V4 <br /> The Division continues to believe this plan would result in the greatest stability, and is <br /> the plan which should be implemented. Certainly this is the least expensive to <br /> implement. <br /> Downslopes Below Benches <br /> In the early days of the operation a good deal of coal waste material was dumped or <br /> carried over the side of these benches, where it remains deposited on long steep <br /> sideslopes. <br /> We have maintained that these were pre-law disturbances and we should not have to <br /> recfalm them. The Division disagrees. The present reclamation plan is silent as to <br /> whother, or what would be done for reclamation of these areas. We have indicated to <br /> the Division that we frankly don't know of an effective method for reclamation, and that <br /> the cost could well be prohibitive. <br /> There was some discussion of taking a hydromulch machine (which will probably be in <br /> use for vegetating other areas of the mine) to the top and bottom of one of these slopes <br /> and blowing on seed and some sort of mulch to see if some vegetation could be <br /> started. <br /> We had suggested constructing a series of catchment basins at the base of the slopes <br /> to catch sediment, intending this as an inexpensive alternative to attempting to <br /> vegetate these slopes. They do like the idea of catchment basins, but are still insistent <br /> that some effort be made to vegetate the downslopes themselves. <br /> Backfill/grading <br /> The current plan calls for trucking soil and other material to use as fill at various areas <br /> of the mine, including the hillside back of the preparation plant and the route of the <br /> overland conveyor.2 <br /> We suggested that these areas could be reclaimed more effectively by grading (using <br /> a bulldozer) rather than backfilling to achieve the desired final contour of the land. This <br /> would eliminate substantial ;rucking costs, and alleviate the problem of finding material <br /> to use for backfill. <br /> They Division agrees with this concept. <br /> In addition, the Division also agrees that coal material which remains on the ground in <br /> the raw coal stockpile areas, and the area of the storage silos could be pushed against <br /> 2 The bond calculates backfill costs as follows: <br /> Backfill Prep.
