9.0 General Topsoil Handling & Placement Procedures Prior to February 2008 <br />The mine was initially started in a box cut in the southeast corner of the permit area. Mixed Lift <br />Topsoil and Lift A topsoil was placed in Stockpiles C, D, E and H as shown on Map 2.05.4-9. <br />Additional stockpiles were created as the mine advanced. Once these stockpiles were created, <br />almost all additional topsoil was excavated and directly placed on regraded spoil behind the <br />active pit. <br />Prior to February 2008, some topsoil was stripped and replaced on the reclaimed area in a single <br />lift and other areas (the majority) was stripped in 2 lifts and replaced in 2 lifts. A minimum of <br />three feet of Bench 1 material was placed beneath the topsoil. Map 2.05.4-4 shows the actual <br />topsoil material replacement thicknesses for the permit area. All of the area east of 2700 Road <br />was re-topsoiled prior to February 2008. The February 2008 date is important since the topsoil <br />on the eastern portion of the Morgan property was stripped in a single lift up to that date. <br />Also, a small area of 98A soil was stripped for the construction of Pond 013. This topsoil was <br />ruled to be prime farmland soil by the NRCS, and had to be handled accordingly. The topsoil <br />was stripped in a mixed lift and was placed in Stockpile 4. <br />Details of historic soil salvaging can be found in Section 2.04.9. <br />9.1 Morgan Property Soil Augmentation Plan <br />In order to satisfy requirements of legal settlements with the Morgans, 32,800 CY of topsoil <br />from the ERMR-Johnson and Benson property will be transferred to the Morgan Property. This <br />topsoil will come from stockpiles on the aforementioned properties. This ERMR Extra topsoil <br />will be placed on the Morgan Property as additional subsoil. The quantities and thickness of the <br />ERMR Extra can be seen on Map 2.05.4-6 and are discussed in subsection 12.0. <br />To make up for the removal of topsoil (ERMR Extra) from the ERMR-Johnson property, <br />stockpiled Bench 1 material was selected to place below the topsoil and create a total soil depth <br />of 25 inches. This Bench 1 material was studied by experts and was found to be usable as <br />subsoil. A report to this effect can be seen in Attachment 2.05.4(2)(d)-3. This Bench 1 subsoil <br />will be sampled for quality as it is placed, in the same fashion as the Mixed Topsoil that will be <br />placed atop of it. The Bench 1 will be rock picked after placement to minimize coarse fragment <br />content. Map 2.05.4-9 shows the material balance of the Bench 1 and Mixed Topsoil placement <br />on the Johnson property (Zone 6 & 7). <br />July 2018 (TR -84) 2.05.4(2)(d)-11 <br />
