The Standing Rock Sioux Tribe is asking a federal judge to temporarily stop work on parts of the Dakota Access Pipeline to prevent the destruction of sacred and culturally significant sites near Lake Oahe.
A hearing on the tribe's motion for a temporary restraining order is Tuesday before U.S. District Judge James Boasberg. The tribe wants construction stopped on the pipeline route for a length of about two miles west of Highway 1806 and within 20 miles on either side of Lake Oahe.
If granted, the order would stop construction there while Boasberg weighs a broader request to halt construction on the pipeline. He will rule on that request by Friday.
The tribe is challenging federal regulators' decision to grant permits for the $3.8 billion pipeline, which would cross the Dakotas and Iowa to Illinois.
