This bill introduces several amendments and new provisions related to former phosphate mining lands in Florida. It amends section 376.308 to include a new defense for liability claims, stating that if the condition leading to a lawsuit is due to 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 officially record 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 certified radiation survey with their complaint, detailing specific information about radiation levels and testing methodologies. The bill is set to take effect on July 1, 2026.
