The bill amends existing Florida statutes to establish new regulations and requirements concerning former phosphate mining lands. It introduces a new cause of action against certain former phosphate mine sites under section 376.308, allowing for defenses related to natural geological substances of these sites, provided that a notice has been recorded and a radiation survey has been conducted by the Department of Health. Additionally, the bill creates section 378.213, which allows landowners to record a notice identifying their property as a former phosphate mine, and defines what constitutes a "former phosphate mine."

Furthermore, the bill mandates the Department of Health to conduct gamma radiation surveys of former phosphate land parcels upon petition from current landowners, as outlined in section 404.0561. The results of these surveys must be documented and shared with the petitioners. Lastly, section 768.405 requires that any civil action related to phosphate mining must include a radiation survey prepared by a certified professional, detailing the radiation levels on the property. The bill is set to take effect on July 1, 2025.
