higher angle slopes and cliffs above the county road. Rock fall and slide rock will be collected from the slope <br /> toe and roadside to assist in county maintenance. <br /> (d) Thickness of deposit to be mined <br /> Material to be mined consists of the upper fractured and weathered surfaces of the basalt outcrop and <br /> loose rock from sheer faces and gullies on the outcrop. The fractured and weathered rock(possible upper 2 <br /> to 4 feet to solid un-weathered bedrock)will be removed off the slopes or scaled off the more sheer faces <br /> as/when necessary. As stated above in (c); some scaling and rock fall mitigation will be done as necessary <br /> on the higher angles slopes and cliffs above the county road. Rock fall and slide rock will be collected from <br /> the slope toe and roadside to assist in county maintenance. Rock-fall cleaned from the road would be <br /> moved to the operations are for temporary stockpiling.The unweathered bedrock is 170' high wall and runs <br /> in variable thickness seams and intermixed with soil.The depth/elevation will be mines to 6600 feet, level <br /> on the mine floor.Approximately 100-120 feet of unweather rock to be removed. <br /> (e) Major components of the mining operation. <br /> 1. Access to the site will be off Moffat County Road 1 using the load owner's private road/ramp, which <br /> was use for the previous site mining operation,to access the site operations area.This access will be <br /> utilized for the duration of the mining activities.The access will also be part of the Moffat County Special <br /> Use Permit. <br /> 2. The 1.34 acre "previously mined area"will be used for temporary process operations and stockpiling. In <br /> the future if demand for rock is needed we will mine under the previous mined area. <br /> 3. There is no shop presently on site.There is a small storage shed and van trailer used for generator,tools <br /> and oil storage. <br /> 4. There are plans to provide for portable crushing or screening plants to process material at this site as <br /> needed. Along with the portable crusher and screening plants a generator with a control/storage van <br /> trailer will be onsite All material will be handled onsite using tracked excavators, bulldozers and front- <br /> end loaders to temporarily stockpile and load to haul trucks. Material stockpiles may be temporary or <br /> may be produced and reduces on a daily basis and will be conveniently located adjacent to active mine <br /> pit areas as excavation activities precede.The 3.25 acre site which is 500 feet to the west of the 5.0 <br /> acres of Moffat County Road 1 will be used to store stockpile materials. <br /> 5. There will be no underground opening such as ventilations facilities or aducts. The operations will be an <br /> open pit operation.The permit boundary is located right next to Moffat County Road 1. We will load <br /> trucks in permit boundary. <br /> (f) Dimensions of any significant disturbance to land surface <br /> 1. Mining will start at and follow the limits of the previously disturbed area (1.34 acre)and will move along <br /> the general existing slope and (rock) high-wall (very slowly) extending the disturbed area to the west <br /> and north. The fractured and weathered rock(a possible upper 2 to 4 feed to solid un-weathered <br /> bedrock) will be removed off the slope or scaled off the more sheer faces as/when necessary. Due to the <br /> nature of the outcrop,the sheer faces and limited annual production from the site the total disturbed <br /> area at end of 20 years would be less than 5.0 acres. (Note:the 20 yr. limit line on Exhibit E Map) <br /> including the current 1.34 previously mined. Slopes would be 3:1 or less when possible, however <br /> remnant high-walls will resemble the current steep to sometimes vertical in places outcrop profile. <br /> 2. Since the bedrock runs in seams the benches are variable. (ex.Seam we are working on now is 60'—5' <br /> wide and the depth is not yet determined.The bench width will be from 60'—15' in width.The depth of <br /> the bench will vary depending on the depth of the seam of the rock.The depth has been 38'-40' in <br /> height and will vary from a straight high wall to a slope because of loose rock and fines at the site.The <br /> hard rock is mined from top of the mine site town in 40' increments. <br />
