<br />intended as phases but as vertical steps so that the 200 vertical feet can be mined in <br />stages to gradually lower the core of the Irorseslroe in safer vertical steps and if level <br />area is available, material is to be stored in Zones 3 and 4. However, if necessary, <br />material and processing could be done on upper levels as more areas are leveled. <br />There is approximately a 200 foot difference in elevation between the highest area to be <br />left at the top of the ridge and the elevation of current Zone 3. Tlris will create only <br />five total benches top to bottom. The benches will nm approximately level <br />horizontally. They will be tipped slightly to the center of the pit at approximatly 2% so <br />that runoff will spill gently all along the bench. The nmoff will not be gathered until it <br />reaches the mining level where it can be diverted as required while mining is in <br />progress. It will be gathered at the bottom of the slope when mined out in a horseshoe <br />shape and brought to settlement areas in the same vicinity they are currently along with <br />new ones shown on the reclamation map. <br />The powerline will need to be moved about halfway through the operation. The <br />cost is to be covered by Gunnison Gravel. We have spoken with Gunnison County <br />Electric Association about the evenhial removal and re-alignment. Their suggestion <br />was to move the line to the west boundary of the site then turn due east and follow the <br />northern boundary until it meets the existing line at the 7,545 level. We will leave a <br />road along the western and northern boundary for access to the powerline. Some <br />shorter islands may exist before the line is moved. <br />All roads will be within the 33.16 acre leased area. <br />Washing, concrete, or asphalt hatching will be done in Zone 3 or 4 until the <br />7,570 level expands west and south. Crushing, however, may occur wherever enough <br />level work area esists. <br />C~urently water containment is done in tanks, however, if settling ponds might be <br />required in the future they would probably occur in Zone 4 or possibly Zone 3. As the <br />7,570 level grows west and south, settling ponds could be placed inside the horseshoe <br />drainage ditch. These ponds would be a minimum size as required by the State of <br />Colorado. <br />The fuel tanks shown in the old permit area have been removed several years <br />ago. The scales and scale house remain. Less than 100 gallons of oil will ever be <br />stored on site and it will be safely inside the dry van storage trailer. No bulk fi~el will <br />be stored on site. Mobile skid tanks will be used only when portable equipment is <br />being used on site. Otherwise service trucks will fuel mobile equipment. The scales <br />and scalelrouse are portable and can be loaded with a small crane. The scale <br /> <br />
