If enacted, this bill would update current statutes by allowing municipal providers in the Pinal active management area (AMA) to assume replenishment obligations for member service lands within their service area when applying for a new designation of assured water supply. Specifically, it would amend the existing law to include the Pinal AMA alongside the Phoenix AMA, thereby broadening the scope of areas where these provisions apply. The bill also clarifies that member lands can retain their replenishment obligations, and it mandates that the Central Arizona Groundwater Replenishment District must replenish groundwater in accordance with these obligations.

Additionally, the bill requires the Arizona Department of Water Resources to amend its rules related to the assured water supply program by January 1, 2026. This amendment will incorporate extinguishment credits and groundwater allowances associated with member lands, ensuring that the updated regulations align with the new provisions established by this bill. Overall, the changes aim to enhance the management of groundwater resources in the Pinal AMA while maintaining the responsibilities of municipal providers and member lands.
