This bill proposes several updates to current statutes regarding water management and environmental funding in Arizona. Specifically, it modifies the fee structure for Arizona water banking purposes in the Tucson and Phoenix active management areas, allowing the director to set the fee rather than capping it at $2.50 per acre-foot per year. Additionally, the bill extends the period during which no fee will be levied in the Pinal active management area from 2026 to 2030 and maintains the fee for groundwater and irrigation efficiency projects in that area until 2030. It also adjusts the timeline for the distribution of unencumbered funds to contributors, extending the deadline from 2027 to 2032.

Furthermore, the bill introduces new provisions for fiscal year 2026-2027, allowing the Department of Environmental Quality to utilize funds from the underground storage tank revolving fund for administrative costs and remediation efforts in border areas. It also permits the Arizona navigable stream adjudication commission to use appropriated funds for legal fees and allows the Arizona water protection fund commission to grant funds to the Department of Water Resources for administrative costs. Lastly, it establishes a cap on the appropriation from the state general fund to the water quality assurance revolving fund for the same fiscal year.
