Transit Mix Concrete Co. <br /> Division agrees this configuration can be an excellent method for protecting reclaimed <br /> slopes from erosion, promoting revegetation, and creating wildlife habitat. Please indicate <br /> on a figure in Exhibit F the approximate area(s) where this slope configuration will occur. <br /> Please provide an estimated acreage for which this process will be implemented. Will this <br /> process be implemented after subsoil and topsoil has been placed? Additionally, please be <br /> sure costs for creating these features are included in Exhibit L. The Division understands <br /> the process will be random, and therefore, values given in the bond estimate will be <br /> approximate. <br /> Response: The gouges will be placed on sloped portions of the fines stockpiles, and the <br /> gouges will be excavated into the subsoil prior to placing topsoil. Highwall slopes and <br /> benches will not contain these features. The gouges will be placed on approximately 99.5 <br /> acres for reclamation and approximately 28.6 acres for the Phase 3 reclamation cost <br /> estimate in Exhibit L. The costs for excavating the gouges have been included in the <br /> Exhibit L calculations. The gouging locations are shown on the maps in Exhibit F and L. <br /> 55) Please provide more details in Exhibit E regarding the drainage channels to be constructed <br /> across the quarry area and adjacent to the F1 stockpile for final reclamation. Please provide <br /> their approximate dimensions, slopes, the type of material they will be constructed in (i.e., <br /> backfill fines/overburden, granitic bedrock), and whether any additional materials will be <br /> required in their construction (i.e., rip rap). Please provide cross-sections of the proposed <br /> channels for each significant alteration in grade, profiles of the channels, and conceptual <br /> drawings for the proposed discharge areas. <br /> Response: A discussion of the drainage channel across the quarry area has been included <br /> in Exhibits E and G. Also, cross-sections and profiles showing the channel alignments and <br /> structure are included as Figures C-9d and 9e. <br /> 56) On page E-9, the Applicant states riparian reclamation areas are shown on Figures F-1 and <br /> F-2. The riparian areas across the pit and at the Little Turkey Creek crossing are shown on <br /> these figures. However, the drainage adjacent to the F1 stockpile area is not shown on <br /> either of these figures. Please show the location of this riparian area on Figures F-1 and <br /> F-2. <br /> Response: Figures F-1 and F-2 have been revised to more clearly show the riparian <br /> corridors across the quarry area and adjacent to fines stockpile F1. <br /> 57) On page E-9, the Applicant lists additional plant species to supplement the Mountain <br /> Shrubland mixture of Mountain Mahogany and Gambel Oak. The Applicant indicates <br /> differences in the supplemental mixtures may be necessary for dry upland areas versus <br /> moist areas. Please clarify the two separate seed mixtures for Mountain Shrubland <br /> reclamation areas. Please display the seed mixtures in a list or table format, as was done <br /> with the Riparian Mixture and Grass Seed Mixture. Please provide a planting rate for all <br /> reclamation species. <br /> Hitch Rack Ranch Quarry(M-2017-049) <br /> Response to Comments—March 9,2018 <br />
