Mud pits will be constructed within the graded pad area. Generally two or three pits are required, <br />with typical pit dimensions of 10 feet x 5 feet and 6 feet deep. The size of the required pits is <br />dependent on the anticipated drilling depths and conditions. Materials excavated from the pits will be <br />stockpiled on the margins of the pad area and used to backfill the pits after the drilling is completed. <br />All drilling fluids will be contained within the mud pits, and all drilling supplies will be contained <br />within the area of the drill pad. Any runoff and associated suspended sediment from the drill pad will <br />be controlled and contained by a perimeter soil berm or silt fence on the downgradient side(s) of the <br />drill pad. <br />Immediately upon cessation of operations, the subsoil will be replaced, with the surface left in a <br />roughened condition. The A and B horizons will then be replaced over the subsoil material (Rule <br />4.21.4(5). <br />Drilling Operations: A rotary drill-rig, capable of rotary drilling and spot-coring, will be utilized for <br />general exploration work. The drill-rig will be atruck-mounted, rubber-tired unit, capable of <br />operating in rough terrain. Support equipment will include, but not be limited to, a water truck, pipe <br />truck and/or pipe trailer, rig-up truck, air compressor, core trailer, and two or three 4 x 4 pickups for <br />the drill-crew and company representatives. For each drillhole, a short section (typically 40-60 feet) <br />of threaded surface casing will be set to stabilize unconsolidated surface materials. Drillholes will be <br />a nominal 6.25 inches in diameter and will vary in depth from approximately 400 to 1,900 feet. The <br />anticipated total depth for each drillhole is identified in Table 2. It is anticipated that the Wadge coal <br />seam and associated roof and floor units will be cored in each drillhole. If other coal seams of <br />interest are penetrated (e.g., Lennox or Sage Creek) they may be cored, as well. Cores will be <br />recovered, examined and logged by a qualified geologist, and core samples may be sent-off for <br />analysis of coal and roof/floor chemistry and characteristics and rock-strength parameters. It is <br />anticipated that the majority of drillholes will extend approximately 70 feet below the Wadge coal <br />seam; most likely they will not extend into the Wolf Creek coal or underlying Trout Creek Sandstone. <br />The primary circulation medium will be water and drilling mud. In the event that subsurface <br />conditions are favorable, air or an air/foam medium may be utilized, as an alternative to mud. Water <br />for drilling will be obtained from stock ponds located on surface controlled by CCR. Drilling <br />contracts will specify that only non-toxic, bio-degradable compounds and additives may be used for <br />drilling muds. <br />At this time CCR does not anticipate "twinning" any of the drillholes. However, if "twinning" of any <br />drillhole becomes necessary, CCR will not "twin" any drillhole until an application for an <br />amendment to the NOI for "twinning" is submitted to and approved by the CDRMS in accordance <br />with Rules 2.02.2(2)(g) and 3.05.2. <br />Geophysical Lo~~in~: On completion of drilling and core recovery, geophysical logging will be <br />completed for each drillhole to obtain additional geologic information. Atruck-mounted geophysical <br />logging unit will be used to obtain, correlate, and store logging information which may include <br />density, gamma, caliper, neutron, focused electric, sonic, verticality, temperature, and conductivity. <br />CCR will retain in its files all drill and geophysical logs for at least one year, and will make them <br />available for inspection by an authorized Division representative. <br />Exploration Maintenance Activities -Other than initial road maintenance to establish good access, it <br />is anticipated that access road maintenance requirements will be minimal, since the majority of the <br />exploration efforts will occur during the dry summer months. Other maintenance requirements will <br />include general housekeeping in active exploration areas and regular inspection and maintenance (as <br />necessary) of drainage structures. <br />Cnw Camp Prajecf -1008 NO/ <br />J//5/08 1 1 <br />
