active management areas; technical correction

SB 1187 is a technical correction to Arizona's groundwater law (Section 45-462) affecting users in active management areas (AMAs), which are designated regions with water management plans. It clarifies that transporting groundwater does not make a legal use illegal and confirms that the amount requested in a certificate of exemption application is recognized as a legal use for determining grandfathered rights. The bill also restates the three categories of grandfathered rights (non-irrigation on retired land, non-irrigation not on retired land, and irrigation rights) without creating new policies. This update resolves minor ambiguities in existing law to ensure consistent application for groundwater users in AMAs.
