subsequent active management area; designation.

SB 1254 expands Arizona's groundwater management by allowing the director to designate new "subsequent active management areas" beyond the initial zones. It applies to communities where groundwater preservation is needed, land subsidence threatens property, or water quality is degrading. The bill requires new areas to cover entire groundwater basins (except northern Arizona's regional aquifers) and mandates regular reviews of non-managed areas to determine if they meet the criteria. This creates a formal process for adding groundwater basins to regulated management zones.
