appropriation; uranium monitoring; mine inspector

HB 2889 appropriates $1 million from Arizona's general fund for fiscal year 2026-2027 to the state mine inspector to monitor uranium contamination. It requires the mine inspector to fund soil, water, and home testing for potential contamination and establish a statewide registry and monitoring program, partnering with tribal epidemiology centers. The bill mandates a report of findings and recommendations to state leaders by December 31, 2026. This funding is exempt from standard appropriation lapsing rules. The bill directly affects Arizona residents potentially exposed to uranium contamination, particularly in areas near mining sites.
