MINING PLAN <br /> B O UNDAR Y DEFINI TIONS: <br /> Permit Boundary Definition <br /> The permit boundary for the Little Johnson Reservoir amendment is an extension of Phase4e <br /> THE SOUTH AREA. of the existing permit. The boundary does not include all of the Little Johnson <br /> area included in the lease,but does include all of the area contained in the former reservoir site. The <br /> added area totals 62 acres. <br /> Affected Land Boundary Definition <br /> The affected land boundary includes an area considerably smaller than the Little Johnson <br /> permit boundary extension of Phase-4e THE SOUTH AREA. This boundary was established by <br /> considering the amount of land needed to do the actual mining plus additional land needed for <br /> topsoil stockpiling. The affected land boundary essentially includes the land in the rectangular cells <br /> established on the bottom of the old reservoir plus the southwestern corner of the Little Johnson site. <br /> It is not known what function these rectangular cells had,but they are bounded by a low berm which <br /> has a narrow road built on top of it. In a few places outside this boundary, where there are deep <br /> depressions or the water table is close to the surface, significant wetlands exist. Disturbance of these <br /> wetlands will not occur. <br /> Sequencing and Phasing <br /> The Little Johnson amendment area,being an extension of Rhase4e THE SOUTH AREA, <br /> will be operated immediately after the completion of the existing Phase 4e area IN CONJUNCTION <br /> WITH THE NORTH AND SOUTH AREAS. Mining will simply proceed further to the east than <br /> was originally anticipated. The duration of this extension of Phase-4e THE SOUTH AREA will be <br /> about one year, depending upon market conditions and the actual quality of the sand encountered. <br /> METHOD OF MINING: <br /> TOPSOIL SALVAGE- As described in the Soils Information (Exhibit I), the soil in the <br /> Little Johnson area is atypical. The soil is a blend of the original soil plus the fine sediment that <br /> accumulated in the bottom of the reservoir. From the drill logs it appears the soil is deepest in the <br /> middle and eastern portions of the affected land. Because the water table rapidly rises in the eastern <br /> portions of the affected land area it is entirely possible that removal of the soil alone will expose <br /> Daniels Sand Pit Amendment (2008) Exhibit D Page 12 of 28 <br />
