Modifies criteria of hazardous waste investigations and increases the hazardous waste fund appropriations
HB 516 creates a dedicated "Radioactive Waste Investigation Fund" within Missouri's state treasury to investigate potential radioactive contamination. It directs the Department of Natural Resources to use this fund - funded by annual transfers of up to $1 million from the hazardous waste fund - to conduct scientific investigations in areas where local governments request them, prioritizing sites near known radioactive contamination. The bill requires public reporting of preliminary findings for 90 days, final reports with test results, and soil/water sampling (with homeowner permission in residential areas) to assess if contamination exceeds EPA standards. Any unused funds revert to the hazardous waste fund at year-end.
