All environmental standards concerning <br />available topsoil, hydrology and reclamation for this area was <br />included in our recently approved Tecnical Revision #8. <br />• Starting next spring we are proposing. to extend our re#uae <br />conveyor belt 1i54" up the ridge as shown. While the exact design <br />of this belt is now being worked out, it will be very similar to <br />the existing belt structure. When completed, refuse will discharge <br />off the conveyor and will be pushed down the hill by dozers. The <br />refuse will then be spread out on the flat in two foot lifts and <br />compacted according to our approved coal waste disposal plan. <br />As you will <br />on the west side <br />east side. Prior <br />placed in an apps <br />supports will be <br />belt. <br />note, ail disturbance for this <br />of the ridge. There will be no <br />to construction all topsail wi <br />~oved topsoil storage area. The <br />constructed in the same manner <br />conveyor will be <br />activity on the <br />ll~be stripped and <br />conveyor and <br />as the existing <br />Although all environmental aspects of this area were included <br />in TR-08, the increase in bond amount was not addressed. The <br />following calculations indicate what the bond should be increased <br />by to account for this new area: <br />Total Area = 5.3 Acres <br />Topsoil- 12,850 yd3 x 50.85/yd = 510,922.50 <br />Final Grading- 570.00/ac x 5.3 ac = 5 371.00 <br />Revegitation- 51395/ac x 5.3 ac = 5 7,393.50 <br />143 <br />-~ .~. <br />
