Ci <br /> The current plan for reclGimation of the benches calls for grading of fill at the <br /> outside perimeter of the bench to achieve a moderate slope, using the material <br /> thus excavated to construct a buttress along the toe of the out, then seeding the <br /> area which has been graded. <br /> George Wear says that the downslopes themselves have not been included 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 ro-clamation at other bench areas, below other <br /> downslopes_ <br /> Backfill/grading <br /> 'The current approved plan of the (MLRD) permit calls for backfill of material at <br /> the hillside behind the preparation 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 a <br /> waste of money, and would create a less stable hillside. Further, there are <br /> scheduling problems in that we would like to cover most of the Sutey pile, whit <br /> would be the source of washer refuse material, next year, and would like to star <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 tl-iis baukfili 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 Le 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, similarly, 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 /> propose to push it up against the cut of the hillside and bury it there, with soil <br /> 2 <br />
