US Uranium Mining and Exploration - World Nuclear …

Most US uranium-producing states are 'agreement states' vis a vis the Nuclear Regulatory Commission (NRC) and have authority to issue permits and regulate uranium mining and milling. The NRC's role is then minimal. In February 2015 Wyoming, the major uranium production state, passed legislation to make it an agreement state, along with all the other uranium-producing states.
