MINING PLAN <br /> screen. Some backfilling has occurred on the east side of this area, but it is not expected that as much <br /> material will be removed from here as originally anticipated. Much of this high bank is in the <br /> highway right of way. Any further extraction will only extend as far as the highway right of way,but <br /> not into the right of way. The permit boundary has been adjusted accordingly. For the most part, <br /> what is present on this high bank will remain into the foreseeable future. Most of the activity along <br /> this bank will involve reclamation rather than extraction. One of the difficulties with the original <br /> (1992/1993)plan was a lack of permission to remove the sand within the right of way. Pursuing that <br /> permission has now been abandoned. Therefore, the plan for this area has been adjusted to limit <br /> extraction to land outside the right off and merge the topography created with the backfilling <br /> already performed on the east side of this high bank. When completed, this area will be a rounded <br /> ridge. For further details,please refer to the Reclamation Plan, Exhibit E. <br /> NORTH AREA MINING <br /> The north mining area east of Academy Boulevard presents some complexity in the mining <br /> procedures. These complexities mainly involve merging the mining area with the new highway <br /> corridor, creation of the new corridor for the Fountain Mutual Ditch, and connecting the South Area <br /> with the North Area through removal of the current ditch route. Clearly, connecting the North and <br /> South Mining Areas will require relocation of the ditch first. But before the ditch can be relocated <br /> the sand north of the new ditch route and the south edge of the highway will need to be fully <br /> excavated and completed. Once the ditch corridor is created and the ditch relocated, the rest of the <br /> mining south of the new ditch route will be a fairly simple processes of removing the sand and <br /> connecting the North and South Mining Areas. In the southeastern corner of the North Mining Area, <br /> a connection needs to be created that will link the North Mining Area with the Little Johnson <br /> Reservoir mining area. Of course, this connection also cannot occur until the ditch is relocated. <br /> In addition to these complexities, there is the matter of producing a sufficient diversity of <br /> sand grades to provide the needs of the market place. Because the sand deposit is not uniform in <br /> texture in the vertical column, too much emphasis on higher level sands would result in a reduced <br /> production of the more coarse deeper sands. Thus, although it would be preferable to simply launch <br /> into creating the ditch corridor before mining any deeper, that would likely result in the production of <br /> excess fine sand with a reduction in the production of coarser sand. To remedy this likely bias toward <br /> finer sand, some mining of deeper sands adjacent to the current pit will still be required. This will <br /> result in a reduction in the rate of production of new ditch corridor thus extending the period of time <br /> before the ditch can actually be relocated. <br /> Daniels Sand Pit Amendment (2008) Exhibit D Page 20 of 28 <br />
