uphill climb from the pit floor and probably more expensive than just hauling it away. Thus, hauling it <br /> away and reutilizing it as recycled asphalt might be the very best option. As required by rules, if the <br /> Division of Reclamation,Mining and Safety approves its use as fill for the northwest basin it can be used <br /> there. But doing so without approval could be a violation of State rules unless it is established that the <br /> northwest basin is greater than 3 feet above the high water mark for the groundwater. <br /> A further important consideration is that if it is buried in the northwest basin and the land is <br /> developed for housing, irrigation of lawns and gardens could expose the asphalt to what is effectively <br /> ground water from a high rate of seepage from the surface than would occur if irrigation does not occur <br /> on the overlying surface. Thus, under the development scenario,burying it anywhere on site may not be <br /> appropriate with regard to complying with regulations. <br /> As for the rest of the pit floor, areas identified for revegetation (mainly where there is currently <br /> little or no vegetation) will be prepared for topsoiling with the same approach that was used for the <br /> barren, sandy areas next to the east cut faces. That is,the surface will be graded in a primarily east/west <br /> direction perpendicular to the usual flow of the water which is in a north to south direction. <br /> The area requiring topsoiling an subsequent revegetation on the pit floor is approximately 14 <br /> acres. With a soil depth of 7" it will require approximately 13,000 cubic yards of material from the <br /> North Berm. <br /> As areas are completed with the removal of existing flow channels and the surface is somewhat <br /> ridged in an east/west direction, soil and overburden to a depth of 6" to 8" will be spread across the <br /> existing, treated surface. Care will always be exercised in the preparation of these areas and in topsoiling <br /> to avoid unnecessary damage to adjacent excellent growths of willow and other vegetation, as identified <br /> on Exhibit F-2. <br /> By this time, a lot of the North Berm will have been removed. There will not be much need to <br /> remove more of the berm for reclaiming other areas except for the northwest basin. However, some may <br /> be needed for top dressing of the South Berm slopes. <br /> Vollmer Pit Technical Revision June 2018 Updated Reclamation Plan Page 17 of 26 <br />
