feet of slotted 5 inch liner pipe will be installed to the bottom of the borehole extending <br />up into the 7 inch casing approximately 50 feet. <br />OMLLC does not plan to complete the boreholes as water monitoring wells. The <br />interval to be drilled above the D seam contains no aquifer. <br />Boreholes will be drilled using rotary drilling methods to the desired depth above the D <br />seam. If drilling muds are necessary to maintain circulation and borehole integrity, muds <br />that are free of metallic compounds will be utilized. Excess drill fluids maybe hauled <br />from the site or left to evaporate. Non-toxic, non-metallic polymers and foams maybe <br />used in the drill fluids to aid the drilling operation. Mud pits remaining after drilling and <br />demobilization is completed will be fenced or otherwise bamcaded to eliminate access by <br />wildlife. <br />All drilling and related operations will be conducted by experienced exploration drillers <br />in such a way as to minimize potential environmental impacts, and will be supervised by <br />a qualified geologist or engineer. Copies of permits will be available in the OMLLC <br />offices. <br />Contacts for the project include: <br />Ken Ball - 970-929-5122 (office) - 720-201-5645 (cell) <br />Doug Allen - 970-929-5122 (office) - 970-946-4797 (cell) <br />Jim Kiger - 970-929-5806 (office) - 970-261-8291 (cell) <br />During drilling, OMLLC will control dust from drilling and related activities, divert and <br />control both natural runoff from disturbed areas and fluid loss from drilling, and will <br />clean-up any trash or debris. If air is utilized as the circulation medium, dust from <br />drilling will be controlled by a flexible shroud at the drill collar. Drill cuttings and <br />portable pits or excavated mud pits will effectively contain drilling fluids as discussed <br />above. <br />All drilling equipment will be equipped with fire extinguishers and shovels in case there <br />is a fire. Oil waste, filters, etc. will be hauled offsite for proper disposal. <br />Site Operation <br />After the borehole casing has been completely set, a skid mounted methane pump will be <br />installed over the well head. The pump will be operated with the methane drawn from <br />the mine, and any excess gas will be vented into the atmosphere. Methane pumps will be <br />operated according to the requirements of the mine and could run for at least one year. <br />OMLLC has no plans to leave the open boreholes in place as future methane gas <br />production wells. <br />The drainage and sediment control system for the Elk Creek Mine gob vent boreholes <br />will be consistent with the previously constructed Sanborn Creek Mine gob vent <br />boreholes. The drainage and sediment control for the Elk Creek Mine borehole sites will <br />
