(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.
