A subcontractor for the Dakota Access oil pipeline was killed in an apparent accident in North Dakota, a state regulator announced Saturday.
The man, whose name has not yet been released, died of his injuries on Friday afternoon according to North Dakota Public Service Commissioner Brian Kalk.
Kalk said the man was working alone on a tractor on Thursday to cover the underground pipeline with soil and grass seed when he suffered a major head injury while using the equipment. He was then taken to a Minot hospital.
Kalk reported that the company has no reason to believe the cause of his death was anything but a “terrible accident.”
Regulators have said they expect a full report on the incident by early this week, according to Kalk.
