coordinate with the CDOW to keep specific gates locked to preclude public access, and to avoid areas <br />of critical winter range. CCR will also coordinate with the CDOW to minimize potential impacts to <br />grouse leks and active raptor nests during critical use periods. <br />Site Development- Exploration Access: Primary access to the proposed exploration area will be via <br />existing Routt County Road 27, southeast of Hayden, Colorado. As shown on Map 1, existing Routt <br />County Roads 27, 27A, 51 C and 51 D, as well as, existing graveled coal mine haul roads and <br />unimproved ranch roads and jeep trails will be utilized to access exploration drill-sites within the <br />exploration area. CCR has specifically sited proposed drill-sites adjacent to existing roads and in <br />areas of previous disturbance in order to minimize any new disturbance associated with the proposed <br />exploration activities. <br />There may be limited instances where direct access to a proposed drill-site is not possible using the <br />existiug road network. In these circumstances, drilling equipment will be moved overland the short <br />distance between the existing roadway and proposed exploration pad without constructing a new <br />road. <br />Site Develonment -Drill Pad Construction: Maximum drill pad dimensions will be 100 x 100 feet. <br />Pad construction will begin with removal of existing topsoil material for use in reclaiming the pad. <br />Available soil material will be removed to a maximum depth of approximately 18 inches and <br />stockpiled on the uphill side of the pad. Stockpiled material will be clearly marked with a "soil <br />material" sign. Runoff and sediment contributions from the soil material stockpile will be controlled <br />through placement of a silt fence or soil berm (approximately one foot in height) downgradient from <br />the stockpile. After stripping and stockpiling the available soil material, minor grading will be <br />completed to establish the drill pad and accommodate the drilling and support equipment. The <br />selected drill-sites are located on gentle slopes or bench areas to minimize grading requirements. <br />Mud pits will be constructed within the graded pad area. Generally two or three pits are required, <br />with typical pit dimensions of 10 feet x 5 feet and 6 feet deep. The size of the required pits is <br />dependent on the anticipated drilling depths and conditions. Materials excavated from the pits will be <br />stockpiled on the margins of the pad area and used to backfill the pits after the drilling is completed. <br />All drilling fluids will be contained within the mud pits, and all drilling supplies will be contained <br />within the area of the drill pad. If "twinning" of any drill hole becomes necessary, it is anticipated <br />that the additional drilling would occur within the limits of the previously constructed drill pad. Any <br />runoff and associated suspended sediment from the drill pad will be controlled and contained by a <br />perimeter soil berm or silt fence on the downgradient side(s) of the drill pad. <br />Drilling Operations: A rotary drill-rig, capable of rotary drilling and spot-coring, will be utilized for <br />general exploration work. The drill-rig will be struck-mounted, rubber-tired unit, capable of <br />operating in rough terrain. Support equipment will include but not be limited to a water truck, pipe <br />tn/ck and/or pipe trailer, rig-up truck, air compressor, core trailer, and two or three 4 x 4 pickups for <br />the drill-crew and company representatives. For each dril[hole, a short section (typically 40-60 feet) <br />of threaded surface casing will be set to stabilize unconsolidated surface materials. Drillholes will be <br />a nominal 6.25 inches in diameter and will vary in depth from approximately 425 to 1,475 feet. The <br />location and anticipated total depth for each drillhole are identified in Table I. It is anticipated that <br />the Wadge and Wolf Creek coal seams and associated roof and floor units will be cored in each <br />drillhole. [f other coal seams of interest are penetrated they may be cored, as well. Cores will be <br />recovered, examined and logged by a qualified geologist, and core samples may be sent-off for <br />analysis of coal and roof/floor chemistry and characteristics and rock-strength parameters. It is <br />anticipated that the majority of drillholes will extend approximately 70 feet below the Wolf Creek <br />coal seam, but none will extend into the Trout Creek Sandstone, The primary circulation medium <br />will be water and drilling mud.
