Bench 1 Subsoil Substitute <br />By utilizing some excess Lift B material to cover areas east of the existing pit, the area needed for <br />Bench 1 Subsoil Substitute material is lessened. Only Zones 1 and 2 require Bench 1 Subsoil <br />Substitute material. The required thickness is 33 inches over a combined area of 20.05 acres. For <br />this, 88,954 cy is needed. This material was already placed as of February, 2008 and it was actually <br />placed to a far greater thickness. The results of this testing revealed that the Bench 1 Subsoil <br />Substitute was primarily suitable for all tested criteria. Two samples exceeded the conductivity <br />standard by a small amount. This report is included as Attachment 2.05.4(2)(d) -1. It was revised in <br />July of 2008 to include subsoil testing of pH and EC utilizing the paste method. Additional results <br />and discussion have been added to Attachment 2.05.4(2)(d) -1 to address the samples that showed <br />high results. Please refer to Attachment 2.05.4(2)(d) -1 for further discussion. <br />A large stockpile of Bench 1 spoil will be created east of the final 3 mining cuts as shown on Map <br />2.05.4 -6. This stockpile will contain approximately 133,222 cy of Bench 1 spoil which will be used to <br />backfill Zones 3 and 4 prior to topsoil placement. This is not required for the NRCS topsoil <br />thicknesses, but this is being done at the request of the landowner. All Bench 1 material excavated <br />on the Morgan property will be returned to the Morgan property. WFC will make every attempt within <br />reason to see that the upper portion of the Bench 1 spoil will have the best quality. An additional <br />stockpile of Bench 1 of 13,260 cy will be used to reclaim Pond 011, when it is allowed by the <br />Division. <br />Finally, 1.90 acres of the Morgan property will not be disturbed, as shown on Map 2.05.4 -6. This <br />brings the total of all five zones to 107.96 acres of Prime Farmland on the Morgan property. <br />All Lift A Topsoil, Lift B Topsoil, Mixed Topsoil, and Bench 1 Subsoil Substitute for the Morgan <br />property will be tested as described in the soil suitability criteria in Table 2.05.4(2)(d) -1A. All other <br />areas west of 2700 Road will follow the suitability criteria in Table 2.05.4(2)(d) -1 B. <br />12.1.2 WFC Prime Farmland <br />Revised September 2010 (PR 06) 2.05.4(2)(d) -33 <br />
