This bill proposes several updates to the current statutes regarding groundwater management in the Big Chino subbasin of the Verde River groundwater basin. Key changes include the replacement of the term "sub-basin" with "subbasin" throughout the text, which clarifies the terminology used in the statute. Additionally, the bill introduces new requirements for cities and towns that wish to withdraw groundwater for transportation to the Prescott active management area. Specifically, it mandates that these entities obtain a certificate of adequate mitigation before proceeding with withdrawals, ensuring that they adhere to best practices for maintaining base flow, water quality, and natural flood flow cycles.

Furthermore, the bill outlines the criteria and processes for obtaining the certificate of adequate mitigation, including the need for annual reporting on groundwater withdrawal impacts and mitigation efforts. It also specifies that cities and towns must mitigate any degradation of base flow or water quality through various methods, such as recharging treated effluent or retiring irrigated acres. Overall, these updates aim to enhance the management and sustainability of groundwater resources in the region while ensuring compliance with environmental standards.
