  (i) Hydrogeologic conditions do not allow the owner or operator of the CCR unit to determine what wells are hydraulically upgradient; or

  (ii) Sampling at other wells will provide an indication of background groundwater quality that is as representative or more representative than that provided by the upgradient wells; and

  (2) Accurately represent the quality of groundwater passing the waste boundary of the CCR unit. The downgradient monitoring system shall be installed at the waste boundary that ensures detection of groundwater contamination in the uppermost aquifer. All potential contaminant pathways shall be monitored.

  (b) The number, spacing, and depths of monitoring systems shall be determined based upon site-specific technical information that shall include thorough characterization of:

  (1) The multiunit groundwater monitoring system shall be equally as capable of detecting monitored constituents at the waste boundary of the CCR unit as the individual groundwater monitoring system specified in Subsections R315-319-91(a) through (c) for each CCR unit based on the following factors:

  (i) Number, spacing, and orientation of each CCR unit;

  (ii) Hydrogeologic setting;

  (iii) Site history; and

  (iv) Engineering design of the CCR unit.

  (2) If the owner or operator elects to install a multiunit groundwater monitoring system, and if the multiunit system includes at least one existing unlined CCR surface impoundment as determined by Subsection R315-319-71(a), and if at any time after October 19, 2015 the owner or operator determines in any sampling event that the concentrations of one or more constituents listed in appendix IV to Rule R315-319 are detected at statistically significant levels above the groundwater protection standard established under Subsection R315-319-95(h) for the multiunit system, then all unlined CCR surface impoundments comprising the multiunit groundwater monitoring system are subject to the closure requirements under Subsection R315-319-101(a) to retrofit or close.

  (e) Monitoring wells shall be cased in a manner that maintains the integrity of the monitoring well borehole.

  (c) Groundwater elevations shall be measured in each well immediately prior to purging, each time groundwater is sampled. The owner or operator of the CCR unit shall determine the rate and direction of groundwater flow each time groundwater is sampled. Groundwater elevations in wells which monitor the same CCR management area shall be measured within a period of time short enough to avoid temporal variations in groundwater flow which could preclude accurate determination of groundwater flow rate and direction.

  (d) The owner or operator of the CCR unit shall establish background groundwater quality in a hydraulically upgradient or background well(s) for each of the constituents required in the particular groundwater monitoring program that applies to the CCR unit as determined under Subsection R315-319-94(a) or Subsection R315-319-95(a). Background groundwater quality may be established at wells that are not located hydraulically upgradient from the CCR unit if it meets the requirements of Subsection R315-319-91(a)(1).

  (e) The number of samples collected when conducting detection monitoring and assessment monitoring, for both downgradient and background wells, shall be consistent with the statistical procedures chosen under Subsection R315-319-93(f) and the performance standards under Subsection R315-319-93(g). The sampling procedures shall be those specified under Subsections R315-319-94(b) through (d) for detection monitoring, Subsection R315-319-95(b) through (d) for assessment monitoring, and Subsection R315-319-96(b) for corrective action.

  (f) The owner or operator of the CCR unit shall select one of the statistical methods specified in Subsections R315-319-93(f)(1) through (5) to be used in evaluating groundwater monitoring data for each specified constituent. The statistical test chosen shall be conducted separately for each constituent in each monitoring well.

  (1) A parametric analysis of variance followed by multiple comparison procedures to identify statistically significant evidence of contamination. The method shall include estimation and testing of the contrasts between each compliance well's mean and the background mean levels for each constituent.

  (2) An analysis of variance based on ranks followed by multiple comparison procedures to identify statistically significant evidence of contamination. The method shall include estimation and testing of the contrasts between each compliance well's median and the background median levels for each constituent.

  (3) A tolerance or prediction interval procedure, in which an interval for each constituent is established from the distribution of the background data and the level of each constituent in each compliance well is compared to the upper tolerance or prediction limit.

  (4) A control chart approach that gives control limits for each constituent.

  (5) Another statistical test method that meets the performance standards of Subsection R315-319-93(g) and has been approved by the Director.

  (6) The owner or operator of the CCR unit shall obtain a certification from a qualified professional engineer stating that the selected statistical method is appropriate for evaluating the groundwater monitoring data for the CCR management area. The certification shall include a narrative description of the statistical method selected to evaluate the groundwater monitoring data.

  (g) Any statistical method chosen under Subsection R315-319-93(f) shall comply with the following performance standards, as appropriate, based on the statistical test method used:

  (1) The statistical method used to evaluate groundwater monitoring data shall be appropriate for the distribution of constituents. Normal distributions of data values shall use parametric methods. Non-normal distributions shall use non-parametric methods. If the distribution of the constituents is shown by the owner or operator of the CCR unit to be inappropriate for a normal theory test, then the data shall be transformed or a distribution-free, non-parametric, theory test shall be used. If the distributions for the constituents differ, more than one statistical method may be needed.

  (2) If an individual well comparison procedure is used to compare an individual compliance well constituent concentration with background constituent concentrations or a groundwater protection standard, the test shall be done at a Type I error level no less than 0.01 for each testing period. If a multiple comparison procedure is used, the Type I experiment wise error rate for each testing period shall be no less than 0.05; however, the Type I error of no less than 0.01 for individual well comparisons shall be maintained. This performance standard does not apply to tolerance intervals, prediction intervals, or control charts.

  (3) If a control chart approach is used to evaluate groundwater monitoring data, the specific type of control chart and its associated parameter values shall be such that this approach is at least as effective as any other approach in Section R315-319-93 for evaluating groundwater data. The parameter values shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

  (4) If a tolerance interval or a predictional interval is used to evaluate groundwater monitoring data, the levels of confidence and, for tolerance intervals, the percentage of the population that the interval shall contain, shall be such that this approach is at least as effective as any other approach in Section R315-319-93 for evaluating groundwater data. These parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

  (5) The statistical method shall account for data below the limit of detection with one or more statistical procedures that shall at least as effective as any other approach in Section R315-319-93 for evaluating groundwater data. Any practical quantitation limit that is used in the statistical method shall be the lowest concentration level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions that are available to the facility.

  (6) If necessary, the statistical method shall include procedures to control or correct for seasonal and spatial variability as well as temporal correlation in the data.

  (h) The owner or operator of the CCR unit shall determine whether or not there is a statistically significant increase over background values for each constituent required in the particular groundwater monitoring program that applies to the CCR unit, as determined under Subsection R315-319-94(a) or Subsection R315-319-95(a).

  (1) In determining whether a statistically significant increase has occurred, the owner or operator shall compare the groundwater quality of each constituent at each monitoring well designated pursuant to Subsection R315-319-91(a)(2) or (d)(1) to the background value of that constituent, according to the statistical procedures and performance standards specified under Subsections R315-319-93(f) and (g).

  (2) Within 90 days after completing sampling and analysis, the owner or operator shall determine whether there has been a statistically significant increase over background for any constituent at each monitoring well.

  (i) The owner or operator shall measure "total recoverable metals" concentrations in measuring groundwater quality. Measurement of total recoverable metals captures both the particulate fraction and dissolved fraction of metals in natural waters. Groundwater samples shall not be field-filtered prior to analysis.

  (j) The owner or operator of the CCR unit shall comply with the recordkeeping requirements specified in Subsection R315-319-105(h), the notification requirements specified in Subsection R315-319-106(h), and the Internet requirements specified in Subsection R315-319-107(h).

The owner or operator of a CCR surface impoundment or any lateral expansion of a CCR surface impoundment shall meet the requirements of Subsections R315-319-102(d)(2)(i) and (ii) prior to installing the final cover system required under Subsection R315-319-102(d)(3).

  (i) Free liquids shall be eliminated by removing liquid wastes or solidifying the remaining wastes and waste residues.

  (ii) Remaining wastes shall be stabilized sufficient to support the final cover system.

  (3) Final cover system. If a CCR unit is closed by leaving CCR in place, the owner or operator shall install a final cover system that is designed to minimize infiltration and erosion, and at a minimum, meets the requirements of Subsection R315-319-102(d)(3)(i), or the requirements of the alternative final cover system specified in Subsection R315-319-102(d)(3)(ii).

  (i) The final cover system shall be designed and constructed to meet the criteria in Subsections R315-319-102(d)(3)(i)(A) through (D). The design of the final cover system shall be included in the written closure plan required by Subsection R315-319-102(b).

  (A) The permeability of the final cover system shall be less than or equal to the permeability of any bottom liner system or natural subsoils present, or a permeability no greater than 1 x 10-5 cm/sec, whichever is less.

  (B) The infiltration of liquids through the closed CCR unit shall be minimized by the use of an infiltration layer that contains a minimum of 18 inches of earthen material.

  (C) The erosion of the final cover system shall be minimized by the use of an erosion layer that contains a minimum of six inches of earthen material that is capable of sustaining native plant growth.

  (D) The disruption of the integrity of the final cover system shall be minimized through a design that accommodates settling and subsidence.

  (ii) The owner or operator may select an alternative final cover system design, provided the alternative final cover system is designed and constructed to meet the criteria in Subsections R315-319-102(f)(3)(ii)(A) through (D). The design of the final cover system shall be included in the written closure plan required by Subsection R315-319-102(b).

  (A) The design of the final cover system shall include an infiltration layer that achieves an equivalent reduction in infiltration as the infiltration layer specified in Subsections R315-319-102(d)(3)(i)(A) and (B).

  (B) The design of the final cover system shall include an erosion layer that provides equivalent protection from wind or water erosion as the erosion layer specified in Subsection R315-319-102(d)(3)(i)(C).

  (C) The disruption of the integrity of the final cover system shall be minimized through a design that accommodates settling and subsidence.

  (iii) The owner or operator of the CCR unit shall obtain a written certification from a qualified professional engineer that the design of the final cover system meets the requirements of Section R315-319-102.

  (e) Initiation of closure activities. Except as provided for in Subsection R315-319-102(e)(4) and Section R315-319-103, the owner or operator of a CCR unit shall commence closure of the CCR unit no later than the applicable timeframes specified in either Subsection R315-319-102(e)(1) or (2).

  (1) The owner or operator shall commence closure of the CCR unit no later than 30 days after the date on which the CCR unit either:

  (i) Receives the known final receipt of waste, either CCR or any non-CCR waste stream; or

  (ii) Removes the known final volume of CCR from the CCR unit for the purpose of beneficial use of CCR.

  (2)(i) Except as provided by Subsection R315-319-102(e)(2)(ii), the owner or operator shall commence closure of a CCR unit that has not received CCR or any non-CCR waste stream or is no longer removing CCR for the purpose of beneficial use within two years of the last receipt of waste or within two years of the last removal of CCR material for the purpose of beneficial use.

  (ii) Notwithstanding Subsection R315-319-102(e)(2)(i), the owner or operator of the CCR unit may secure an additional two years to initiate closure of the idle unit provided the owner or operator provides written documentation that the CCR unit will continue to accept wastes or will start removing CCR for the purpose of beneficial use. The documentation shall be supported by, at a minimum, the information specified in Subsections R315-319-102(e)(2)(ii)(A) and (B). The owner or operator may obtain two-year extensions provided the owner or operator continues to be able to demonstrate that there is reasonable likelihood that the CCR unit will accept wastes in the foreseeable future or will remove CCR from the unit for the purpose of beneficial use. The owner or operator shall place each completed demonstration, if more than one time extension is sought, in the facility's operating record as required by Subsection R315-319-105(i)(5) prior to the end of any two-year period.

  (A) Information documenting that the CCR unit has remaining storage or disposal capacity or that the CCR unit can have CCR removed for the purpose of beneficial use; and

  (B) Information demonstrating that that there is a reasonable likelihood that the CCR unit will resume receiving CCR or non-CCR waste streams in the foreseeable future or that CCR can be removed for the purpose of beneficial use. The narrative shall include a best estimate as to when the CCR unit will resume receiving CCR or non-CCR waste streams. The situations listed in Subsections R315-319-102(e)(2)(ii)(B)(1) through (4) are examples of situations that would support a determination that the CCR unit will resume receiving CCR or non-CCR waste streams in the foreseeable future.

  (1) Normal plant operations include periods during which the CCR unit does not receive CCR or non-CCR waste streams, such as the alternating use of two or more CCR units whereby at any point in time one CCR unit is receiving CCR while CCR is being removed from a second CCR unit after its dewatering.

  (2) The CCR unit is dedicated to a coal-fired boiler unit that is temporarily idled, e.g., CCR is not being generated, and there is a reasonable likelihood that the coal-fired boiler will resume operations in the future.

  (3) The CCR unit is dedicated to an operating coal-fired boiler, i.e., CCR is being generated; however, no CCR are being placed in the CCR unit because the CCR are being entirely diverted to beneficial uses, but there is a reasonable likelihood that the CCR unit will again be used in the foreseeable future.

  (4) The CCR unit currently receives only non-CCR waste streams and those non-CCR waste streams are not generated for an extended period of time, but there is a reasonable likelihood that the CCR unit will again receive non-CCR waste streams in the future.

  (iii) In order to obtain additional time extension(s) to initiate closure of a CCR unit beyond the two years provided by Subsection R315-319-102(e)(2)(i), the owner or operator of the CCR unit shall include with the demonstration required by Subsection R315-319-102(e)(2)(ii) the following statement signed by the owner or operator or an authorized representative:

  I certify under penalty of law that I have personally examined and am familiar with the information submitted in this demonstration and all attached documents, and that, based on my inquiry of those individuals immediately responsible for obtaining the information, I believe that the submitted information is true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment.

  (3) For purposes of Sections R315-319-50 through 107, closure of the CCR unit has commenced if the owner or operator has ceased placing waste and completes any of the following actions or activities:

  (i) Taken any steps necessary to implement the written closure plan required by Subsection R315-319-102(b);

  (ii) Submitted a completed application for any required state or agency permit or permit modification; or

  (iii) Taken any steps necessary to comply with any state or other agency standards that are a prerequisite, or are otherwise applicable, to initiating or completing the closure of a CCR unit.

  (4) The timeframes specified in Subsections R315-319-102(e)(1) and (2) do not apply to any of the following owners or operators:
