The company building the Dakota Access oil pipeline wants a federal judge to block the U.S. Army Corps of Engineers from launching a full environmental study of the $3.8 billion pipeline’s disputed crossing of a Missouri River reservoir in North Dakota.  Texas-based Energy Transfer Partners asked U.S. District Judge James Boasberg on Tuesday to stop the Corps from publishing a notice in the Federal Register announcing the study.  Boasberg scheduled a hearing for today.

 
ETP wants any further study put on hold until Boasberg rules on whether the company already has the necessary permission to lay pipe under Lake Oahe — the reservoir that’s the water source for the Standing Rock Sioux tribe.  ETP wants to block further study so that the decision on the permitting will be “free from the risk that its ruling will be frustrated or thwarted by new governmental actions.”  The Corps did not immediately respond to ETP’s request.
