as a CEQA “Responsible Agency.” The California Department of Transportation also may participate as a CEQA “Responsible Agency.” Responsible agencies are state agencies, other than the CEQA Lead Agency (i.e., the CPUC), that are responsible for carrying out or approving the proposed project. The CDFW is also a CEQA “Trustee Agency” for the proposed project. CEQA “Trustee Agencies” are state agencies that have jurisdiction over resources that are held in trust for the people of the State of California and that would potentially be affected by the proposed project.

The CPUC reviewed the CPCN application and PEA for completeness. The CPUC deemed the PEA complete on August 23, 2016. Details pertaining to the status of and CPUC’s environmental review process can be found below in the CPUC Application Review Process section.

This site provides access to public documents and information relevant to the CEQA environmental review process. Additional project documentation will be posted as it becomes available.

Project Description

The proposed project includes the following components:

Construction of the proposed project would begin in the third quarter of 2019 and would take approximately 15 to 21 months to complete.

The EIR will evaluate a reasonable range of alternatives to the PSRP that could achieve all or most of the objectives of the proposed project, while avoiding or reducing one or more of its significant environmental impacts. Alternatives will include a “no project” alternative. In addition to the applicants’ proposed route for Line 3602, the CPUC anticipates evaluating the route alternatives shown on the figure below in the EIR. The CPUC may develop additional alternatives for consideration and analysis based on input received during the scoping period (see Notice of Preparation and Scoping section below) or in response to potentially significant environmental impacts identified during development of the EIR.

Project Location

The proposed project is located in San Diego County, California, and crosses: the cities of Escondido, San Diego, and Poway; unincorporated communities in San Diego County; and federal land (i.e. MCAS Miramar) (see Figure 1, Project Overview below). About 3.5 miles of pipeline would be located within MCAS Miramar. To view a more detailed map series of the proposed project in relation to highways and roads, please click here.

Notice of Preparation (NOP) and Scoping

On May 9, 2017, the CPUC distributed a Notice of Preparation (NOP) to potential responsible and trustee agencies under CEQA, interested parties, and members of the public. The purpose of the NOP was to inform recipients that the CPUC began preparation of an EIR for the proposed project and to solicit information and guidance on the scope and content of the environmental information to be included in the EIR and identify potential alternatives. The NOP included a description of the project that SDG&E and SoCalGas propose to construct, information regarding project location, a summary of potential project-related impacts, the times and locations of public scoping meetings, and information on how to provide comments. The NOP was circulated for a public review and comment period that began on May 9, 2017, and ended on June 12, 2017. Links to the CPUC’s NOP and related documents are provided in Table 1.

Scoping is the process used to gather comments and input from all potential responsible and trustee agencies, all other public agencies with jurisdiction by law over the proposed project, and members of the public early in the CPUC’s environmental review process. The comments and other information provided during the scoping process will help the CPUC determine the scope, focus, and content of the EIR and identify the range of alternatives, environmental effects, and mitigation measures to analyze in the EIR.

The CPUC conducted six public scoping meetings on three dates during the EIR scoping period (see Table 2). All interested parties, including the public, responsible agencies, and trustee agencies, were invited to attend the public scoping meetings to learn more about the proposed project, ask questions, and provide comments in person about the PSRP and the scope and content of the EIR. The CPUC also provided information about the proposed project and its decision-making process at each meeting in a variety of ways including a presentation and a series of fact sheets. Links to the fact sheets that were provided to stakeholders who attended the public scoping meetings and the presentation that was given by the CPUC during the scoping meetings are provided in Table 1. The scoping period began on May 9, 2017 and ended on June 12, 2017. All public scoping comments must have been received, or postmarked if hardcopy, by June 12, 2017.

The scoping period ended on June 12, 2017.

Draft EIR

The CPUC is preparing the Draft EIR. The Draft EIR is tentatively anticipated to be completed in the Summer of 2018. The Draft EIR will assess the proposed project’s environmental impacts, mitigation measures, project alternatives, and the environmentally superior alternative. Upon completion, the Draft EIR will be made available for public review and a 45-day public comment period. Stakeholders are encouraged to check this website frequently for changes in the Draft EIR schedule.

Public Meetings on the Draft EIR

The CPUC will hold public meetings during the 45-day comment period to discuss the Draft EIR and accept comments.

Final EIR

Following the closure of the Draft EIR comment period, the CPUC will prepare a Final EIR. The Final EIR will include responses to public comments received on the Draft EIR.

Project Need and Cost Review Proceeding

Administrative Law Judge’s (ALJ) Proceeding

In addition to the CPUC’s environmental review, the CPUC also appoints an ALJ to review the CPCN application with a focus on the need for and cost of the proposed project. This analysis aids the Commission in reaching a decision on the CPCN application. The CPUC’s proceedings website provides each of the CPUC ruling and decision documents associated with the proposed project. The CPUC proceedings for this project (Proceeding Number A1509013) is available by clicking here.

Decision

Upon conclusion of the project need and cost review proceeding, the ALJ will prepare a proposed decision for consideration by the CPUC commissioners, including a finding and recommendation regarding CEQA compliance. The ALJ will base the proposed decision on information collected as part of the environmental review process and the project need and cost review proceeding. The ALJ’s proposed decision is subject to a public comment period. After the public comment period, the CPUC Commissioners vote on whether to certify the EIR and adopt the ALJ’s proposed decision. The outcome of the vote will determine whether a CPCN is granted to construct the proposed project, the CPCN is denied, or an alternative to the proposed project is approved.

Join the CPUC Project Mailing List

You may join the CPUC’s PSRP mailing list to receive project updates and notification of the dates, locations, and times for the public scoping meetings and public meetings on the Draft EIR. To be added to the CPUC’s PSRP mailing list, please click here.

Submit a Public Scoping Comment

The CPUC solicited comments from all potential responsible and trustee agencies, all other public agencies with jurisdiction by law over the proposed project, and members of the public regarding the topics and alternatives that should be included in the EIR. The scoping period began on May 9, 2017, and ended on June 12, 2017.

Comments must have been received, or postmarked if hardcopy, by June 12, 2017.

All comments received during scoping, including the names and addresses of those who comment, will be made part of the public record for the proposed project and may be made publicly available.
