2015 Regular Session
|
||||
| HB1420 | Waters and water rights; repealing the Oklahoma Weather Modification Act; effective date. | Passed | ||
| Oklahoma completely repealed its Weather Modification Act in 2015, eliminating state oversight of cloud seeding operations rather than adding restrictions. This represents the opposite trajectory of current 2025 legislative trends, where states are rushing to ban or regulate geoengineering activities. |

2025 Regular Session
Session Adjourn Fri 30 May 2025
|
||||
| SB1021 | Environment and natural resources; prohibiting certain actions relating to weather modification; providing for investigation. Effective date. | 1 Nov 2025 | Carried fwd | |
| 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. |

| SB430 | 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. | 1 Nov 2025 | Carried fwd | |
| 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. |

| Note: Carried forward to 2026 - New Legiscan record created | ||||
| HB1429 | Environment; prohibiting certain actions; emergency. | Immediately | Carried fwd | |
| 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. |

2026 Regular Session
Session Adjourn Fri 29 May 2026
|
||||
| SB1021 | Environment and natural resources; prohibiting certain actions relating to weather modification; providing for investigation. Effective date. | 1 Nov 2025 sic | Missed crossover | |
| 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. |

| SB430 | 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. | 1 Nov 2025 sic | Missed crossover | |
| 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. |

| SB1797 | Environmental and natural resources; prohibiting certain actions relating to weather modification. Effective date. | 1 Nov 2026 | Missed crossover | |
| 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. |
