See <br /> Figure 3 for these locations. <br /> Backfilling shall be done as soon as feasible over areas where mining operations have ceased. <br /> Backfilling shall be done in flat lifts with the edges of the mining area graded to a 3:1 slope. <br /> Topsoil shall be placed as soon as feasible over areas where final mining grades have been reached. <br /> After backfilling stockpiles,the locations of stockpiles that are outside of future mining areas shall <br /> be reclaimed according to this plan. Figure 6 shows a proposed final grade for reclamation where <br /> 3.25 feet of backfill and 0.75 feet of topsoil have been filled into mining pits,however the amount <br /> of overburden that will be stockpiled and backfilled is unknown so Figure 6 is only a representation <br /> of an acceptable final grade. <br /> Z:IProjects&Sedgwick County12023 Gravel Pit PermittinglPermit AEC <br />
