Tesoro Cleared to Restart North Dakota Line After Spill

Tesoro Corp. accepted a federal order requiring upgrades on its oil pipeline system spanning North Dakota and Montana that clears the company to restart a section shut since a 20,000-barrel spill discovered Sept. 29.

The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration, known as Phmsa, issued a safety order today allowing Tesoro to restart a 35-mile (56-kilometer) section of the 200-mile High Plains pipeline system. The order requires weekly aerial patrols of the line for a year and new leak detectors along all regulated sections of the High Plains system.
