The bill amends existing Florida statutes to establish new regulations and requirements concerning former phosphate mining lands. It introduces a new defense in civil actions related to these lands, stating that if the condition leading to the lawsuit is due to natural geological substances from a former phosphate mine, and if a notice has been recorded and a radiation survey conducted by the Department of Health, then the defendant may not be held liable. Additionally, the bill creates a new section that allows landowners to officially record their property as a former phosphate mine, serving as public notice of its status.

Furthermore, the bill mandates the Department of Health to conduct gamma radiation surveys of former phosphate land parcels upon request from landowners, detailing the process and timeline for these surveys. It also requires that any civil action related to phosphate mining must include a radiation survey prepared by a certified professional, ensuring that the documentation meets specific standards and includes comprehensive details about the radiation levels on the property. The act is set to take effect on July 1, 2025.
