More than three years later, N.D. Tesoro oil spill still not cleaned up
DECEMBER 19, 2016 —More than three years ago, 840,000 gallons of oil seeped from a pipeline break in North Dakota to contaminate the surrounding soil. Less than a third has been cleaned up.
In the wake of another spill this month, 150 miles further south, as well as the ongoing debate over the four-state Dakota Access pipeline, the slow progress of the Tesoro Corp. cleanup is causing some consternation.
The Tesoro break took place on a six-inch diameter pipeline, as did this month’s spill in Belfield. Neither is believed to have contaminated any water sources, but in the Belfield incident an estimated 176,000 gallons of oil spewed into a creek that feeds the Little Missouri River, a tributary of the Missouri River. Freezing temperatures appear to have limited the spread.
The six-inch pipelines are part of a network that spreads for thousands of miles all over western North Dakota’s oil patch.
By contrast, the Dakota Access pipeline – which has seen months of protests for environmental reasons, as well as concerns over the destruction of sacred sites – uses 30-inch pipes. The builder of that pipeline, Energy Transfer Partners, says that remote monitoring will allow workers to shut down the pipeline in case of a leak.
When oil spewed from the Belfield line earlier this month, monitoring equipment failed to detect the leak, and it fell to another farmer to raise the alarm." More than three years later, N.D. Tesoro oil spill still not cleaned up - CSMonitor.com
