to ensure that this subsoil meets the criteria for prime farmland. This data is discussed in Section <br />2.05.4(2)(d) Topsoil Redistribution and Attachment 2.05.4(2)(d) -1. <br />Available topsoil that has not been stripped as of February 2008 was determined. These soils were <br />characterized during the Order 1 Soil Survey (IRI, 1998). Table 2.04.9 -8C shows a summary of <br />the results from those soil pits from the 1998 survey that are in unstripped soil as of February 2008. <br />The topsoil and subsoil salvage calculations for the area west of 2700 Road are given below in <br />Table 2.04.9 -9. This Table includes all areas that have been topsoiled west of 2700 Road, all <br />stockpile inventories and all topsoil and subsoil available from undisturbed areas. It is estimated <br />that for non prime soils, 80% of the thickness value from the 1998 survey will be salvaged for Lift <br />A and Lift B and combined together as a Mixed Topsoil. It is estimated that for prime soils, 93% <br />of the thickness value from the 1998 survey will be salvaged for Lift A and Lift B. It is demonstrated <br />in Section 2.05.4(2)(d) Topsoil Redistribution that the soil volumes available are adequate for the <br />reclamation in all current and future disturbed areas. <br />18. 2011 Topsoil and Stockpile Sampling Program <br />In response to requirements by the Colorado Division of Reclamation, Mining, and Safety and the <br />Office of Surface Mining, WFC has contracted Key -AG to conduct a sampling program of the soil <br />material stockpiled on the Morgan property, the undisturbed soil in place on the south and west <br />sides of the mining area, and the redistributed soil on the eastern side of the Morgan property. <br />The details of this sampling program can be found in Attachment 2.04.9 -10. <br />Revised September 2011 (TR61) 2.04.9 - <br />
