This bill proposes amendments to section 45-576.09 of the Arizona Revised Statutes, specifically regarding groundwater management in the Phoenix active management area. Under current law, the director has the authority to revise rules to apply section 45-576.08 to other active management areas. However, the bill introduces a new provision that prohibits the director from adopting such rules for any city or town in the Phoenix active management area that has received a designation of assured water supply.

Additionally, the bill mandates that within thirty days of its effective date, the director of the department of water resources must conduct a review of the physical availability of groundwater and stored water for each city or town in the Phoenix active management area that holds a designation of assured water supply. This review is intended to ensure that the water resources are adequately assessed in light of the new restrictions imposed by the bill.
