2.) During the pre-operation inspection conducted on December 29th, 2008, two significant <br />drainages were observed within the permit area. These drainages were not identified on the <br />Mine Plan Map (Exhibit Q. Please include these drainage features on this map. <br />6.4.4 EXHIBIT D - Minim Plan <br />1.) Within the mining plan, it states that the area disturbed would not exceed 20 acres at any one <br />time. Once 20 acres of land has been disturbed, the operator would have to fully reclaim some <br />amount of acreage, and that acreage would have to be released by the Division or the affected <br />area and the financial warranty will need to be adjusted prior to disturbing more than 20 acres. <br />Given the timetable outlined on the mine plan map, is 20 acres enough of an area to be disturbed <br />at any one time? <br />2.) Please indicate what equipment will be used to process the mined material. Also, will any <br />facilities and structures be installed in the processing area to facilitate processing? If so, please <br />indicate their dimensions, and the type and thickness of the material they are built on. <br />3.) Please indicate if there will be a working face or highwall during the mining process. If so, <br />what will be the height and length of the highwall at the time of the greatest amount of <br />disturbance? <br />4.) Under section F of the mine plan it states, "The backsloping and final pit floor will be done at <br />the same time as mining." Please clarify this statement; please explain what it means how it will <br />be done. <br />5.) Also, under section F (i) of the mine plan, it states that there is 0-6 inches of topsoil, and that <br />some overburden will be used to supplement the topsoil and will be used as growth media. In <br />order to maintain the integrity of the topsoil, the overburden should be stripped and stored <br />separately from the topsoil. During reclamation, the overburden should be spread over the graded <br />area first, and then the topsoil should be spread over that. Please indicate the thickness of the <br />overburden that will be salvaged under the topsoil. Please display where the overburden <br />stockpiles will be located on the mine plan map in Exhibit C. <br />6.) Will the maximum pit depth be 18 feet? If not, what will be the maximum pit depth? <br />7.) There appears to be many man made structures within the permit boundary such as gas wells <br />and lines, roads, power lines and fences. Please describe how these structures will be protected <br />from damage during the mining operation. Also, will the operator maintain a setback from these <br />structures? <br />8.) It states in the mine plan that water diversion structures will be installed for storm water <br />management. Please describe these structures. How many of them will there be, what will be <br />their dimensions and where will they be installed? <br />9.) Will the operator use any explosives or blasting techniques during the mining process? <br />10.) During the pre-operation inspection conducted on December 29th, 2008, two significant <br />drainages were observed within the permit area. These drainages were not identified on the Mine <br />Plan Map (Exhibit C) and they are not discussed in the mine plan. In accordance with Rule <br />3.1.6 disturbances to the privileging hydrologic balance of both the surface and ground <br />2
