Final Issuance of EPA Dewey-Burdock Class III and Class V Injection Well Area Permits (September 2025)
The U.S. Environmental Protection Agency (EPA) issued two Underground Injection Control (UIC) Area Permits for injection activities related to the Dewey-Burdock Project in the southern Black Hills of South Dakota on November 24, 2020. One is a Class III Area Permit for injection wells used for the in-situ recovery (ISR) of uranium, and the other is a Class V Area Permit for deep injection wells that will be used to dispose of ISR process waste fluids. Information on these 2020 Permits and associated documents can be found at this weblink: https://www.epa.gov/uic/epa-dewey-burdock-class-iii-and-class-v-injection-well-final-area-permits-and-aquifer-exemption. These Permits were appealed to the Environmental Appeals Board (EAB).
In response to an Order by the EAB to remand the Permits in part, the EPA reviewed its documents and added to the administrative record, revised its response to comments document, and reissued the permits with no changes on March 14, 2025. A petition was filed with the EAB that challenged the permits on April 11, 2025, staying the effective date until after an EAB decision and final agency action. On September 12, 2025, the EAB issued a decision denying the petition for review in its entirety. Therefore, the EPA issued the final Dewey-Burdock UIC Class III and Class V Area Permits on September 25, 2025, in accordance with 40 C.F.R. § 124.19(l)(2).
