Ariz. Rev. Stat. § 49-243
A. The director shall consider, and the applicant for an individual permit may be required to furnish with the application, the following information:
B. The director shall issue a permit to a person for a facility other than water storage at a storage facility pursuant to title 45, chapter 3.1 if the person demonstrates that either paragraphs 1 and 2 or paragraphs 1 and 3 of this subsection will be met:
1. That the facility will be so designed, constructed and operated as to ensure the greatest degree of discharge reduction achievable through application of the best available demonstrated control technology, processes, operating methods or other alternatives, including, where practicable, a technology permitting no discharge of pollutants. In determining best available demonstrated control technology, processes, operating methods or other alternatives, the director shall take into account any treatment process contributing to the discharge, site specific hydrologic and geologic characteristics and other environmental factors, the opportunity for water conservation or augmentation and economic impacts of the use of alternative technologies, processes or operating methods on an industry-wide basis. A discharge reduction to an aquifer achievable solely by means of site specific characteristics does not, in itself, constitute compliance with this paragraph. The requirements of this paragraph for wetlands designed and constructed to treat municipal and domestic wastewater for underground storage pursuant to section 49-241, subsection B may be met by including seepage through the bottom of the facility if it is demonstrated that site characteristics can act to achieve performance levels established as the best available demonstrated control technology by the director. In addition, the director shall consider the following factors for existing facilities:
G. A discharging facility at an open pit mining operation shall be deemed to satisfy the requirements of subsection B, paragraph 1 of this section if the director determines that both of the following conditions are satisfied:
I. With respect to the following pollutants, the permit applicant for a new facility must meet the criteria of subsection B, paragraph 1 of this section to limit discharges to the maximum extent practicable regardless of cost:
K. The director shall consider and may prescribe in the permit the following terms and conditions as necessary to ensure compliance with this article:
L. With the consent of the applicant or permittee, the director may include in an aquifer protection permit for an existing facility the requirement that the applicant or permittee undertake a remedial action, as defined in section 49-281, to prevent, minimize or mitigate damage to the public health or welfare or to the waters of the state resulting from a discharge that occurred before August 13, 1986, if the following conditions are met:
N. The director may deny a permit for a facility if the director determines that the applicant is incapable of fully carrying out the terms and conditions of the permit, including any conditions that require monitoring or installing and maintaining discharge control measures. The following apply to an application for a permit or to an issued permit:
2. For the purposes of evaluating an applicant's financial competence for closure, the director may consider a closure strategy and cost estimate rather than a detailed closure plan. Except for a state or federal agency or a county, city, town or other local governmental entity, the cost estimate shall be based on the cost for the applicant or permittee to hire a third party to conduct the closure strategy or plan unless the financial responsibility mechanism provided pursuant to this subsection is a self-assurance or a guarantee and the director determines that the applicant or permittee is technically and financially capable of closing the facility at its own cost and, if necessary, of conducting postclosure monitoring and maintenance. Except for a state or federal agency or a county, city, town or other local governmental entity, the permittee shall update its cost estimate:
P. The director may issue a single area-wide permit applicable to facilities under common ownership and located in a contiguous geographic area in lieu of an individual permit for each facility. In issuing an area-wide permit, the demonstration required under subsection B, paragraphs 2 and 3 of this section may be considered collectively for all facilities included in the permit. The director may evaluate discharge reduction collectively for existing facilities in the pollutant management area by considering any one or all of the factors set forth in subsection B, paragraph 1 of this section. The director may consolidate those permit conditions listed in subsection K of this section that have general applicability to the facilities included in the area-wide permit. An area-wide permit shall specify all of the following:
