RECLAMATION PLAN <br /> (At the end of the Little Johnson Reclamation Plan included in that amendment, there were some <br /> other changes to the existing plan. Those have now been incorporated, as needed, into the <br /> overall reclamation plan for the site. None of the provisions in those sections applied to the Little <br /> Johnson Reservoir area) <br /> THIS CONCLUDES THE SPECIFIC PROVISIONS OF THE RECLAMATION <br /> PLAN FOR THE LITTLE JOHNSON RESER VOIR AREA <br /> Blending the Little Johnson Area into the Rest of the Plan <br /> In the original Little Johnson plan it was thought a reservoir might be built in the mined <br /> out portions. That is no longer the case. So, the gentle west facing slope extending down from the <br /> Little Johnson area to the bottom of the rest of the pit will be the final surface. That leaves only <br /> the south and the north edges of the Little Johnson area to be blended. <br /> The south edge will be a north facin 3: slop that begins at the most easterly end of the <br /> Little Johnson mining area and extends westward where it will simply merge with the 3:1 slope <br /> to the south of the bottom of the pit. This is basically the same approach used in the Little <br /> Johnson reclamation plan,but without the possible reservoir. <br /> The north edge is a bit more problematic. Until the Fountain Mutual Ditch is relocated the <br /> north edge of the Little Johnson area will remain an unreclaimed slope. Once the ditch is <br /> relocated, then the Little Johnson area will be blended with the southeastern corner of the North <br /> Mining Area with a rounded curve as shown on Exhibit F-1. Because this area is north of the <br /> contaminated groundwater plume that is being treated,producing this topography will not have <br /> an effect on the remediation program. <br /> Materials Handling-Backfilling <br /> For the most part,backfilling is not a significant part of the reclamation plan. Most of the <br /> slopes, especially those on the north and east sides will be created in native material. In the <br /> southwestern corner,backfilling will be accomplished by establishing a sediment basin to contain <br /> wash fines produced by the processing of the sand. Many of the current working faces will be <br /> gone by the end of the operation, with only a few remaining. <br /> That said, it is clear that at least some backfilling will be required, even on slopes that are <br /> primarily composed of native material. It is difficult to precisely mine to a specified gradient so <br /> the final slope can simply be topsoiled and seeded. However, any backfilling that will occur on <br /> Daniels Sand Pit Amendment (2008) Exhibit E Page 11 of 22 <br />
