C- 2010 -089 PAR Part 2 <br />New Horizon North Mine <br />2.04 — INFORMATION ON ENVIRONMENTAL RESOURCES <br />2.04.5 — General Description of Hydrology and Geology <br />3. Please provide a Map 2.04.5(1) which addresses the requirements of 2.04.5(1). <br />5- Jan -2011 <br />Page 2 of 13 <br />4. The narrative presented in section 2.04.5 of the PAP does not appear to provide the requisite <br />information regarding surface water. Please revise this section to include a general discussion <br />of surface water as required by 2.04.5(1). <br />5. Numerous authors and publications are referenced within the text of this section. Please <br />provide a complete list of references at the end of the section in accordance with the <br />requirements of 2.03.3(1). <br />2.04.7 — Hydrology Description <br />2.04.7 1 — Ground Water Information <br />In the second paragraph on page 2 of Section 2.04.7, WFC states that completion diagrams for <br />nine new monitoring wells are contained in Appendix 2.04.7 -1. Actually only "typical" <br />completion diagrams were provided, one for each of three monitoring zones. Please correct the <br />statement on page 2 as follows: "Typical completion diagrams one each for the overburden, <br />coal zone, and underburden well completion monitoring zones are provided in Figure 1 of <br />Appendix 2.04.7 -1." <br />2. The application should contain the specific well completion information for each of the nine <br />new monitoring wells. Table 1 in Appendix 2,04.7 -1 is titled "Proposed Ground Water <br />Monitoring Hole Locations and Depths" and contains "Estimated Monitoring Hole Depths ". <br />This table should be replaced since the wells have been drilled and constructed. Please add a <br />well completion information table to Appendix 2.04.7 -1 that at a minimum contains the <br />following information for each monitoring well: well identification/location, formation <br />monitored, total depth, well casing type and diameter, ground elevation, casing stickup or <br />measuring point elevation, and slotted interval. <br />3. There is a typographical error on page 2. In the second paragraph, WFC states that "...water <br />quality monitoring began immediately upon completion of these 9 holes on October 10, 2010." <br />This should read "October 10, 2008 ". <br />4. Groundwater recharge and discharge are described on page 4 and piezometric level maps are <br />provided for each zone (overburden, coal, and underburden) from which flow direction can be <br />ascertained, but there is no specific description of groundwater flow direction and groundwater <br />discharge is described only in general terms. The Division agrees with the general description <br />provided in that the overburden strata is the primary source of discharge to the drainages of <br />Tuttle Draw (to the south) and Coal Canyon (to the west) and that the permeability and porosity <br />will increase with spoil replacement. <br />
