FERC Clears Mountain Valley Pipeline to Begin Southgate Construction in North Carolina
According to Pipeline & Gas Journal, federal regulators have authorized Mountain Valley Pipeline to begin construction of the North Carolina portion of its Southgate Amendment Project, clearing a major hurdle for the long-delayed natural gas expansion.
In a June 24 notice, the Federal Energy Regulatory Commission’s Office of Energy Projects approved Mountain Valley Pipeline’s request to commence construction activities in North Carolina after determining the company had satisfied applicable pre-construction requirements associated with the project. The authorization applies to facilities covered under the Southgate Amendment Project in Docket No. CP25-60-000.
FERC said it reviewed the company’s implementation plan and supplemental filings submitted throughout 2026 and concluded Mountain Valley had provided the information necessary to satisfy the project’s pre-construction conditions. The agency also confirmed that the company had obtained the federal authorizations required for the project.
The approval allows construction to move forward on the North Carolina facilities associated with the Southgate expansion. FERC reminded the company that it must continue to comply with all remaining terms and conditions contained in the commission’s December 2025 certificate order.
The Southgate Amendment Project has faced a lengthy regulatory and legal gauntlet, including a prior December 2023 FERC certificate approval, a December 2025 revised certificate for a modified route and capacity, and a June 2026 appeals court ruling rejecting environmental groups’ bid to halt the project with a stay.
What It Means for Subcontractors
- Construction authorization from FERC opens the North Carolina facilities to active site work. Pipeline contractors, HDD crews, grading and civil crews, and environmental compliance specialists in the Carolinas should expect pre-construction mobilization activity in the near term.
- The Southgate project will extend Mountain Valley Pipeline’s existing Appalachian system into North Carolina, connecting natural gas infrastructure from West Virginia through Virginia and into the Southeast — a corridor that has seen strong demand growth.
- Contractors already working on MVP’s mainline should monitor for Southgate subcontracting opportunities, as Mountain Valley typically uses established midstream construction vendors for extension projects at this scale.
