AZ HB2572

Establishes provisions for "subsequent active management areas" (SAMAs) in addition to existing "initial active management areas," allowing the groundwater users advisory council in SAMAs to adopt management goals and plans with director review, rather than the director unilaterally establishing them.

Permits landowners in SAMAs to add acres, substitute acres, convey irrigation grandfathered rights, and combine multiple irrigation grandfathered rights within the same groundwater basin or subbasin, subject to director approval and existing water use limitations.

Modifies water supply adequacy requirements for subdivisions outside initial AMAs to also apply to SAMAs, requiring adequate water supply determinations for subdivision approvals in areas where counties or municipalities have adopted such provisions.

Changes the composition and appointment process for groundwater users advisory councils in SAMAs, making council members elected by local county boards of supervisors rather than gubernatorial appointees, and allows for recall elections in SAMAs.

Makes technical corrections throughout Arizona water law, including updated language for "initial active management areas" in relevant statutory sections governing groundwater management, subdivision approvals, and water supply assessments.
