The "Wyoming Clean Air and Geoengineering Prohibition Act" aims to prohibit the release of atmospheric contaminants in Wyoming's airspace, addressing concerns over atmospheric modification experiments that may pose risks to public health and the environment. The act defines key terms such as "atmospheric contaminant," "geoengineering," and "weather modification," and establishes that no person shall intentionally inject or disperse any atmospheric contaminant for the purpose of altering climate or weather. The act allows for certain exemptions, including commercial aviation and agricultural crop dusting, and empowers the director of the Department of Environmental Quality to issue cease and desist orders for violations.

Additionally, the act includes provisions to protect whistleblowers who report violations, imposes criminal penalties for offenders, and mandates the development of necessary rules for enforcement. It repeals previous weather modification statutes that are deemed obsolete, thereby streamlining the legal framework surrounding atmospheric interventions in Wyoming. The act is effective immediately upon its passage, ensuring prompt implementation of its provisions.
