HB1429 Died for lack of action

Environment; prohibiting certain actions; emergency.

Oklahoma's HB1429 would ban all intentional atmospheric modification while simultaneously dismantling the state's 50-year-old Weather Modification Act, but notably lacks any enforcement mechanism or penalties for violations.

Last action
SB1021 Died for lack of action

Environment and natural resources; prohibiting certain actions relating to weather modification; providing for investigation. Effective date.

Oklahoma's SB1021 would authorise the Air National Guard to intercept aircraft suspected of weather modification activities and escort them to airports for investigation, while simultaneously repealing the state's existing weather modification licensing program that has regulated cloud seeding operations for decades.

Last action
SB1797 Died for lack of action

Environmental and natural resources; prohibiting certain actions relating to weather modification. Effective date.

This bill authorizes the Governor to deploy the Oklahoma Air National Guard to intercept suspected weather modification aircraft, collect air samples using mass spectrometers, and escort violators to airports for investigation—while simultaneously dismantling Oklahoma's existing weather modification regulatory framework through a wholesale repeal of 23 statutory sections.

Last action
SB430 Died for lack of action

Environment; prohibiting intentional injection, release, or dispersion of chemicals, chemical compounds, substances, or apparatus in this state; repealing the Oklahoma Weather Modification Act. Effective date.

Oklahoma's SB430 is a companion bill to SB1021, using the same prohibition language but taking a conventional criminal penalty approach with misdemeanour charges and a $10,000 fine, rather than SB1021's Air National Guard interdiction authority.

2025 Regular Session

3 bills · Adjourned 30 May 2025
HB1429 Died for lack of action

Environment; prohibiting certain actions; emergency.

Oklahoma's HB1429 would ban all intentional atmospheric modification while simultaneously dismantling the state's 50-year-old Weather Modification Act, but notably lacks any enforcement mechanism or penalties for violations.

Last action
SB1021 Died for lack of action

Environment and natural resources; prohibiting certain actions relating to weather modification; providing for investigation. Effective date.

Oklahoma's SB 1021 authorises the Air National Guard to intercept aircraft suspected of weather modification and escort them to airports for investigation, but the bill contains no penalties for violators. This represents one of the more aggressive enforcement mechanisms proposed in any state, yet it is toothless due to the absence of any actual sanctions.

Last action
SB430 Died for lack of action

Environment; prohibiting intentional injection, release, or dispersion of chemicals, chemical compounds, substances, or apparatus in this state; repealing the Oklahoma Weather Modification Act. Effective date.

SB 430 is the simpler sibling to Oklahoma's SB 1021, which bans weather modification with a $10,000 misdemeanour fine but lacks the Air National Guard fighter jet provisions. Interestingly, Senator Jett (author of SB 1021) is a coauthor on this bill, suggesting the two may be legislative alternatives rather than competing approaches.
