"rhe current plan for reclamation of the benches calls for grading of fill at the <br /> outside perimeter of the tench to achieve a moderate slope, using the materiaP-- <br /> thus excavated to construct a buttress along the toe of the cut, then seeding the <br /> area which has been graded. _ <br /> George Wear says that the downsiopes themselves have not been inciuci4d in <br /> the calculations of acreage to be vegetated on the grounds that these are pre- <br /> law disturbances, and tho practical consideration that it would be infeasible in <br /> any case. <br /> The grading concept tested at the #4 mine area included installation of <br /> ,,catchment basins at the base of the slope for sediment control. Sediment fills in <br /> behind the catchment basins, and is later seeded. This concept could possibly <br /> be employed as part of reclamation at other bench areas, below other <br /> downsiopes. <br /> Backfilllgrading <br /> 'The current approved plain of the (MLRD) permit calls for backfill of material at <br /> the hillside behind the praparation plant. The material anticipated for backfill <br /> includes coal washer refuse which was to have been stockpiled from the last <br /> coal washer opeations, and rubble from the foundations of the buildings in the <br /> preparation plant area. Additional soil was to be "borrowed" from some other, <br /> unspecified source. We believe the transport of material for this purpose is <br /> waste of money, ai id would create a less stable hillside. Further, there are <br /> scheduling problems in that we would like to cover most of the Sutey pile, which <br /> would be the source of washer refuse material, next year, and would like to start <br /> on this hillside behind tho preparation plant either next year or in 1994. The <br /> foundations from the buildings of the preparation plant area will not be available <br /> for this backfill use for several years. Further, the "borrow" area would create <br /> substantial surface disturbance and "borrow" material would be better used, in <br /> any case, for topsoiling requirements. <br /> Necessary grading can 1:e accomplished by use of a bulldozer or excavator to <br /> round off the crest of the cut, using that material to fill in at the base, and <br /> otherwise grading the slope to the desired contour. <br /> The route followed by tho overland conveyor from the tunnel portal to the raw <br /> coal storage area could, similany, be contoured with use of a bulldozer or <br /> excavator, without hauling in material for backfill purposes. Also, this area can <br /> probably be successfully revegetated without bringing in topsoil. <br /> At the raw coal storage areas some coal material remains on the ground. <br /> Rather than haul it to the Sutey pile to cover it with soil material, we would <br /> c I,� propose to push it up against the cut of the hillside and bury it there, with soil <br />
