Plain English Summary

AI-GENERATED
Raises the bar for lawsuits over phosphate-mining land contamination.

Former phosphate mine owners gain a new defense to pollution lawsuits if the contamination is natural geology, they have recorded a notice identifying the site, and the state has surveyed it for radiation.

Landowners may voluntarily record a notice marking their property as a former phosphate mine, a category that excludes phosphogypsum stacks, the radioactive waste piles left over from processing the ore.

The health department must survey a former phosphate parcel for gamma radiation within 120 days of a landowner's petition, and the landowner gets one chance to demand a redo within strict deadlines.

Anyone suing over phosphate-mining pollution, including claims tied to mine reclamation, must now attach a certified radiation survey to the complaint itself, prepared by a specifically qualified health physicist or technologist.

KEY PROVISIONS
§ 1 New defense for natural radioactivity at former phosphate mines majors. 376.308

AIAdds a defense to the closed list of defenses under the pollutant-discharge liability statute: a defendant can defeat a claim by showing the contamination is a natural geological substance of a former phosphate mine, provided notice was recorded and the state has surveyed the site.

“The condition giving rise to the cause of action is a natural geological substance of a former phosphate mine” bill text, line 27 →
§ 2 Voluntary notice-recording system, phosphogypsum stacks excluded majors. 378.213

AILets any landowner record a public notice marking land as a former phosphate mine, in a prescribed form, but the definition used throughout this scheme specifically excludes phosphogypsum stacks -- the radioactive waste piles from ore processing -- so those remain outside this notice-and-defense system.

“does not include a phosphogypsum stack as defined in s. 403.4154(1)(d)” bill text, line 52 →
§ 3 Health department must survey former mine parcels on request majors. 404.0561

AICreates a mandatory health department duty to run a gamma radiation survey of a former phosphate parcel within 120 days of a current landowner's petition, share preliminary results within 30 days, and conduct one additional survey within 90 days if the landowner requests a redo.

“the department shall conduct a gamma radiation survey of a former phosphate land parcel within 120 days after receipt of the petition” bill text, line 57 →
§ 4 Plaintiffs must file a certified radiation survey with the complaint majors. 768.405

AIAnyone suing over phosphate-mining pollution, hazardous discharge, or reclamation-related conditions must attach a radiation survey to the complaint itself, prepared and verified under oath by a certified health physicist or radiation protection technologist meeting detailed technical standards.

“the plaintiff must include a radiation survey of the property with the complaint” bill text, line 82 →
