AZ SB1636

Allows the Arizona Department of Water Resources director to designate subsequent irrigation non-expansion areas when groundwater is insufficient to provide a "reasonably safe supply" defined as a 100-year reliable source for irrigation

Establishes new petition requirements including submission within one year, a numeric groundwater flow model, and a hydrologic report signed by a registered professional geologist or engineer after consultation with the department

Limits irrigation within a proposed non-expansion area to only acres irrigated during the five years preceding the first publication of the hearing notice

Restricts judicial review of the director's designation order to petitioners and persons who submitted evidence at the public hearing, with review limited to issues raised during those proceedings

Imposes a three-year waiting period before a new petition can be filed if the director declines to designate an area as an irrigation non-expansion area
