Slope reclamation of the previous phases will be concurrent with mining. Overburden will be <br /> placed in the reclamation slope or stockpiled in the bottom of the pit next to the current <br /> reclamation phase. <br /> Stage 5—will consist of mining out Cell 6 and concurrently reclaiming Cell 5. Cell 6 contains <br /> four(4)approximately one(1)year phases. Cell 6 will be a slurry wall lined cell and will be dry <br /> mined. The southwest underdrain will be constructed during the construction of the Cell 6 <br /> slurry wall. Water will be rerouted from the southern end of the site by the underdrain and <br /> piped to the Infiltration Pond to mitigate the groundwater shadow affect north of the site. <br /> Topsoil from this stage will be segregate and stockpiled in the western portion of Cell <br /> 2(Siltation Pit)to be utilized in reclamation of the silt pond back to native grade. <br /> Slope reclamation of the previous phases will be concurrent with mining.Overburden will be <br /> placed in the reclamation slope or stockpiled in the bottom of the pit next to the current <br /> reclamation phase.Any overburden not used in slope reclamation will be placed in the unused <br /> portion of Cell 2(Siltation Pond). <br /> Stage 6—will consist of mining out Cell 7 and concurrently reclaiming Cell 6. Cell 7 contains <br /> four(2)approximately one(1)year phases. Cell 6 will be a slurry wall lined cell and will be dry <br /> mined. <br /> Topsoil from this stage will be segregate and stockpiled in the western portion of Cell <br /> 2(Siltation Pit)to be utilized in reclamation of the silt pond back to native grade. <br /> Slope reclamation of the previous phases will be concurrent with mining.Overburden will be <br /> placed in the reclamation slope or stockpiled in the bottom of the pit next to the current <br /> reclamation phase.Any overburden not used in slope reclamation will be placed in the unused <br /> portion of Cell 2(Siltation Pond). <br /> Stage 7—the final stage will begin with mining out the aggregate under the Asphalt Plant,the <br /> Concrete Batch Plant and the office area.The last portion to be mined out will be the <br /> Aggregate Plant. Stage 7 will take approximately two (2)years and will establish Cell 8. <br /> Topsoil from this stage will be segregate and stockpiled in the western portion of Cell <br /> 2(Siltation Pit)to be utilized in reclamation of the silt pond back to native grade. Once mining is <br /> complete at the site,the topsoil berm will be mined and used in any areas needing topsoil for <br /> reclamation. <br /> Slope reclamation of the previous phases will be concurrent with mining. Overburden will be <br /> placed in the reclamation slope or stockpiled in the bottom of the pit next to the current <br /> reclamation phase.Any overburden not used in slope reclamation will be placed in the unused <br /> portion of Cell 2(Siltation Pond). <br /> The operator will develop and comply with a Stormwater Management Plan and Spill, <br /> Prevention, Control and Countermeasures Plan. The operator will notify the Division of <br /> Reclamation and Mine Safety and in the event of a reportable spill. <br /> Processing: <br /> The material will be dry screened or not screened at all and transported offsite by truck. The <br /> processing area will be located on the south side of the site in Cell 8. <br /> Section 20-Gravel Mine—MLRB 112 Permit Amendment <br /> Exhibit D-3 <br />
