Section R12-15-710 - Designation of Assured Water Supply

A. A municipal provider applying for a designation of assured water supply shall submit an application on a form prescribed by the Director with the fee required by R12-15-103(C) and provide the following:

1. The applicant's current demand;

2. The applicant's committed demand;

3. The applicant's projected demand for the proposed term of the designation;

4. If the applicant is seeking a reduction in the estimated water demand because gray water reuse systems will be installed, sufficient information for the Director to determine the appropriate reduction in demand;

5. The proposed term of the designation, which shall not be less than two years;

6. Evidence that the criteria in subsection (E) of this Section are met; and

7. Any other information that the Director determines is necessary to decide whether an assured water supply exists for the municipal provider.

B. An application for a designation shall be signed by:

1. If the applicant is a city or town, the city or town manager or a person employed in an equivalent position. The application shall also include a resolution of the governing body of the city or town, authorizing that person to sign the application; or

2. If the applicant is a private water company, the applicant's authorized officer, managing member, partner, trust officer, trustee, or other person who performs similar decision-making functions for the applicant.

C. The Director shall give public notice of an application for designation in the same manner as provided for certificates in A.R.S. § 45578. For an application to modify a designation of assured water supply to which Subsection (G) of this Section applies, the physical availability of the groundwater and stored water to be recovered outside the area of impact of storage sought to be included in the designation shall not be grounds for an objection.

D. After a complete application is submitted, the Director shall review the application and associated evidence to determine:

1. The annual volume of water physically, continuously, and legally available for at least 100 years

2. The term of the designation, which shall not be less than two years;

3. The applicant's estimated water demand. If the applicant demonstrates that gray water reuse systems will be installed, the Director shall reduce the estimated water demand for the subdivision by the volume the Director determines is likely to be saved through the gray water reuse systems;

4. The applicant's groundwater allowance; and

5. Whether the applicant has demonstrated compliance with all requirements in subsection (E) of this Section.

E. The Director shall designate the applicant as having an assured water supply if the applicant demonstrates all of the following:

1. Sufficient supplies of water are physically available to meet the applicant's estimated water demand, according to the criteria in R12-15-716, except as provided in subsection (G) of this Section;

2. Sufficient supplies of water are continuously available to meet the applicant's estimated water demand, according to the criteria in R12-15-717;

3. Sufficient supplies of water are legally available to meet the applicant's estimated water demand, according to the criteria in R12-15-718;

4. The proposed sources of water are of adequate quality, according to the criteria in R12-15-719;

5. The applicant has the financial capability to construct adequate delivery, storage, and treatment works in a timely manner according to the criteria in R12-15-720;

6. Any proposed groundwater use is consistent with the management plan in effect at the time of the application, according to the criteria in R12-15-721; and

7. Any proposed use of groundwater withdrawn within an AMA is consistent with the management goal, according to the criteria in R12-15-722.

F. The Director shall review an application for a designation of assured water supply pursuant to the licensing time-frame provisions in R12-15-401.

G. For an application seeking to modify a designation of assured water supply, the Director shall not review the physical availability of the volume of groundwater and stored water to be recovered outside the area of impact sought to be included in the designation if the total volume of those sources sought to be included in the designation does not exceed the total volume of those sources included in the previous designation of assured water supply that are required to be accounted for according to R12-15-716(B)(3)(c)(ii), minus the sum of the following:

1. The volume of groundwater withdrawn by the applicant since the previous designation of assured water supply order issuance date; and

2. The volume of stored water recovered outside the area of impact by the applicant since the previous designation of assured water supply order issuance date.
