R12-15-107. Municipality Fee

A. Each municipality in this state shall pay a fee to the Department each fiscal year in the amount calculated by the Director pursuant to subsection (B). The fee shall be paid by the dates specified in subsection (E).

B. The Director shall calculate a municipality’s fee for a fiscal year as follows:

1. Determine the total amount of fees the Director will assess and collect from all municipalities during the fiscal year as follows:

a. Determine the maximum total amount of fees the Director may assess and collect from all municipalities during the fiscal year pursuant to A.R.S. § 45-118 consistent with legislative intent. Unless the legislature expresses its intent otherwise in statute or session law, this amount shall be $7,000,000.

b. Reduce the amount determined in subsection (B)(1)(a) by the amount of unobligated monies in the water resources fund at the beginning of the fiscal year, except that:

i. If the Director determines that such a reduction likely would prevent the Department from using all the monies appropriated to it from the water resources fund for the fiscal year, the Director may decrease the amount of the reduction or make no reduction, as appropriate, to allow the Department to use all the monies appropriated to it from the fund.

ii. If the Director determines such a reduction likely would result in an excessive accumulation of unobligated monies in the water resources fund at the end of the fiscal year, the Director may increase the amount of the reduction.

2. Determine the ratio, expressed as a percentage, that the municipality’s population bears to the total population of all municipalities in the state by dividing the municipality’s population by the total population of all municipalities in the state.

3. Multiply the amount from subsection (B)(1) by the percentage calculated in subsection (B)(2). The result is the municipality’s fee for the fiscal year.

C. By July 15 of each fiscal year, the Director shall mail to each municipality a notice of the municipality’s fee for that fiscal year as calculated pursuant to subsection (B), including the manner in which the fee was calculated. The notice shall be mailed to the municipality’s city or town manager or city or town attorney.

D. A municipality may seek review of the calculation of its fee by filing a written request for review with the Director within 15 calendar days after receipt of the initial notice of the fee given by the Director under subsection (C). Review shall be limited to whether the Director’s calculation of the fee contains a mathematical, clerical or typographical error. The Director shall make a final decision on a request for review and mail a final written decision to the municipality requesting the review within 10 calendar days after the date the Director receives the written request. The Director’s final written decision shall state the municipality’s fee following review.

E. A municipality shall pay at least one-half of its fee for a fiscal year by August 15 of that fiscal year and any remaining portion of the fee by January 15 of the fiscal year. If the due date for a payment falls on a weekend, the payment is due on the next business day.

ARTICLE 4. LICENSING TIME-FRAMES

R12-15-401. Licensing Time-frames

The following time-frames apply to licenses issued by the Department. In this Article, “license” has the meaning prescribed in A.R.S. § 41-1001. The licensing time-frames consist of an administrative completeness review time-frame, a substantive review time-frame, and an overall time-frame.

1. Within the administrative completeness review time- frames set forth in subsection (7), the Department shall notify the applicant in writing whether the application is complete or incomplete. If the application is incomplete, the notice shall specify what information or component is required to make the application complete.

2. An applicant with an incomplete application shall supply the missing information within 60 days from the date of the notice, or within such further time as the Director may specify, unless another time limit is specified by statute or applicable rule. If the applicant fails to complete the application within the specified time period, the Director may deny the application. Denial of an application under this provision does not preclude the applicant from filing a new application.

3. Within the overall time-frames set forth in subsection (7), unless extended by mutual agreement under A.R.S. § 41-1075, the Department shall notify the applicant in writing that the application is granted or denied. If the application is denied, the Department shall provide written justification for the denial and a written explanation of the applicant’s right to a hearing or the applicant’s right to appeal.

4. In computing any period of time prescribed by this rule, the day of the filing, notice or event from which the designated period of time begins to run shall not be included. The last day of the computed period shall be included, unless it is a Saturday, Sunday, or a legal holiday, in which event the period runs until the end of the next day which is not a Saturday, Sunday, or legal holiday. When the prescribed administrative completeness review time-frame or substantive review time-frame is less than 11 days, intermediate Saturdays, Sundays and legal holidays shall be excluded from the computation. The overall time-frame is the sum of the administrative completeness review time-frame and the substantive review time-frame calculated as prescribed by this Section.

5. Except as otherwise noted, the licensing time-frames do not include time for hearings. Time-frames in cases where a hearing is held are increased by 120 days.

6. The licensing time-frame rules are effective after December 31, 1998, as prescribed by A.R.S. § 41-1073(A), and apply to all applications filed after that date.

7. The licensing time-frames are set forth in Table A.

Historical Note

Adopted effective December 31, 1998; filed with the Office of the Secretary of State July 28, 1998 (Supp. 98-3). Amended by final rulemaking at 11 A.A.R. 5395, effective February 4, 2006 (Supp. 05-4).

Historical Head

Adopted effective February 7, 1995 (Supp. 95-1). Section repealed; new Section made by final rulemaking at 12 A.A.R. 3475, effective September 12, 2006 (Supp. 06-3).

R12-15-716. Physical Availability

A. The volume of a proposed source of water that is physically available to an applicant for a determination of assured water supply or a determination of adequate water supply is the amount determined by the Director to be physically available pursuant to subsections (B) through (L) of this Section.

B. If the proposed source is groundwater, the applicant shall submit a hydrologic study, using a method of analysis approved by the Director, that accurately describes the hydrology of the affected area. Except as provided in subsection (D) of this Section, the Director shall determine that the proposed volume of groundwater will be physically available for the proposed use if both of the following apply:

1. The groundwater will be withdrawn as follows:

a. Except as provided in subsection (B)(1)(b) of this Section, from wells owned by the applicant or the proposed municipal provider that are located within the service area of the applicant or the proposed municipal provider or from proposed wells that the Director determines are likely to be constructed for future uses of the applicant or the proposed municipal provider.

b. If the application is for a dry lot development, from wells that the Director determines are likely to be constructed on individual lots.

2. Except as provided in subsection (C) of this Section, the groundwater will be withdrawn from depths that do not exceed the applicable maximum 100-year depth-to-static water level according to the following:

Type and location of development

Maximum 100-year depth-to-static water level

a. Developments in Phoenix, Tucson, or Prescott AMAs, except dry lot developments

1000 feet below land
surface

b. Developments in Pinal AMA, except dry lot developments

1100 feet below land
surface

c. Developments outside AMAs, except dry lot developments

1200 feet below land
surface

d. Dry lot developments

400 feet below land
surface

3. The Director shall calculate the projected 100-year depth-to-static water level by adding the following for the area where groundwater withdrawals are proposed to occur:

a. The depth-to-static water level on the date of application.

b. The projected declines caused by existing uses, using the projected decline in the 100-year depth-to-static water level during the 100-year period after the date of application, calculated using records of declines for the maximum period of time for which records are available up to 25 calendar years before the date of application. If evidence is provided to the Director of likely changes in pumpage patterns and aquifer conditions, as opposed to those patterns and conditions occurring historically, the Director may determine projected declines using a model rather than evidence of past declines.

c. The projected decline in the depth-to-static water level during the 100-year period after the date of application, calculated by adding the projected decline from each of the following that are not accounted for in subsection (B)(3)(b) of this Section:

i. The estimated water demand of issued certificates and water reports that will be met with groundwater or stored water recovered outside the area of impact of the stored water, not including the demand of subdivided lots included in abandoned plats;

ii. The estimated water demand of designations that will be met with groundwater or stored water recovered outside the area of impact of the stored water; and

iii. The groundwater reserved for developments for which the Director has issued an analysis pursuant to R12-15-703 or R12-15-712.

d. The projected decline in depth-to-static water level that the Director projects will result from the applicant’s proposed use over a 100-year period.

C. The Director shall lower the maximum 100-year depth-to-static water level requirement specified in subsection (B)(2) of this Section for an applicant seeking a determination of adequate water supply if the applicant demonstrates both of the following:

1. Groundwater is available at the lower depth; and

2. The applicant has the financial capability to obtain the groundwater at the lower depth, according to the criteria in R12-15-720.

D. If the proposed source is groundwater that will be withdrawn from a groundwater basin outside an AMA and transported into an AMA, the Director shall determine that the proposed volume of groundwater will be physically available if both of the following apply:

1. The groundwater will be withdrawn from wells owned by the applicant or the proposed municipal provider or from proposed wells that the Director determines are likely to be constructed for the future uses of the applicant or the proposed municipal provider.

2. Withdrawal of the groundwater will comply with any depth-to-static water level criteria, decline rate criteria, and volume limitation criteria prescribed by statute. If there are no applicable depth-to-static water level criteria prescribed by statute, withdrawal of the groundwater shall comply with the depth-to-static water level criteria in subsection (B)(2) of this Section.

E. Subject to subsection (L) of this Section, if the proposed source of water is surface water, other than CAP water, or Colorado River water, the Director shall determine the annual volume of water that is physically available for the proposed use, taking into consideration the priority date of the right or claim, by calculating 120% of the firm yield of the proposed source at the point of diversion as limited by the capacity of the diversion works; except that if the applicant demonstrates that an alternative source of water will be physically available during times of shortage in the proposed surface water supply, the Director shall determine the annual volume of water available by calculating 100% of the median flow of the proposed source at the point of diversion as limited by the capacity of the diversion works. The Director shall determine the firm yield or median flow as follows:

1. By calculating the firm yield or median flow at the point of diversion based on at least 20 calendar years of flow records from the point of diversion, unless 20 calendar years of records are unavailable and the Director determines that a shorter period of record provides information necessary to determine the firm yield or median flow; or

2. By calculating the firm yield or median flow at the point of diversion using a hydrologic model that projects the firm yield or median flow, taking into account at least 20 calendar years of historic river flows, changes in reservoir storage facilities, and projected changes in water demand. The yield available to any applicant may be composed of rights to stored water, direct diversion, or normal flow rights. If the permit for the water right was issued less than five years before the date of application, the Director shall require the applicant to submit evidence, as applicable, in accordance with this subsection.

F. Subject to subsection (L) of this Section, if the proposed source of water is CAP water, the Director shall determine the annual volume of water that is physically available for the proposed use as follows:

1. If the applicant or the proposed municipal provider has a non-declining, long-term municipal and industrial subcontract for CAP water, calculate 100% of the annual amount of water established in the subcontract.

2. If the applicant has a lease for Indian priority CAP water, calculate 100% of the annual amount of water established in the lease.

3. If the applicant has a subcontract for CAP water other than a non-declining, long-term municipal and industrial subcontract or a lease for Indian priority CAP water:

a. If the applicant submits evidence of sufficient backup water supplies, calculate 100% of the annual amount of water established in the subcontract. The applicant may establish backup water supplies by one or more of the following:

i. A drought response plan;

ii. Long-term storage credits;

iii. A contract for water with a multi-county water conservation district; or

iv. Evidence of other backup supplies that are physically, continuously, and legally available.

b. If the applicant does not submit evidence of sufficient backup water supplies pursuant to subsection (F)(3)(a) of this Section, calculate the percentage of the annual amount of water established in the subcontract that reasonably reflects the reliability of the applicant’s CAP water supply.

G. Subject to subsection (L) of this Section, if the proposed source of water is Colorado River water, the Director shall determine the annual volume of water that is physically available for the proposed use as follows:

1. If the priority of the contract for Colorado River water provides reliability equal to or better than CAP municipal and industrial water, calculate 100% of the annual amount of water established in the contract.

2. If the contract for Colorado River water provides reliability that is less than CAP municipal and industrial water:

a. If the applicant submits evidence of sufficient backup water supplies, calculate 100% of the annual amount of water in the contract. The applicant may establish backup water supplies by one or more of the following:

i. A drought response plan;

ii. Long-term storage credits;

iii. A contract for water with a multi-county water conservation district; or

iv. Evidence of other backup supplies that are physically, continuously, and legally available.

b. If the applicant does not submit evidence of sufficient backup water supplies pursuant to subsection (G)(2)(a) of this Section, calculate the percentage of the annual amount of water established in the contract that reasonably reflects the reliability of the applicant’s Colorado River water supply.

H. Subject to subsection (I) of this Section, if the proposed source of water is effluent, the Director shall determine the annual volume of water that will be physically available by evaluating the current, metered production or the projected production of effluent. The volume of effluent that is physically available shall not include the following:

1. If the effluent will be delivered directly from a wastewater treatment plant, the volume of effluent that exceeds the applicant’s estimated water demand that will be met with effluent; and

2. The volume of effluent that does not comply with any applicable water quality requirements for the proposed use of the effluent.

I. If the proposed source of water is stored water to be recovered from recovery wells, the Director shall determine the volume of water that is physically available for the proposed use as follows:

1. If the stored water is represented by long-term storage credits in existence on the date of application, the amount that is physically available is the amount that may be recovered pursuant to the credits in a manner consistent with A.R.S. Title 45, Chapter 3.1, subject to subsection (I)(3) of this Section.

2. If the applicant proposes to use long-term storage credits that do not exist on the date of application or recover stored water on an annual basis pursuant to A.R.S. § 45-851.01, the Director shall evaluate the following in determining whether to include the proposed credits or the water proposed to be stored and recovered annually in the amount of water that is physically available for the applicant’s proposed use:

a. The terms of a contract to obtain water to store in a storage facility;

b. The physical, continuous, and legal availability of the water proposed to be stored;

c. The presence of an existing storage facility that will be available for use for the proposed storage;

d. The existence of all required permits of an adequate duration; and

e. Whether recovery of the stored water will comply with subsection (I)(3) of this Section.

3. If the applicant proposes to recover the stored water from recovery wells located outside the area of impact of storage, the stored water will be considered physically available only if sufficient water exists for the withdrawals consistent with both of the following:

a. The maximum 100-year depth-to-static water level requirements established in subsection (B)(2) of this Section; and

b. Any criteria for the withdrawals prescribed in the management plan in effect at the time of the application.

J. If the applicant will obtain the source of water through a water exchange agreement, the Director shall determine that the water is physically available for the proposed use if the applicant submits evidence that the source of water the applicant or the applicant’s customers will use will be physically available in accordance with the terms of this Section.

K. In the case of two or more pending, conflicting, complete and correct applications for determinations of assured water supply or determinations of adequate water supply, the Director shall give priority to the application with the earliest priority date. The priority date of an application for a determination of assured water supply or determination of adequate water supply shall be the date that a complete and correct application is filed with the Director. The Director shall consider an application complete and correct if it contains all the information required and the Director verifies that the information is accurate.

L. For a certificate applicant that proposes to use surface water, the Director shall determine that the proposed source is physically available only if the applicant demonstrates one of the following:

1. The land that is the subject of the application is a member land of the CAGRD.

2. The applicant has independently obtained the surface water supply.

2. If the application is for a designation and the applicant provided water to its customers prior to February 7, 1995, multiply 7.5 by the total volume of water provided by the applicant to its customers from any source during calendar year 1994, consistent with the municipal conservation requirements established for the applicant pursuant to Section 5-103(A)(1) of the Second Management Plan for the Phoenix AMA.

3. If the application is for a designation and the applicant commenced providing water to its customers on or after February 7, 1995, the applicant’s groundwater allowance is zero acre-feet.

4. For each calendar year of a designation, the Director shall calculate the volume of incidental recharge for a designated provider within the Phoenix AMA and add that volume to the designated provider’s groundwater allowance. The Director shall calculate the volume of incidental recharge by multiplying the provider’s total water use from any source in the previous calendar year by the standard incidental recharge factor of 4%. A designated provider may apply for a variance from the standard incidental recharge factor as provided in A.R.S. § 45-566.01(E)(1). The Director may establish a different incidental recharge factor for the designated provider if the provider demonstrates to the satisfaction of the Director that the ratio of the average annual amount of incidental recharge expected to be attributable to the provider during the management period, to the average amount of water expected to be withdrawn, diverted, or received for delivery by the provider for use within its service area during the management period, is different than 4%.

B. The Director shall calculate the extinguishment credits for the extinguishment of a grandfathered right in the Phoenix AMA as follows:

1. For the extinguishment of a type 2 non-irrigation grandfathered right, multiply the number of acre-feet indicated on the certificate by the difference between 2025 and the calendar year of extinguishment.

2. For the extinguishment of all or part of an irrigation grandfathered right, or all or part of a type 1 non-irrigation grandfathered right, multiply 1.5 acre-feet per acre by the number of irrigation acres associated with the extinguished irrigation grandfathered right or the number of acres to which the extinguished type 1 non-irrigation grandfathered right is appurtenant, and then multiply the product by the difference between 2025 and the calendar year of extinguishment, except that:

a. If only a portion of an irrigation grandfathered right or a type 1 non-irrigation grandfathered right is extinguished, the Director shall include in the calculation only those acres associated with the portion of the right that is extinguished; and

b. If an extinguished irrigation grandfathered right has a debit balance in the corresponding flexibility account established under A.R.S. § 45-467, the Director shall subtract the amount of the debit from the amount of the extinguishment.

a. If the applicant was designated as having an assured water supply as of October 1, 2007:

i. Multiply the applicant’s service area population as of October 1, 2007 by 125 gallons per capita per day and multiply the product by 365 days. The service area population shall be determined using the methodology set forth in Section 5-103(D) of the Third Management Plan for the Pinal AMA.

ii. Convert the number of gallons determined in subsection (A)(2)(a)(i) into acre-feet by dividing the number by 325,851 gallons.

iii. Determine the number of residential lots within plats that were recorded as of October 1, 2007 but not served water as of that date, and to which the applicant commenced water service by January 1, 2010.

iv. Multiply the number of lots determined in subsection (A)(2)(a)(iii) of this Section by 0.35 acre-foot per lot.

v. Add the volume from subsection (A)(2)(a)(ii) of this Section and the volume from subsection (A)(2)(a)(iv) of this Section.

b. If the applicant provided water to its customers before October 1, 2007 but was not designated as having an assured water supply as of that date, and a complete and correct application for designation is filed before January 1, 2012, multiply the applicant’s service area population as of October 1, 2007 by 125 gallons per capita per day and multiply the product by 365 days. The service area population shall be determined using the methodology in Section 5-103(D) of the Third Management Plan for the Pinal AMA.

c. If the applicant provided water to its customers before October 1, 2007 but was not designated as having an assured water supply as of that date, and a complete and correct application for designation is filed on or after January 1, 2012, the applicant’s groundwater allowance is zero acre-feet.

d. If the applicant commenced providing water to its customers on or after October 1, 2007, the applicant’s groundwater allowance is zero acre-feet.

3. For each calendar year of a designation, the Director shall calculate the volume of incidental recharge for a designated provider within the Pinal AMA and add that volume to the designated provider’s groundwater allowance. The Director shall calculate the volume of incidental recharge by multiplying the provider’s total water use from any source in the previous calendar year by the standard incidental recharge factor of 4%. A designated provider may apply for a variance from the standard incidental recharge factor by submitting a hydrologic study demonstrating, to the satisfaction of the Director, that the ratio of the average annual amount of incidental recharge expected to be attributable to the designated provider during the management period to the average annual amount of water expected to be withdrawn, diverted or received for delivery by the designated provider for use within its service area during the management period is different than 4%. The hydrologic study shall include the amount of water withdrawn, diverted or received for delivery by the designated provider for use within its service area during each of the preceding five years and the amount of incidental recharge that was attributable to the designated provider during each of those years. The Director may establish a different incidental recharge factor for the designated provider upon such demonstration.

R12-15-726. Prescott AMA Calculation of Groundwater Allowance and Extinguishment Credits

A. The Director shall calculate the groundwater allowance for a certificate or designation in the Prescott AMA as follows:

1. If the application is for a certificate of assured water supply, the Director shall:

a. Subtract the year of application from 2025,

b. Multiply the number determined in subsection (A)(1)(a) by the applicant’s annual estimated water demand, and

c. Divide that product by two. The minimum volume that may be calculated in this subsection is zero acre-feet.

2. If the application is for a designation of assured water supply:

a. Except as provided in subsections (A)(3) and (A)(5), if the applicant was in existence as of January 12, 1999, and the application is filed before calendar year 2026, the Director shall:

i. Multiply by 100 the largest volume of groundwater determined by the Director to have been withdrawn by the applicant from within the Prescott AMA for use within the applicant’s service area in any calendar year from 1995 through 1998, consistent with the municipal conservation requirements applicable under the second management plan for the Prescott active management area;

ii. Determine the volume of the applicant’s total water demand, from any source, for 1999, consistent with the municipal conservation requirements established for the applicant in the management plan in effect on the date of application;

iii. Determine the volume of the applicant’s total water demand, from any source, for 2014, consistent with the municipal conservation requirements established for the applicant in the management plan in effect on the date of application;

iv. Subtract the volume calculated in subsection (A)(2)(a)(ii) from the volume calculated in subsection (A)(2)(a)(iii) and then multiply the difference by 26;

v. Divide the product obtained in subsection (A)(2)(a)(iv) by two;

vi. If any residential groundwater uses, including residential groundwater uses served by an exempt well, in existence on August 21, 1998, have been replaced by permanent water service from the applicant after August 21, 1998, multiply one-half acre-foot of groundwater by the number of housing units receiving the service and then multiply that product by 100;

vii. Determine the volume of groundwater withdrawn by the applicant from within the Prescott active management area during the period beginning January 1, 1999, and ending December 31 of the calendar year before the date of the application;

viii. Multiply the volume of groundwater withdrawn by the applicant from within the Prescott active management area in 1999 by the number of calendar years in the period beginning with 1999 and ending with the calendar year before the date of application;

ix. Subtract from the volume calculated in subsection (A)(2)(a)(vii) the volume calculated in subsection (A)(2)(a)(viii). The volume calculated in this subsection shall not be less than zero; and

x. Add the volumes calculated in subsections (A)(2)(a)(i), (A)(2)(a)(v), and (A)(2)(a)(vi), and then subtract from the sum the volume calculated in subsection (A)(2)(a)(ix).

b. If the applicant did not exist as of January 12, 1999, or the date of application occurs after calendar year 2025, the groundwater allowance is zero acre-feet, except that if any residential groundwater uses, including residential groundwater uses served by an exempt well, in existence on August 21, 1998, have been replaced by permanent water service from the applicant after August 21, 1998, the groundwater allowance is a volume of groundwater computed by multiplying one-half acre-foot of groundwater by the number of housing units receiving the service and multiplying that product by 100.

3. For the purpose of determining the groundwater allowance under subsection (A)(2)(a), at the request of the applicant, the Director shall replace the volume of groundwater calculated in subsection (A)(2)(a)(ii) through (v) with the amount of groundwater necessary for the applicant to serve the residential lots described in subsection (A)(4):

a. To compute this amount of groundwater, the Director shall:

i. Determine the average dwelling occupancy within the applicant’s service area and multiply that average occupancy by an amount of groundwater, calculated by multiplying 150 gallons per capita per day by 365 days; and

ii. Multiply the product in subsection (A)(3)(a)(i) by the number of residential lots described in subsection (A)(4), and then multiply that product by 100.

b. The Director shall not include the amount computed in subsection (A)(3)(a) within the amount of groundwater that the applicant may use under subsection (A)(2)(a) until a final plat for the lots has been recorded.

4. The Director shall include residential lots that will be served by the applicant in the calculation made under subsection (A)(3) if the lots meet all of the following criteria:

a. A preliminary plat for the lots was submitted to the city, town, or county on or before August 21, 1998, and the final plat is subsequently recorded;

b. The lots were not being served water on or before August 21, 1998; and

c. Any one of the following applies:

i. The lots were included within an application for certificate of assured water supply that was filed before August 21, 1998, the Director determined that the application was complete and correct as of August 21, 1998, and the Director subsequently issued a certificate of assured water supply for the lots.

ii. A preliminary plat for the lots was approved by a city, town, or county on or before August 21, 1998. At the time the preliminary plat was approved, the subdivider of the lots obtained a written commitment of water service from a municipal provider that was designated as having an assured water supply and the provider demonstrated to the satisfaction of the Director that sufficient water is physically available to serve the lots under the criteria in R12-15-716.

5. For the purpose of determining the groundwater allowance under subsection (A)(2)(a), if the applicant makes the request described in subsection (A)(3), the Director shall replace the volume of groundwater calculated in subsection (A)(2)(a)(viii) with an amount of groundwater calculated as follows. The Director shall:

a. Determine the number of calendar years in the period beginning with 1999 and ending with the calendar year before the date of application and multiply that number of years by the largest volume of groundwater determined by the Director to have been withdrawn by the applicant from within the Prescott active management area for use within the applicant’s service area in any calendar year from 1995 through 1998, consistent with the municipal conservation requirements applicable under the second management plan for the Prescott active management area;

b. Determine the average dwelling occupancy within the applicant’s service area and multiply that average dwelling occupancy by an amount of groundwater calculated by multiplying 150 gallons per capita per day by 365 days;

c. For each year in the period beginning with 1999 and ending with the calendar year before the date of application, determine the number of the residential lots that meet the criteria in subsection (A)(4) and were served water by the applicant as of July 1 of the relevant year and add the number of these residential lots determined for each year;

d. Multiply the volume of groundwater calculated in subsection (A)(5)(b) by the number of residential lots in subsection (A)(5)(c); and

e. Add the volumes of groundwater from subsections (A)(5)(a) and (A)(5)(d).

B. The Director shall calculate the extinguishment credits for extinguishing a grandfathered right in the Prescott AMA as follows:

1. For the extinguishment of a type 2 non-irrigation grandfathered right, multiply the number of acre-feet indicated on the certificate by the difference between 2025 and the calendar year of extinguishment.

2. For the extinguishment of an irrigation grandfathered right or a type 1 non-irrigation grandfathered right:

a. Through December 31, 2010:

i. If the irrigation acres associated with the extinguished right were irrigated for at least four of the six calendar years preceding January 1, 2000, multiply 1.5 acre-feet per acre by the number of irrigation acres associated with the extinguished right or the number of acres to which the extinguished right is appurtenant and multiply that product by 25.

ii. If the irrigation acres associated with the extinguished right were not irrigated for at least four of the six calendar years preceding January 1, 2000, multiply 1.5 acre-feet per acre by the number of irrigation acres associated with the extinguished right or the number of acres to which the extinguished right is appurtenant and multiply the product by the difference between 2025 and the year in which the statement of intent to extinguish is filed.

b. After December 31, 2010, multiply 1.5 acre-feet per acre by the number of irrigation acres associated with the extinguished right or the number of acres to which the extinguished right is appurtenant and multiply the product by the difference between 2025 and the year in which the statement of intent to extinguish is filed.

2. If the application is for a designation and the applicant provided water to its customers before February 7, 1995, multiply 15 by the total volume of water provided by the applicant to its customers from any source during calendar year 1994, consistent with the municipal conservation requirements established for the applicant pursuant to Section 5-103(A)(1) of the Second Management Plan for the Tucson AMA.

3. If the application is for a designation and the applicant commenced providing water to its customers on or after February 7, 1995, the applicant’s groundwater allowance is zero acre-feet.

4. For each calendar year of the designation, the Director shall calculate the volume of incidental recharge for a designated provider within the Tucson AMA and add that volume to the designated provider’s groundwater allowance. The Director shall calculate the volume of incidental recharge by multiplying the provider’s total water use from any source in the previous calendar year by the standard incidental recharge factor of 4%. A designated provider may apply for a variance from the standard incidental recharge factor as provided in A.R.S. § 45-566.01(E)(1). The Director may establish a different incidental recharge factor for the designated provider if the provider demonstrates to the satisfaction of the Director that the ratio of the average annual amount of incidental recharge expected to be attributable to the provider during the management period, to the average amount of water expected to be withdrawn, diverted, or received for delivery by the provider for use within its service area during the management period, is different than 4%.

B. The Director shall calculate the extinguishment credits for the extinguishment of a grandfathered right in the Tucson AMA as follows:

1. For the extinguishment of a type 2 non-irrigation grandfathered right, multiply the number of acre-feet indicated on the certificate by the difference between 2025 and the calendar year of extinguishment.

2. For the extinguishment of all or part of an irrigation grandfathered right, or all or part of a type 1 non-irrigation grandfathered right, multiply 1.5 acre-feet per acre by the number of irrigation acres associated with the extinguished irrigation grandfathered right or the number of acres to which the extinguished type 1 non-irrigation grandfathered right is appurtenant, and then multiply the product by the difference between 2025 and the calendar year of extinguishment, except that:

a. If only a portion of an irrigation grandfathered right or a type 1 non-irrigation grandfathered right is extinguished, the Director shall include in the calculation only those acres associated with the portion of the right that is extinguished; and

b. If an extinguished irrigation grandfathered right has a debit balance in the corresponding flexibility account established under A.R.S. § 45-467, the Director shall subtract the amount of the debit from the amount of the extinguishment.

R12-15-729. Remedial Groundwater; Consistency with Management Goal

A. Use of remedial groundwater by a municipal provider before January 1, 2025, is deemed consistent with the management goal of the AMA in which the remedial groundwater is withdrawn and is excluded when determining compliance with management goal requirements in this Article if all of the following apply:

1. The Director determines that the remedial groundwater use is consistent with the management goal under subsection (F) or (H) of this Section or the remedial groundwater use is consistent with the management goal under subsection (J) of this Section; and

2. The municipal provider complies with the metering and reporting requirements in subsection (K) of this Section.

B. A municipal provider that is using remedial groundwater or that has agreed in a consent decree or other document approved by ADEQ or the EPA to use remedial groundwater may apply to the Director for a determination that the municipal provider’s use of the remedial groundwater is consistent with the management goal of the active management area by submitting an application on a form provided by the Director with the information required in subsection (D) of this Section before January 1, 2010.

C. A municipal provider filing an application under subsection (B) of this Section for remedial groundwater use associated with a treatment plant in operation before June 15, 1999, may request an increase in the project’s annual authorized volume at the time the application is filed. The Director shall grant the request and increase the annual authorized volume up to the maximum treatment capacity of the treatment plant if the municipal provider submits evidence that an increase in the annual authorized volume is necessary to further the purpose of the remedial action project and that the increase is not in violation of the consent decree or other document approved by ADEQ or the EPA for the remedial action project.

D. An applicant shall provide the following with an application submitted under subsection (B) of this Section:

1. A document evidencing ADEQ’s or EPA’s approval of the municipal provider’s withdrawal and use of remedial groundwater, such as a remedial action plan, record of decision, or consent decree;

2. The volume of remedial groundwater that will be withdrawn and used annually by the municipal provider and the purpose for which the remedial groundwater will be used;

3. The time period during which the remedial groundwater will be withdrawn and used by the municipal provider;

4. A reference to the annual authorized volume provided in the document submitted pursuant to subsection (D)(1) of this Section or, if the document submitted pursuant to subsection (D)(1) does not specify the annual authorized volume for the project, the annual authorized volume claimed by the municipal provider and a written justification for that volume;

5. If the approved remedial action project is currently operating, the volume of remedial groundwater withdrawn pursuant to the project for each year before the year in which the application is filed;

6. The designated provider or certificate to which the remedial groundwater will be pledged;

7. If the municipal provider is requesting an increase in the annual authorized volume of the project pursuant to subsection (C) of this Section, evidence that the increase is necessary to further the purpose of the remedial action project and that the increase is not in violation of the consent decree or other document approved by ADEQ or the EPA for the project;

8. The name and telephone number of a person the Department may contact regarding the application; and

9. Any other information reasonably required to assist the Director in making the determination under subsection (F) of this Section.

E. After receiving an application under subsection (B) of this Section, the Director shall determine that the application is complete and correct if it contains all the information required in subsection (D) of this Section and the Director verifies that the information is accurate. If the Director determines that the application is complete and correct, the Director shall assign a priority date to the application according to the following:

1. If the Director determines that the application was complete and correct when filed, the priority date of the application is the date the application was filed.

2. If the Director determines that the application was not complete or correct when filed because of minor deficiencies, the Director shall notify the applicant of the deficiencies in writing and give the applicant 30 days to correct the deficiencies. If the applicant submits the necessary information to correct the deficiencies within 30 days after the date of the notice, the priority date of the application is the date the application was filed.

3. If the Director determines that the application was not complete or correct when filed and that the deficiencies are not minor, the Director shall notify the applicant of the deficiencies and give the applicant at least 60 days to submit the necessary information to correct the deficiencies.

F. The Director shall approve a complete and correct application filed under subsection (B) of this Section if the Director determines that the applicant will use remedial groundwater before January 1, 2025. If the Director approves a municipal provider’s application, the Director shall calculate the annual amount of remedial groundwater use that is deemed consistent with the management goal of the AMA as follows:

1. The Director shall determine the total annual amount of remedial groundwater use in all AMAs that is deemed to be consistent with the management goal under this subsection and subsections (H) and (I) of this Section for applications with a priority date earlier than the priority date of the municipal provider’s application.

2. If the amount determined in subsection (F)(1) of this Section is less than 65,000 acre-feet and the difference between those amounts is equal to or greater than the municipal provider’s authorized remedial groundwater use during the year, the amount of remedial groundwater use by the municipal provider that is deemed to be consistent with the management goal during the year is the amount of the municipal provider’s authorized remedial groundwater use during the year.

3. If the amount determined in subsection (F)(1) of this Section is less than 65,000 acre-feet and the difference between those amounts is less than the municipal provider’s authorized remedial groundwater use during the year, the amount of remedial groundwater use by the municipal provider that is deemed consistent with the management goal during the year is the amount of the municipal provider’s authorized remedial groundwater use during the year up to the difference between the amount determined in subsection (F)(1) and 65,000 acre-feet, plus a percentage of the municipal provider’s authorized remedial groundwater use during the year that exceeds the difference. The percentage is 50 percent for calendar years 2000 through 2009, 25 percent for calendar years 2010 through 2019, and 10 percent for calendar years 2020 through 2024.

4. If the amount determined in subsection (F)(1) of this Section is equal to or greater than 65,000 acre-feet, the amount of remedial groundwater use by the municipal provider that is deemed consistent with the management goal during the year is a percentage of the municipal provider’s authorized remedial groundwater use during the year. The percentage is 50 percent for calendar years 2000 through 2009, 25 percent for calendar years 2010 through 2019, and 10 percent for calendar years 2020 through 2024.

G. If the Director determines that remedial groundwater use by a municipal provider is consistent with the management goal of the active management area under subsection (F) of this Section, the determination shall apply to remedial groundwater used by the municipal provider between the priority date of the application and January 1, 2025.

H. If, before the effective date of this Section, a municipal provider filed an application with the Director requesting that the Director determine that the provider’s use of remedial groundwater pursuant to an approved remedial action project is consistent with the management goal of the active management area under Laws 1997, Ch. 287, § 52, as amended by Laws 1999, Ch. 295, § 50, the following shall apply:

1. If the Director approved the application before the effective date of this Section and determined the annual amount of remedial groundwater use by the applicant that will be considered consistent with the management goal, the Director’s determination shall apply after the effective date of this Section and the Director shall include the annual amount of remedial groundwater use determined by the Director to be consistent with the management goal in the total amount of remedial groundwater determined in subsection (F)(1) of this Section.

2. If the Director did not approve the application before the effective date of this Section, the Director shall process the application under subsections (E) and (F) of this Section. If the Director approves the application, the Director’s determination shall apply to remedial groundwater withdrawn and used by the municipal provider pursuant to the approved remedial action project from the priority date of the application until January 1, 2025.

I. A municipal provider that is using remedial groundwater that has been determined by the Director to be consistent with the management goal under subsection (F) or (H) of this Section may apply to the Director for an increase in the annual authorized volume of the approved remedial action project as follows:

1. The applicant shall submit an application on a form provided by the Director.

2. The Director shall determine that the application is complete and correct if it contains all of the required information and the Director verifies that the information is accurate.

3. If the Director determines that an application filed under this subsection is complete and correct, the Director shall assign a priority date to the application using the criteria in subsection (E) of this Section.

4. The Director shall approve the application if the municipal provider submits information that demonstrates one of the following:

a. The annual authorized volume of the approved remedial action project has been increased in a consent decree or other document approved by ADEQ or the EPA; or

b. An increase is necessary to further the purpose of the approved remedial action project, and the increase is not in violation of the consent decree or other document approved by ADEQ or the EPA for the project.

5. If the Director approves the application, the Director shall determine the additional annual amount of remedial groundwater use by the municipal provider that is deemed consistent with the management goal of the active management area, using the criteria in subsections (F) and (G) of this Section. The Director shall include the annual amount of remedial groundwater use determined by the Director to be consistent with the management goal under this subsection in the total amount of remedial groundwater determined in subsection (F)(1) of this Section.

J. Until January 1, 2025, use of remedial groundwater by a municipal provider during a year is deemed consistent with the management goal of the AMA in which the remedial groundwater was withdrawn without approval of the Director under subsection (F) or (H) of this Section if:

1. The total annual amount of remedial groundwater withdrawn from all wells pursuant to the approved remedial action project does not exceed 250 acre-feet; and

2.

1. Prior to January 1 of the year in which the deliveries of tailwater take place, the Director approves a written plan to measure and record the tailwater deliveries. The plan shall include:

a. The installation and use of a totalizing water measuring device that will record tailwater deliveries with no greater than a 10 percent margin of error.

b. Procedures for keeping accurate records of the tailwater deliveries.

c. A description of how the tailwater will be delivered.

d. An identification of the farm or irrigation district to which the tailwater will be delivered.

2. The person has measured, recorded, and delivered the tailwater in accordance with the plan approved under subsection (A)(1) of this Section.

3. The tailwater was delivered directly from the farm on which it originated to:

a. A specified farm that used the tailwater for the legal irrigation of irrigation acres or surface water right acres on that farm, or

b. A specified irrigation district that delivered the tailwater for the legal irrigation of irrigation acres or surface water right acres within that district.

B. A person who delivers tailwater in accordance with subsection (A) of this Section, and a person who directly receives and uses the tailwater pursuant to subsection (A)(3)(a) of this Section, shall account for and report the tailwater as if it were comprised of a mixture of groundwater, decreed and appropriative surface water other than normal flow, central Arizona project water, spillwater, other surface water, and effluent, as applicable, in the same proportions as those types of water comprise the total amount of water other than normal flow received or withdrawn for irrigation use during the calendar year on the farm on which the tailwater originated.

C. A person who uses tailwater that has not been delivered and accounted for as provided in subsections (A) and (B) of this Section may credit against the person’s use of groundwater in a calendar year the amount of the tailwater used during the calendar year if the use of such tailwater would cause a debit to be incurred. The credit shall be applied only against the person’s operating flexibility account debits that otherwise would have been incurred that year and shall not be used to discharge debits from prior years or accumulate credits for future years. For purposes of calculating credits to the person’s operating flexibility account, the Director shall treat tailwater as groundwater, unless reported otherwise according to its source.

D. An irrigation district that receives tailwater pursuant to subsection (A)(3)(b) shall account for the water in the same manner as other water in the district’s distribution system.

The owner of a high or significant hazard potential dam shall provide timely warning to the Department and all other persons listed in the emergency action plan of problems at the dam. The owner shall develop and maintain effective emergency action plans and coordinate those plans with local officials as prescribed in R12-15-1221.

B. The owner shall conduct frequent observation of the dam, as prescribed in the emergency action plan and as follows:

1. The owner shall increase the frequency of observation when the reservoir is full, during heavy rains or flooding, and following an earthquake.

2. The owner shall report to the Director any condition that threatens the safety of the dam as prescribed in R12-15-1224(A). The owner shall make the report as soon as possible, but not later than 12 hours after discovery of the conditions.

3. If dam failure appears imminent, the owner shall notify the county sheriff or other emergency official immediately.

4. The owner is responsible for the safety of the dam and shall take action to lower the reservoir if it appears that the dam has weakened or is in danger of failing.

C. The owner of a dam shall install, maintain, and monitor instrumentation to evaluate the performance of the dam. The Director shall require site-specific instrumentation that the Director deems necessary for monitoring the safety of the dam when failure may endanger human life and property. Conditions that may require monitoring include land subsidence, earth fissures, embankment cracking, phreatic surface, seepage, and embankment movements.

R12-15-1206. Classification of Dams

A. Size Classification. Dams are classified by size as small, intermediate, or large. Size is determined with reference to Table 2. An owner or engineer shall determine size by storage capacity or height, whichever results in the larger size.

B. Hazard Potential Classification

1. The Department shall base hazard potential classification on an evaluation of the probable present and future incremental adverse consequences that would result from the release of water or stored contents due to failure or improper operation of the dam or appurtenances, regardless of the condition of the dam. The evaluation shall include land use zoning and development projected for the affected area over the 10 year period following classification of the dam. The Department considers all of the following factors in hazard potential classification: probable loss of human life, economic and lifeline losses, and intangible losses identified and evaluated by a public resource management or protection agency.

a. The Department bases the probable incremental loss of human life determination primarily on the number of permanent structures for human habitation that would be impacted in the event of failure or improper operation of a dam. The Department considers loss of human life unlikely if:

i. Persons are only temporarily in the potential inundation area;

ii. There are no residences or overnight campsites; and

iii. The owner has control of access to the potential inundation area and provides an emergency action plan with a process for warning in the event of a dam failure or improper operation of a dam.

b. The Department bases the probable economic, lifeline, and intangible loss determinations on the property losses, interruptions of services, and intangible losses that would be likely to result from failure or improper operation of a dam.

2. The 4 hazard potential classification levels are very low, low, significant, and high, listed in order of increasing probable adverse incremental consequences, as prescribed in Table 3. The Director shall classify intangible losses by considering the common or unique nature of features or habitats and temporary or permanent nature of changes.

a. Very Low Hazard Potential. Failure or improper operation of a dam would be unlikely to result in loss of human life and would produce no lifeline losses and very low economic and intangible losses. Losses would be limited to the 100 year floodplain or property owned or controlled by the dam owner under long-term lease. The Department considers loss of life unlikely because there are no residences or overnight camp sites.

b. Low Hazard Potential. Failure or improper operation of a dam would be unlikely to result in loss of human life, but would produce low economic and intangible losses, and result in no disruption of lifeline services that require more than cosmetic repair. Property losses would be limited to rural or agricultural property, including equipment, and isolated buildings.

c. Significant Hazard Potential. Failure or improper operation of a dam would be unlikely to result in loss of human life but may cause significant or high economic loss, intangible damage requiring major mitigation, and disruption or impact on lifeline facilities. Property losses would occur in a predominantly rural or agricultural area with a transient population but significant infrastructure.

d. High Hazard Potential. Failure or improper operation of a dam would be likely to cause loss of human life because of residential, commercial, or industrial development. Intangible losses may be major and potentially impossible to mitigate, critical lifeline services may be significantly disrupted, and property losses may be extensive.

3. An applicant shall demonstrate the hazard potential classification of a dam before filing an application to construct. The Department shall review the applicant’s demonstration early in the design process at pre-application meetings prescribed in R12-15-1207(D).

4. The Department shall review the hazard potential classification of each dam during each subsequent dam safety inspection and revise the classification in accordance with current conditions.

R12-15-1216. Design of a High, Significant, or Low Hazard Potential Dam

A. General Requirements.

1. Emergency Spillway Requirements. An applicant shall:

a. Construct each spillway in a manner that avoids flooding in excess of the flooding that would have occurred in the same location under the same conditions before construction. The owner of a dam shall demonstrate that a spillway discharge would not result in incremental adverse consequences. In determining whether a spillway discharge of a dam would result in incremental adverse consequences, the Director shall evaluate whether the owner has taken any or all of the following actions: issuing public notice to downstream property owners, complying with flood insurance requirements, adopting emergency action plans, conducting mock flood drills, acquiring flow easements or other acquisitions of real property, or other actions appropriate to safeguard the dam site and flood channel.

b. Include a control structure to avoid head cutting and lowering of the spillway crest for spillways excavated in soils or soft rock. In the alternative, the design may provide evidence acceptable to the Director that erosion during the inflow design flood will not result in a sudden release of the reservoir.

c. Provide each spillway and channel with a minimum width of 10 feet and suitable armor to prevent erosion during the discharge resulting from the inflow design flood.

d. Ensure that downstream spillway channel flows do not encroach on the dam unless suitable erosion protection is constructed.

e. Ensure that each spillway, in combination with outlets, is able to safely pass the peak discharge flow rate, as calculated on the basis of the inflow design flood.

f. Not construct bridges or fences across a spillway unless the construction is approved in writing by the Director. The Director’s approval may include conditions regarding the design and operation of the spillway and fencing, based on safety concerns.

g. Not use a pipe or culvert as an emergency spillway unless the Director approves the use following review of the dam design and site characteristics.

A. The director shall not approve an application for a permit to construct a new well or a replacement well in a new location under A.R.S. § 45-599 if the director determines that the withdrawals from the proposed well or wells will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells under subsection (B) of this Section.

B. The director shall determine that the withdrawals from the proposed well or wells will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells if any of the following apply:

1. Except as provided in subsection (D) of this Section, the director determines that the probable impact of the withdrawals from the proposed well or wells on any well of record in existence as of the date of receipt of the application will exceed 10 feet of additional drawdown after the first five years of operation of the proposed well or wells. To assist the director in making a determination under this subsection, the applicant may submit a hydrological study delineating those areas surrounding the proposed well or wells in which the projected impacts on water levels will exceed 10 feet of additional drawdown after the first five years of operation of the proposed well or wells. The director may require the applicant to submit such a hydrological study if the director determines that the study will assist the director in making a determination under this subsection;

2. The director determines that the proposed well or wells will be located in an area of known land subsidence and the withdrawals from the proposed well or wells will likely cause unreasonably increasing damage from additional regional land subsidence. To assist the director in making a determination under this subsection, the applicant may submit a hydrological study, which may include a geophysical evaluation, demonstrating the impact of the withdrawals from the proposed well or wells on regional land subsidence. The director may require the applicant to submit such a hydrological study if the director determines that the study will assist the director in making a determination under this subsection; or

3. Except as provided in subsection (E) of this Section, the director determines, after consulting with ADEQ, that withdrawals from the proposed well or wells will likely cause the migration of contaminated groundwater from a remedial action site to a well of record in existence as of the date of the receipt of the application, resulting in a degradation of the quality of the water withdrawn from the well of record so that the water will no longer be usable for the purpose for which it is currently being used without additional treatment, and that the damage to the owner of the well of record will not be prevented or adequately mitigated through the implementation of a program regulated under Title 49 of the Arizona Revised Statutes, or a program regulated by EPA or DOD. To assist the director in making a determination under this subsection, the applicant may submit a hydrological study demonstrating whether the withdrawals from the proposed well or wells will have the effect described in this subsection. The director may require the applicant to submit such a hydrological study if the director determines that the study will assist the director in making a determination under this subsection.

C. In making a determination under subsection (B)(1), (B)(2), or (B)(3) of this Section, if the proposed well is a replacement well in a new location, the director shall take into account the collective effects of reducing or terminating withdrawals from the well being replaced combined with the proposed withdrawals from the replacement well if the applicant submits a hydrological study demonstrating those collective effects to the satisfaction of the director.

D. If the director determines under subsection (B)(1) of this Section that the probable impact of the withdrawals from the proposed well or wells on one or more wells of record in existence as of the date of receipt of the application will exceed 10 feet of additional drawdown after the first five years of operation of the proposed well or wells, the director shall notify the applicant in writing of the location of the wells of record and the names and addresses of the owners of the wells as shown in the Department’s well registry. The director shall not determine that the withdrawals from the proposed well or wells will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells under subsection (B)(1) of this Section if within 60 days after the date on the notice, or a longer time period approved by the director, the applicant submits one of the following for each well of record identified in the notice:

1. A signed and notarized consent form from the owner of the well of record consenting to the withdrawals from the proposed well or wells. The applicant shall use the consent form furnished by the director; or

2. Evidence satisfactory to the director that the address of the owner of the well of record as shown in the Department’s well registry records is inaccurate and that the applicant made a reasonable attempt to locate the current owner of the well of record but was unable to do so.

E. If the director determines that withdrawals from the proposed well or wells will have the effect described in subsection (B)(3) of this Section on one or more wells of record in existence as of the date of receipt of the application, the director shall notify the applicant in writing of the location of the wells of record and the names and addresses of the owners of the wells as shown in the Department’s well registry. The director shall not determine that the withdrawals from the proposed well or wells will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells under subsection (B)(3) of this Section if within 60 days after the date on the notice, or a longer time period approved by the director, the applicant submits one of the following for each well of record identified in the notice:

1. A signed and notarized consent form from the owner of the well of record consenting to the withdrawals from the proposed well or wells. The applicant shall use the consent form furnished by the director; or

2. Evidence satisfactory to the director that the address of the owner of the well of record as shown in the Department’s well registry records is inaccurate and that the applicant made a reasonable attempt to locate the current owner of the well of record but was unable to do so.

F. At any time before a final determination under this Section, the applicant may:

1. Amend the application to change the location of the proposed well or wells or the amount of groundwater to be withdrawn from the proposed well or wells to lessen the degree of impact on wells of record or regional land subsidence; or

2. Agree to construct or operate the proposed well or wells in a manner that lessens the degree of impact on wells of record or regional land subsidence. The director shall indicate in the well permit that compliance with the agreement is a condition of the well permit.

R12-15-1305. Well Spacing Requirements - Applications to Use a Well to Withdraw Groundwater for Transportation to an Active Management Area Under A.R.S. § 45-559

A. The director shall not approve an application to use a well or wells constructed after September 21, 1991, to withdraw groundwater for transportation to an active management area under A.R.S. § 45-559 if the director determines that the withdrawals for that purpose will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells under subsection (B) of this Section.

B. The director shall determine that the withdrawals of groundwater will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells if any of the following apply:

1. Except as provided in subsection (C) of this Section, the director determines that the probable impact of the groundwater withdrawals on any well of record in existence as of the date of receipt of the application will exceed 10 feet of additional drawdown after the first five years of the withdrawals. To assist the director in making a determination under this subsection, the applicant may submit a hydrological study delineating those areas surrounding the proposed well or wells in which the projected impacts of the groundwater withdrawals on water levels will exceed 10 feet of additional drawdown after the first five years of the withdrawals. The director may require the applicant to submit such a hydrological study if the director determines that the study will assist the director in making a determination under this subsection;

2. The director determines that the proposed well or wells will be located in an area of known land subsidence and the groundwater withdrawals will likely cause unreasonably increasing damage from additional regional land subsidence. To assist the director in making a determination under this subsection, the applicant may submit a hydrological study, which may include a geophysical evaluation, demonstrating the impact of the groundwater withdrawals on regional land subsidence. The director may require the applicant to submit such a hydrological study if the director determines that the study will assist the director in making a determination under this subsection; or

3. Except as provided in subsection (D) of this Section, the director determines, after consulting with ADEQ, that the groundwater withdrawals will likely cause the migration of contaminated groundwater from a remedial action site to a well of record in existence as of the date of receipt of the application, resulting in a degradation of the quality of the water withdrawn from the well of record so that the water will no longer be usable for the purpose for which it is currently being used without additional treatment, and that the damage to the owner of the well of record will not be prevented or adequately mitigated through the implementation of a program regulated under Title 49 of the Arizona Revised Statutes, or a program regulated by EPA or DOD. To assist the director in making a determination under this subsection, the applicant may submit a hydrological study demonstrating whether the groundwater withdrawals will have the effect described in this subsection. The director may require the applicant to submit such a hydrological study if the director determines that the study will assist the director in making a determination under this subsection.

C. If the director determines under subsection (B)(1) of this Section that the probable impact of the groundwater withdrawals on any well of record in existence as of the date of receipt of the application will exceed 10 feet of additional drawdown after the first five years of the withdrawals, the director shall notify the applicant in writing of the location of the wells of record and the names and addresses of the owners of the wells as shown in the Department’s well registry. The director shall not determine that the groundwater withdrawals will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells under subsection (B)(1) of this Section if within 60 days after the date on the notice, or a longer time period approved by the director, the applicant submits one of the following for each well of record identified in the notice:

1. A signed and notarized consent form from the owner of the well of record consenting to the withdrawals. The applicant shall use the consent form furnished by the director; or

2. Evidence satisfactory to the director that the address of the owner of the well of record as shown in the Department’s well registry records is inaccurate and that the applicant made a reasonable attempt to locate the current owner of the well of record but was unable to do so.

D. If the director determines that the groundwater withdrawals will have the effect described in subsection (B)(3) of this Section on one or more wells of record in existence as of the date of receipt of the application, the director shall notify the applicant in writing of the location of the wells of record and the names and addresses of the owners of the wells as shown in the Department’s well registry. The director shall not determine that the groundwater withdrawals will cause unreasonably increasing damage to surrounding land or other water users from the concentration of wells under subsection (B)(3) of this Section if within 60 days after the date on the notice, or a longer time period approved by the director, the applicant submits one of the following for each well of record identified in the notice:

1. A signed and notarized consent form from the owner of the well of record consenting to the withdrawals. The applicant shall use the consent form furnished by the director; or

2. Evidence satisfactory to the director that the address of the owner of the well of record as shown in the Department’s well registry records is inaccurate and that the applicant made a reasonable attempt to locate the current owner of the well of record but was unable to do so.

E. At any time before a final determination under this Section, the applicant may:

1. Amend the application to change the location of the proposed well or wells or the amount of groundwater to be withdrawn from the proposed well or wells to lessen the degree of impact on wells of record or regional land subsidence; or

2. Agree to construct or operate the proposed well or wells in a manner that lessens the degree of impact on wells of record or regional land subsidence. The director shall indicate in the permit that compliance with the agreement is a condition of the permit to use the well or wells to withdraw groundwater for transportation to an active management area under A.R.S. § 45-559.

R12-15-1308. Replacement Wells in Approximately the Same Location

A. For purposes of A.R.S. §§ 45-544, 45-596, and 45-597, a replacement well in approximately the same location is a proposed well to which all of the following apply:

1. The proposed well will be located no greater than 660 feet from the original well, and the location of the original well can be determined at the time the notice of intention to drill the proposed well is filed;

2. Except as provided in subsections (A)(3) and (A)(4) of this Section, the proposed well will not annually withdraw an amount of water in excess of the maximum annual capacity of the original well. The director shall determine the maximum annual capacity of the original well by multiplying the maximum pump capacity of the original well in gallons per minute by 525,600, and then converting the result into acre-feet by dividing the result by 325,851 gallons. The director shall presume that the maximum pump capacity of the original well is the maximum pump capacity of the well in gallons per minute as shown in the Department’s well registry records, except that:

a. If the director has reason to believe that the maximum pump capacity as shown in the Department’s well registry records is inaccurate, or if the applicant submits evidence demonstrating that the maximum pump capacity as shown in the Department’s well registry records is inaccurate, the director shall determine the maximum pump capacity by considering all available evidence, including the depth and diameter of the well and any evidence submitted by the applicant; or

b. If the Department’s well registry records do not show the maximum pump capacity of the original well, the director shall not approve the proposed well as a replacement well in approximately the same location unless the applicant demonstrates to the director’s satisfaction the maximum pump capacity of the original well;

3. If a well permit was issued for the original well under A.R.S. § 45-599, the proposed well will not annually withdraw an amount of groundwater in excess of the maximum annual volume set forth in the well permit;

4. If a recovery well permit was issued for the well to be replaced pursuant to A.R.S. § 45-834.01(B) and the permit sets forth a maximum annual volume of stored water that may be recovered from the well, the proposed well will not annually recover an amount of stored water in excess of the maximum annual volume set forth in the recovery well permit;

5. If the well to be replaced has been physically abandoned in accordance with R12-15-816, a notice of intention to drill the proposed well is filed no later than 90 days after the well to be replaced was physically abandoned; and

6. If the proposed well will be used to withdraw groundwater from the Little Colorado river plateau groundwater basin for transportation away from the basin pursuant to A.R.S. § 45-544(B)(1), one of the following applies:

a. The original well was drilled on or before January 1, 1991, or was drilled after that date pursuant to a notice of intention to drill that was on file with the Department on that date; or

b. The director previously determined that the withdrawal of groundwater from the original well for transportation away from the Little Colorado river plateau groundwater basin complies with R12-15-1304.

B. After a replacement well in approximately the same location is drilled, the replacement well may be operated in conjunction with the original well and any other wells that replaced the original well if the total annual withdrawals from all wells do not exceed the maximum amount allowed under subsection (A)(2), (A)(3), or (A)(4) of this Section, whichever applies.

C. A proposed well may be drilled as a replacement well in approximately the same location for more than one original well if the criteria in subsections (A)(1), (A)(5), and (A)(6) of this Section are met with respect to each original well and if the total annual withdrawals from the proposed well will not exceed the combined maximum annual amounts allowed for each original well under subsections (A)(2), (A)(3), or (A)(4) of this Section, whichever apply.

D. The director may include conditions in the approval of the notice of intention to drill the replacement well to ensure that the drilling and operation of the replacement well meets the requirements of this Section.
