Reclamation Unit: Northwest Basin. At present this area is a shallow bowl bounded by rather high <br /> and very steep slopes and walls on the north and west sides. The east and south are open but have a <br /> gentle rise. The bounding slopes and walls are mostly composed of unmined material capped with soil <br /> and overburden about 10'to 15'deep. It appears that this area was originally a small hill where most of <br /> the eastern side of the hill was excavated for sand and turned into the location for the scale, scale house, <br /> some small concrete pads, and a well head for water. <br /> Minimal reclamation for this area includes removal of the facilities such as scale, scale house, <br /> etc., extension of the well head to a higher top point if the well is to be used in the future or capping and <br /> abandoning the well if it is not to be used, and then cutting down approximately 1/3 to 1/2 of the <br /> bounding walls and pushing that into the basin to create 3:1 slopes. <br /> After removal or destruction of the scale house and the like,the high walls and slopes on the <br /> north and west side can most effectively be reduced by working from east to west on the northern part <br /> of the east/west North Berm, turning the corner and doing the same to the west side wall. However, <br /> there are abundant nearly mature sized pinyon pines on the sides of the walls opposite the basin. These <br /> will be removed. These will not be disposed of in the created final slope and filling of the basin as that <br /> would likely produce irregularities and possibly unstable land on top of where the trees are decaying and <br /> creating voids in the subsoil. If desired, the entire remaining hill can be pushed into the northwest basin, <br /> but that is not required so long as at least 3:1 slopes are created where there currently is nearly 1:1 <br /> slopes. <br /> Optionally, the rise to the east of the basin where asphalt piles currently sit, can be graded and <br /> also pushed into the basin to create a more level final topography in the northwest corner. But it can also <br /> be left in place and simply topsoiled and planted. If approved,the asphalt can be included in the <br /> reduction of the rise, but approval of using the asphalt for fill is a separate issue. <br /> The approach to reducing the bounding walls and high slopes by working from the east seems <br /> much easier than trying to reach the top of the west wall from its south end. The south end is also a very <br /> steep and high wall that is mostly composed of the remains of the hill that was here. Reaching the top of <br /> that area from the south would be very difficult while simply extending the slope reduction from the east <br /> and working around the corner seems much easier, especially if the acquisition of soil and overburden <br /> for the reclamation of the rest of the pit is being done in an east to west direction. <br /> After the 3:1 slopes are created they will be seeded with the revegetation seed mix. This, in <br /> combination with not having the native sand deposit exposed, should result in a protective cover for <br /> Vollmer Pit Technical Revision June 2018 Updated Reclamation Plan Page 20 of 26 <br />
