01:58 PM EDT, 04/08/2025 (MT Newswires) -- South Bow ( SOBO ) on Tuesday said it shut down its Keystone oil pipeline following a spill from the line in North Dakota.

The company, spun out earlier this year from TC Energy (TRP.TO) to hold its liquids pipelines, said the spill occurred at milepost 171, near Fort Ransom, ND.

"Aligned with our incident protocols, we initiated a shutdown and response at approximately 7:42 a.m. CT on April 8, 2025, after control center leak detection systems detected a pressure drop in the system. The affected segment has been isolated and operations and containment resources have been mobilized to site," the company said.

The company did not say how much oil leaked from the line, however a CTV News report said the oil was contained in an agricultural field 274 meters from a pumping station.

The pipeline carries oil sands crude from Alberta to refineries in Illinois, Oklahoma and the gulf coast.

The company's shares were last seen down $2.05 to $31.20 on the Toronto Stock Exchange.
