This bill establishes regulations to prohibit weather and climate modification activities in South Dakota, creating a framework for monitoring and enforcement. A new fund, the weather and climate modification monitoring fund, will be established to collect fines from violations and support the Department of Agriculture and Natural Resources in monitoring prohibited activities, investigating complaints, and assessing civil penalties. The bill specifies that no person may inject or release harmful chemicals into the atmosphere for the purpose of modifying weather conditions, with penalties set at a minimum of $100,000 for violations, plus $10,000 for each day the violation continues.

Additionally, the bill mandates the creation of an online reporting system for suspected violations, outlines the responsibilities of public and private airport operators to report aircraft capable of weather modification, and requires the Department of Transportation to forward these reports to the appropriate authorities. Starting July 1, 2026, reporting requirements will be incorporated into grant agreements with public airports. The South Dakota Aeronautics Commission is tasked with developing necessary rules and templates for compliance. Furthermore, businesses intending to disperse chemicals from outside the state must notify the secretary of state with a list of the substances involved.
