<br />The location of each spoil pit is shown on Exhibit 2003-7, Backfill Sampling Location Map. <br />The analytical results indicate that all spoil is suitable. No additional grading, special <br />handling, or amendment application is needed prior to soil replacement. <br />Soil Redistribution <br />The topsoil that was used for redistribution was live handled from ahead of the active <br />mining area to the awaiting backfill area. Because the material is moved by mine <br />equipment and is scheduled amongst the other mining functions, discrete topsoil <br />campaigns as done in the past are no longer conducted. <br />Soil Thickness <br />The thickness of soil replaced during 2003 was verified by two sample sites. Sample sites <br />for the New Horizon 2 mining area were selected systematically utilizing a 467 foot by 467 <br />foot grid pattern. Sites at New Horizon 2 were determined from CAD drawings using <br />distances and azimuths from established survey points and located in the field by a <br />Chainman II distance meter and a pocket transit or a handheld GPS unit. <br />A 2-3/4 inch bucket auger was used at each site to excavate a pilot hole through the entire <br />soil strata. An abrupt boundary, defined by color and rock fragment content, typically <br />• occurred at the soil/spoil interface. The replaced soil thickness was measured through the <br />pilot hole immediately after encountering the spoil. Minor Revision # 44 was approved by <br />DMG in August 2000. The revision, based on years of extensive sample analysis, allowed <br />for a reduction in the parameters for which the soil is analyzed <br />Soil thickness as determined by past sampling is shown on Exhibit 2003-6. Soil thickness <br />information for each sample site is located on the map. Attachment 2003-A lists the topsoil <br />chemistry. <br />New Horizon 2 has many different soil thickness requirements as shown on Exhibit 2003-8, <br />which is in section 2.05.4-4 of the current permit. This shows the type and area of the <br />reclaimed land. <br />Soil Salvage and Storage <br />All suitable soil has been salvaged ahead of mining at New Horizon 2. Approximately <br />77,368 (LIFT 2), 146,937 (LIFT 1), and 45,647 (MIXED) cubic yards of soil are stored in <br />stockpiles at the end of 2003 as shown on Exhibit 2003-10 (2003 Topsoil Balance Map). <br />The soils were separately stockpiled by soil types as specified by our permit. <br />r1 <br />~J <br />(F:\eng\data\wordlann reclaim rpt\2003recrepo.doc) <br />
