WASHINGTON (November 5, 2025) – The Federal Permitting Improvement Steering Council (Permitting Council) welcomes the Mississippi Crossing and South System Expansion 4 projects to FAST-41 coverage. Together these pipeline projects will play a key role in addressing the growing need for natural gas in the Southeast.
“On behalf of the Trump Administration, I am pleased to welcome the Mississippi Crossing and South System Expansion 4 projects to FAST-41 coverage,” said Emily Domenech, Permitting Council Executive Director. “We’re excited to add more pipeline projects to our Permitting Dashboard and to continue developing domestic energy resources needed to meet the demand for baseload power in the Southeast.”
Located in Greenville, Mississippi, the Mississippi Crossing pipeline project is designed to provide up to 2.1 billion cubic feet of natural gas transportation capacity to meet growing demand in the Southeast. The $1.7 billion project will enhance access to multiple, diverse and abundant supply basins, strengthening supply reliability and market flexibility across the region. The project will include 199 miles of new pipeline extending from Greenville, Mississippi southeast to Butler, Alabama.
Located in Enterprise, Mississippi, the South System Expansion 4 project will expand natural gas capacity by approximately 1.3 billion cubic feet per day to serve markets across the Southeastern U.S., from Clarke County, Mississippi to Aiken, South Carolina and Savannah, Georgia. The project consists primarily of brownfield looping and compression additions across approximately 291 miles of existing assets, with limited new greenfield segments.
“Given the size and complexity of each project, the number of federal agencies involved, and the need for these projects to move through permitting quickly so that our customers can realize their benefits, we believe the additional coordination, oversight, and leadership of the Permitting Council can help us bring these projects to fruition promptly,” said Ernesto Ochoa, Vice President and Chief Commercial Officer for Tennessee Gas Pipeline Company, L.L.C. and Southern Natural Gas Company, L.L.C.
The Mississippi Crossing and South System Expansion 4 projects are both sponsored by Kinder Morgan Inc. The Federal Energy Regulatory Commission (FERC) leads federal permitting for these projects.

About the Permitting Council and FAST-41
Established in 2015 by Title 41 of the Fixing America’s Surface Transportation Act (FAST-41), the Federal Permitting Improvement Steering Council (Permitting Council) is a federal agency charged with improving the transparency and predictability of the federal environmental review and authorization process for certain critical infrastructure projects. The Permitting Council is composed of the Permitting Council Executive Director, who serves as the Council Chair; 13 federal agency Council members; and the Chair of the White House Council on Environmental Quality and the Director of the Office of Management and Budget. The Office of the Executive Director coordinates federal environmental reviews and authorizations for projects that seek and qualify for FAST-41 coverage, which are in turn entitled to comprehensive permitting timetables and transparent, collaborative management of those timetables on the Federal Permitting Dashboard.
