Federal and state regulators said Friday there is no public health or safety risk because the spills remained on site and contained relatively low levels of uranium.
The largest known uranium reserves in the U.S. reside in Wyoming, but as a global commodity, the state's sector is moved, shaped and shaken by an international market.
A federal judge has ruled against an environmental group's challenge to an in-situ uranium mine that started production last month in Sweetwater County.
