U.S. federal regulators on Thursday, Jan. 29, authorized a controversial natural gas pipeline expansion that will cut through several North Carolina counties, despite fierce opposition from local residents and environmental advocacy groups.

The Federal Energy Regulatory Commission (FERC) gave the green light to the Southeast Supply Enhancement Project, a major natural gas pipeline proposed by Williams to provide additional energy reliability in the region. 

Managed by Transcontinental Gas Pipeline Co. LLC (Transco), the project expands an existing system that transports natural gas from the Texas Gulf Coast to New York City. 

The scope of the North Carolina portion of the expansion includes:

The proposed Salem Loop route travels northeast from a compressor station north of Lexington, passing through Wallburg, Midway, and Welcome, before stretching east of Kernersville and into the Oak Ridge area.

Planned to cross more than 150 streams and wetlands across the state, the project has drawn more scrutiny due to potential environmental concerns. 

Opponents argue that construction will permanently damage these ecosystems, increase air pollution, and depress property values, while also raising concerns about the risk of explosions.

Transco officials stated that once construction is finished, all streams and wetlands will be restored "as near as practical" to their original condition. 

The company noted that pipelines are monitored 24/7 via aerial patrols, ground monitoring, and regular leak inspections.

Following the announcement, a coalition including the Sierra Club, Appalachian Voices, and 7 Directions of Service issued statements condemning the federal approval.

“The decision ignores the vocal opposition of thousands of people,” said Caroline Hansley, a strategist for the Sierra Club. 

Hansley noted that with this authorization, the project now has the authority to use eminent domain to take private property.

“Communities are not willing to sacrifice their health and environment for fossil fuel profits,” Hansley said.

Filed by FERC in early 2024, the pipeline expansion proposal has faced opposition, delaying its approval despite the company having the right of way.
