According to Sarah Fields:
Uranium mining is still a dirty, polluting , hazardous, and environmentally destructive industry. State and federal regulatory programs are still back in the 1980s. Some kinds of emissions are not regulated (same story at uranium mills), and there are no clean up standards for the mines after decommissioning. There are still many uranium mining areas in Colorado, New Mexico, Arizona, and Utah that have never been cleaned up. A federal staff person recently described an area on public land in Utah with historical uranium mining impacts and 2 small proposed mines as a "War Zone."
