(A)
Ground water monitoring well system. The owner or operator of any facility
disposing of debris on or after September 30, 1996, shall have a ground water
monitoring well system unless the limits of debris placement meet the criteria
in paragraph (B) of rule
3745-400-09
of the Administrative Code. Ground water monitoring shall be implemented
no
not later
than required by paragraph (R) of rule
3745-400-11
of the Administrative Code. The number, spacing, and depth of ground water
monitoring wells included in the monitoring well system shall be capable of
determining the quality of the ground water under the facility and be based on
site-specific hydrogeologic information contained in the site characterization
report required in paragraph (C) of rule
3745-400-09
of the Administrative Code. The monitoring well system is not required to be
capable of determining the impact of the facility on the quality of the ground
water beneath the facility.
The owner or operator shall describe the ground water
monitoring well system in a plan as part of the facility design plan required
by rule
3745-400-07
of the Administrative Code. The ground water monitoring well system plan shall
be certified by a qualified ground water scientist that the system meets the
requirements of paragraph (A) of this rule. If the ground water monitoring well
system is constructed in phases, each phase shall be described by a qualified
ground water scientist in the license application submitted prior to the
placement of debris in the fill area relevant to that phase. The configuration
of the ground water monitoring well system at all stages of the facility
development shall be described using maps and a narrative.
(1) The ground water monitoring well system
shall include a sufficient number of background and downgradient monitoring
wells, installed at appropriate locations and depths, to yield ground water
samples from the first continuous significant zone of saturation underlying the
facility.
(2) All monitoring wells
shall be designed, installed, and developed in a manner that allows the
collection of ground water samples that are representative of ground water
quality in the geologic unit being monitored. The ground water monitoring well
system plan shall contain a drawing with specifications of the typical
construction of any wells not yet constructed. At a minimum
, the ground water monitoring well system plan shall
include the following:
(a) Monitoring wells
shall be cased in a manner that maintains the integrity of the monitoring well
boreholes.
(b) The annular space,
i.e., the space between the borehole and the well casing, above the sampling
depth shall be sealed to prevent the contamination of the samples and the
ground water.
(c) The casing shall
be screened or perforated and surrounded by sand or gravel in such a way that
allows for the minimization of the passage of formation materials into the
well.
(3) Upon the
installation of ground water monitoring wells, a construction certification
report shall be submitted in accordance with rule
3745-400-08
of the Administrative Code.
(B)
Reporting
Sampling and
reporting. Annually,
at least by
not later than September thirtieth of each year,
the owner or operator of a licensed facility shall determine the quality of
ground water from wells that are part of the ground water monitoring well
system required in paragraph (A) of this rule
and
certain constituents in the leachate from the leachate collection system
required in paragraph (F) of rule
3745-400-07
of the Administrative Code. The leachate quality data shall be used to
supplement ground water monitoring data to determine if the leachate could be
causing any changes in the quality of the ground water. These determinations
shall be submitted at least annually to the licensing authority in a report
signed by a qualified ground water scientist. The ground water monitoring
determinations and report do not have to determine the impact of the facility
on the quality of the ground water beneath the facility. The report shall
provide the following:
(1) The ground water
quality data required by paragraph (C) of this rule displayed using tables,
tri-linear diagrams, stiff diagrams, time vs. concentration plots or any other
format deemed appropriate by the qualified ground water scientist. The report
shall describe any significant ground water quality changes over time and
differences between up-gradient and down-gradient wells
(2) A narrative of the sampling and analysis
procedures used. After the initial report submittal, only amendments to the
already submitted sampling and analysis procedures need to be submitted with
each subsequent report. The sampling and analysis procedures shall be
protective of human health and the environment and shall be designed to ensure
monitoring results that provide an accurate representation of ground water
quality. The narrative of the sampling and analysis procedures shall include a
detailed description of the equipment, procedures, and techniques used for the
following:
(a) Measurement of ground water
elevations.
(b) Collection of
ground water samples, including the following:
(i) Well evacuation.

monitoring well system at the facility continues to meet the requirements of
rule
3745-400-09
of the Administrative Code.

abandonment of any monitoring wells, piezometers, and other measurement,
sampling, and analytical devices that have been installed or abandoned since
the last report.
(6) Documentation
of the qualifications of the certifying qualified ground water
scientist.
