Ground Water Quality Program

Powertech (USA), Inc. - Ground Water Permits

 

Powertech (USA), Inc. is proposing to construct an uranium in situ leach mine and processing facility, located about 13 miles northwest of Edgemont, SD.  The legal location of the proposed exploration operation is portions of section 20, 21, and 27-35; T6S-R1E, Custer County and portions of sections 1-5, 10-12, 14 and 15; T7S-R1E, Fall River County. 
 

Powertech submitted a Ground Water Discharge Plan Application on March 9, 2012 for the land application of treated wastewater. The Ground Water Discharge Plan is one of several state and federal permits required before this proposed in situ leach mine may begin operation in South Dakota.  The purpose of this Plan is to ensure the protection of ground water resources by closely monitoring and evaluating surface discharges to ground water from the land application of treated wastewater, and establishing a groundwater protection plan and in the event of plan exceedances possible remediation requirements.


For more information on the Ground Water Discharge permitting process, please visit the Ground Water Discharge Permit web page.  

 
1- Powertech Ground Water Discharge Plan Status
 

The Department has a two stage review process for Ground Water Discharge Plans, consisting of a completeness review and a technical review.  The Department has determined the Ground Water Discharge Plan application to be procedurally complete on May 1, 2012.

 

The Secretary of the Department of Environment and Natural Resources is recommending conditional approval of the Ground Water Discharge Plan.  Conditions of the Ground Water Discharge Plan consist of land application effluent requirements, effluent, soil, stream and ground water monitoring and reporting requirements, application rate requirements, runoff prevention, contingency plan requirements, and technical revision authorization.
