The bill amends existing Florida statutes to establish new regulations and requirements concerning former phosphate mining lands. It adds a new paragraph to section 376.308, allowing for a defense in legal actions if the cause of action arises from natural geological substances of a former phosphate mine, provided that a notice has been recorded and a radiation survey has been conducted by the Department of Health. Additionally, it creates section 378.213, which outlines the process for landowners to record their property as a former phosphate mine, and defines what constitutes a "former phosphate mine."

Furthermore, the bill introduces section 404.0561, mandating the Department of Health to conduct gamma radiation surveys of former phosphate land parcels upon request from landowners, with specific timelines for survey completion and reporting. It also establishes section 768.405, which requires plaintiffs in civil actions related to phosphate mining to include a radiation survey with their complaint, detailing the methodology and qualifications of the person conducting the survey. The bill is set to take effect on July 1, 2025.
