Plain English Breakdown
The bill text uses strike-through and replacement language (e.g., 'June 12, 1980' replaced by 'the date of the designation...') which indicates a change in how the cutoff date is determined for non-initial AMAs. The summary reflects this distinction.
SB1287: Expanding Groundwater Use for Stock Watering and Domestic Needs
This bill extends the right to withdraw up to 10 acre-feet of groundwater annually for domestic use or stock watering from initial active management areas to all active management areas, provided specific historical usage conditions are met.
What This Bill Does
- Extends the existing rule allowing IGFR holders in initial Active Management Areas (AMAs) to withdraw up to 10 acre-feet of groundwater annually for domestic purposes or stock watering to holders in any AMA.
- Requires that this water be withdrawn from wells currently used for irrigation on land covered by an Irrigation Grandfathered Right certificate.
- Mandates that the right applies only if, as of June 12, 1980 (for initial AMAs) or the date the AMA was designated (for other AMAs), groundwater from those wells was already being used for domestic purposes or stock watering.
- States that no Type 2 non-irrigation grandfathered right certificate has been issued based on these withdrawals.
- Clarifies that if a separate meter measures this water use, it is exempt from certain conservation rules; otherwise, it counts toward irrigation usage reports and flexibility account debits/credits.
- Defines replacing an old well with a new one in the same or a different location as being considered the 'same well' for these rights.
Who It Names or Affects
- People who hold certificates of Irrigation Grandfathered Rights (IGFR) within any Active Management Area.
- The Director of the Arizona Department of Water Resources, who oversees groundwater withdrawals and reporting requirements.
- Landowners using wells to irrigate certificated acres while also needing water for household or livestock needs.
Terms To Know
- Active Management Area (AMA)
- A specific region in Arizona where groundwater use is regulated by the state due to high usage levels.
- Irrigation Grandfathered Right (IGFR)
- A legal right allowing landowners to continue using groundwater for irrigation based on historical use before certain regulations took effect, tied specifically to certificated acres.
- Stock Watering
- The act of providing water to livestock, range livestock, or poultry as defined in state law.
Limits and Unknowns
- This right is lost if the Irrigation Grandfathered Right is retired or conveyed for a non-irrigation use.
- Water withdrawn under this rule must be used only on the same land and for the same purpose as it was historically used before the cutoff date (June 12, 1980, or AMA designation date).
- The bill does not specify an exact effective calendar date in the provided text, stating instead that it becomes effective on a general future date.
Amendments
These notes stay tied to the official amendment files and metadata from the legislature.
Plain English: This amendment updates Arizona water laws to allow farmers with irrigation rights in specific areas to use up to ten acre-feet of groundwater per year for household needs and watering livestock, provided they were already doing so when the area was designated as an active management zone.
- It changes the rule from using a fixed date (June 12, 1980) to using the specific date each Active Management Area is officially created.
- It clarifies that 'stock watering' means providing water for livestock and poultry as defined by state law.
- It states that if this water use is not measured separately from irrigation water, it will be counted toward the farmer's total irrigation usage limits.
- The text does not explain what happens to wells or rights in areas designated before June 12, 1980.
- Specific details about how 'replacement wells' are approved by officials are not included in this summary of the amendment.

- The amendment does not explain how a person proves they were using the water on the exact date an area was designated.

FACT SHEET FOR
S.B. 1287
stock watering;
active management areas
Purpose
Allows a person who holds a certificate of an irrigation grandfathered
right (IGFR) in any active management area (AMA), rather than in an initial
AMA, the right to annually withdraw up to 10 acre-feet of groundwater for
domestic purposes or stock watering from a well or wells the holder is using to
withdraw groundwater for irrigation use on the certificated acres and use the
groundwater if statutorily outlined conditions apply.
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: 1) non-irrigation grandfathered rights associated with
retired irrigated land; 2) non-irrigation grandfathered rights not associated
with retired irrigated land; and 3) IGFRs. 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 January 1, 1980, for initial AMAs or the date
of the notice of the initiation of designation procedures or the call for the
election for subsequent AMAs, 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
).
A person who holds an IGFR in an initial AMA has the right to annually
withdraw up to 10 acre-feet of groundwater for domestic purposes or stock
watering from a well or wells the holder is using to withdraw groundwater for
irrigation use on the certificated acres, if: 1) as of June 12, 1980,
groundwater withdrawn from the well or wells was being used for domestic
purposes or stock watering; and 2) no certificate of type 2 non-irrigation
grandfathered rights has been issued by the Director of ADWR. Groundwater
withdrawn under these conditions may only be used on the same land and for the
same purpose of which groundwater withdrawn from the well or wells was being
used as of June 12, 1980 (
A.R.S.
� 45-465.03
).
There is no anticipated fiscal impact
to the state General Fund associated with this legislation.
