. <br /> SSR <br /> MINING <br /> The slopes of the VLFs will be re-contoured to an overall slope of approximately 2.5H:1V. Portions <br /> of the benches created during operations will be retained, as appropriate, for geotechnical and <br /> erosional stability. The topography shown on Drawing F-1 and the financial warranty calculations <br /> presented in Exhibit L have been developed based on an overall 2.5H:1 V slope criterion. <br /> Growth medium will be applied to a minimum depth of six inches over the regraded VLF surfaces <br /> and associated disturbances. After placement, the growth medium will be amended as needed, <br /> and seeded pursuant to the procedures described in Sections 2.3 and 2.4 above. <br /> Closure and reclamation processes at each VLF, including neutralization (approximately six <br /> years), physical reclamation (approximately two years), and monitoring (approximately two <br /> additional years), are scheduled to take up to ten years after final leaching of ore has been <br /> completed at each facility. <br /> 2.7.3 External Solution Storage Pond (ESP) <br /> • Reclamation of the External Solution Storage Pond (ESP) remains unchanged from that approved <br /> in MLE under Amendment 9 and MLE2 under Amendment 10. The ESP likely will be used to <br /> facilitate final rinsing of the VLFs. Solution contained in the ESP at the conclusion of rinsing will <br /> be spray evaporated or treated with H2O2 and applied to the VLF. Any sludge that may remain in <br /> the bottom of the ESP will be removed, tested, and appropriately disposed of, most likely by <br /> hauling to and placing on the VLF. The ESP liner will be folded into the bottom of the pond and <br /> the impoundment area filled with material. Facilities demolition debris may be placed in the pond <br /> bottom prior to filling with material. The filled ESP area will be graded, soil will be placed, and the <br /> area will be reclaimed. <br /> 2.7.4 Haul Roads <br /> Haul road reclamation will occur in the same manner as previously approved for haul roads in <br /> MLE under Amendment 9 and MLE2 under Amendment 10. At the conclusion of mining activities, <br /> haul roads designated for closure will be regraded to blend with the surrounding terrain. Existing <br /> haul road embankment fill material will be pulled onto the road surface, where possible and the <br /> remaining road surfaces will be ripped. Cut slopes will be reduced or filled with material, where <br /> appropriate, to achieve the desired configuration. As appropriate on a location-specific basis, <br /> culverts may be removed or retained, with proper drainage accommodated in the field.
