Bill summary (AI generated)

South Carolina Bill H4010 is also cited as the "South Carolina Clean Air Act". It was introduced on 13 February 2025, and referred to the Committee on Judiciary. 

Similar to H3915, H4010 states that the risk to human health and environmental welfare from broadscale geoengineering is more understood. The core prohibition makes it unlawful to intentionally inject, release, or disperse chemicals, chemical compounds, substances, or apparatus, and energy frequencies manipulation, in the atmosphere within the state's borders. This is prohibited if the purpose is affecting temperature, weather, or the intensity of storms and the dimming of the sunlight. The prohibitions include manipulating weather systems via aerosol injection for the purpose of intensifying the weather to harm persons or to destroy or damage tree farms or other property. 

The bill outlines several specific exemptions, stating that the provisions do not apply to any person whose cloud seeding is a result of a publicly approved contract or a person that is lawfully crop dusting. Additionally, H4010 requires the Department of Environmental Services (DES) to make information available to the public detailing the harmful effects from released chemicals, and ensures that the state Freedom of Information Act cannot be used to prohibit the release of documents concerning stratospheric aerosol injection or other prohibited conduct. 

The act takes effect upon approval by the Governor. (Note: Unlike H3915, H4010 does not explicitly include the felony penalties or the private action clause in the provided excerpts).
