King Coal Mine (C-1981-035) TR -20 Adequacy Review #3 Response <br />GCCE Dec. 2015: King I: Due to the need to set a drill rig on a relatively flat surface, <br />drill hole locations are placed at intervals along the existing road that accesses the top <br />of the existing refuse pile. These holes are placed such that they will intersect refuse <br />generated only from the King I mine over various periods of time. Holes drilled from <br />higher locations would intersect refuse generated from the King II mine, which is to be <br />sampled 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 8s IA, <br />in order to collect representative samples of King I refuse, without intercepting pre - <br />refuse pile base material which could contaminate the samples. <br />King II: Sample locations were chosen to be spaced at approximate intervals of one <br />hole per square mile as per recommendations from CDRMS guidance document <br />"Guidelines for the Collection of Baseline Water Quality and Overburden Geochemistry <br />Data". Holes labelled RCF # 1 thru #3 were chosen to take advantage of locations <br />which are legally and physically accessible within the King II mine. RCF #4 is an <br />available drill core which was collected in 2015 as approved by TR -22. <br />These items are addressed in more detail in the comprehensive plan which has been <br />attached to be included as King II Appendix 4(8). <br />4. Please also indicate: <br />i. Who will be collecting these samples? <br />ii. Who will be analyzing these samples? <br />GCCE Dec. 2015: These items are addressed in the comprehensive plan which has been <br />attached to be included as King II Appendix 4(8). <br />Please find attached: <br />• King I Table of Contents pages ii 8s iii <br />• King I Permit Cover Page <br />• King I Section 2.04.6, page 4 <br />• King I Section 2.05.3 pages 2, 3, 4 & 5 <br />• King I Section 2.05.4 pages 4, 5 & 5a <br />• Maps King I-016 & 016A <br />• King II Permit Cover Page <br />• King II Section 2.04.6, page 7 <br />• King II Table of Contents pages ii & iii <br />• King II Appendix 4(8) <br />• King I Refuse Pile Compaction Tests 4/2/15 & 8/6/15 <br />• TR -20 Replacement Page Schedule <br />Please contact Tom Bird at 970.385.4528 x 6503 with questions or comments. <br />Sincerely, <br />Tom Bird <br />0____ _Z_ D <br />Manager of Coal Services <br />GCC Energy, LLC <br />
