a <br />• 1. Operator shall comply with applicable requirements of surface management <br />agency, 30 CFR 315. I ~, or approved State program. <br />• MCC has reviewed, and will comply with, all applicable requirements of <br />30 CFR 815.1 and the Colorado Mined Land Reclamation Regulations <br />stated in C.R.S. 34-33-101. <br />2. Install casing and blowout preventers in drillholes in known oil, gas, and <br />geothermal azeas. <br />• The azea neaz the North Fork River is not in a producing natural gas field. <br />Minor gas has been encountered in some of the previous drilling efforts in <br />the area. The proposed drilling will penetrate the Rollins Sandstone, <br />therefore blowout preventers will be used. Casing will be set in each hole <br />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 <br />this section: The hole will be plugged with cement from 50 feet below to <br />30 feet above any coal bed over 4 feet chick and any aquifer. <br />• The remainder of the hole will be filled with a completion mud (bentonite <br />• gel) and drill cuttings or cement to within ~ feet of the surface. A cement <br />surface plug will be set, capped with an appropriately marked brass or <br />aluminum monument, at or 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 <br />logging and/ 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 <br />drilling program. However, MCC does intend to complete this hole as <br />water monitoring well. <br />6. Maps of Project Area <br />• A map of the proposed project area at a scale of 1" = 400', showing all <br />borehole locations, mine mapping, existing roads, pads, and contours are <br />attached. <br />7.
