Section 811.93. Operating an ASR system.

 

(1)  Department approval to operate an ASR system shall be obtained prior to recovery of any water retrieved through an aquifer storage recovery well into a municipal water system.

(2)  Only the owner of a municipal water system may submit a request to operate an ASR system.

(3)  Completion of an ASR pilot study is required before a municipal water system may submit a request to operate an ASR system.

(4)  Completion of an ASR system development test and approval of the department is required before any additional aquifer storage recovery well that was not approved as part of an original request to operate an ASR system is connected to the existing ASR system.

(5)  A request to operate an ASR system shall be submitted to the department in writing and shall contain the following:

(a) A copy of the final report of the approved ASR system pilot study and copies of any approved ASR system development studies conducted by the municipal water system.

(b) A final plans and specifications report that describes the components of the ASR system. The final plans and specifications report shall include as built drawings for each aquifer storage recovery well and each monitoring well that was constructed as part of the ASR system pilot study or ASR system development study. The report shall also include descriptions of pumping equipment, piping and other appurtenances that are installed or required for ASR system operation.

(c) A proposed final operating plan that describes the entire ASR cycle and shows how the ASR system will be integrated into municipal water system operations. The proposed final operating plan shall contain details including the total volume of water to be injected, rate of injection, pressure of injection, length of the water storage period, rate of recovery, post-recovery water treatment techniques necessary to maintain a distribution system disinfectant residual, and methods for disposing of any water that cannot be recovered into the water distribution system.

(d) A proposed demand management and water accountability plan that describes actions which the municipal water system is currently conducting or will be initiating to ensure that groundwater and surface water resources are conserved and used as efficiently as possible.

(e) A proposed compliance and monitoring plan that lists all sampling parameters and provides details on monitoring schedules, monitoring locations, sampling methods and quality assurance techniques that will be followed to ensure that compliance with the requirements set forth in s. NR 811.88 is maintained. The compliance and monitoring plan shall provide for testing of the water that is to be injected, stored and recovered through each aquifer storage recovery well and for the groundwater present in any monitoring well that is installed as part of the ASR system. Parameters to be analyzed for each water quality sample collected, the locations for sample collection and the frequency at which water quality samples are to be collected shall be determined by the department following a review of the final ASR system pilot study report or ASR system development study report, the proposed operating plan, the proposed monitoring plan and the drinking water quality monitoring schedule currently followed by the municipal water system. Unless otherwise specified by the department, all water quality results obtained from ASR system compliance monitoring activities shall be compiled and submitted to the department on an annual basis and at least 45 days prior to the start of each new ASR cycle.

(6)  The department may require modification of any plans and specifications, operating plans, demand management and water accountability plans or compliance and monitoring plans required in sub. (5) in any manner necessary to ensure compliance with the performance standards set forth in s. NR 811.88 .

(7)  If requested, the department may consider and approve the modification of plans and specifications, operating plans, demand management and water accountability plans or compliance and monitoring plans required in sub. (5) if information submitted in support of a requested modification demonstrates to the satisfaction of the department that the proposed modifications will continue to ensure compliance with the standards set forth in s. NR 811.88 and any other applicable requirements contained in ch. NR 811 .
