RECLAMATION PLAN This use also applies to all the land on the south and east sides of the Phase 1 mining area which is outside the slurry wall and adjacent to the riparian forest to the south. These areas will be returned to a blend of riparian forest, shrub/scrub wetland, emergent wetland, and with possibly some seasonal (spring and early summer) open water. These land uses are consistent with the character of the surrounding lands and the river corridor. Taken together, these final land uses provide a diverse array of uses which produces a good match between the location of the land relative to other natural and man-made features in the total environment. Industrial and development is intended £or land closest to the highway; water reservoir £or the previous bottomland pasture; wildlife habitat for the land closest to or linked to the river corridor. Materials Handling - Backfilling Exhibit F-1 shows the area that will be backfilled with overburden and the final topography that will be produced in the backfilling. This backfilling will occur in roughly the first third to half of the mining process. This approach allows for disposal of overburden as it is removed, so little overburden storage is needed during the operation. Some of this backfilling process may include the use of a sediment basin for disposal o£ wash fines from the processing plant. In that option, overburden will be used to create the berms needed to contain the sediment basin. However, even if no sediment basin disposal occurs directly into the backfill area, cleanings from other sediment basins will still be disposed of in the backfill area. Either way, fines from washing will be incorporated into the backfill process and will be added to the overburden. In determining the amount of land needed for backfilling, the estimated waste factor for the processing was factored into the total volume of backfill available. The total available backfill volume (total overburden plus wash fines less the volume consumed in constructing the plant site) was then distributed in locations that made the mast sense with regard to final land uses. Because the total volume is an estimate, the actual extent of the backfilling when all backfilling is completed may deviate somewhat from that shown on the map. However, the locations of the backfilling will occur as shown on the map. The backfilling plan does not take into account the redistribution of topsoil. That is an extra amount that will be distributed in locations where revegetation will occur, mainly those lands outside the slurry wall location. Pueblo East Pit Amendment Exhibit E Page 3
