An Act prohibiting solar radiation modification, cloud seeding and polluting atmospheric activity within this Commonwealth; imposing duties on the Pennsylvania State Police and sheriffs; and imposing penalties.

This bill, known as the Clean Air Preservation Act, prohibits any form of weather modification, cloud seeding, or atmospheric pollution within Pennsylvania. It defines these activities broadly to include actions taken by humans, machines, or artificial intelligence that release harmful substances or agents into the air. The Pennsylvania State Police and county sheriffs are tasked with enforcing the law by issuing immediate cease-and-desist orders that carry the same legal weight as a court order. Violators face severe penalties, including fines of at least $500,000, imprisonment for a minimum of two years, and potential charges under existing air pollution laws. The legislation also requires authorities to notify federal agencies if any government or foreign-approved projects attempt to conduct such activities within the state.
