Makes it unlawful to use weather modifications and authorizes DNR to bring a civil action for violations relating to weather modification

HB 2389 prohibits weather modification activities in Missouri, including cloud seeding and dispersing substances into the atmosphere to alter weather patterns. It directly affects individuals or entities conducting such activities, such as agricultural operations using cloud seeding. The law authorizes the Missouri Department of Natural Resources (DNR) to investigate reports via an online form, pursue civil lawsuits for violations, and seek damages or injunctions. It explicitly excludes standard pesticide use on farms and requires DNR to report violations to the National Oceanic and Atmospheric Administration (NOAA).
