Workers plug Keystone pipeline in North Dakota to access site of spill

TC Energy Corp has plugged its Keystone crude oil pipeline in North Dakota, allowing workers to excavate a portion of the pipeline that leaked last week and determine the cause of the spill, a state official said on Tuesday.

Work will begin this week to access the precise point of the pipeline that leaked more than 9,000 barrels of crude in rural Walsh County, North Dakota, forcing the line to be shut, said Karl Rockeman, director of the state’s Division of Water Quality.

There is no estimated timeline for restart of the pipeline.
