significant problem as far as precipitation soaked soils. The likely hood of a dozer working during <br />a severe thunderstorm stacking topsoil is remote. Operationally, that dozer would be pulled out <br />of that work duty to assist the other mining operations such as clearing roads so coal haulage out <br />of the pit could continue. As far as loading, hauling and spreading the topsoil after it has been <br />stacked by the dozer is nothing to be concerned about either. The outer 2 -3" of the pile may be <br />damp but not the interior. Again, no worries or chances of any significant mixing of Lift A with Lift <br />B because after Lift A is stockpiled on Lift B, then the interface is basically covered by several feet <br />of Lift A and the working area is good. <br />WFC does recognize that removing topsoil through saturated irrigation tailwater runoff ditches and <br />the sort could cause some intermixing of the different topsoil horizon(s) or subsoil layers. In this <br />situation, runoff water would be diverted to allow the soil to dry prior to stripping. In all cases, soil <br />removal operations will be conducted in a manner to ensure compliance with Rule 4.06.2(5). <br />17. Soil Volume Availability, February 2008 <br />This subsection is left intact for PR 06 since the topsoil volumes are based on the time frame when <br />the prime farmland soils were first identified, and the volume calculations changed since the <br />stripping procedures changed. An updated soil volume table is included in Section 2.05.4(2)(d) <br />which addresses the status of the soil salvage, stockpiling and replacement based on the <br />conditions as of June 2010. <br />In February 2008, the active pit was centered approximately 2100 feet west of 2700 Rad. <br />Map2.04.0 -2 depicts the location of undisturbed areas to the west, the area occupied by the active <br />pit, and the area between the pit and 2700 Road: those areas partially backfilled, those areas <br />across which Bench 1 substitute subsoil had been previously brought to grade; and those areas <br />where mixed topsoil had already been distributed. It was agreed that the Morgan property would <br />receive the same topsoil and subsoil that was present on the their property prior to mining. The <br />eastern portion of the Morgan property that has had substitute subsoil placement has been tested <br />(Revised July 2010) 2.04.9 -40 <br />
