Standing Rock Sioux Tribe Files New Federal Lawsuit Challenging Dakota Access Pipeline Easement

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 allowing the Dakota Access Pipeline (DAPL) to continue operating beneath Lake Oahe, the Tribe's sole source of drinking water, citing risks of an oil spill and violations of Treaty rights and sovereignty.
