exploration programs. The drainage and sediment control for the Elk Creek Mine borehole sites <br />will be managed as a small area exemption with alternative sediment control provided by a <br />combination of perimeter sediment control berms/ditches and installation of straw bales, straw <br />waddles or silt fence, etc. to reduce flow velocity and trap sediment. Permit Map 2.05-M4 (4 h <br />sheet) Drainage and Sediment Control Plan provides a typical example of a drill pad lay out. <br />Exhibit 2.05-E3, Drainage and Sediment Control Plan, Section 9, Revised and New SAE's and <br />Alternative Sediment Controls provides typical designs and demonstrations for alternative <br />sediment control and clean water ditch scenarios. Exhibit 2.05-E3, Drainage and Sediment <br />Control Plan, Section 6 contains information regarding mudpit hydrology demonstrations. <br />The boreholes are to be completed in the overburden zone located above the D coal seam. To <br />date, no ground water or aquifers have been encountered in this zone that would require <br />pumping. <br />Bonding/ Reclamation Cost Estimate Considerations <br />As in the past, we are requesting that the Division prepare a cost estimate to complete the <br />reclamation activities. <br />We would like to also note that the boreholes will have the 4" casing cemented in place and there <br />will be no reason to mobilize drilling equipment to ream out the borehole. Consideration for <br />down hole reclamation should only include plugging the casing and sealing with cement using a <br />standard redi-mix concrete truck. <br />Attached please find a proposed public notice which will be published in the Delta County <br />Independent upon notification by the Division that this application is complete. Please contact <br />me at 970-929-5806 if I can provide any additional information or if you have any questions. <br />Sincerely, <br />Zkt <br />ames A.
