subsequent irrigation; non-expansion areas; procedures

HB 2513 creates a new process for Arizona to designate "subsequent irrigation non-expansion areas" where new irrigation development is restricted. It allows the state director to formally identify groundwater areas that lack sufficient water to support additional irrigation at current withdrawal rates, provided an active management area isn't needed. The bill establishes procedures for these designations, including requirements for petitions from either 25 irrigation users (meeting specific land-use criteria) or 10% of registered voters in the affected basin, backed by scientific groundwater models and hydrologic reports. This directly affects farmers and landowners in designated groundwater basins by preventing new irrigation projects in areas with inadequate water resources.
