The bill amends existing Florida statutes to address issues related to former phosphate mining lands. It introduces new provisions that allow landowners to record a notice identifying their property as a former phosphate mine, as defined in the newly created section 378.213. This notice serves to inform potential buyers and the public about the land's history. Additionally, the bill requires the Department of Health to conduct gamma radiation surveys of these lands upon request from current landowners, ensuring that any potential radiation hazards are assessed and documented.

Furthermore, the bill establishes specific requirements for civil actions related to phosphate mining, mandating that plaintiffs include a radiation survey with their complaints. This survey must be conducted by certified professionals and must document gamma radiation levels, including background values and testing methodologies. The bill aims to enhance transparency and safety regarding former phosphate mining sites, providing legal defenses for property owners under certain conditions related to natural geological substances from these mines. The act is set to take effect on July 1, 2025.
