In addition to the commitments outlined above, all Bench 1 material excavated on the Morgan <br />property after February 2008 will be salvaged and replaced only on the Morgan property. Section <br />2.05.4(2)(d) addresses the topsoil balance for the entire Morgan property, which is prime farmland. <br />For the 4.76 acres of prime farmland 98A soil in the northwest corner of the WFC property, 3.96 <br />acres of this topsoil was stripped and stockpiled (prior to the determination of prime farmlands in <br />February 2008) to create sediment pond 013. The topsoil was stripped in a combined Lift A and <br />Lift B Mix to a depth of 40 inches. The Mixed Lift topsoil was placed in Stockpiles 3 and 4. The <br />salvage volumes for these 2 stockpiles are shown in Table 2.04.9 -9. <br />16.5 Non Prime Farmlands Soil Stripping Procedures after February 2008 <br />This area basically covers the Benson West property, the Lloyd property and the WFC property <br />north of BB Road and west of 2700 Road. <br />The non prime farmland topsoil stripping procedures for this area is as follows: Since Lift A <br />thicknesses are from 6 -13 inches and Lift B thicknesses are also relatively shallow (8" to 22 "), Lift <br />A and B will be combined into one lift of mixed topsoil because it is very difficult to strip thicknesses <br />of approximately 6 -8 inches with such large mining equipment. The Survcadd thickness averages <br />for the non prime farmland fields west of the pit in February 2008 show 7.1 inches for the average <br />of Lift A and 17.4 inches of Lift B. See Table 2.04.9 -8C. Using 80% of the soil sample average to <br />obtain a stripping average for the area, this results in 5.7 inches for Lift A and 13.9 inches for Lift <br />B. Therefore, the total average stripping thickness for the combined Mixed Topsoil ( Lift A and Lift <br />B) is 19.6 inches. The expected range is from 8 inches to 38 inches. The mine foremen and <br />operators will be trained on the stripping of the mixed Lift A & B, and will know to stop the removal <br />when coarse fragments have a rise from less than 10% volume in Lift B to material that has <br />significantly higher coarse fragments (20 -25 %). In some cases, bedrock will be encountered at the <br />end of Lift B in the non prime farmland areas. <br />An additional amount of suitable subsoil, which is basically the Bench 1 overburden material, will <br />be stripped and placed as shown on Map 2.05.4 -4. The Benson West property basically has <br />(Revised July 2010) 2.04.9 -37 <br />
