The following information is relative to the Reclamation Plan (Exhibit E) in terms
of acreage within each mining cell of the corresponding phases and t:he methods
of reclamation discussed therein.
(1} Within Phases A, B and•C there are approximately 5 propose;d mining
cells. Each of these cells contains 10 acres. As discussed in Exhibit E,
topsoil and overburden will be placed in berms along the eastern
perimeter and between the phases. The method for replacement is to slot-
doze the material in appropriate sequence over each cell upon cessation
of mining.
The material will pushed downhill from the eastern boundaries over the
mid-length of the cells. Material from between the phases will be replaced
in the same manner to provide appropriate cover with minimal material
handling. It is estimated that an average of 1.5 feet of overburden and 6
inches of topsoil will be replaced. Thus the approximate volume of
material to be handled is {(10 acres x 43,560 s.f./ ac. X 2 ft.) / 27 c.f./ c.y.}
= 32.3K c.y. The maximum length far material to be pushed idozed) in this
manner is 400 ft.
Between the process of replacement of the overburden and topsoil rough
grading of the cell will occur. Once the topsoil is in place, final grading will
take place, including the shaping of the 3:1 maximum slope along the
eastern perimeter.
Following final material replacement, the cells will be reseeded as
discussed in Exhibit E.
Phase D is proposed to be reclaimed as a reservoir. Reclamation of this
phase will involve the replacement of overburden if necessary and
adequate topsoil (4 - 8")along the banks of the reservoir at a slope not to
exceed a 3:1 ratio. The perimeter the proposed 4-6 acre re:>ervoir is
estimated to be approximately 1,5D0 feet in length depending on the final
shape of the reservoir. Thus the volume material to be handled in this
phase is approximately {( 1,500 it. x 6 f.t slp. dist. x .5 ft.) /:27 c.f./c.y.} _
170 c.y. It is expected that some rough grading of the reservoir
embankment will precede the replacement of topsoi! and final grading take
place prior to reseeding as discussed in Exhibit E.
Phase E, as described in Exhibit E contains poor surface :;oil. The method
of reclamation is proposed to involve the replacement of 1 - 2' of
conditioned, upper zone overburden over this phase. This phase contains
approximately 11.7 acres. However, the area to be mined will not exceed
ten acres as discussed earlier. The process of overburden replacement
