REFUSE PILE CHEMISTRY <br />A discussion of the chemistry and comprehensive sampling plan of the coal mine <br />waste material generated from the King I and King II mines has been added to the <br />permit with Minor Revision MR -41, and can be found as King II Appendix 4(8). Upon <br />approval of MR -41, sampling will commence as soon as possible, weather permitting. <br />Analysis results will be compiled into a report which will be forwarded to the Division <br />and inserted into King II Appendix 4(8). <br />At the King I Mine: Samples will be collected from three drill holes located as shown <br />on Appendix 4(8) Map 1 and Map 1A, Detail. Map 1 represents a survey performed in <br />January, 2006 at a time when the refuse pile consisted only of King I refuse material. <br />The cross-sections on the left portion of the map show the holes to be drilled and the <br />existing surface and refuse pile/pre-refuse pile interface. <br />Due to the need to set a drill rig on a relatively flat surface, drill hole locations are <br />placed at intervals along the existing road that accesses the top of the existing refuse <br />pile. These holes are placed such that they will intersect refuse generated only from <br />the King I mine over various periods of time. Holes drilled from higher locations <br />would intersect refuse generated from the King II mine, which is to be sampled <br />separately from the King I refuse. These holes will be drilled to depths of <br />approximately 20' to 35 feet, depending on the cross-section as shown on Maps 1 & <br />IA, in order to collect representative samples of King I refuse, without intercepting <br />pre -refuse pile base material which could contaminate the samples. <br />At the King II imine: As shown on Appendix 4(8) Map 2, four additional samples will <br />be collected from existing drill cores or from within the current workings of the King <br />II mine. King II sample locations are spaced at approximately one hole per square <br />mile as per CDRMS guidance document "Guidelines for the Collection of Baseline <br />Water Quality and Overburden Geochemistry Data". <br />Holes labelled RCF # 1 thru #3 were chosen to take advantage of locations which are <br />legally and physically accessible within the King II mine. RCF #4 is an available drill <br />core which was collected in 2015 as approved by TR -22. <br />CC Energy, LLC <br />Section 2.04.6 <br />Page 8 <br />King II Mine <br />September 14, 2016 (MR -41) <br />
