2. Topsoil Replacement <br />Topsoil is very scarce on this site, and varies from 0-6 inches. To provide additional plant growth <br />material, fines will be mixed in with the salvaged topsoil. The first area to be topsoiled will be <br />the center pivot field. This topsoil will come from Topsoil Stockpile #2. The side slopes will be <br />topsoiled as they are regraded. The remainder of the site will be topsoiled at once because the <br />entire pit floor is needed for product stockpiles and operations. Topsoil will be handled with <br />scrapers. Care will be taken to recover as much topsoil as possible. All topsoil replacement areas <br />will be scarified to help root growth prior to topsoiling. <br />Table F.-1 Reclamation nuantities <br /> <br />Area Area to be <br />Topsoiled Topsoil <br />Required (CY) <br />Mining Area 1 26.06 13,874 <br />Mining Area 2 58.02 30,890 <br />Mining Area 3 6.83 3,636 <br />Mining Area 4 10.54 5,611 <br />Surrounding Area 7.12 3,791 <br />Total 101.45 76,182 <br />These topsoil amounts were calculated using an average replacement thickness of 4 inches. This <br />is the combined thickness of topsoil and some reject fines. <br />3. Haul Roads and Access <br />The access road down into the pit will remain after mining to allow access for the landowner to <br />the irrigated pasture. The access roads to the north and west of the pit will be topsoiled and <br />seeded because they will no longer be needed. See Map C-213. <br />4. Revey-etation Plan <br />For flat areas which will see the most compaction, the soil will be disked. Due to mild grade, <br />seed can be drilled in the irrigated pasture areas. For the dry rangeland slopes, broadcast seeding <br />will be used. The rangeland mix was prescribed by the NCRS. Certified weed free mulch will <br />Cugnini Pit, November 2009 E-2
