LC 2241 Legislature · 2025 Regular Session

Prohibiting weather modification

Montana's LC 2241 prohibits intentionally releasing chemicals or substances from aircraft within the state for weather modification (like altering clouds, precipitation, temperature, or sunlight intensity). It directly affects entities conducting such activities, including potential federal operations, by banning these practices within Montana's borders. Key provisions require the Department of Justice to establish a public reporting system (email and online form) for violations and repeal all existing Montana laws governing weather modification permits and regulations. The bill replaces the previous regulatory framework with a strict prohibition and enforcement mechanism, focusing on protecting public health and environmental welfare as stated in the legislative findings.
