On August 7, 2007, the Oglala Sioux Tribal Council passed Ordinance 07-40 which declares Pine Ridge Indian Reservation and the aboriginal territorial boundaries of the Oglala Sioux Tribe to be a "Nuclear Free Area" and provides that any person, agency or entity who shall cause any nuclear pollution or contamination to enter the confines of the Reservation, including its 1851 & 1868 Treaty boundaries and aboriginal territory boundaries, "shall be prosecuted to the fullest extent of the law."

On October 31, 2007 Oglala Sioux Tribal Court Judge Lisa Adams ruled against Native American Energy Group and ordered the uranium speculation company to be removed and excluded from the Reservation for doing business without a license.

Work continues at Pine Ridge to gather data concerning the health and environmental impact of historic and current uranium mining upwind and upstream of the Reservation. Recently, 98 wells were closed at Pine Ridge. NAEG is appealing the court's decision to the Sioux Supreme Court.
