Resolved Items <br />1. The plan provides very few specifics or justifications relevant to the King II mine. <br />Please provide a site specific plan. <br />GCCE Dec. 2015: A comprehensive plan addressing the chemistry of coal mine waste generated <br />from the King I and King II mines, and stored in the Refuse Pile located at the King I mine, has <br />been attached to be included as King II Appendix 4(8). Pages King I 2.04.6 page 4 and King II <br />2.04.6 page 7 have been modified to direct the reader to the material in Appendix 4(8). <br />2. Copper and Cadmium, listed in Table 3 of the DBMS guidance document are not listed in the <br />proposed chemical parameters and Methods of Analysis table provided by GCC. The Table <br />provided by GCC is a copy of Table 5 in the DRMS guidance document, which is "Overburden <br />Geochemistry — Suggested Methods of Analysis". Table 3 of the guidance document lists the <br />Suggested Chemical Parameters. No rational for leaving Cadmium and Copper off the list of <br />proposed analytes to be monitored was provided. <br />Please either provide a rationale for not monitoring these analytes or include them on the parameters to <br />be monitored. <br />GCCE Dec. 2015: Cadmium and Copper have been added to the list of proposed analytes to be <br />monitored. <br />Resolved as per Cadmium and Copper. <br />The following items remain unresolved pending receipt of final leachate analysis and monitoring <br />plan form GCC Energy. <br />DRMS April. 2016 (new): Additional analytes may be recommended by DRMS as other research and <br />data are analyzed. <br />3. No discussion or rational was provided as to the selected number or location of samples. <br />Please discuss: <br />i. how many samples will be taken <br />GCCE Dec. 2015: King I: Samples will be collected from three drill holes located as shown on <br />Appendix 4(8) Map 1 and Map 1A, Detail. Map 1 represents a survey performed in January, <br />2006 at a time when the refuse pile consisted only of King I refuse material. The cross-sections on <br />the left portion show the holes to be drilled and the existing surface and refuse pile/pre-refuse pile <br />interface. <br />King II: As shown on Appendix 4(8) Map 2, four additional samples will be collected from existing <br />drill cores or from within the current workings of the King II mine. <br />ii. samplingfrequency <br />GCCE Dec. 2015: King I drill hole locations are spaced at approximately one-third intervals across <br />the refuse pile. <br />King II sample locations are spaced at approximately one hole per square mile as per CDRMS <br />guidance document "Guidelines for the Collection of Baseline Water Quality and Overburden <br />Geochemistry Data". <br />Prepared by: R.
