NEWMONT <br /> submit u revised specif iccrtion for DC'F to reflect the proposed change in grudcztion. <br /> b. 0 210 Underground Working Remediation. Section 2.3 of the f"LF?Phase 3 Design Report <br /> discusses how underground workings that may he encountered are to he treated, hilt no <br /> specification for this work is included in .4ppendix E. If underground workings tire <br /> encountered how is the contractor to know what specifications tyre to be followed:' The <br /> Division recommends the previousli, used underground workings remediation <br /> specifications 0 210: 03310 - Cemented Rockfill, 03320 - Concrete Plug, and 03330 - <br /> Flowable Fill be included in .4ppendix E. If not, and underground workings are <br /> encountered the Division nzav require a technical revision. <br /> Newmont Response: <br /> a. An updated Earthworks Specification has been included with the updated design report. <br /> b. The following technical specification have been added to Appendix E: 03310—Cemented Rockfill, <br /> 03320—Concrete Plug, and 03330—Flowable Fill <br /> The updated design is provided in Attachment 13. <br /> DBMS Comment(italics): <br /> 86. .4ppendi-c F - Slope Stabilia, Results. The following comments relate to the slope stability results <br /> provided in.4ppendix F of.4ppendix 1. <br /> a. Based on Drawing.410, Stage C Grading Plan, the SG0 4 grading appears to be (it a <br /> 1.5K-1 G'slope in excess of 150 feet in some places above the proposed edge of liner. .Vo <br /> stability, anulvsis of'this area is included The liner is considered an EPF and a critical <br /> structure. Please provide a stability analysis for the 150 plus foot high SGO&4 slope above <br /> the edge q f l iner. <br /> b. ,'neither Figure I or? in.4ppendix F.1 have a date or signature of the preparer us required <br /> by Rule 6.2.1(2). Figure ? has a large "DR4FT" .stump on it. Please resubmit Figures I <br /> and?with the required in formation and without a DR4FT stamp <br /> c. .-ill six ",Stability Graphics"figures in.4ppendix F.2 have a dotted reel line. Please explain <br /> what this line represents. <br /> Newmont Response: <br /> a. An additional stability section has been developed for the Squaw Gulch layback slope. <br /> b. A signature and date have been added to Figure I and 2 in Appendix F and the draft stamp has been <br /> removed. <br /> c. The red dotted line represents the geomembrane liner interface in the stability analysis. <br /> The stability analyses are included with the updated VLF2 Phase 3 design, provided in Attachment 13. <br /> APPENDIX 2 <br /> DBMS Comment(italics): <br />
