Cameron Pipeline Expansion

Sempra is developing an expansion of its Cameron Interstate Pipeline.


Location : Cameron Parish, Louisiana
Capacity : 1.54 Bcfd
Size : 3 miles, 36-inch diameter pipeline
Commercial Operation : 2017

The proposed Cameron Interstate Pipeline Expansion Project (Expansion Project), which will consist of modifications to Cameron Interstate Pipeline’s existing gas transmission system in Beauregard, Calcasieu, and Cameron Parishes in Louisiana, is being developed to receive and transport domestic natural gas to the proposed liquefaction project at the Cameron LNG Terminal in Hackberry, Louisiana.

The existing Cameron Interstate Pipeline starts in Cameron Parish, adjacent to the site of the Cameron LNG Terminal and passes through Calcasieu Parish, terminating at the Ragley Compressor Station in Beauregard Parish.

The Expansion Project will add bi-directional flow to the Cameron Interstate Pipeline, which will allow the pipeline to transport gas from various interstate pipeline interconnections to the LNG Terminal. The project facilities will be designed so that the addition of the proposed facilities will not preclude Cameron Interstate Pipeline from receiving send-out gas from the Cameron LNG Terminal.

The following facilities will be constructed as part of the Expansion Project:

  • Approximately 3 miles of 36-inch-diameter pipeline
  • A new compressor station consisting of 7 CAT G3616 natural gas-driven compressors
  • Modifications to existing pipeline interconnections

    Project Timeline

  • April 2012: Pre-file application with Federal Energy Regulatory Commission (FERC)
  • December 2012: File application with FERC
  • April 2014: Environmental Impact Statement released by FERC
  • July 2014: Project approval
