Belle Fourche pipeline rupture

The Associated Press has a nice primer on the recently discovered rupture of the Belle Fourche pipelineĀ in North Dakota. Among other details, the article compares the Belle Fourche to the Dakota Access pipeline, which has been the target of protest at Standing Rock and elsewhere.

The Belle Fourche is a 6-inch steel “gathering” pipeline built in the 1980s to transport oil to collection points, where it then “moves into larger pipelines or railroad tankers destined for refineries across the U.S.”

The Dakota Access is a 30-inch steel “transmission” pipeline that will carry 20 million gallons of oil daily some 1,200 miles to a shipping point in Illinois.

Debate over the Dakota Access project has centered on pipeline safety, especially risks to water supplies. Advocates argue that pipelines are safer than other transportation options, such as truck or rail.

Pipeline leak in ND

A pipeline leak was recently discovered just a couple hours drive from a camp where protesters are challenging construction of the Dakota Access Pipeline.

According to the report, more than 176,000 gallons of crude oil leaked from the Belle Fourche Pipeline into the Ash Coulee Creek. The leak was discovered on December 5 by a landowner near the city of Belfield and was contained soon after by Wyoming-based True Cos., the company which operates the pipeline. True Cos. operates three pipeline companies with 1,648 miles of line in Montana, North Dakota and Wyoming.

Electronic monitoring equipment failed to detect the Belle Fourche Pipeline leak. The 6-inch steel pipeline was built in the 1980s and is mostly underground. The spill migrated almost 6 miles from the point where leak originated.

The report states that “True Cos. has a history of oil fieldā€“related spills in North Dakota and Montana, including a January 2015 pipeline break into the Yellowstone River. The 32,000-gallon spill temporarily shut down water supplies in the downstream community of Glendive, Montana, after oil was detected in the city’s water treatment system.”

True Cos. has reported 36 spills since 2006, totaling 320,000 gallons of petroleum products.
