(Trevor Christensen | The Salt Lake Tribune) Construction equipment gathers radioactive mill tailings at the Utah Moab Uranium Mill Tailings Remedial Action (UMTRA) Project on Wednesday, Aug. 14, 2024. The 480-acre site was once the home of a uranium mill that processed 1,400 tons of uranium ore per day. In 1998, the owner of the mill, Atlas Minerals Corporation, declared bankruptcy. In 2001, the U.S. Department of Energy began the work of cleaning up the 16 million tons of radioactive waste left behind. The site sits just outside Moab on the banks of the Colorado River.
