King Coal Mine (C-1981-035) TR -26 Adequacy Review #1 Response <br />Text from your November 25, 2015 document is reprinted below. Responses by GCC <br />Energy are shown in underlined italics. <br />A. Rule 2.04.7 (1)(a)(i) Hydrolo2y Description: Groundwater Information <br />The monitoring wells proposed in this technical revision (TR 26) are put forward in order to provide results <br />describing the ground water hydrology, and include determining the depth below the surface that groundwater <br />exists and the horizontal extent of the potentiometric surface of any aquifer that may exist between the Menefee <br />"A" coal seam and the deeper Menefee `B" coal seam. These monitoring wells are also meant to provide data <br />answering the question of whether or not the Cliffhouse Sandstone produces water. <br />DRMS has concerns regarding the King II Mine Cliffhouse monitoring well design as shown in <br />Appendix 4(5). The four (4) borings are not designed as monitoring wells, and are proposed to be left as open <br />holes with a three foot bentonite seal placed in the bottom of each hole. <br />1. DRMS Nov 2015: Review of the "A" Coal Seam and Menefee interburden monitoring well designs <br />are adequate. <br />GCCE Mar 2016: Noted <br />2. DRMS Nov 2015: Please revise the monitoring well design specifications in Appendix 4(5) to include <br />well construction designs as opposed to open boreholes for at least two of the four Cliffhouse <br />monitoring well locations. These shall be located with one up gradient and one downgradient of the <br />mining area. The revised designs should include an updated well completion diagram and revised <br />specifications table. <br />GCCE Mar 2016: Discussions are still on-going with the Division and GCC EneW concerning the <br />monitoring well design specifications in Appendix 4(5). We believe that a design other than those submitted <br />will diminish the effectiveness of the wells and make it impossible to determine where any above -seam water <br />horizons might be. Any required modif cation to the well designs will be forwarded to the Division upon <br />final determination. <br />B. Rule 2.04.9 Soil Resource Information <br />For areas slated for disturbance, this rule requires submission of adequate soils information that includes <br />information describing the soil horizons that include soil sampling and analysis results to determine the horizons <br />suitability for salvage. Also required are a soils map portraying sampling locations and proposed salvage <br />horizons. It is difficult to ascertain which soil series Cluster MW -2 falls in given the quality of the Coal Lease <br />Map submitted with TR26. <br />3. DRMS Nov 2015: The soils resources information contained in the King II Mine permit section 2.04.9 <br />does not cover all the disturbed areas for the proposed monitoring well Clusters MW -1, MW -3 and <br />MW -4. <br />DRMS Nov 2015: Please provide the information required by Rule 2.04.9 — Soil Resource Information, <br />for the proposed disturbed area of the monitoring wells clusters. <br />GCCE Mar 2016: Additional text has been added to Section 2.04.9 which addresses soil resource information. <br />New map King H-012, Ground & Surface Water Monitoring, is included to show water monitoring locations. <br />Also, new map King II -006A has been added detailing monitor well cluster locations and soil types. <br />
