South Dakota's HB 1181 takes a notably comprehensive approach by creating a dedicated enforcement fund, requiring quarterly aircraft inspections at all airports, and extending jurisdiction to businesses merely headquartered in the state, even when operations occur elsewhere. The $100,000 minimum fine plus $10,000 daily penalties represents one of the steeper civil penalty structures among similar state proposals.
South Dakota's HB 1271 creates a comprehensive prohibition on atmospheric modification, with substantial civil penalties ($100,000 minimum plus $10,000/day), funded through a self-sustaining enforcement mechanism in which collected fines pay for monitoring activities. The bill is notable for requiring all airports to file quarterly reports on aircraft equipped with dispersal equipment and for attempting to reach businesses operating from outside state borders through the Secretary of State disclosure requirements.
Deferred to 41st day by House Agriculture and Natural Resources committee
South Dakota's HB 1294 is a bare-bones geoengineering prohibition—just six lines of text making it a felony, with no enforcement infrastructure, no funding, and a narrow definition that specifically targets climate change countermeasures rather than weather modification generally.
