prohibit weather and climate modification activities and provide a penalty therefor.

HB 1271 prohibits the intentional release of specific chemicals (like aluminum barium, sulfur dioxide, or PFAS-containing chaff) into the atmosphere for weather modification, directly affecting operators of equipment used for such activities. It establishes a $100,000 minimum civil penalty per violation (plus $10,000 daily for ongoing violations) and creates a dedicated monitoring fund to cover enforcement costs. The bill requires airports to report aircraft equipped with weather-modification devices (excluding standard agricultural sprayers) to the Department of Transportation, which forwards reports to the Agriculture Department for investigation. Key mechanisms include online violation reporting, departmental investigation rules, and airport compliance reporting starting July 2026.
