<br />Cut and fill estimates of the minesite and office area indicate
<br />that 4,960 yds of soil material are available for excavation.
<br />The final profile on the office and minesite profiles indicate
<br />a need for 5,309 cu yds of fill material to achieve the post
<br />mining contours. This leaves an excess of 600 yds of soil
<br />material.
<br />The 4.9 acre surface facilities area will require 3,900 yards
<br />of soil material to cover the area with a minimum thicKness of
<br />six inches. There are 5,000 cu yds excess soil material from
<br />the waste disposal site. The regrading of the surface
<br />facilites area will result in an excess of 600 yds of material.
<br />This 600 yds along with the 5,000 yds excess from the waste
<br />disposal site will be used to cover the surface facilites area
<br />with a minimum of six inches of soil.
<br />The disturbed areas will be graded to create a maximum slope of
<br />2:1 (see Drawings 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H: Existing and
<br />Final Cross Sections - Cross Sections A, B, C, D, E, F, G, H,
<br />I; J, K, L; Drawings 2I, 2J, 2K, 2L, 2M: Existing and Final
<br />Cross Sections - Cross Sections A1, B1, C1, D1, E1, Ff, G1, H1,
<br />I1; and Drawings 9, 10, 11, and 12: Existing and Final Cross
<br />Sections - Cross Sections 0+50, 1+00, 1+50, 2+00, 2+50, 3+OD,
<br />3+50, 4+00, 4+507. The post-mining topography of the area is
<br />shown on Drawings 5, 6, and 7: Postminirtg Contours and Final
<br />Contours. The Lambert report (March 14, 19857 indicates a
<br />safety factor of 2.8 for the reclaimed area.
<br />The access road will be relocated as shown on Drawings 5 and 6:
<br />Postmining Contours to provide access to the scoria pit located
<br />adJacent to the mining area. The sections of road not
<br />necessary far access to the scoria pit will be removed and
<br />graded to blend the area into the existing topography.
<br />The waste disposal area will be reclaimed after the final
<br />grading of the mining site. This will be done so that any
<br />gxcess spoil material may 6e disposed of in the disposal site.
<br />The waste material will then be covered with two feet of
<br />ion-toxic material. The final contours of the waste disposal
<br />site are shown on Drawing 7: Final Contours.
<br />The waste disposal site will then be seeded with the seed
<br />mixture listed in Table 17: Revegetation Seed Mix. Hand
<br />broadcast seeding methods will be used. Upon successful
<br />revegetation the sediment pond wil be backfilled and seeded
<br />with the Revegetation Seed 1-fix.
<br />The rail loadout structure will be pulled out and the ramp
<br />,pushed back into the area excavated during construction. The
<br />.area will be graded to approximate original contour.
