Construction activities will be minimized. Existing roads will be used wherever possible. Any <br /> road spurs required will be constructed in such a manner as to minimize erosion and disturbance <br /> to the land surface using a dozer and/or track mounted excavator. The removal of trees will be <br /> avoided where possible. Brush will be disposed in accordance to the agreement with the <br /> landowners. The amount of surface disturbance necessary will depend on the drill site. The <br /> amount of disturbance at each drill site will be kept to a minimum. A pit for the collection of drill <br /> cuttings and fluids will be excavated with a backhoe at each location. The pit will be <br /> approximately 8 ft by 40 ft by 6 ft deep. The pit will be pumped on a regular basis and all fluids <br /> transported to a disposal site at the New Elk Mine. The pit will be backfilled upon completion of <br /> the drilling activity. Present plans call for one pit per drill site. <br /> Drill hole depth and estimated acreage of disturbance for road and site construction is included in <br /> Table 1.2. <br /> Table 1.2: Drill Hole Estimated Disturbance Area <br /> Estimated <br /> Hole no. <br /> Estimated total <br /> Estimated Site Estimated New Estimated Site New Road Disturbance <br /> Area (sf) Road (ft) (Acres) (Acres) (Acres) <br /> N E-01-20 3600 0 0.083 0.000 0.083 <br /> NE-02-20 3600 150 0.083 0.048 0.131 <br /> NE-03-20 3600 240 0.083 0.077 0.160 <br /> NE-04-20 3600 3950 0.083 1.270 1.352 <br /> NE-07-20 3600 5220 0.083 1.678 1.760 <br /> NE-09-20 3600 100 0.083 0.032 0.115 <br /> NE-10-20 3600 0 0.083 0.000 0.083 <br /> NE-12-20 3600 540 0.083 0.174 0.256 <br /> Total 28800 10200 0.661 3.278 3.939 <br /> The irregular terrain precludes making an accurate estimate of the amount of material to be <br /> disturbed. Each pad is estimated to disturb 3,600 square feet. <br /> Approximately 4,150 ft of road will be necessary. All new proposed roads follow previous roads. <br /> The roads are explained in detail in Section 2.05.3 (c). <br /> Drilling activities will include rotary and core drilling. Hole diameter will be 3 inches while <br /> rotary drilling and a 5 inch diameter core when coring. Drilling fluids include air and water with <br /> a mist foaming agent and drilling mud if necessary. All chemicals used will be biodegradable so <br /> as not to adversely impact the surrounding area or any groundwater which may be encountered. <br /> 2.02-2 <br /> TR-75 Revised: 4/16/2020 <br />
