6 ECM-XX-65 BLM PLAN 3000' 2800' <br />(ECM-04-40) 700' <br />7 ECM-XX-66 BLM PLAN 3000' 0' 1,330' <br />Total 17,200' 2800' 6,900' <br />Most drilling can be conducted with minimal site preparation, since the drill rig can be set-up <br />and leveled using self-contained hydraulic jacks. Where site preparation is necessary due to the <br />need to utilize drilling fluids, a pad having maximum dimensions of approximately 80 feet in <br />width and 130 feet in length will be established. Pad prepazation will involve the use of a <br />tracked dozer or backhoe to establish a level drill site. If topsoil exists, up to 12" will be <br />salvaged and stored in a stockpile(s) located along the side of the pad and marked with a <br />"topsoil" sign. Soil stripping will not occur in areas that have been previously disturbed and <br />little or no soil material remains, typically in aeeas of 30% or greater slopes. The pad sites will <br />be restored to approximate original contour. Shrubs, trees and other organic matter removed <br />during pad preparation may be incorporated onto the regraded surface prior to seeding to <br />enhance reclamation of this disturbed site. <br />Each mud, pit will typically be approximately 20 feet in length, 4 feet in width and 8 feet deep <br />(23.7 cubic yards each). The pits will generally be located in the "cut" portion of the pad for pad <br />stability. The maximum disturbance azea for each drill site is expected to be approximately 0.25 <br />acres. <br />No surface blasting is anticipated. <br />Drilline and Related Activities - 6 '/4" drill holes will be drilled using rotary or auger drilling <br />methods to the depth of the desired coring interval. In order to avoid potential sample <br />contamination, drill holes will be completed to the extent possible with air, air-foam, or water as <br />the circulation medium. If drilling muds are necessary to maintain circulation and drill hole <br />integrity, polymer muds that are free of metallic compounds will be utilized. <br />All drilling and related operations will be conducted by experienced exploration drillers in such a <br />way as to minimize potential environmental impacts, and will be supervised by a qualified <br />geologist or engineer. During drilling operations, water levels and flows in the drill holes (if <br />any) will be closely monitored in order to chazacterize hydrologic conditions in the tazget seams <br />and overlying strata. The interval to be drilled contains no aquifer. Samples of immediate roof <br />and floor rock materials and targeted coal seams will be logged and may be collected during <br />drilling for subsequent analysis. <br />During drilling, OMLLC will control dust from drilling and related activities, divert and control <br />both natural runoff from disturbed aeeas and fluid loss from drilling, and will clean-up any trash <br />or debris. If air is utilized as the circulation medium, dust from drilling will be controlled by a <br />flexible shroud at the drill collaz. Drill cuttings and portable pits or excavated mud pits will <br />effectively contain drilling fluids as discussed above. <br />All drilling equipment will be equipped with fire extinguishers and shovels in case there is a fire. <br />Oil waste, filters, etc. will be hauled offsite for proper disposal. <br />• Page 4 <br />
