Start Preamble

On March 29, 2019, Gulf South Pipeline Company (Gulf South) filed an application in Docket No. CP19-125-000 requesting a Certificate of Public Convenience and Necessity pursuant to Section 7(c) of the Natural Gas Act to construct and operate certain natural gas pipeline facilities. The proposed project is known as the Index 99 Expansion Project, and would consist of the construction of a new pipeline, new launcher and receiver facilities, a new mainline valve, and modifications to an existing compressor station. All project components are in Texas and Louisiana. The project would provide about 500 million cubic feet/per day (MMcf/d) of new natural gas firm transportation service to markets along the Gulf Coast region, as well as provide for an additional 250 MMcf/d of capacity to Gulf South's existing facilities in northern Louisiana, for a total maximum daily quantity of 750 MMcf/d.

On April 12, 2019, the Federal Energy Regulatory Commission (Commission or FERC) issued its Notice of Application for the project. Among other things, that notice alerted agencies issuing federal authorizations of the requirement to complete all necessary reviews and to reach a final decision on a request for a federal authorization within 90 days of the date of issuance of the Commission staff's Environmental Assessment (EA) for the project. This instant notice identifies the FERC staff's planned schedule for the completion of the EA for the project.

Project Description

The proposed project consists of the following facilities:

  • installation of a pig [1] receiver at the intersection of the new Index 99L pipeline and Gulf South's existing Index 99 System, in San Augustine County, Texas;
  • installation of a pig launcher at the intersection of the new Index 99L pipeline and Gulf South's existing Index 99 System and Index 129 Legacy System, in Sabine County, Texas;
  • installation of one new mainline valve assembly along the new Index 99L pipeline, in San Augustine County, Texas; and
  • installation of approximately 250 feet of new 24-inch-diameter station pipe and a 24-inch-diameter pressure control valve at the existing Hall Summit Compressor Station in Bienville Parish, Louisiana.


On May 13, 2019, the Commission issued a Notice of Intent to Prepare an Environmental Assessment for the Proposed Index 99 Expansion Project and Request for Comments on Environmental Issues (NOI). The NOI was sent to affected landowners; federal, state, and local government agencies; elected officials; environmental and public interest groups; Native American tribes; other interested parties; and local libraries and newspapers. All substantive comments received will be addressed in the EA.
