The regulators ordered Cotter to build berms around the 300 to 500 tons of uranium ore by Nov. 17 and to remove the uranium by early next year. “The worry is that an inactive mine can have maintenance and upkeep problems. It could cause polluted runoff,” said Bob Randall, deputy director of Colorado’s Department of Natural Resources. “What we want Cotter to do is clear it. They’ve got to put the berms up. They’ve got two weeks to do it.” Regulators also have ordered Cotter to submit an environmental protection plan.
Separately, Colorado Department of Public Health and Environment officials are poised to renew Cotter’s water-discharge permit for the mine, requiring compliance with current federal standards, said Steve Gunderson, the agency’s water-quality director…
Cotter’s mine sits on federal Bureau of Land Management land, leased by the U.S. Department of Energy. It is one of several uranium sites where state environmental overseers are pressing Cotter for cleanup action.
