RECLAMATION PLAN <br /> such slopes will be restricted to producing a more even grade. When the mining is completed, <br /> there could be some small valleys and ridges on the slope that need to be evened out some prior <br /> to topsoil placement. In those cases minor amounts of cut and fill will be used on the slope. In <br /> other places where there are larger depressions or perhaps erosion damage that occurred during <br /> mini ackfill will need to be used to correct these small scale defects. The point is,major <br /> backfilli ag <br /> ,I such as creating most of the slope out of backfill,will not be done where the primary <br /> s posed of native material. <br /> There are two locations, however, where major amounts of slope reconstruction will be <br /> required through the use of backfill. These include whatever remains on the slopes on the west <br /> side of the land east of Academy. This primarily involves the slope adjacent to the Academy <br /> Boulevard corridor. Part of this slope is already partially backfilled,but more will be needed. <br /> These slopes are not critical support slopes such as those below the Fountain Mutual Ditch <br /> corridor, so creating them in native material to maximize strength and stability is not as <br /> important. <br /> The second area where considerable backfill will be required is just north of the <br /> J Property,basically the east-west aligned slope in the southeastern corner of the South Area. <br /> Once again though, this is not a critical slope that requires high stability and strength. <br /> The backfilling process will be a combination of lifts and end dumping from the top <br /> along with some cut and fill. The basic form of the slope will be created using lifts of fill <br /> material. This will form a more or less horizontally structured core in the slope. But that slope <br /> will be more or less terraced from top to bottom with an average slope (the line from the top to <br /> the bottom connecting the the terrace lips) of about 3��. . After creating the layered core,material <br /> will be pushed over the top to produce the final surface which will b6 1� Finally,topsoil will be <br /> spread over the top of the final slope. Using this method, greater stability will be achieved in the <br /> backfilled slope than would be accomplished using only an end dump from the top of the slope <br /> approach. The latter creates slopes that are prone to failure. With this slope being north facing, <br /> moisture retention may sometimes be a problem and with an end dumped structure the slope <br /> would be prone to mass failure along the sloping structure lines between each dumping of fill <br /> material. <br /> Few other slopes around the edge of the remaining pit at the end of mining will require <br /> backfilling to much extent. But if that does become necessary in some places, consideration will <br /> be made of the direction the slope faces, the possibility of moisture retention that would increase <br /> mass, and whether failure of the slope might create a rippling of failures even into slopes created <br /> from native material. If the slope is critical, then the horizontal lift only or the combination of <br /> horizontal lift and end dump top surface layer will be used. <br /> Daniels Sand Pit Amendment (2008) Exhibit E Page 12 of 22 <br />
