Transit Mix Concrete Co. <br /> slopes will be graded to 3H:1 V or flatter, retopsoiled, and then revegetated. These areas <br /> are shown with the green hatching on the phase maps. <br /> 24) In Figure C-8, there is a gap shown between the reclamation area across the northern slope <br /> of the F2 backfill area and the western edge of the plant area. However, in Figures C-6 and <br /> C-7, this gap area is shown as being reclaimed. Is this an error? Please explain or correct <br /> any errors on the appropriate figure(s). <br /> Response: The eastern extent of the F2 stockpile has been revised to be consistent for all <br /> the phases of the mining operation. <br /> 25) In Figure C-7, the southwestern pit crest is adjacent to the F1 fines/overburden stockpile <br /> area, and no access road is shown connecting the pit to this stockpile area (as shown in <br /> Figures C-4 through C-6). Please clarify how the operation will continue to access the F 1 <br /> fines/overburden stockpile area and TS2 topsoil stockpile during this mining phase. <br /> Response: The road connecting the F 1 benches to the plant area has been revised so that <br /> the fines and topsoil stockpiles can be accessed throughout the life of the quarry. Figure C- <br /> 7 has been updated to show ramp access to F1 fines/overburden stockpile from the adjacent <br /> pit area. This ramp will allow dozers access to F1; the dozers will create access ramps on <br /> the F 1 fines/overburden stockpile as necessary to provide access to TS2 stockpile. <br /> 26) In Figures C-6 through C-8, the F2 backfill area is shown to be expanded southward during <br /> these mining phases (III-IV). Please explain how the operation intends to construct and <br /> continue to expand this backfill area, particularly with regard to access. How will the <br /> operation minimize disturbance of the previously reclaimed northern and eastern portions <br /> of the F2 backfill area as the backfill pile is extended to the south? <br /> Response: The backfill area will continue to expand southward as depicted in the figures. <br /> Access will be along the southwestern side of 172; ramps will be constructed using dozers <br /> and will progress southward as the stockpile expands. <br /> The F2 stockpile material will be end dumped or placed in lifts as the stockpile expands <br /> southwards. No new material will be placed on the north-facing slopes that have been <br /> reclaimed, and the northern and eastern portions of the F2 backfill area will not be affected <br /> by the expansion of the F2 backfill area. Berms at the crest of the stockpile will prevent <br /> disturbance to the reclamation areas. Dozers working on the backfill area will have maps <br /> (GPS) that provide areas where regrading and dump expansion are taking place. <br /> Additionally, areas that have been or are in the process of being reclaimed will be surveyed <br /> and staked. The Exhibit C figures have been updated to include an access road to the top of <br /> the F2 fines stockpile. <br /> 27) In Figure C-9, a portion of the reclamation area extends southeastward from the <br /> northeastern edge of the pit area down to Little Turkey Creek. Please provide clarification <br /> on why this area is to be reclaimed, and whether any structures or features will be present <br /> in this area during operational phases. Please confirm that any surface disturbance in this <br /> area will be kept within the proposed affected land boundary. <br /> Hitch Rack Ranch Quarry(M-2017-049) <br /> Response to Comments—March 9,2018 <br />
