final report showed that this Bench 1 material was found to be suitable as Bench 1 subsoil <br />substitute. Also, by February of 2008, 7.6 acres of the eastern portion of the Morgan property <br />had received a Mixed Topsoil lift placed on top of the Bench 1 subsoil substitute. As of June <br />2010, this area has expanded to 12.2 acres, with approximately 17 inches of mixed topsoil <br />placed, as shown on Map 2.05.4 -6. <br />After February, 2008, all prime farmland soils have been salvaged in 2 lifts. All prime farmland <br />soils and Bench 1 material excavated from the Morgan property will be replaced on the Morgan <br />property. <br />Map 2.05.4 -6 shows the status of the Morgan Property topsoil and subsoil replacement as of <br />June 2010. This map also shows the topsoil and subsoil stockpile amounts and balance <br />calculations. <br />The Morgan property topsoil replacement is broken down into five different zones of topsoil <br />redistribution. The bases of creating these topsoil lay down zones was to ensure what was done <br />prior to February 2008 will meet the criteria outlined by the NRCS for the restoration of Irrigated <br />Cropland (Prime Farmland) in this area and maximize the quantity of Lift A Topsoil, Lift B <br />Topsoil, Mixed Topsoil and finally Bench 1 Subsoil Substitute to use and optimize the existing <br />topsoil volumes over the largest area possible to grow alfalfa on the land to the highest <br />productivity level. All areas must have minimum combined topsoil and subsoil thickness of 48 <br />inches to qualify as Prime Farmland Soil. <br />DRMS provided WFC with the topsoil and subsoil replacement guidelines for the Morgan <br />property prime farmland. Listed below are the five zones of topsoil redistribution on the Morgan <br />Prime Farmland and how they have, and will, meet those DRMS requirements: <br />• Zone 1 is a 7.81 acre field that currently has 17 inches of Mixed Topsoil overlying 33 plus <br />inches of a Bench 1 Subsoil Substitute. Four inches of Mixed Topsoil will be added to get <br />the total Mixed Topsoil thickness to 21 inches. Total combined soil thickness will be 54 <br />inches. <br />(Revised PR 06) 2.05.4(2)(d) -28 <br />
