The proposed Port Arthur Pipeline Louisiana Connector will transport and provide natural gas to the proposed Port Arthur LNG liquefaction project.


Cameron, Calcasieu, Beauregard, Louisiana; Orange and Jefferson Counties, Texas


2.0 Bcfd


72 miles, 42-inch diameter pipeline

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

The Port Arthur Pipeline Louisiana Connector project will follow an approved route, mostly collocated in existing rights-of-way with other infrastructure. Active development of 72 miles of pipeline will occur through Cameron, Calcasieu, and Beauregard Parishes in Louisiana, as well as Orange and Jefferson Counties in Texas.

The proposed Port Arthur Pipeline Louisiana Connector project will include the following facilities:

  • Approximately 72 miles of 42-inch diameter pipeline

  • A compressor station in Beauregard 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

Port Arthur Pipeline Louisiana Connector received Federal Energy Regulatory Commission (FERC) authorization in April 2019 (Docket No. CP18-7-000). The project submitted an application amendment to relocate a compressor station and received FERC authorization for the amendment in October 2020 (Docket No. CP20-21-000). In July 2023, the project filed an application amendment to make minor route modifications in July 2023 (Docket No. CP23-513-000). All other major regulatory permits have been acquired as well.

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