TRP:CC - TC Energy to operate part of Virginia gas line at reduced pressure

2023-07-31 17:57:53 ET

TC Energy ( NYSE: TRP ) said Monday it plans to operate the Columbia Gas Transmission Pipeline at reduced pressure in a part of Virginia affected by an incident last week, in accordance with a corrective action order from the U.S. Pipeline and Hazardous Materials Safety Administration.

"The cause of the failure is currently unknown, but based on initial observations of the failed pipe, environmental cracking is the suspected cause," the PHMSA order said.

Natural gas feeding into the Cove Point LNG export plant in Maryland, operated by Berkshire Hathaway ( BRK.A ) ( BRK.B ), returned to normal operating levels Monday, Bloomberg reported, after the shutdown of part of the Columbia Gas system had reduced feedgas flows .

Columbia Gas declared force majeure last week and isolated a section of its Line VB pipeline in Virginia after detecting a pressure drop, reported at the time as caused by an explosion and fire.

TC Energy ( TRP ) said it is working to return to service the adjacent parts of the pipeline system not directly affected by the incident.
