Committee on Regulatory Oversight 
Overview 
Prohibits a person from intentionally injecting, releasing or dispensing any chemical, 
compound, substance or apparatus within Arizona's borders with the express purpose of solar 
radiation management.  
History 
Title 45, Chapter 9 (Weather Control and Cloud Modification) prohibits any person or public 
or private corporation, other than the federal or state government or their agencies, from 
conducting weather control or cloud modification operations or attempting to artificially 
produce rainfall without first obtaining a license from ADWR. An application for a license to 
conduct such operations must include all the information required by statute such as relevant 
names, addresses, scientific qualifications of all operating personnel and supervisors, areas 
to be served and dates of operations and evaluations that will be submitted.  An applicant 
must pay a $100 fee to submit an application, which deposits into the Water Resources Fund.     
Statute requires any person or corporation that seeks to manufacture, sell or lease, or offers 
to sell or lease any equipment or supplies for weather control or cloud modification, to first 
obtain a license. The license application must contain similar information as the operations 
application. The license fee is $10 and deposits into the Water Resources Fund. 
Exceptions to the license requirements include the use and operation of equipment and 
supplies for agricultural purposes used by the owner, lessee or licensee of real property. 
Current law classifies as a class 3 misdemeanor any violation of failing to obtain a proper 
license, knowingly making a false statement to obtain a license, knowingly failing to file the 
necessary evaluations or reports, continuing to operate after revocation of a license or 
violating any other provision of this law.
