MODERATE
This bill fundamentally shifts Arizona's water management strategy from a general 'water banking' system to a specific 'groundwater savings credits' program. It allows landowners in the Phoenix and Pinal active management areas to permanently give up their historical irrigation rights in exchange for tradable credits, which can then be used by municipalities to secure long-term water supplies. The legislation also establishes a temporary permit system to allow these landowners to continue farming for two years after relinquishing their rights.
Scope change
The bill narrows the scope from a broad water banking authority to a targeted groundwater program specifically for the Phoenix and Pinal active management areas, with a potential future expansion to the Tucson area.
ELIGIBILITY

Created a new mechanism for landowners to permanently relinquish irrigation grandfathered rights in exchange for 'groundwater savings credits'.

REQUIREMENT

Established strict criteria for issuing credits, including a requirement that land must have been irrigated with groundwater in at least three of the preceding five years.

DEFINITION

Defined 'groundwater savings credits' as a new asset type that can be pledged to municipalities seeking 'assured water supply' designations.

TIMELINE

Set a deadline of December 31, 2030, after which groundwater savings credits can no longer be pledged to new water supply applications.

ENFORCEMENT

Added prohibitions preventing the use of recovered groundwater on non-essential turf, water parks, or decorative features.

SCOPE

Replaced the general 'Arizona Water Banking Authority' reporting requirements with specific rules for the new groundwater savings program.

TECHNICAL

Created a temporary permit allowing landowners to continue irrigating for two years after relinquishing their rights to manage the transition.
