Standing Rock Sioux Tribe files new federal lawsuit challenging Dakota Access Pipeline operation

The Standing Rock Sioux Tribe has filed a new federal lawsuit against the U.S. Army Corps of Engineers and the Pipeline and Hazardous Materials Safety Administration (PHMSA). The lawsuit challenges federal decisions that allow the Dakota Access Pipeline (DAPL) to continue operating beneath Lake Oahe, which is the Tribe's sole source of drinking water. The Tribe argues that federal officials failed to adequately address concerns about pipeline safety, potential oil spills, cultural resources, and Treaty rights.
