C-11 r1 <br /> exposure to prevailing winds. In the event significant wind-borne dispersion or precipitation-induced erosion <br /> become factors of concern with respect to the stockpile integrity,CSC will employ back-up stabilization measures, <br /> if warranted; such measures may include the use of silt fencing, sediment logs, etc. and potential deployment of a <br /> cover system(e.g.,weighted tarps) and/or other measures consistent with best management practices. <br /> LWsoil Stockpile 2(Man Feature"TS-2—Perimeter Berms"):TS-2 will be contained within, and be utilized as, a <br /> series of continuous perimeter berms to be constructed around the perimeter of the main mine pit and the fines <br /> recovery pit, respectively. The roughly triangular-shaped (cross-section) berms will have a nominal 3-ft. apex <br /> height,with sides at natural angle of repose,and the overall(totalized)length of berm(s)is anticipated to encompass <br /> some 2,000 linear ft. On this basis, it is estimated that approximately 1,600 yd3, or approximately 18%of thetotal <br /> "topsoil"salvage volume will be accommodated(temporarily stored)within the perimeter berm system. <br /> It is anticipated that the berm features will be routinely maintained during the short duration operational life of the <br /> Project, to include grading/re-shaping (as may be required), and application of water spray in conjunction with <br /> loadout loop road dust control measures. <br /> (c) THICKNESS OF OVERBURDEN OR WASTE ROCK <br /> With the exception of the "growth medium", discussed above in sub-section(b),no "overburden"or"waste rock" <br /> mining is anticipated. As indicated above, the topmost 12-inches of material (i.e., "growth medium") will be pre- <br /> stripped(salvaged) and stockpiled for utilization in final site reclamation activities. <br /> All underlying excavated material will be considered run-of-mine(ROM) material suitable for processing; and, as <br /> such,will be stockpiled(per the mine plan) for subsequent processing, or delivered direct to the process plant feed <br /> hopper for introduction into the wet process plant. Thus, there will be no mining of overburden or waste rock <br /> materials associated with the Keenesburg Project. <br />
