temporary non-expansion area
HB 2570 establishes a process for creating "Temporary Non-Expansion Areas" in Arizona groundwater basins, limiting new irrigation development. It allows communities to petition for such areas if 50% of local irrigation users and 10% of registered voters sign a petition, followed by a public meeting and election. If approved, the area prohibits expanding groundwater irrigation to new land for 10 years, allowing only land that was irrigated during the prior decade to continue using groundwater. This directly affects agricultural landowners and water users within designated groundwater basins, requiring them to maintain existing irrigation levels without new expansion.

MODERATE
The bill was amended to shift from a House to Senate version, adding new reporting requirements for groundwater users, clarifying temporary non-expansion area rules, and modifying well drilling authorization procedures. The changes strengthen groundwater management by requiring annual reports, establishing withdrawal limits, and allowing temporary moratoriums to be extended based on hydrological analysis.
Scope change
The bill's scope expanded to include additional reporting obligations for groundwater users and clarified the conditions under which temporary non-expansion areas can be established or extended.
REQUIREMENT
New requirement for groundwater users to file annual reports with the director by March 31, including details about groundwater use areas and withdrawal amounts.
New requirement for water measuring devices to be used by persons withdrawing more than ten acre-feet of groundwater per year for non-irrigation uses.
Changed drilling card authorization rules to allow drilling in former temporary non-expansion areas rather than current ones.
ELIGIBILITY
Modified rules for temporary non-expansion areas to allow continuation or lapse based on hydrological analysis conducted by the director.
