EPA, state approve uranium mining project in Wyoming aquifer
Decision supports energy development, protects groundwater
DENVER - Today, the U.S. Environmental Protection Agency (EPA) approved a request from the Wyoming Department of Environmental Quality (WDEQ) to allow the expansion of uranium mining in Sweetwater County, Wyoming.
The approval will allow projects to proceed in the Battle Springs Formation, an aquifer located throughout the Great Divide basin in south-central Wyoming. Working with the WDEQ, EPA determined that the aquifer, which contains uranium, is not a current and will not serve as a future source of drinking water. The decision will allow Lost Creek ISR, LLC, to expand their underground mining operations.
“Today’s decision will enable responsible energy development of critical uranium resources while protecting the groundwater of communities in Wyoming and create blue collar jobs along the way,” said Cyrus Western, EPA Regional Administrator. “This is what the Trump administration is about – restoring American energy dominance while ensuring clean air and water. We’re moving quickly, working with states and delivering results.”
The Underground Injection Control, or UIC, program prohibits the injection of fluids into aquifers like Battle Springs unless EPA exempts the portion containing commercially producible minerals, including uranium, that can be dissolved and extracted. The WDEQ issued a Class III injection well permit for this project and, today, EPA approved the aquifer exemption.
“This is a win for uranium production in Wyoming,” said Senator John Barrasso. “The Trump administration is delivering on its promise to unleash American energy. Nuclear power is clean and reliable and creates good paying jobs. Expanding uranium mining in the Battle Springs Formation will help ensure Wyoming continues to lead the United States in uranium production.”
“President Trump's decision to expand uranium mining in the Battle Springs Formation is a watershed moment for Wyoming's energy economy that not only recognizes our state’s vital role in the nation’s critical mineral supply chain but better positions us to achieve energy independence,” said Senator Cynthia Lummis. “By allowing Lost Creek ISR to expand their underground mining operations, President Trump and Administrator Zeldin are demonstrating their commitment to Wyoming’s hardworking families while ensuring we engage in responsible resource development that will strengthen Wyoming’s economy and America’s energy security for generations to come.”
“The WDEQ is pleased that EPA has concurred with Wyoming’s assessment and conclusion that the aquifer exemption is protective of drinking water sources and consistent with state and federal law,” said Todd Parfitt, WDEQ Director. “This action will allow for the responsible development of uranium resources while ensuring drinking water sources are protected.”
