MINING PLAN <br />highly reliable. Nearly al] of the holes drilled were done for purposes of defining the remediation <br />program rather than defining the sand deposit. <br />BO UNDAR Y DEFINITIONS: <br />Permit Boundary Definition <br />The permit boundary for the Little Johnson Reservoir amendment is an extension of Phase 4e <br />of the existing permit. The boundary does not include all of the Little Johnson area included in the <br />lease, but does include all of the area contained in the former reservoir site. The added area totals 62 <br />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. This boundary was established by considering the amount of <br />land needed to do the actual mining plus additional land needed for topsoil stockpiling. The affected <br />land boundary essentially includes the land in the rectangular cells established on the bottom of the <br />old reservoir plus the southwestern corner of the Little Johnson site. It is not known what function <br />these rectangular cells had, but they are bounded by a low berm which has a narrow road built on top <br />of it. In a few places outside this boundary, where there aze deep depressions or the water table is <br />close to the surface, significant wetlands exist. Disturbance of these wetlands will not occur. <br />Sequencing and Phasing <br />The Little Johnson amendment area, being an extension of Phase 4e, will be operated <br />immediately after the completion of the existing Phase 4e area. Mining will simply proceed further to <br />the east than was originally anticipated. The duration of this extension of Phase 4e will be about one <br />year, depending upon market conditions and the actual quality of the sand encountered. <br />Daniels Sand Pit #2 -Little Johnson Amendment - nn-~s~3-oo~ Exhibit D Page 3 <br />
