EXHIBIT L -RECLAMATION COSTS (6.4.12) <br />The following information is relative to the Reclamation Plan (Exhibit E) in terms <br />of acreage within each mining cell of the corresponding phases and the methods <br />of reclamation discussed therein. <br />(1) Within Phases A, B and C there are approximately 5 proposed mining <br />cells. Each of these cells contains 10 acres. As discussed in Exhibit E, <br />topsoil and overburden will be placed in berms along the eastern <br />perimeter and between the phases. The method for replacement is to slot- <br />doze the material in appropriate sequence over each cell upon cessation <br />of mining. <br />The material will pushed downhill from the eastern boundaries over the <br />mid-length of the cells. Material from between the phases will be replaced <br />in the same manner to provide appropriate cover with minimal material <br />handling. It is estimated that an average of 1.5 feet of overburden and 6 <br />inches of topsoil will be replaced. Thus the approximate volume of <br />material to be handled is {(10 acres x 43,560 s.f./ ac. X 2 ft.) / 27 c.f./ c.y.} <br />= 32.3K c.y. The maximum length for material to be pushed (dozed) in this <br />manner is 400 ft. <br />Between the process of replacement of the overburden and topsoil rough <br />grading of the cell will occur. Once the topsoil is in place, final grading will <br />take place, including the shaping of the 3:1 maximum slope along the <br />eastern perimeter. <br />Following final material replacement, the cells will be reseeded as <br />discussed in Exhibit E. <br />Phase D is proposed to be reclaimed as a reservoir. Reclamation of this <br />phase will involve the replacement of overburden if necessary and <br />adequate topsoil (4 - 8")along the banks of the reservoir at a slope not to <br />exceed a 3:1 ratio. The perimeter the proposed 4-6 acre reservoir is <br />estimated to be approximately 1,500 feet in length depending on the final <br />shape of the reservoir. Thus the volume material to be handled in this <br />phase is approximately {( 1,500 ft. x 6 f.t slp. dist. x .5 ft.) ! 27 c.f.lc.y.} _ <br />170 c.y. It is expected that some rough grading of the reservoir <br />embankment will precede the replacement of topsoil and final grading take <br />place prior to reseeding as discussed in Exhibit E. <br />Phase E, as described in Exhibit E contains poor surface soil. The method <br />of reclamation is proposed to involve the replacement of 1 - 2' of <br />conditioned, upper zone overburden over this phase. This phase contains <br />approximately 11.7 acres. However, the area to be mined will not exceed <br />ten acres as discussed earlier. The process of overburden replacement <br />,~ <br />
