Table D-3. Mining Timetable <br /> Years Activity <br /> 1 Stripping of initial mining area and Soil Storage Area <br /> 1-10 Mining the four pits,beginning in the south and progressing north _ <br /> 1-1Q Reclaim pits to recreation fields as mining progresses south <br /> j 10-11 j Completion of mining and final reclamation. <br /> Over the life of the mine, a total of approximately 666,000 CY of material will be extracted at a <br /> rate of roughly 66,000 CY per year. This will result a mine life of approximately 11 years(10 <br /> years of mining,one year of reclamation completion), depending on market conditions. <br /> 6. Disturbance Area <br /> The largest disturbance at any one time for this mining operation will be at the end of mining of <br /> any one pit. The area requiring topsoil and vegetation at this stage of the operation will be <br /> roughly one pit in addition to the soil storage area, a total of 64.3 acres. This is less than the total <br /> affected area of 319.8 acres, which is shown on Map C-2. Concurrent reclamation practices <br /> prevent the creation of the maximum disturbance area by reclaiming the mined out pits as mining <br /> progresses. See Exhibit L for a detailed discussion of the reclamation costs and bond calculations <br /> that are based on this point in the nine's life. <br /> 7. Deposit and Underlying Stratum Geology <br /> A soil report was generated using the United States Department of Agriculture's Natural <br /> Resources Conservation Services' (NRCS)Web Soil Survey (WSS)' and is included with this <br /> permit application(Exhibit I Soil Report). The soil survey encompassed the approximate <br /> boundaries of the permit area. While five soil types were mapped,the Gunbarrel,Kerber,Mosca, <br /> San Luis, and Space City. All five are similar and are described in part as containing loamy sand <br /> or sandy loam. The Gunbarrel and the Mosca comprise 95%of the permit area and will be <br /> discussed in more detail. The Gunbarrel is a saline, loamy sand and comprises 61.7%of the <br /> mapped soil survey. The Mosca is a loamy sand and comprises 33.3%of the mapped soil survey. <br /> Both the Gunbarrel and the Mosca report depth to a restrictive feature and depth to water table of <br /> more than 80 inches. Because mining will only occur to a depth of 6 feet(72 inches)it is <br /> 1 htti)s://websoilsurve�sc.ey-ov.usda.goy/App/HomePa eg htm. <br /> Mystic Soil <br /> November 2020 D-5 c:.
