Bill summary
Licensing Structure
- The Department of Water Resources (DWR), which manages the state’s water, issues weather modification licenses. The Department of Environmental Quality (DEQ), responsible for environmental protection, must review each permit.
- DWR must issue the license within 120 days of a complete application.
- Each license remains valid for one year, and the licensee may renew it within 30 days.
- DWR and DEQ split the $100 application fee based on their respective responsibilities.
- Federal agencies and state political subdivisions must now follow the exact licensing requirements.
Environmental Review
- DEQ will create rules for an approved list of chemicals and their maximum amounts.
- DEQ reviews chemical compliance applications within 30 days.
- The agency based the approved chemicals list on industry guidelines, practices from other Western states, and environmental impacts.
Public Participation Requirements
- The public in the proposed operation area must receive written notice.
- There is a required period for public comments.
- The applicant must hold at least one public meeting in the likely affected area within 30 days after providing notice.
- Before each operating season, licensees must publish a newspaper notice that includes operational details and agency contact information.
Application Requirements
- Applicants must specify the type of modification, such as increasing rainfall, reducing hail, or dispersing fog.
- Applicants must provide an estimated water volume in acre-feet (an acre-foot is the amount of water needed to cover one acre of land to a depth of one foot) and explain the method used to calculate it.
- All chemicals, compounds, substances, and quantities
- Applicants must identify any potentially affected watersheds, rivers, streams, and floodplains.
- The applicant must include a projected weather forecast and its source.
- Applicants must provide proof of insurance or financial surety.
Operational Controls
- The director must set suspension criteria that align with industry guidelines and those used by other Western states.
- Operations must stop when suspended. Licensees are required to monitor weather conditions and stay informed about suspension criteria.
- Licensees must actively monitor weather conditions and be aware of suspension criteria.
- A "Material change" (different chemicals or a substantial increase in quantity) requires a new application.
Reporting Requirements
- The licensee must complete a final evaluation within 90 days of the project's end.
- Semi-annual reports are required while projects are ongoing.
- Reports must include seeding hours ("seeding" means the process of dispersing substances into clouds to modify weather), estimated acre-feet, chemicals used, and their volumes.
- DWR must send all reports to DEQ.
- The agency will immediately revoke the license if the licensee fails to file reports or notices.
Transparency
- The agencies will create a searchable online database of all licenses and applications.
- The database must let users download applications, licenses, and all DEQ documentation.
- The agencies will model their database after NOAA's weather modification database.
Liability
The state, DWR, DEQ, and their directors are not liable for damages that result from licensed operations.
Exemption Preserved
Property owners can still use weather modification equipment for agriculture on their own land without a license.
Implementation
- Both agencies must adopt rules within 60 days after the law takes effect.
- The act will only apply once the rules are adopted.
History
HB 2125 was prefiled on January 6, 2026, by Representative Fink for Arizona's Fifty-seventh Legislature, Second Regular Session. "Prefiling" allows legislators to introduce bills before the session officially convenes, giving committees a head start on review. Arizona's 2026 session begins January 12, 2026, with scheduled adjournment on April 25, 2026.
The bill amends Arizona's existing weather modification statutes in Title 45, Chapter 9 (currently titled "Weather Control and Cloud Modification"), which have been on the books for decades but contain minimal regulatory requirements. The bill also repeals Section 45-1605, though the PDF does not show the contents of that repealed section. Arizona is one of several Western states with active cloud seeding programs, making this regulatory update practically significant rather than merely symbolic.
