Table 1. Factors of Safety for Slope Stability <br /> GALENA Lowest Condition <br /> Analysis Factor of <br /> Safety <br /> 2 1.38 Static model,worst case FoS <br /> 3 1.22 Seismic model,iterated from static minimum FoS <br /> 1 . Conclusion <br /> The Final Reclaimed slopes at Siskin Green Pit will be stable as designed. The difference <br /> between the CDRMS minimum FOS (1.5) for critical structures and the worst case modeled <br /> FOS (1.38) in this analysis is negligible. No structures exist downhill of the slope in question that <br /> would be at risk from slope failure. Given the lack of structures to be impacted, the non-critical <br /> standard is applicable, which both the static (1.38) and seismic (1.22) scenarios pass. In both <br /> scenarios the Final Reclaimed slopes at Siskin Green Pit will be stable. <br /> The slope stability analysis in this permit has been prepared according to appropriate <br /> engineering standards and practices. <br /> O�p,DOLL/� 'IN, <br /> ic&t 471'5i 'l: <br /> ess/ONALE�G-,_ <br /> Ben Langenfeld, P.E. <br /> P.E.# 0047151 <br /> Siskin 3 fix,,id. ` \sso fates <br /> August 2023 <br />
