BISMARCK, N.D. (KFYR) Activists who tried to disrupt oil pipeline operations in four states to protest the Dakota Access pipeline say they are not responsible for any of the attacks.
Energy Transfer Partners, the company building the pipeline, says it remains on track to start moving oil this week, in spite of "coordinated physical attacks along the line."
The information comes from a court document that was filed late Monday. The company did not disclose details of the attacks, but did say they pose threats to life, physical safety and the environment.
A spokesman for the company and the Morton County Sheriff's Department declined to comment.
Tuesday, Mahaska County Sheriff's Department in Iowa confirmed there was damage inflicted to a safety check valve along the line.
They say it looks like someone used a blow torch to damage the valve on March 15.
