(Trevor Christensen | The Salt Lake Tribune) A sign marks the border of the Utah Moab Uranium Mill Tailings Remedial Action (UMTRA) Project, located just outside Moab on the banks of the Colorado River, on Aug. 14, 2024. The cleanup of waste from the former uranium mill continues as companies propose reopening another mill in Utah and building a new one, spurred by higher uranium prices and interest in nuclear power.
