P,ECLAi!AiI"ti ?LAN Roadways will generally remain, except where the road would serve no future • purpose. In those cases, the road would be eliminated along with adjacent mining areas. Backfilling of the mining areas will generally not be done. However, some small valleys may be backfilled as a result of the reclamation; but this would only apply to the small valleys. The larger valleys will be left as they are except where erosion damages must be corrected. Catchment basins and other erosion and sediment control structures will remain after the operation in order to control the run-off from the reclamation areas. This action is considered imperative to inhibiting a renewal of the severe erosion which has occurred in the past. At the end of this exhibit are four cross-sections very similar to the sections included in the mining plan. These cross-sections show the existing surface topography and the final reclamation topography. In most instances the • final reclamation topography will be coincident with the bottom of the gravel, but in some cases it may differ slightly. Also, each section has a vertical exaggeration of from 5 to 10 times. This is indicated beside the line label and is included in parentheses. An indication of "(5v:lh)" means that the vertical scale is exaggerated 5 times the horizontal scale. This results in hills looking like mountains and shallow swales looking like canyons, but this format reveals much more detail than would be visible in a 1:1 scale cross-section. WATER: During the mining process, catchment basins and dams will be necessary in some of the large washes to prevent damage to adjacent land resulting from run- off. The catchments will generally be small and will only hold the run-off water for a short period of time. They are primarily intended to slow the run-off so as to reduce erosional damages. • page 9 of 10 Exhibit E
