A heavy equipment operator working on the four-state, nearly 1,200-mile Dakota Accessoil pipelinein North Dakota died at a hospital in Minot, ND, Friday following head injuries sustained on the job. The man, whose identity has not been released, was working as a subcontractor for the $3.7 billion Energy Transfer Partners‘ pipeline project being built by Dakota Access Pipeline LLC. The incident occurred nearly 200 miles north and west of ongoing protests against the project by the Standing Rock Sioux Native American Tribe and some environmental groups near the South Dakota border. The man apparently was working alone and was found by co-workers.
