Bill > HB0012

This bill establishes the Wyoming Clean Air and Geoengineering Prohibition Act, which comprehensively bans atmospheric modification experiments and techniques within Wyoming's airspace. The legislation defines various technical terms like "geoengineering," "solar radiation management," and "atmospheric contaminants," and prohibits intentionally releasing substances designed to alter climate, weather, or solar radiation. The bill creates strict enforcement mechanisms, empowering the Wyoming Department of Environmental Quality to monitor airspace, investigate potential violations, and petition courts for cease and desist orders against offenders. Violations are treated as serious felonies, with first-time offenders facing up to two years in prison and fines between $100,000 and $500,000, and subsequent offenses carrying even more severe penalties. The law includes specific exemptions for activities like commercial aviation, agricultural operations, weather forecasting, and emergency services. To support implementation, the bill authorizes two new full-time positions at the Department of Environmental Quality and appropriates $500,000 for their funding. The legislation is grounded in legislative findings that express concerns about potential health and environmental risks from atmospheric modification experiments and asserts Wyoming's state sovereignty in protecting its airspace and citizens.
