6. It is unclear how the relation of mining Area 1 and Area 2 will interact. It is logical that <br /> overburden from Area I will be used as backfill for Area 2. The timing and interaction <br /> of these simultaneous operations is not discussed in enough detail. <br /> Please see the revised Exhibit D. <br /> 7. Several different setback distances from various features are listed on Map C-2. Will <br /> mining occur vertically up to the setback or at a 3H.- 1 V up to these setbacks. What <br /> setback distance will slopes transition from vertical to be knocked back down to a 3H.- <br /> I V to achieve the various setback distances? <br /> The setbacks shown on Map C-2 are the minimum setbacks from various structures, easements, <br /> and property lines for excavation. This means that the crest of any excavated slope will not be <br /> closer than these setbacks. <br /> The vertical mining highwall is limited to the midpoint of the final 31-1:1 V slope to ensure that <br /> when the final slope is installed by dozing down the vertical highwall,the permanent slope stays <br /> outside of any setbacks. <br /> 8. Provide additional information regarding the scale and scale house mentioned on page <br /> D-3. Will any sort offoundations be installed, what type of building, etc.? <br /> The truck scale and scale house will both be portable to allow ease of installation and removal. <br /> No foundations will be poured. <br /> 9. Does table D-2 include material handled in support of Area 2?Clarify if the volume <br /> described in D-2 is excess material after the completion of Area 2 backfill and topsoil. <br /> Describe the amount of topsoil and overburden handled per mining area. (PageD-4) <br /> Please see the revised Exhibit D. <br /> 10. It is unclear when mining of Area 2 specifically will take place. Table D-3 states mining <br /> progressing south to north but Area 2 involves mining east to west. <br /> Please see the revised Exhibit D. <br /> 11. Regarding the Disturbed area or size to be worked at any one time. The maximum <br /> disturbance as described appears to only take into account S acres at Area 1. Will Area <br /> 2 be completely reclaimed prior to Area I and limited to no more than S acres <br /> unreclaimed? Or if at least half of the reclamation is to take place by the end of <br /> completing Area 2 approximately 8 acres would require reclamation in addition to <br /> Area 1. <br /> The maximum portion of the disturbance areas in Area 1 and 2 that will require topsoil and <br /> revegetation will be 10 acres. Please see the revised Exhibit D. <br /> 12. Will any material be imported for backfill? <br /> See section 9 of the revised Exhibit D. <br /> 23 114 West Pit 3 <br /> October 2020 <br />
