• For the eastern portion of the Morgan property, the average mixed lift stripping thickness was <br />22 inches. The mixed lift is confirmed by the data in the 1998/1999 study, which shows that Lift <br />A on the east portion of the Morgan property is only 17 inches thick. In addition, the bench 1 <br />material was stripped and placed as suitable subsoil to a depth of approximately 34 inches. <br />The areas backfilled as of February 2008 are shown on Map 2.04.9-2. The Morgan property <br />south of BB Road and west of 2700 Road is now considered prime farmland and has therefore <br />resulted in stricter topsoil stripping and replacement procedures for this area. <br />Stripping after February 2008 - Prime Farmland <br />It was agreed with the NRCS in February of 2008, and in a followup phone call among Dan <br />Mathews, Greg Lewicki and the NRCS that the remaining topsoil stripping for the Morgan <br />property (prime farmland) will be as follows: <br />Lift A - strip to color change or 24 inches, whichever is less, where the color change is <br />• defined as from dark brown, which is the normal color of the topsoil, to light tan, which is the <br />distinct color of the subsoil. This color change is consistent and has been used by the operators <br />with no confusion. It is anticipated that the stripping thickness for "Lift A" will be between 7 <br />inches and 24 inches, with an average of 16.0 inches, which is based on the experience with <br />the color change in this area, a 90% recovery of 17.8 inches, as well as the breakdown of Lift A <br />and B in the 1998/1999 soil survey. See Table 2.04.9-5. <br />Lift B - Stripping thickness will be between 20 inches to 60 inches (see Table 2.04.9-5 @ 90% <br />recovery), depending on the location and suitability. It is anticipated that the actual recovered <br />average stripping thickness for Lift B will be 34-36 inches (Table 2.04.9-5 @ 90% recovery), <br />although there is variability due to rock cobbles and color change to near white due to caliche <br />present in the subsoil. For volume calculation purposes, it is anticipated that the average <br />stripping thickness of Lift B is 36.7 inches. The shift foreman will review the soils map showing <br />the soil sample thickness variabilities in the area to be stripped. The foreman will check with the <br />equipment operators to make sure the proper thicknesses are being followed. <br />0 (Revised Nov 2008) 2.05.4(2)(d)-19
