Wally Erickson <br />June 28, 2010 <br />Page 6 <br />concerns for affecting groundwater quality is insignificant. During and until bond is <br />released, Wildcat Mining will comply with the Colorado Department of Public Health and <br />the Environment ("CDPHE"), storm water and the industrial discharge permits. Further <br />relevant groundwater and water quality is provided in the response to David Bird's letter <br />dated April 21, 2010. All available data has been provided in the existing permit <br />application. See Attachment 5, Exhibit C-Mine Plan. <br />6. Little Deadwood Creek receives drainage directly from the affected lands. Please <br />provide the information required by Rule 6.3.2(c) for Little Deadwood Creek. <br />Response to Adequacy Issue No. 6: The interconnection of Little Deadwood Gulch <br />and the May Day (and vise versa) is evident. The May Day Mine workings and processing <br />facility are located and will be managed to mitigate future affects to Little Deadwood <br />Gulch. Wildcat Mining has designed surface water control measures, and a discharge <br />structure to control water that potentially migrates across the disturbed mine area. As <br />anticipated to be required in the CDPHE Storm Water Discharge permit and the Industrial <br />Discharge Permit, runoff from the mine will be managed to minimize any potential impacts <br />to Little Deadwood Gulch. See Attachment 6, Exhibit C, Mining Plan and Exhibit E-5. All <br />available data is presently provided in the existing permit application. <br />EXHIBIT C, MINING PLAN, RULE 6.3.3 <br />7. Section 6.3.3(1)(b) of the application indicates that topsoil will be borrowed <br />from undisclosed locations and stockpiled for reclamation purposes. The <br />location of stockpiled topsoil is shown on Figure E-5. Exhibit D commits to <br />topsoil replacement at six inch depth. Pursuant to Rule 6.3.3(1) and <br />63.5(2)(c), please delineate the topsoil borrow locations on the Mine Plan <br />Map. Please note that topsoil borrow locations are affected land, must be <br />located within the permit area and must be addressed by the reclamation plan. <br />Response to Adequacy Issue No. 7: Available topsoil is limited within the project <br />area. Based on the lack of availability of appropriate volumes of topsoil and because <br />Wildcat Mining is committed to minimizing unnecessary environmental impacts from <br />mining operations, at the time it performs reclamation Wildcat Mining will use existing <br />subsoil and alternative material as suitable growth medium. Wildcat Mining will be <br />requesting closure and release of the Lamb Portal reclamation obligations. <br />Pursuant to Rule 6.3.3(1)(e), major components of the mining operation must be <br />described in the mine plan and located on Exhibit E - Map. Exhibit E-3 of the <br />application appears to incorrectly locate the portal at Level 2, shows only one <br />of the two portals at Level 1, does not show the location of the mill facility at <br />Level 1, and does not locate the portal at Level 3. The Level 2 portal is located <br />on the east side of Little Deadwood Creek but is incorrectly located on the west <br />side of the creek on Exhibits E-3 and E-7. Please submit new Exhibits E-3 and <br />E-7, which correctly locate all major components of the mining operation.
