HB 2798 Arizona House · 57th Legislature - Second Regular Session

appropriation; Arizona geological survey; study

HB 2798 appropriates funds to the University of Arizona’s Arizona Geological Survey to study minerals and metals needed for advanced nuclear reactors (including generation III+ and IV small modular reactors). The study requires mapping all known mineral reserves across Arizona, detailing quantities and grades for each site. The Geological Survey must submit a final report to state officials and publish it online by a specified deadline. This bill directly affects Arizona’s geological data collection efforts and state officials receiving the findings, with no direct impact on the public or businesses.
