It will have full <br /> secondary containment. All equipment onsite will have onboard diesel tanks in full secondary <br /> containment. Full secondary containment has 110%of the volume of the tank that is in it. <br /> 2. General Mining Plan—Method of Mining <br /> Mining at the 23 1/4 West Pit will be conducted in a single phase. Mining will be from south to <br /> north in Area 1 and east to west in Area 2. Maps C-2, C-3, and C-4 showing the extents of <br /> mining, a snapshot of mining roughly halfway through the mine's life, and cross sections of the <br /> mining and reclamation plans. The total disturbed area will be 41.4 acres. Of that total, roughly <br /> 10 acres of disturbed ground requiring topsoiling and revegetation will be active at any given <br /> time. The total disturbed area is shown on Map C-2. Crushing and screening of excavated <br /> material will take place onsite. Crusher fines may be placed in the lake during final reclamation <br /> or sold offsite as fill.No asphalt or concrete will be manufactured onsite. A truck scale and scale <br /> house will be installed onsite.No permanent plants of offices will be built onsite. <br /> Explosives will not be used at this site. <br /> 2.1 Mining Buffers and Limitations <br /> Throughout the mine life the setbacks shown on Map C-2 will be maintained.No mining will <br /> take place within the floodway, which is far off to the southwest. All mining will be within the <br /> floodplain, but no permanent fill will take place in this area. Stormwater control berms and <br /> stockpiles will be present during mining, but removed during reclamation. Additionally, the <br /> excavation of topsoil and overburden from the site will create storage volume for storm and <br /> 23 114 West D-4 <br /> October 2020 --- <br />
