Williams Seeks FERC OK to Begin 55-Mile Southeast Pipeline Construction

Williams’ Transco has secured its final federal authorization and is asking FERC for a Notice to Proceed on its 55-mile, 42-inch Southeast Supply Enhancement pipeline across Virginia and North Carolina, targeting a March construction start.

(P&GJ) — Williams’ Transcontinental Gas Pipe Line Company (Transco) has asked the Federal Energy Regulatory Commission (FERC) for authorization to begin construction on its 55.3-mile Southeast Supply Enhancement Project after securing its final federal permit.

In a Feb. 20 filing under Docket No. CP25-10-000, Transco told FERC it has obtained a fully executed U.S. Army Corps of Engineers (USACE) Section 404 permit, satisfying the final environmental condition tied to the Commission’s Jan. 29 certificate order.

The project includes 55.3 miles of 42-inch-diameter natural gas pipeline across Virginia and North Carolina. Specifically, the buildout consists of approximately 28.5 miles in Rockingham, Guilford, Forsyth and Davidson counties in North Carolina, and 26.8 miles in Pittsylvania County, Virginia.

The USACE permit authorizes temporary impacts to streams, wetlands and open waters associated with pipeline installation, as well as permanent conversion of certain wetland areas for ongoing right-of-way maintenance.

Transco said issuance of a Notice to Proceed by March 2 is necessary to comply with time-of-year restrictions and conservation measures recommended by the U.S. Fish and Wildlife Service.

The permit allows construction to be completed by Dec. 31, 2031.

The Southeast Supply Enhancement Project is designed to add capacity to Transco’s system serving markets in the Southeast, with the expansion consisting of new large-diameter pipe and associated facilities in Virginia and North Carolina.
