The U.S. Environmental Protection Agency (EPA) has extended the time period for requesting public comment to December 9, 2019, on two Underground Injection Control (UIC) Draft Area Permits and one associated proposed aquifer exemption decision for the Dewey-Burdock uranium in-situ recovery (ISR) site located near Edgemont, South Dakota, under the authority of the Safe Drinking Water Act and UIC program regulations. The Dewey-Burdock site is located in southwestern Custer County and northwestern Fall River County, on the Wyoming/South Dakota border.

The EPA Region 8 UIC Program is reissuing two Draft UIC Area Permits to Powertech (USA) Inc., Suite #140, 5575 DTC Parkway, Greenwood Village, Colorado 80111, for injection activities related to uranium recovery. One is a UIC Class III Area Permit for injection wells for the ISR of uranium; the second is a UIC Class V Area Permit for deep injection wells that will be used to dispose of ISR process waste fluids into the Minnelusa Formation after treatment to meet radioactive waste and hazardous waste standards. The EPA is also re-proposing an aquifer exemption approval in connection with the Class III Area Permit to exempt the uranium-bearing portions of the Inyan Kara Group aquifers. The EPA requested public comments on these permit actions in March 2017. After reviewing the comments received and modifying the draft actions, the EPA is requesting additional public input on these actions. At the close of the public comment period, the EPA will review and consider all comments received during both the 2017 and 2019 public comment periods and during all the public hearings and make decisions on final actions. The EPA will also prepare a written statement addressing all the comments received that are relevant to the UIC Class III and V Draft UIC Area Permits.
