Dry earth <br /> may be added to the water to absorb it. Wet material will be removed and stockpiled on the northeast <br /> corner of our current bench area. <br /> Drilling Schedule: <br /> Drilling will be performed over the course of 10 days on the quarry site. Drilling will take place Monday— <br /> Friday between the hours of lam and 7pm.The crew on site will consist of one senior driller, a driller <br /> helper, and a geologist or geological engineer. <br /> Open Drill Holes: <br /> During the drilling operation, all drill holes at the active drill pad will remain open. Depending upon the <br /> number of holes drilled on each pad location,the number of drill holes open at one time will range from <br /> 1-15. Open holes will be temporarily plugged with a capped piece of PVC pipe 4 feet in length.The pipe <br /> will be inserted into the hole a distance sufficient to keep it locked in place,and the exposed end will <br /> protrude past the surface at least 2 feet. Drilling locations containing open drill holes(temporarily <br /> plugged with PVC pipes)will be marked with traffic cones and sectioned off with yellow caution tape <br /> when drilling personnel are not on site.This includes the time between shifts, weekends, and any time <br /> following the completion of the drilling operations. A total of three drill holes may be kept open for the <br /> purposes of geotechnical analysis for a period of 90 days from the approval of the exploration drilling <br /> request. These holes will remain temporarily plugged with a 4-foot piece of capped PVC pipe and <br /> marked with high visibility traffic cones and caution tape until geotechnical analysis has been performed <br /> or the 90-day time limit has been reached. Once the drilling rig completes drilling operations at a pad <br /> location,the open holes will be plugged before moving to the next pad location,except for those holes <br /> left open for geotechnical analysis. <br /> Plugging and Reclamation: <br /> After the drilling is completed, the drill holes not being left open for geotechnical analysis, will be <br /> promptly plugged and reclaimed in accordance with BLM H-3042-1, chapter 5 and Colorado Code of <br /> Regulations Rule 5.4"Abandonment of Prospecting Drill Holes". Drill holes, without any water present, <br /> will be backfilled with cuttings and capped with a non-metallic plug and 3'of concrete. Cuttings will then <br /> be spread across the top of the drill hole. Should static water be encountered in any of the holes,they <br /> will be backfilled with bentonite pellets to a height of 50' above the static water level and then filled <br /> with cuttings to a height of 3' below surface level.A non-metallic plug will be installed, and the hole will <br /> be capped with 3'of concrete. Cuttings will then be spread across the top of the drill hole. Artesian <br /> water is not expected in the drill holes, but should it be encountered,the following plugging procedures <br /> will be used.The drill hole will be filled with bentonite pellets or concrete to a height of 3' below the <br /> surface level.A non-metallic plug will be installed, and the hole will be capped with 3' of concrete. <br /> Cuttings will then be spread across the top of the drill hole. <br /> Final surface regrading,top soiling,or planting of the drilling areas will not be performed, as the drill <br /> holes are in the active mining area and will be mined through within the next few years. <br /> Post Drilling As-Built Drawing: <br /> Upon the completion of the exploratory drilling, RMR will submit a drawing and a data sheet showing <br /> the location and dimensions of all holes drilled. <br /> 3 <br />
