What the agency says
This notification is announcing that on April 20, 2026, Ho K. Nieh, Chairman of the U.S. Nuclear Regulatory Commission (NRC or Commission), and on April 21, 2026, Governor Mark Gordon of the State of Wyoming, signed an amended Agreement as authorized by Section 274b. of the Atomic Energy Act of 1954, as amended (AEA). Under the amended Agreement, the Commission discontinues its regulatory authority, and the State of Wyoming assumes regulatory authority over source material recovered from any mineral resources processed primarily for purposes other than its uranium or thorium content. Wyoming's initial Agreement allowed the State to assume regulatory authority over byproduct material as defined in section 11e.(2) of the AEA, and source material involved in the extraction or concentration of uranium or thorium in source material and ores at milling facilities.
