The fight against the proposed Dewey-Burdock uranium mine has been ongoing since the mid-2000s. Powertech/Azarga is proposing an in-situ leach uranium mine in ancient Winter Camp area, north of Edgemont in Fall River and Custer counties.

Federal permits (Nuclear Regulatory Commission, Environmental Protection Agency, Bureau of Land Management)

In 2010, Oglala Sioux Tribe (OST) filed a lawsuit against the Nuclear Regulatory Commission (NRC) over its license for this project, based on its inadequate cultural resources analysis and several environmental concerns, including wastewater disposal and containment, especially due to abandoned open pit uranium mines and unreclaimed boreholes from past mining at the site. The NRC license for Dewey-Burdock has been issued, but it’s currently being challenged by OST, both before the NRC and in federal court.

In November 2020, the Environmental Protection Agency (EPA) also issued permits for this project, and OST once again formally objected. The EPA never even began consultation with OST for this project, in violation of various federal laws, including the National Historic Preservation Act and the National Environmental Policy Act.

This project still needs a Plan of Operations from the Bureau of Land Management (BLM) (proposed Plan of Operations was released for 30 days of public comment in July 2020).

SD permits (DENR)

Dewey-Burdock still needs permits from the Department of Environment and Natural Resources (DENR), from the Board of Minerals and Environment and from the Water Management Board. Powertech applied for both permits in 2012 but in 2013, both boards decided to postpone the permit process under the federal permits had been resolved.
