The owners of the Dakota Access Pipeline on Tuesday said it was moving equipment to prepare for tunneling under Lake Oahe, the water source that has been a focus of protests, even as federal regulators have not given a go-ahead signal that the line will be able to proceed. Army Corps spokesman Thomas O’Hara told Bloomberg News on Monday that the company had agreed to slow down construction, a statement Energy Transfer refuted. "The statement released last night by the Army Corps was a mistake and the Army Corps intends to rescind it," Energy Transfer said in a statement released on Tuesday. "To be clear, Dakota Access Pipeline has not voluntarily agreed to halt construction of the pipeline in North Dakota."
