Relating to the storage or disposal of high-level radioactive waste.

HB 4692 prohibits the storage or disposal of high-level radioactive waste in Texas, with limited exceptions. The bill amends Texas Health and Safety Code sections 401.0525(c) and 401.072 to block state permits for new facilities storing such waste (licensed by the U.S. Nuclear Regulatory Commission under 10 C.F.R. Part 72), except at operational or former nuclear power reactor sites and university-operated research reactors. It directly affects entities seeking to establish new waste storage or disposal facilities in Texas, including compact waste facility license holders. The bill takes effect immediately if passed with a two-thirds vote, or September 1, 2025, otherwise.
