Angie Pit Adequacy Response Letter Page 2 17 Generally, material becomes compacted during the backfillir:g process, as does the pit floor. Tl:e reclamation plan will need to inchrded provisions jor- ripping compacted areas prior [o placement of topsoil. Additionally, with the smidstone layer underneath the gravel identified as an aquifer, the reclamation plant must ensure that a minimum of hvo feet of cover remains over the sandstone for finnl reclamation. The operator commits to ripping any compacted areas of the pit and, if the sandstone layer is exposed, the operator commits to placing 2 feet of cover material over the sandstone before final reclamation. If the sandstone layer is not exposed, due to the presence of groundwater, the operator will leave a minimum of 2 feet of material over the ground water horizon and it will remain in place a[ final reclamation. 18 Does the maximum highwall length fgures, provided for each phase, include the "wing" areas adjacent to the advancing face, that have not yet been backfrlled? If not, please indicate how far behind the advancing face the highwall backfilling process will take place. The operator commits [o keeping the slope reduction of the side slopes [o within 300 feet of the advancing face. If the project does not provide sufficient material to maintain this slope reduction interval by filling methods, the operator will offset the projection for vertical pit excavation and construct the side slopes by cut and fill methods, taking care no[ [o encroach upon the disturbance boundary. 27 It appears that the fences and access roads either partially w• wholly owned by Ms. Allen are within 200 feet of tl:e proposed affected area boundary in several places.
