Banks and Gesso, LLC <br />Mining area 2 (east of the Public Service Company power line) will be mined in the same <br />way, except it will proceed from east to west. The plant area will be mined last and the <br />processing equipment will be relocated to previously backfilled areas. The process <br />water ponds will be relocated and that area will be mined also. <br />To soil <br />Topsoil quantities sufficient to implement the reclamation plan (approximately 257,000 <br />cubic yards} will be salvaged and stockpiled. Approximately one foot of topsoil will be <br />recovered until there is enough available for reclamation and then after that topsoil <br />material will be handled and used as overburden (or perhaps sold off-site in relatively <br />small quantities). <br />Topsoil will be stockpiled along Nyberg Road for mining area 1 and along the eastern <br />portion of mining area 2 (see Exhibit C-3). Topsoil stockpiles will be seeded with the <br />seed mix contained in the reclamation plan (Exhibit E) to stabilize them and protect them <br />from erosion until the topsoil is used for reclamation. <br />Overburden <br />Overburden (clay and silt) averages approximately 6 feet thick across the property. <br />Overburden material for the entire mine area will amount to approximately 3.4 million <br />cubic yards. This material will be used as reclamation backfill. <br />Overburden removed at the start of mining will be stockpiled at the eastern end of the <br />plant area and in the southern portion of mining area 1. These stockpiles will remain in <br />place until there is enough dewatered pit floor open to start backfilling. After the initial <br />overburden is backfilled into the pit, subsequently excavated overburden will be <br />backfilled directly into the pit. This process of stockpiling overburden and then directly <br />backfilling into previously mined areas will be repeated in mining area 2. An adequate <br />volume of overburden will be stockpiled to backfill the plant area and pond area at the <br />end of mining operations. See Exhibit C3 for approximate overburden stockpile <br />locations. <br />St. Barbara Sand and Gravel Mine 03028 <br />Trans Colorado Concrete q February 19, 2004 <br />
