EPA Decision Advances enCore Energy's Dewey Burdock Uranium Project to Federal Permitting Stage

enCore Energy's Dewey Burdock ISR Uranium Project

In a significant stride for the energy sector, enCore Energy Corp., recognized as America's Clean Energy Company™, has announced a crucial decision by the U.S. Environmental Protection Agency (EPA) concerning its Dewey Burdock In-Situ Recovery (ISR) Uranium Project. On September 16, 2025, the EPA's Environmental Appeals Board (EAB) rejected a petition from the Oglala Sioux Tribe and two environmental organizations that aimed to challenge the EPA's issuance of essential Underground Injection Control (UIC) permits for this project in South Dakota.

The Importance of the EPA's Ruling

This ruling is pivotal for enCore Energy, as it allows the Dewey Burdock Project to advance through federal permitting, with state permitting activities expected to commence in 2025. Robert Willette, the Acting CEO of enCore Energy, expressed optimism regarding the EAB's decision, emphasizing that it validates the permits and reinforces the integrity of the regulatory process. He remarked, "This outcome solidifies enCore's growth strategy and affirms our commitment to providing a secure, domestic uranium supply, essential for supporting America’s clean energy and national security initiatives."

The EAB's decision comes after years of administrative and judicial reviews, highlighting the regulatory complexities involved in uranium extraction projects. The petitioners argued that the EPA's decision violated several environmental statutes, including the Safe Drinking Water Act and the National Historic Preservation Act. However, after thorough evaluation, the EAB determined that the EPA acted appropriately and that the permits were appropriately substantiated by existing records.

Project Overview and Environmental Considerations

The Dewey Burdock Project is strategically located in Custer and Fall River counties, South Dakota. It employs ISR technology, which is known for being less environmentally invasive compared to traditional uranium mining methods. This innovative approach involves the use of a non-chemical, water-based solution to extract uranium from underground ores, thereby minimizing surface disruption. This marks a progressive step in ensuring energy production aligns with environmental stewardship.

As part of the Fast-41 Program approved on August 28, 2025, the project has received accelerated permitting to enhance domestic mineral production—a key focus of U.S. energy strategy. enCore Energy aims to expedite the development of the Dewey Burdock Project through federal and state regulatory pathways, ensuring compliance with all necessary safety and environmental standards.

Future Prospects and Community Engagement

EnCore Energy's commitment extends beyond just uranium production; it involves fostering relationships with local communities and indigenous governments. By collaborating with stakeholders, enCore aims to create positive impacts through its operations. Potential stakeholders can anticipate the benefits of job creation and local development associated with the project, while also prioritizing environmental sustainability.

This project underscores enCore's position as a leader in the sustainable uranium production sector, and it significantly contributes to America's energy independence. The company continues to work diligently to navigate the complex landscape of energy production while adhering to the highest regulatory and environmental standards. The Dewey Burdock ISR Uranium Project stands as a testament to the future of clean energy and responsible resource management.

In summary, the EAB's ruling is not just a victory for enCore Energy, but a crucial development for securing a stable and secure domestic uranium supply that is critical for the advancement of clean energy initiatives across the United States. As the project progresses through further permitting stages, the anticipation and support from various sectors reflect a growing recognition of the importance of sustainable mining practices in achieving national energy goals.
