Crude Leak Contained, Soil Being Remediated
A 20-year old pipeline running from Tioga, N.D., to Columbus, N.D., has drawn major attention following a leak that spilled more than 20,000 barrels of crude oil into a wheat field. The pipeline, operated by Tesoro Logistics, has been temporarily shut down. Repairs are underway, crude has been contained and remediation is underway, according to Tesoro. The remediation efforts will cost Tesoro Logistics roughly $4 million.
There is some good news in the incident. “The release hasn’t impacted any surface waters, and Tesoro Logistics has been aggressive in containing crude oil,” said Kris Roberts, environmental geologist, division of Water Quality, N.D. Department of Health. “I am very pleased with the company’s proactive response efforts.”
According to the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration, the Tesoro spill equals the total for all spills in North Dakota over the past 10 years combined. The spill is not a record breaker however, according to Roberts.
At press time, state regulators were still investigating the cause of the leak, but early indications show the leak was caused by corrosion. Officials were also determining when the leak was first noticed and when Tesoro was informed of the leak.
