Location : Cameron, Calcasieu, Beauregard, Allen, Evangeline and St. Landry Parishes, Louisiana and Orange and Jefferson Counties, Texas
Capacity : 2.0 Bcfd
Size : 131 miles, 42-inch diameter pipeline
Proposed Commercial Operation : Q2 2023

The proposed Port Arthur Pipeline Louisiana Connector (PAPLC) project will provide an additional, reliable solution to transport natural gas as a feed gas source to the proposed Port Arthur Liquefaction Project.

The PAPLC project will follow a route, mostly collocated with other pipelines through Cameron, Calcasieu, Beauregard, Allen, Evangeline and St. Landry Parishes in Louisiana as well as Orange and Jefferson Counties in Texas.

  • Map
  • The proposed PAPLC project will include the following facilities:

  • Approximately 131 miles of 42-inch diameter pipeline
  • A compressor station in Allen Parish
  • Multiple interconnects
  • Associated above and below ground equipment, including valves and launchers/receivers
  • The PAPLC project will be owned and operated by Port Arthur Pipeline with a total operating capacity of approximately 2.0 billion cubic feet per day (Bcfd).

    Project Status

    PAPLC initiated the pre-filing process with the Federal Energy Regulatory Commission (FERC) in March 2017. The project submitted a FERC application in October 2017 and received authorization in April 2019. Construction is expected to begin in Q2 2021, with commercial operations expected in Q2 2023.

    Development of the Port Arthur Liquefaction Project and the PAPLC project is contingent upon completing the required commercial agreements, securing all necessary permits and approvals, obtaining financing and incentives, achieving other customary conditions, reaching a final investment decision and other factors associated with the investments.
