FLAGSTAFF, Ariz. -- The U.S. Environmental Protection Agency says a uranium mine north of the Grand Canyon is operating in violation of the law and its owner could face thousands of dollars in fines.
The EPA contends Denison Mines Corp. failed to apply for and obtain federal approval for its Arizona 1 Mine, about 20 miles from the Grand Canyon's northern border.
The EPA says former approval for the mine expired when it became inactive in the early 1990s. Denison restarted operations late last year and plans to mine 110,000 tons of uranium ore per year at the site.
Denison President Ron Hochstein says he was surprised by the notice and is working with the EPA to address the issues raised.
