3),it is anticipated that minimal backfilling with overburden will occur during reclamation. <br /> Overburden present on site will be stored in the stockpile area and sold as fill. Mining to final <br /> slopes will reduce the need to stockpile backfill material and shorten the time that it will take to <br /> reclaim the mine. Details on topsoil and overburden quantities and material balance can be found <br /> in Table D-2 and Table E-2. <br /> 1.2 Mininiz Phases <br /> Mining will take place in a single phase and will entail the excavating of four pits starting at the <br /> south end of the permit area and progressing north. Once topsoil is stripped from the site,the <br /> deposit will be mined three to six feet deep using loaders and haul trucks. Final depth will be <br /> determined by the configuration of each of the four recreation fields. Upon final excavation of <br /> each pit,the pit will be immediately reclaimed and converted to an athletic field. Thus,no more <br /> than one pit will be mined at a time. The groundwater table will not be encountered during <br /> mining as the water table is currently at least 15 feet below the surface in the permit area. <br /> Mining will progress as shown on Map C-2. All mining will be to final 3H:1 V slopes on the <br /> perimeter. The active mining highwall will be mined to the final 3H:1 V mining slope. This <br /> means that at no point in the operations life will backfill be required for reclamation. The <br /> maximum disturbance at any time will be at the end of the mine life when the largest amount of <br /> rangeland requiring topsoil and revegetation is present. This worse-case scenario would be when <br /> one of the recreation fields is mined,but has not been reclaimed or converted to a recreation <br /> field. This worse-case scenario would also include the need to reclaim the soil storage area. This <br /> scenario will determine the bond calculation and is discussed in detail in Exhibit L. <br /> 1_3 Equipment <br /> Table D-1 shows the type of equipment that will be used for the operations of this site. Once <br /> operations are complete, all equipment will be removed from the site. <br /> Mystic Sol D-2 I1h WWI and As.o IWM M.1d <br /> November 2020 <br />
