Paul Banks and Associates, LLC <br />The Pierre Shale directly underlies the sand and gravel deposit on the property. This <br />geologic unit is well known for its relative impermeability and is very suitable bedrock for <br />impounding water. <br />Reclamation Materials <br />Earth materials to be used in reclamation are salvaged topsoil, overburden, processing <br />waste and sediment pond fines. <br />One foot of topsoil will be removed and stockpiled until an amount adequate to <br />implement the reclamation plan has been recovered. After an adequate amount has <br />been recovered, topsoil will be treated as overburden. Some topsoil may be sold off -site <br />and some may be placed directly on areas to be reclaimed immediately after stripping <br />without being stockpiled. The total amount of topsoil needed for final reclamation is <br />approximately 257,000 cubic yards. <br />An average of six feet (6 ft.) of overburden is present across the area to be mined. The <br />total overburden removed and to be used as reclamation backfill is approximately 3.4 <br />million cubic yards. <br />Processing waste and sediment pond fines are estimated to amount to 1.2 million cubic <br />yards, and these materials will also be used as reclamation backfill. <br />Reclamation Timing <br />Reclamation (i.e. grading, topsoiling, and seeding) will begin as soon as an adequate <br />amount of land has been backfilled to approximate pre- mining grade. This will occur in <br />the northwest portion of mining area 1. <br />Reclamation will proceed concurrently from this time forward until the backfill area is <br />complete. Pit slopes will be concurrently reclaimed once mining and earthmoving have <br />ceased in the area of the slopes to be reclaimed. This process will be repeated in <br />mining area 2. <br />St. Barbara Sand and Gravel Mine <br />Pete Lien & Sons, Inc. 13 <br />10031 <br />June 15, 2011 <br />
