On June 15, 2026, Southeast Supply Header, LLC (SESH) filed an application in Docket No. CP26-543-000 requesting a Certificate of Public Convenience and Necessity pursuant to Section 7(c) of the Natural Gas Act to install, replace, modify, and operate certain natural gas compressor station facilities. The proposed project is known as the Tupelo Trail Project (Project) and would provide up to 110,000 dekatherms per day of natural gas to the Plant Daniel electric generation facility in Jackson County, Mississippi.

On June 30, 2026, 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 document for the Project.

This notice identifies Commission staff's intention to prepare an environmental assessment (EA) for the Project and the planned schedule for the completion of the environmental review.^[1]

Schedule for Environmental Review

Issuance of EA—February 12, 2027

90-day Federal Authorization Decision Deadline ^[2] —May 13, 2027

If a schedule change becomes necessary, additional notice will be provided so that the relevant agencies are kept informed of the Project's progress.

Project Description

SESH proposes to install, replace, modify, and operate compression facilities and related appurtenances at existing compressor stations in George and Jefferson Davis Counties, Mississippi, and Richland Parish, Louisiana. The Tupelo Trail Project would consist of the following activities:

• installing a new compressor unit powered by a 23,470-horsepower Titan 130 natural gas turbine and related appurtenances at the existing Lucedale Compressor Station in George County, Mississippi;
• replacing an existing compressor with a new compressor at the Lucedale Compressor Station;
• replacing the existing engine on Compressor Unit 2 at the Gwinville Compressor Station in Jefferson Davis County, Mississippi;
• uprating compressor units and increasing compression at the Delhi, Gwinville, and Lucedale Compressor Stations by modifying software controls that limit horsepower;
• and performing associated appurtenant activities.

Background

On July 22, 2026, the Commission issued a Notice of Scoping Period Requesting Comments on Environmental Issues for the Proposed Tupelo Trail Project (Notice of Scoping). The Notice of Scoping 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. In response to the Notice of Scoping, the Commission received comments from the U.S. Fish and Wildlife Services' Louisiana Ecological Services Office and the U.S. Environmental Protection Agency. The primary issues raised by the commenters concern air quality effects; waste disposal; and the use of the Information for Planning and Consultation tool for protected species effects determinations. All substantive comments will be addressed in the EA.
