• Consolidation Coal Project, Danforth No. 1 and No. 3, Cultural Resources Survey, <br />Moffat and Rio Blanco Counties. Colorado. <br />• Kennecott Energy: Class III Cultural Resource Inventory for the Colowyo Mine <br />2004-2005 Collom Drilling Program, Moffat County, Colorado, Metcalf <br />Archaeological Consultants, Inc., July 2004 <br />All areas for drilling have had an azchaeological survey. No further work should <br />be required in the drilling areas. <br />VI. Description of Methods to be used to Conduct Coal Exploration and Reclamation. <br />1. Exploration Methods and Types of Equipment <br />The primary exploration method will be rotary and/or core drilling. On most sites, <br />both a pilot hole and an offset core hole will be drilled on the same drill site <br />location. All pilot holes will be logged utilizing geophysical down hole logging <br />methods. <br />Equipment to be utilized will include truck mounted rotary drill rigs, water trucks <br />to supply drilling water, a small sized bulldozer (D4, D6, or D7 class) to construct <br />and reclaim drill locations and access roads, and a backhoe or dozer to construct <br />mud pits for drilling fluids where necessary, and various light duty vehicles to <br />transport personnel and supplies. <br />2. Road and Drill Hole Location Construction <br />Access to the drill sites will be primarily via existing ranch and hunting roads. <br />Road construction to drill sites that cannot be accessed via existing roads will only <br />require clearing brush with no or minimal topsoil removal. Should access road <br />construction be required on side slopes and rugged terrain requiring cut and fill <br />construction, operations will be conducted in a manner that protects both the <br />topsoil resource and the hydrologic balance <br />Only if necessary, topsoil will be removed and stockpiled or windrowed adjacent to <br />the access road under construction for later use during reclamation activities. <br />Where there is potential for erosion and resulting sedimentation, water bars will be <br />included during road construction. Newly constructed creek crossings should not <br />be required, but should existing stream crossings be deemed inadequate, the <br />crossings will be upgraded as necessazy to minimize hydrologic impacts and <br />provide safe access. <br />Drill hole location sites will be about 50 ft, x 100 ft.
