This bill introduces several amendments and new provisions related to former phosphate mining lands in Florida. It amends section 376.308 of the Florida Statutes to include a new defense for liability claims, stating that if the condition leading to the cause of action is a natural geological substance from a former phosphate mine, and if a notice has been recorded and a radiation survey conducted, the defendant may not be held liable. Additionally, the bill creates section 378.213, allowing landowners to record a notice identifying their property as a former phosphate mine, and defines what constitutes a "former phosphate mine."

Furthermore, the bill establishes section 404.0561, which mandates the Department of Health to conduct gamma radiation surveys of former phosphate land parcels upon request from landowners. It also creates section 768.405, requiring plaintiffs in civil actions related to phosphate mining to include a radiation survey of the property with their complaint, prepared by a certified professional. This survey must document gamma radiation levels and adhere to specific standards. The bill is set to take effect on July 1, 2026.
