AI Summary
This bill establishes a comprehensive regulatory framework to prohibit solar radiation modification (SRM), geoengineering, and other atmospheric interventions involving pollutant release in New Hampshire. The legislation defines a wide range of technical terms related to atmospheric activities, including cloud seeding, weather engineering, and machine learning, and creates strict enforcement mechanisms. Under the bill, any entity or individual engaging in prohibited atmospheric interventions would commit a felony, facing potential fines up to $500,000, imprisonment for up to two years, and potential additional penalties under existing pollution laws. County sheriffs are empowered to issue immediate cease-and-desist orders, conduct random aircraft and equipment checks, and deputize volunteer citizens to assist with enforcement. The bill also requires detailed scientific evaluations of communication facilities, including electromagnetic radiation assessments, and mandates that any federally or foreign-approved programs must still meet the state's requirements. The Air National Guard is authorized to interdict and document potential violations, including escorting non-compliant aircraft to airports for investigation. The legislation frames these prohibitions as necessary to protect human health, environmental resources, and state sovereignty, with the law set to take effect on January 1, 2027.
