NECESSITY, FUNCTION, AND CONFORMITY: KRS Chapter 224 requires the cabinet to promulgate administrative regulations for the treatment, management, processing or disposal of wastes. KRS 224.40-305 requires that persons engaging in the management, processing or disposal of waste obtain a permit. This chapter establishes the minimum technical standards for solid waste sites or facilities. This administrative regulation sets forth the standards for groundwater monitoring and corrective action.

Section 1. Applicability. The requirements of this administrative regulation apply to owners and operators of contained, construction/demolition, and residual landfills, Class II and Class III land-farming facilities, other solid waste sites or facilities at which the cabinet determines groundwater monitoring shall be required and solid waste sites or facilities required to accomplish corrective action as a result of documented groundwater contamination. Sections 1 through 7 of this administrative regulation do not apply to landfarming facilities permitted pursuant to 401 KAR 48:200. Land-farming facilities required to accomplish corrective action shall comply with Section 8 of this administrative regulation. The owner or operator shall satisfy the requirements of this administrative regulation for all wastes (or constituents thereof) contained in waste management units at the facility regardless of the time at which waste was placed in such unit. Designs, reports, and plans constituting the public practice of geology, as defined at KRS 322A.010, shall be developed by a person registered pursuant to KRS Chapter 322A, except as provided for by KRS 322A.080.

Section 2. Surface Water Monitoring Plan. A surface water monitoring plan as required in Section 5 of 401 KAR 47:190 shall include:

(1) Documentation that the applicant currently holds or has applied for a KPDES permit for all structures that shall be used to control storm water run-off and all point source discharges.

(2) The location of surface water monitoring points identified on the engineering plans. The surface water monitoring points shall be located such that the sampling shall characterize the quality of water unaffected by the landfills and shall be located such that the sampling shall determine if water leaving the landfill in surface drainage is contaminated with leachate. Sampling protocol shall measure surface water under base flow conditions that continues to drain after storm-induced surface run-off has ceased.

(3) A schedule and list of analytical parameters for the quarterly surface water sampling program. The parameters to be analyzed for the water samples shall include at a minimum: chlorides, sulfate, iron, sodium, total organic carbon or biochemical oxygen demand, chemical oxygen demand, specific conductance, total suspended solids, total dissolved solids, total solids and pH.

(4) A form to record the results of the surface water sample analyses.

(5) Prior to the disturbance of any areas proposed for development in a landfill permit application, the owner shall analyze samples of the surface water points and submit the results to the cabinet. The sampling shall include a minimum of two (2) samples collected at no less than thirty (30) day intervals and shall be sufficient to characterize the existing surface water quality.

Section 3. Groundwater Quality Characterization. A groundwater characterization as required in 401 KAR 47:180 shall contain the chemical characteristics of the upper most aquifer down to and including the lowest aquifer that may be affected by the site or facility. This description shall include results of analysis of at least two (2) samples of groundwater from the site before waste placement for the parameters listed in Section 10 of this administrative regulation. The number of samples collected for the groundwater quality characterization shall be consistent with the statistical method for groundwater analysis to be performed in Section 9 of this administrative regulation.

(1) For facilities permitted before May 8, 1990, the data required by this section shall be taken beginning with the first anniversary date of the issuance of the permit after May 8, 1990, and shall be for the parameters listed in Section 11 of this administrative regulation.

(2) Monitoring wells under this section shall be designed, constructed and maintained according to Section 6 of this administrative regulation. Sampling and analysis shall be conducted in accordance with a plan approved by the cabinet in accordance with the requirements of Section 7 of this administrative regulation.

Section 4. Groundwater Monitoring Plan. A groundwater monitoring plan as required in 401 KAR 47:190 or 401 KAR 48:200 shall include:

(1) The number, location and depth of proposed monitoring points;

(2) Preoperational data showing existing groundwater quality, as required in the groundwater quality characterization in Section 3 of this administrative regulation;

(3) A groundwater sampling and analysis plan. The procedures, methods and techniques shall be approved by the cabinet. The plan shall include:

(a) Procedures and techniques designed to accurately measure groundwater quality upgradient, and downgradient of the proposed waste disposal area;

(b) Cabinet approved sampling methods including procedures and techniques for sample collection, sample preservation and sample shipment;

(b) A description of a proposed groundwater monitoring system capable of completely and accurately monitoring groundwater contamination.

Section 5. Design Requirements for Groundwater Monitoring Systems. The groundwater quality monitoring system to be utilized in the groundwater monitoring plan shall accurately analyze groundwater quality and characterize local groundwater flow and flow systems. The system shall consist, at a minimum, of the following:

(1) At least one (1) reference or background well at a point hydraulically upgradient from the disposal area in the direction of increasing static head that is capable of providing data representative of groundwater not affected by the solid waste site or facility. When the solid waste site or facility occupies the most upgradient position in the flow system, sufficient downgradient or side gradient monitoring wells shall be placed to accurately characterize the groundwater quality and regional and local groundwater flow and flow systems. Reference wells shall be located so that they shall not be affected by groundwater contamination from the disposal area; and

(2) At least three (3) monitoring wells at points hydraulically connected in the direction of decreasing static head from the area in which solid waste has been or shall be disposed. In addition to three (3) downgradient wells, the cabinet may allow one (1) or more springs for monitoring points if the springs are hydraulically downgradient from the area in which solid waste has been or shall be disposed, if the springs are sampled in a manner approved by the cabinet, and if the springs otherwise meet the requirements of the cabinet. Downgradient monitoring wells shall be located so that they shall provide early detection of groundwater contamination and progressive monitoring of the phases and units of the site or facility.

Section 6. Requirements for Monitoring Well Construction.

(1) Precautions shall be taken during drilling and construction of monitoring wells to avoid introducing contaminants into a borehole. Only potable water shall be used in drilling monitoring wells unless otherwise approved by the cabinet. Drilling muds shall not be used except with prior approval of the cabinet. Air systems and drilling lubricants shall not introduce contaminants into the boreholes.

(2) Decontamination of all equipment to be placed into the boring shall be performed before use at the site and between boreholes. Where possible, upgradient wells shall be drilled first.

(1) Parameters Listing. Owners or operators of solid waste sites or facilities that require groundwater monitoring shall conduct sampling and analysis from each monitoring well for the parameters listed in Section 11 of this administrative regulation.

(2) Reporting of analysis results. Analyses of data required by this section shall be submitted to the cabinet on a form provided by the cabinet within sixty (60) days of sampling or fifteen (15) days after completing the statistical analysis required by Section 9 of this administrative regulation, whichever is sooner, unless the cabinet approves another time period in the permit. Frequency of sampling shall be as indicated in Section 11 of this administrative regulation.

(3) If analysis of the sample results indicates contamination as specified in Section 8(1) of this administrative regulation, the owner or operator shall notify the cabinet within forty-eight (48) hours of receiving the statistical analysis results required by Section 9 of this administrative regulation and shall arrange for the cabinet to split a sample no later than ten (10) days from the receipt of the results.

Section 8. Groundwater Contamination Assessment and Corrective Action.

(1) The operator of a solid waste site or facility shall be required to prepare and submit a groundwater assessment plan if laboratory analyses of one (1) or more monitoring wells at the site or facility shows the presence of one (1) or more parameters listed in 40 CFR 302.4, Appendix A as of October 1988, above the maximum containment level (MCL) as specified in 401 KAR 47:030 or significant increase over naturally occurring background levels for parameters that have no MCL. For parameters that have no maximum contaminant levels a significant increase over background shall be determined using a statistical test as specified in Section 9 of this administrative regulation.

(2) Confirmation sampling. The owner or operator of a solid waste site or facility shall not be required to submit an assessment plan if the following conditions are met:

(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 ground-water 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 ground-water 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.
