ARIZONA STATE SENATE
Fifty-Seventh Legislature, First Regular Session
FACT SHEET FOR S.B. 1518
subsequent AMAs; groundwater portability
Purpose
Allows an owner of an irrigation grandfathered right (IGFR), in a subsequent active
management area (AMA), to use, sell, transfer or lease the IGFR and the water duty that was
associated with those acres. Allows a person that receives a sold, leased or transferred associated
water duty to use the associated water duty anywhere in the subsequent AMA for irrigation use
and to further convey the associated water duty.
Background
In an AMA, a person who was legally withdrawing and using groundwater as of the date
of the designation of the AMA or who owns land legally entitled to be irrigated with groundwater
has the right to withdraw or receive and use groundwater as determined by the Director of the
Arizona Department of Water Resources (ADWR). There are three categories of grandfathered
rights as follows: 1) non-irrigation grandfathered rights associated with retired irrigated land;
2) non-irrigation grandfathered rights not associated with retired irrigated land; and 3) IGFR. In
an AMA, a person who owns land which was legally irrigated in whole or in part with groundwater
at any time during the five years preceding the date of the notice of the initiation of designation
procedures or the call for the election for subsequent AMA, which is capable of being irrigated
and which has not been retired from irrigation for a non-irrigation use has the right to use
groundwater for the irrigation of such land. The owner of an IGFR may convey the right only with
the land to which the right is appurtenant (A.R.S. §§ 45-462; 45-465; and 45-472).
The Director of ADWR may designate an area which is not included within an initial AMA
and a subsequent AMA if the Director of ADWR determines that: 1) active management practices
are necessary to preserve the existing supply of groundwater for future needs; 2) land subsidence
or fissuring is endangering property or potential groundwater storage capacity; or 3) use of
groundwater is resulting in actual or threatened water quality degradation. A groundwater basin
that is not included within an initial AMA may be designated an AMA on petition by 10 percent
of the registered voters residing within the boundaries of the proposed AMA which triggers a
subsequent election held pursuant to the general election laws of Arizona (A.R.S. §§ 45-412 and
45-415). Currently, the Douglas AMA, which was designated on December 1, 2022, after an
election and the Willcox AMA, which was designated on January 8, 2025, by the Director of
ADWR, are the only two subsequent AMAs in Arizona (ADWR: Douglas AMA and Willcox
AMA).
There is no anticipated fiscal impact to the state General Fund associated with this
legislation.
