ND agency orders probe of oil pipeline leak

BISMARCK, N.D. (AP) — State regulators have opened a formal investigation of an oil pipeline accident in southeastern North Dakota.

A fitting failure at a pumping station in TransCanada's Keystone pipeline spilled more than 14,000 gallons of oil.

North Dakota's Public Service Commission voted Friday to investigate the spill.

Commission Chairman Tony Clark says the move allows the commission to take testimony and gather evidence about the accident. It also allows North Dakotans who are interested in the spill to take part in the case.

The pipeline delivers oil from Canada's Manitoba province to Illinois and Oklahoma. It was shut down when the spill happened last Saturday.

A TransCanada vice president said the pipeline began shipping oil again on Friday. Vern Meier (MY’-ur) says it should reach full capacity within several days.
