Section R12-15-722 - Consistency with Management Goal
A. For the Phoenix, Prescott, or Tucson AMAs, the Director shall calculate the volume of groundwater that may be used consistent with the management goal of the AMA in which the proposed use is located for at least 100 years by adding the following:
1. The amount of the groundwater allowance, according to R12-15-724(A), R12-15-726(A), or R12-15-727(A).
2. The amount of any extinguishment credits pledged to the certificate or designation, according to R12-15-724(B), R12-15-726(B), or R12-15-727(B).
3. Any groundwater that is consistent with the achievement of the management goal pursuant to A.R.S. Title 45, Chapter 2.
B. The Director shall determine that a proposed groundwater use in the Phoenix, Prescott, or Tucson AMA is consistent with the management goal of the AMA if the volume calculated in subsection (A) of this Section is equal to or greater than the portion of the applicant's estimated water demand to be met with groundwater.
C. For a certificate in the Pinal AMA, the Director shall calculate the volume of groundwater that may be used consistent with the management goal of the AMA for at least 100 years by adding the following:
1. The amount of the groundwater allowance, according to R12-15-725(A)(1).
2. The amount of any extinguishment credits pledged to the certificate for a grandfathered right that was extinguished on or after January 1, 2019, according to R12-15-725(B), except that annual reported use of such extinguishment credits to make ground-water use consistent with the management goal is limited to the following percentages of groundwater use from the sixth year after certificate issuance:

Years After Certificate Issuance

Percentage of Total Groundwater Use that May Be Made Consistent with the Pinal AMA Management Goal with Extinguishment Credits Pledged to Certificate

Years Six through Ten

75%

Years Eleven through Fifteen

50%

Years Sixteen through Twenty

25%

Years Twenty-one and After

0%

3. The amount of any extinguishment credits pledged to the certificate for a grandfathered right that was extinguished on or after October 1, 2007 and before January 1, 2019.
4. The amount of any extinguishment credits pledged to the certificate for a grandfathered right that was extinguished before October 1, 2007. The Director shall calculate the amount of the extinguishment credits by multiplying the annual amount of the credits by 100.
5. Any groundwater that is consistent with achievement of the management goal pursuant to A.R.S. Title 45, Chapter 2.
D. For a certificate in the Pinal AMA, the Director shall determine that the proposed groundwater use is consistent with the management goal of the AMA if the volume calculated in subsection (C) of this Section is equal to or greater than the portion of the applicant's estimated water demand to be met with groundwater.
E. For a designation in the Pinal AMA, the Director shall calculate the volume of groundwater that may be used consistent with the management goal of the Pinal AMA on an annual basis for at least 100 years by adding the following for each year during the 100-year period:
1. The amount of the groundwater allowance, according to R12-15-725(A)(2). If any of the groundwater allowance is not used during a year, the unused groundwater allowance shall not be added to the volume calculated under this subsection for the following year.
2. The amount of any extinguishment credits pledged to the designation for a grandfathered right that was extinguished on or after January 1, 2019, divided by the number of years remaining in which the credits may be used pursuant to R12-15-725(B). These credits shall be included in the calculation only for those years in which the credits may be used. If any of the extinguishment credits were originally pledged to a certificate and are being used to support the municipal provider's designation pursuant to R12-15-723(G)(2), the extinguishment credits shall not be limited by the percentages in subsection (C)(2) of this section.
3. The amount of any extinguishment credits pledged to the designation for a grandfathered right that was extinguished on or after October 1, 2007 and before January 1, 2019, divided by 100. Extinguishment credits for a grandfathered right that was extinguished on or after October 1, 2007 and before January 1, 2019 may be used in any year.
4. The annual amount of any extinguishment credits pledged to the designation for a grandfathered right that was extinguished before October 1, 2007. The following shall apply if any of the extinguishment credits are not used during a calendar year:
a. If the extinguishment credits were pledged to the designation before October 1, 2007, any extinguishment credits not used during a calendar year shall be added to the volume calculated under this subsection for the following calendar year.
b. If the extinguishment credits are pledged to the designation on or after October 1, 2007, any of the extinguishment credits not used during a calendar year shall not be added to the volume calculated under this subsection for the following calendar year, except that if the extinguishment credits were originally pledged to a certificate before October 1, 2007 and are used to support the municipal provider's designation pursuant to R12-15-723(G)(2), any of the extinguishment credits not used during a calendar year shall be added to the volume calculated under this subsection for the following calendar year.
5. Any groundwater that is consistent with the achievement of the management goal pursuant to A.R.S. Title 45, Chapter 2.
F. For a designation in the Pinal AMA, the Director shall determine that the proposed groundwater use is consistent with the management goal of the Pinal AMA if the volume calculated in subsection (E) of this Section for each year during the 100-year period is equal to or greater than the portion of the applicant's annual estimated water demand to be met with groundwater.
G. Upon application, the following volumes of groundwater used by an applicant are considered consistent with the management goal:
1. If the Director determines that a surface water supply is physically available under R12-15-716 and the volume of the supply actually available during a calendar year is equal to or less than the drought volume for the supply, the volume of groundwater, other than the groundwater that is accounted for under subsection (A), (C), or (E) of this Section, withdrawn within the AMA that, when combined with the available surface water supply, is equal to or less than the drought volume.
2. Any volume of groundwater withdrawn within a portion of an AMA that is exempt from conservation requirements under A.R.S. Title 45 due to waterlogging. The Director shall review the application of this exclusion on a periodic basis, not to exceed 15 years.
3. Remedial groundwater that is consistent with the management goal according to the requirements of R12-15-729.
H. An applicant for a certificate of assured water supply for a dry lot subdivision of 20 lots or fewer is exempt from the requirements of this Section.
