Bill > HB2389

This bill makes it unlawful to use weather modification techniques in Missouri, defined broadly as any intentional activities designed to artificially change atmospheric conditions, such as cloud seeding, dispersing substances into the air to alter cloud processes, or dropping pollution or biological agents from aircraft. The bill authorizes the Missouri Department of Natural Resources (DNR) to investigate reports of weather modification and bring civil actions against violators, potentially resulting in damages, injunctive relief, and attorney's fees. The DNR is required to create an online form for reporting potential weather modification incidents and must report any known instances to the National Oceanic and Atmospheric Administration. The bill includes an important exemption for pesticide use in farming and ranching operations. The legislation also empowers the DNR to create rules and regulations for implementing these provisions, with the understanding that any such rules must comply with existing state administrative procedures. The bill aims to regulate and potentially prevent human-induced atmospheric manipulation that could potentially harm the environment or food supply.
