The U.S. Army Corps of Engineers plans to issue Energy Transfer Partners LP the last permit it needs to finish the controversial Dakota Access oil pipeline, two North Dakota lawmakers said. Acting Army Secretary Robert Speer directed the Army Corps to move forward with the easement necessary to build the final leg of the $3.8 billion crude line under North Dakota’s Lake Oahe, North Dakota Senator John Hoeven said in an e-mailed statement Tuesday, citing a conversation he had with Speer.
