LD 825 Maine Senate · 132nd Legislature (2025-2026)

An Act To Prohibit Geoengineering, Including The Use Of Cloud Seeding, Weather Modification, Excessive Radio Waves And Microwave Radiation

Maine's LD 825 prohibits any "geoengineering" activity within the state, including cloud seeding, weather modification, and excessive radio/microwave radiation emissions. The law defines "geoengineering" broadly as intentional large-scale interventions in Earth's systems, such as stratospheric aerosol injection or harmful radiation levels exceeding specific technical thresholds (e.g., -85 decibel-milliwatt for radio signals). The Maine Department of Environmental Protection enforces the ban, with violators facing Class C crimes and daily fines up to $500,000. This law directly affects individuals, companies, or entities conducting such activities in Maine, including potential federal or out-of-state operations impacting the state's atmosphere.
