Pipeline Safety & Reliability Project

About the project

The Pipeline Safety & Reliability Project is a proposed new, approximately 47-mile, 36-inch natural gas transmission pipeline from the Rainbow Metering Station near the Riverside County line to Marine Corps Air Station (MCAS) Miramar. The new pipeline will provide safe, reliable, clean and affordable natural gas to meet the region’s growing energy needs.

SDG&E’s natural gas system is part of a larger system jointly operated with Southern California Gas Company (SoCalGas). Through a network of transmission pipelines, SDG&E and SoCalGas deliver natural gas safely and reliably, across an approximately 20,000 square mile service area that includes the San Diego region.

San Diego County — the second largest county in California and the 17th largest metropolitan area in the United States — has a growing population of more than 3.2 million people and a regional economy of $179 billion. SDG&E provides safe and reliable natural gas through 873,000 natural gas meters in San Diego County — every day.

Proposed route

After extensive study and review, SDG&E has identified a proposed pipeline route that minimizes costs to our customers, and impacts to private property owners and natural resources. SDG&E proposes to locate the new pipeline underground, primarily within existing streets. Ultimately, the California Public Utilities Commission (CPUC) will determine the final route, but SDG&E believes the proposed route has the least impact to people and the environment.

Project timeline

SDG&E will coordinate and collaborate with residents, businesses, local government agencies, and others to provide information and gather input about our proposed new natural gas transmission pipeline. We’re committed to keeping communities informed about the project throughout the CPUC’s review process and during construction. Here’s the anticipated timeline:

  • Fall 2015 – Submit project application to the CPUC
  • 2015 – 2019 – CPUC review
  • 2019 – CPUC approval
  • 2020 – Begin construction
  • 2022 – Pipeline goes into service and pressure lowered on Line 1600
