FACT SHEET FOR S.B. 1432
prohibition; geoengineering
Purpose
Prohibits a person from intentionally injecting, releasing or dispensing by any means any
chemical, chemical compound, substance or apparatus within the borders of Arizona with the
express purpose of solar radiation management.
Background
Arizona requires any person or corporation, other than the United States and its
administrative agencies or the state, to obtain a license from the Director of the Arizona
Department of Water Resources (ADWR) prior to conducting any weather control or cloud
modification operations or attempts to artificially produce rainfall. Each licensee must, within 90
days after the conclusion of any weather control or cloud modification project, file with the
Director of ADWR a final evaluation of the project. Any individual or corporation engaging in
manufacturing, selling, leasing or licensing equipment and supplies designed for weather control
or cloud modification must, before engaging in such activity, procure a license from the Director
of ADWR.
Any person conducting weather control or cloud modification operations without first
having procured a license, or who knowingly makes a false statement in the application for license,
or who knowingly fails to file any statutorily required report or evaluation, or who conducts any
weather control or cloud modification operation after revocation of his or its license, or who
violates any other statutory requirement is guilty of a class 3 misdemeanor (A.R.S. Title 45,
Chapter 9). A class three misdemeanor has a maximum prison sentence of 30 days and a maximum
fine of $500 (A.R.S. §§ 13-707 and 13-802).
There is no anticipated fiscal impact to the state General Fund associated with this
legislation.
