(P&GJ) — The Federal Energy Regulatory Commission (FERC) has opened the environmental review process for the proposed Maysville Project, a natural gas pipeline expansion planned by Columbia Gulf Transmission, a subsidiary of TC Energy, in eastern Kentucky.
According to a notice published in the Federal Register, FERC staff will prepare an environmental document evaluating the potential impacts of constructing and operating new natural gas facilities in Rowan, Fleming and Mason counties. The review will inform the Commission’s decision on whether to issue a Certificate of Public Convenience and Necessity for the project.
Pipeline Route and Information

The Maysville Project is designed to provide 340,000 dekatherms per day of natural gas transportation capacity to serve the East Kentucky Power Cooperative’s Hugh L. Spurlock Power Station. The proposal includes construction of 42 miles of new 30-inch-diameter pipeline, a tie-in to the Columbia Gulf mainline, a new delivery meter station in Mason County, and three new mainline valves along the route.
FERC said construction would disturb approximately 770 acres of land, with about 260 acres maintained permanently for operation of the facilities once construction is complete. The remaining acreage would be restored to previous uses. Roughly 31% of the proposed route would follow or overlap existing utility corridors.
FERC said it plans to issue an Environmental Assessment (EA) for the Maysville Project by Aug. 11, 2026, with federal authorizations required by Nov. 9, 2026. Columbia Gulf filed its application for a Certificate of Public Convenience and Necessity under Section 7(c) of the Natural Gas Act on Nov. 17, 2025. The Commission has already received comments from landowners, state officials, local governments and stakeholders raising issues related to water resources, karst terrain, land use, safety and greenhouse gas emissions, according to the notice.
As part of the National Environmental Policy Act (NEPA) process, FERC is requesting public and agency input on potential environmental effects, alternatives and mitigation measures. Written and oral comments must be submitted by 5:00 p.m. ET on Feb. 6, 2026.
FERC staff will also hold two public scoping sessions in the project area:
- Jan. 28, 2026 in Maysville, Kentucky
- Jan. 29, 2026 in Flemingsburg, Kentucky
FERC will use the scoping process to inform its Environmental Assessment and determine whether additional environmental review is required.
