24HG1 E-0. SXC A-oject Plan <br />A4inor Revision 327- Revision <br />Page7of11 <br />PRE-DRILLING ACTIVITIES <br />Construction and drilling activities will be supervised by a project representative of <br />Mountain Coal Company, L.L.C. Any significant proposed changes in the project after <br />permit approval would be reviewed with the appropriate regulatory agencies before <br />changes take effect. <br />Staging areas to be used by the drilling contractor will be used in a mamier to minimize <br />damage to the vegetation. Any surface disturbance to these sites will be re-graded and <br />seeded to promote rehabilitation. <br />Access routes will be maintained to accommodate full sized 4X4 pickup trucks, ATVs, <br />and required drilling equipment, including but not limited to the following: truck <br />mounted or skid mounted drill rig, air compressors andlor booster, rig-up truck, portable <br />water tanks, boom truck, utility trailer, drill pipe lay-down rack, and crew trucks. <br />Roads utilized in the project will be maintained with water bazs and appropriate <br />sedimentation controls as required during the drilling phase. A D9 bulldozer or its <br />equivalent will be used to prepare the road for travel and assist in mobilizing the drill <br />equipment to the drill sites. Additional equipment expected to be used in opening, <br />maintaining, and reclamation may include arubber-tired backhoe, rubber tired grader, <br />roller compactor and atrack-mounted excavator. <br />Brush removal may occur at the proposed drill sites however, if trees aze encountered, <br />MCC will remove the trees. A drill pad site of approximately 208 ft. x 208 ft. will be <br />constructed to accommodate the drill equipment and drill cuttings sump or mud pits. <br />Drill pads will be constructed only as large as necessary. <br />Topsoil will be stripped, stockpiled, and identified with a sign. Siored topsoil will be <br />placed in a separate pile; the pile will be located outside of drainages and placed in an <br />area where it will be protected from wind erosion; signs identifying the pile as "Topsoil'' <br />will be placed so as to prevent unintended contamination, compaction or use for other <br />than reclamation purposes; alternate sediment controls (slash,- silt fence or straw wattles) <br />will be used; and the pile will be seeded in the first seeding season following its <br />construction using a seed mix that will stabilize erosion. This topsoil will be used in the <br />reclamation phase of the program. <br />Due to the size and number of drill holes several cuttings retention options are being <br />analyzed. These include: <br />• Piping of cutting from a mud pit located in native soil on the drill pad through a <br />slurry pipe across MCC owned property to a temporary impoundment located on <br />MCC owned property. Excess water could be decanted from the temporary <br />impoundment and settled solids removed. <br />
