HB 2203: historical water use; subsequent AMA
Sponsor: Representative Griffin, LD 19
Committee on Natural Resources, Energy & Water
Overview
Extends the time period that is used when determining eligibility for continued groundwater
use or volume of groundwater use for an active management area (AMA) or subsequent AMA
designation.
History
After the initiation of the procedures for designating a subsequent AMA or for the call of an
election to establish an AMA an irrigation user is only permitted to irrigate on land that was
irrigated at any time during the five years preceding the beginning of the designation process.
This limitation exists until either the Director of the Department of Water Resources
(ADWR) makes a final determination or the results of the election to establish the AMA are
certified (A.R.S. § 45-416).
Type 1 non-irrigation grandfathered rights are associated with retired irrigated land and in
a subsequent AMA have the right to withdrawal the lesser of three acre-feet per acre per year
or the average annual amount of groundwater used per acre during the five year prior to
when the land was retired (A.R.S. § 45-463).
A person who owns land from which groundwater was being withdraw and used for non-
irrigation purposes as of the date of AMA designation can have a Type 2 non-irrigation
grandfathered right which can look at the five years preceding the designation to determine
the right to withdraw (A.R.S. § 45-464)
Provisions
