Appendix E <br /> 82. The AMEC FTSF Design Report appendices are provided herein with the exception of Appendix E <br /> Tailings Geochemistry which is superseded by the application Appendix B. Appendix I Surface <br /> Water Management was considered in development of Appendix N Jesik Surface Water <br /> Management. AMEC's Appendix G Seepage is replaced with GEM Services Appendix B. Other <br /> than the already incorporated narrative regarding omission of Windy Gulch, no additional <br /> irrelevant appendices are included and the mine assumptions and proposed operations are <br /> based on Dawson Mountain only. <br /> 83. AMEC Appendix F Technical Specifications and Construction Quality Assurance is included in <br /> Appendix E. <br /> 84. The FTSF underdrain system will discharge directly into the contact water pond. As shown in the <br /> Appendix N, FTSF stormwater diversion channels divert surface flow directly to the contact <br /> water pond. <br /> 85. Appendix G of the AMEC Report states the underground seepage is estimated to be 0.7 gpm. <br /> The drain diameter is 4 inches which has a carrying capacity of 70 gpm or 100 times more than <br /> the estimated flow. <br /> 86. The underdrain will extend to the edge of the FTSF. <br /> 87. The starter buttress will be constructed of waste rock generated during construction of the <br /> portal and initial slope into the target deposit. This material is granite. It is not tailings. <br /> 88. Gabion baskets will be used where the surface water structure is temporary; removed during <br /> final reclamation. Gabion baskets are replaced with grouted structures where the structure is <br /> required post-reclamation. <br /> 89. AMEC's Section 8.2 is superseded with Section 2.4.6.4. Tailings filter feed slurry will be supplied <br /> from a "filter feed tank 4020-TNK-009"with a nominal capacity of 59 m3 or 4 hours of <br /> operation. This surge capacity(in some cases up to 24 ours) is traditionally allowed for <br /> unplanned operational upsets that may occur upstream and/or downstream of this tank.Thus, if <br /> the tailings filter cake is too wet due to a filter related problem,then the mill personnel will <br /> have 2-4 hours minimum to fix it (a hole in the filter cloth, loss of filter vacuum, etc.)without <br /> interruptions to the rest of the operation. If the tailings moisture problem is not solved during <br /> this period,then the mill is shutdown until it is resolved. Contingency tailings storage is also <br /> available in Zone 2 of the FTSF. <br /> 90. Riprap gradation will follow CDOT Riprap Gradation Standard. <br /> 91. The FTSF performance assessment methods in AMEC's Section 10.4 will be formalized prior to <br /> commencement of construction of the FTSF. <br /> 92. AMEC's monitoring well locations considered and incorporated into the Bishop Brodgen <br /> monitoring well network presented in Exhibit G, Section 2.7.4. Section 2.7.4 supersedes AMEC's <br /> locations as Bishop Brodgen considered a larger geological area than AMEC. <br /> Appendix K <br /> Items 93-98: After meeting with the Division on site and virtually, Zephyr has come to accept that <br /> the existing monitoring well locations and analytical suite were geologically inadequate and <br /> analytically incomplete, respectively. Upon Division's approval of the monitoring well locations <br /> presented in Section 2.7.4, monitoring wells will be constructed and monitored in accordance with <br />
