Port Arthur Pipeline Texas Connector

Port Arthur Pipeline, LLC, is proposing to develop a natural gas pipeline in connection with the proposed development of the Port Arthur LNG project.


Jefferson and Orange Counties, Texas; Cameron Parish, Louisiana


2.0 Bcfd


34.2 miles, 42-inch diameter pipeline

The 26.6-mile northern portion of the proposed Port Arthur Pipeline Texas Connector (PAPTC) project would extend from Vidor in Orange County, TX to the proposed liquefaction project, with the majority of the proposed pipeline co-located with existing energy infrastructure rights-of-way. The approximately seven-mile southern portion of the proposed Pipeline Project would originate in Cameron Parish, Louisiana on the east bank of Sabine Lake and terminate at the Port Arthur Liquefaction Project.

The proposed PAPTC project would interconnect the Port Arthur LNG project to various intra- and interstate pipelines, providing access to a number of major U.S. natural gas supply basins.

Project Status

Port Arthur Pipeline Texas Connector received authorization from the Federal Energy Regulatory Commission (FERC) in April 2019 (Docket No. CP17-21-000). All other required permits have been received.

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

  • Provides a new source of revenue for local providers of goods and services
