PERMANENT MAN-MADE STRUCTURES EXHIBIT L <br />-~ <br />There is 1 man-made structures within 200 feet of the <br />Permit/Affected lands line. It is the County Road 19 (FSR :L00) <br />along the northern section of the permit/affected lands line. <br />The road lies below the lowest mine floor elevation so it wall <br />not be impacted by mining. The USFS allows us to use this :road <br />as access to the site with the understanding that the County will <br />maintain it during the life of the mine. <br />IMPACT ANALYSIS <br />Since the plan is to mine into the hillside and the floor of <br />the mine will be above the road so no mining will take place <br />below the base of the road. Mining this area will not create an <br />instability that could cause damage to the road. A mining setback <br />of 20 feet will be maintained around the site. Along the road <br />where we have located the permit/affected lands line it is n.o <br />closer than 100 feet from the base of the mine face. A near <br />vertical mining face will be used as mining progresses. As the <br />face worked to the mine perimeter away from the road the slopes <br />will be excavated at their final rate of 1.33h to lv. Mini:n.g <br />will be well within the permit boundary so there will be no <br />chance for offsite disturbance due to slope failures. The :~~ottom <br />of the mine will be above the road level. <br />Listed below are the man-made structures within 200 feet of <br />the affected lands. <br />USFS - 1 Road (FSR 100) <br />28 <br />
