Current through Register Vol. 30, No. 50, December 13, 2024

Section R18-9-E701 - Recycled Water Individual Permit for an Advanced Reclaimed Water Treatment Facility

A. An application for a Recycled Water Individual Permit for an Advanced Reclaimed Water Treatment Facility must be submitted to the Department according to the requirements in R18-9-A703, as applicable.

B. Safe Drinking Water Act. For purposes of Safe Drinking Water Act requirements, water produced by an Advanced Reclaimed Water Treatment Facility shall be considered surface water for purposes of compliance with Title 18, Chapter 4 of the Arizona Administrative Code. Nothing in this section exempts an applicable facility from Safe Drinking Water Act requirements.

C. Design Report. In addition to the information required by subsection (A), the applicant shall submit a design report for the Advanced Reclaimed Water Treatment Facility according to a form prescribed by the Department and certified by an Arizona-registered professional engineer. The design report must include the following information:

1. Characterization of source water quantity and quality, including:

a. Average and anticipated minimum and maximum source water flows to the facility;

b. Concentrations of the source water's physical, microbiological, and chemical constituents regulated for drinking water Maximum Contaminant Levels under the Safe Drinking Water Act and which the Department determines are appropriate for the particular facility and source water;

c. Description and concentrations of constituents in the source water used for unit treatment process monitoring and assessment of unit treatment process efficacy, and

d. A list of unregulated microbial and chemical constituents and corresponding concentrations in the source water a facility proposes to monitor in order to assess the treatment effectiveness of the overall treatment train. The particular constituents will depend on consideration of factors, such as:

i. Occurrence of the constituent in source and local waters,

ii. Availability of standardized laboratory methods for quantification of the constituent,

iii. Usefulness as representatives of or surrogates for larger classes of constituents, and

iv. Availability of toxicity data for the constituent.

2. Description of, and results from, the pilot water treatment system for the facility or of analogous systems where comparable treatment components are demonstrated as appropriate for treating the particular characteristics of the applicant's proposed source water;

3. Identification and description of the technologies, processes, methodologies, and process control monitoring to be employed for microbial control;

4. Logarithmic reduction targets for microbial control, to ensure the product water is free of pathogens and suitable for potable use;

5. Identification and description of technologies, processes, methodologies and process control monitoring for chemical control;

6. Plan for monitoring the product water for public health protection;

7. Commissioning and startup plan, including preoperational and startup testing and monitoring, expected time-frame for meeting full operational performance, and any other special startup condition meriting consideration in the individual permit;

8. Operation and maintenance plan including corrective actions for out-of-range monitoring results and contingencies for non-compliant water;

9. Operator training plan; and

10. Documentation of technical, financial, and management capability.
