• or from a 4 foot deep soil auger hole. All spoil samples were shipped to Servi-Tech Laboratories <br /> in Hastings,NE for analysis. <br /> The location of each spoil pit is shown on Exhibit 2000-7, Backfill Sampling Location Map. <br /> Laboratory results for the four spoil samples are presented in Attachment 2000-A. The analytical <br /> results indicate all spoil is suitable. No additional grading, special handling, or amendment <br /> application was needed prior to soil replacement. <br /> Soil Redistribution <br /> The topsoil that was used for redistribution was live handled from ahead of the active mining <br /> area to the awaiting backfill area. Phase XII topsoil campaign was done during the Summer of <br /> 2000. A total of 23,030 loose cubic yards were moved. <br /> Soil Thickness <br /> The thickness of soil replaced during 2000 was not verified by sampling. Only one of the <br /> gridded sample locations fell within the 2000 topsoil laydown area. Sample sites for the New <br /> Horizon 2 mining area were selected systematically utilizing a 467 foot by 467 foot grid pattern. <br /> Sites at New Horizon 2 were determined from CAD drawings using distances and azimuths from <br /> established survey points and located in the field by a Chainman 11 distance meter and a pocket <br /> transit. The single sample location will be sampled in the 2001 reclamation year <br /> A 2-3/4 inch bucket auger was used at each site to excavate a pilot hole through the entire soil <br /> strata. An abrupt boundary, defined by color and rock fragment content, typically occurred at the <br /> soil/spoil interface. The replaced soil thickness was measured through the pilot hole <br /> immediately after encountering the spoil. Minor Revision# 44 was approved by DMG in <br /> August 2000. The revision, based on years of extensive sample analysis, allowed for a <br /> reduction in the parameters for which the soil is analyzed <br /> Soil thickness as determined by past sampling is shown on Exhibit 2000-6. Soil thickness <br /> information for each sample site is located on the map. <br /> New Horizon 2 has many different soil thickness requirements as shown on Exhibit 2000-8, <br /> which is in section 2.05.4-4 of the current permit. <br /> Soil Salvage and Storage <br /> All suitable soil has been salvaged ahead of mining at New Horizon 2. Approximately 77,368 <br /> (LIFT 2), 18,391 (LIFT 1), and 52,487 (MIXED) cubic yards of soil are stored in stockpiles at <br /> the end of 2000 as shown on Exhibit 2000-10 (2000 Topsoil Balance Map). The soils were <br /> separately stockpiled by soil types as specified by our permit. <br /> Cover Crop <br /> All topsoil stockpiles have been planted with the approved cover crop seed mixture. <br /> • (d:\data\wpdata\rec-repo\2000recrepo.doc) 2 <br />
