      (13) Corrective action measures under this administrative regulation shall be initiated and completed within a period of time as specified by the cabinet considering the extent of contamination.

      (14) Corrective action measures under this administrative regulation may be terminated upon approval of the cabinet when the owner or operator demonstrates that concentrations have been reduced to levels below the maximum contaminant level or naturally occurring background.

 

      Section 9. Statistical Methods for Groundwater Analysis. (1) The owner or operator shall specify in the permit application one (1) of the following statistical methods to be used in evaluating groundwater monitoring data for each parameter in Section 11 of this administrative regulation. The statistical test chosen shall be conducted separately for each parameter in Section 11 of this administrative regulation in each well for each monitoring event, and the results shall be maintained as part of the facility record throughout the operating and postclosure life of the facility.

      (a) A parametric analysis of variance (ANOVA) followed by multiple comparisons 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.

      (b) An analysis of variance (ANOVA) based on ranks followed by multiple comparisons 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.

      (c) 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.

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

      (e) Another statistical method approved by the cabinet based on justification included in the permit application that the method meets the requirements of subsection (2) of this section.

      (2) Any statistical method chosen under subsection (1) of this section shall comply with the following performance standards, as appropriate:

      (a) The statistical method used to evaluate groundwater monitoring data shall be appropriate for the distribution of chemical parameters or hazardous constituents. If the distribution of the chemical parameters or hazardous constituents is shown by the owner or operator to be inappropriate for a normal theory test, then the data shall be transformed or a distribution-free theory test shall be used. If the distributions for the constituents differ, more than one (1) statistical method may be needed.

      (b) 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 of no less than 0.01 for each testing period. If a multiple comparisons 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 shall not apply to tolerance intervals, prediction intervals, or control charts.

      (c) 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 protective of human health and the environment. The parameters shall be determined after considering the number of samples in the background database, the data distribution, and the range of the concentration values for each constituent of concern.

      (d) 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 must contain, shall be protective of human health and the environment. These parameters shall be determined after considering the number of samples in the background database, the data distribution, and the range of the concentration values for each constituent of concern.

      (e) The statistical method shall account for data below the limit of detection with one (1) or more statistical procedures that are protective of human health and the environment. 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.

      (f) 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.

      (3) The owner or operator shall determine whether or not there is a statistically significant increase over background values for each parameter or constituent required in the particular groundwater monitoring program that applies to the solid waste site or facility.

      (a) In determining whether a statistically significant increase has occurred, the owner or operator shall compare the groundwater quality of each parameter or constituent at each monitoring well to the background value of that constituent, according to the statistical procedures and performance standards specified under subsections (1) and (2) of this section.

      (b) Within thirty (30) days after receiving sampling results, the owner or operator shall determine whether there has been a statistically significant increase over background at each monitoring well.
