There is mention in the mining plan of overburden to be stripped before mining and reused after mining. Please show where such material will be stockpiled during mining. The last inadequacy noted about the map is that it contains no signature of the preparer, though one is required. Sheet hvo of hvo appears adequate except that it also contains no signature of the preparer. To correct this might require a resubmitted map. It would not require a resubmitted map if, instead, a short statement were provided by the Wrap preparer, with appropriate signature and date. (For pertinent map standards and requirements, please review Rules 6.2.1 and 6.43.) Exhibit D -Mining Plan The plan describes the affected area as 46.20 acres. That figure is questionable for at least three reasons: 1) There is an as-vet-undepicted road through Phase 7, much of which will be disturbed and presumably will have [o be realigned, possibly including portions outside the affected area envelope; 2) there is now a proposed undercrossing of the overhead powerlines between Phases I and 7, which will also require final reclamation; and 3) there is a short segment of access road in the permit boundap- but outside of and adjacent to Phases l and ~ which shows different post-grading topographic contours (as depicted on the reclamation map) indicating disturbance to reclaim. The amount of affected area is important because it affectes the bond amount. Please check these observations, include these areas in your descriptions of areas to be affected, and revise the affected area acreage if necessary. As mentioned above, there is a lack of information pertaining to the woody debris generated as part of site stripping. Please provide the information, such as location of storage, methods of handling and disposal, amounts expected, nature of materials, etc. You state that overburden is expected to be up to six feet thick, and will be retained onsite for use in reclamation shaping of the site. Please describe where it is to be stored in the phases, and how, if at all, it is to be protected during mining. There are several references to the stornnvater controls in the application, including the areal sizes of the several ponds and height of the perimeter berm. Please state whether any of these structures was evaluated for adequate capacity for certain storm events and for what size runoff contribution (watershed) area. Is the drainage from the sedimentation pond to the retention pond to be via a constructed spillway, possibly riprapped? It appears dtat haybales may be employed, but it is not clear if i[ is to be in a spillway or what the embankment's surface material will be. Will any upland diversions be employed'? It looks from the diagram as though an outlet pipe will be used on the retention pond, but several details are not clear: what is the diameter and length of the pipe, what is the height of the pipe from the (original) pond floor, what is the route of the outfall and is it to be riprapped? Will surface runoff from these structures be the primary planned method of emptying the impoundments, or is percolation to be the primary plaaned method? Please describe die stratum underlying the gravel deposit to be removed, and whether the floors of the various pond strnctures are to be situated on that material. Will any upland diversions be employed? These details affect the onsite and downstream surfaces, and will affect the bond amount. Please provide the information requested above to clarify these questions. You have stated that the final 3: I slopes will be created after excavation. These final slopes will be attained partly through backfilling the stockpiled overburden and probably b}' pushing down unmined material above the final highw-all. l presume that the equipment used for mining will include dozers and loaders, which will produce a highwall ofan average of 1:1.
