Mountain Coal has reviewed, and will comply with, all applicable requirements of <br />30 CFR 815.15 and the Colorado Mined Land Reclamation Regulations stated in <br />C.R.S. 34-33-]Ol. <br />2. Install casing and blowout preventers in drillholes in known oil, gas, and <br />geothermal areas. <br />The West Flat Iron area is not in a producing natural gas field. Gas is not known <br />to have been encountered in any of the previous drilling efforts in the azea. Since <br />the proposed drilling will not penetrate the Rollins Sandstone or into the <br />underlying Mancos Shale, blowout preventers will not be used. Casing will be set <br />in each hole as necessary to maintain circulation of cuttings to the surface. <br />3. Drill hole plugging requirements. <br />Each drill hole will be plugged according to the requirements outlined in this <br />section: The hole will be plugged with cement from 50 feet below to 30 feet <br />above any coal bed over 4 feet thick and any aquifer. <br />The remainder of the hole will be filled with a completion mud (bentonite gel) and <br />drill cuttings or cement to within 5 feet of the surface. A cement surface plug will <br />be set, capped with an appropriately marked brass or aluminum monument, at or <br />below ground level. <br />4. Retention of drill logs by applicant. <br />MCC will retain in its files all drill logs and will make them available for <br />inspection by any authorized officer. MCC may conduct geophysical logging and/ <br />or collect core from this project. <br />5. Utilizing drill holes as water monitoring wells. <br />MCC does not anticipate encountering any significant aquifers during this drilling <br />program. MCC does not intend to complete any of these holes as water <br />monitoring wells. <br />6. Maps of Project Area <br />A map of the proposed project azea at a scale of 1" = 500', showing all borehole <br />locations, mine mapping, existing roads, pads, and contours are attached. <br />7.
