Radiation Regulations Development
  • We evaluated revisions to 6 CCR 1007-1 Part 18, "Licensing Requirements for Uranium and Thorium Processing" and several issues connected to the enabling legislation, the Colorado Radiation Control Act (Title 25, Article 11).
    • The evaluation was driven by comments received from the U.S. Nuclear Regulatory Commission (NRC) in a 2011 letter addressing incompatability issues between the Radiation Control Act and NRC requirements.
    • Issues surrounding the Energy Fuels project also revealed discrepancies among the Radiation Control Act, Administrative Procedures Act and the radiation regulations.
  • Changes were identified that could be made to the radiation regulations without creating problems related to the Radiation Control Act, including establishing a clearly defined public process for license decisions that extends beyond the time period already specified in the Radiation Control Act.
