Deep Cut LLC - 22 West Pit Page 13 <br /> Adequacy response 01 Permit # M-2017-032 <br /> more than 350 feet of shoreline requires reclamation on Exhibit C —mining plan maps for all mining <br /> phases. <br /> This was originally shown on Map Exhibit C-1 Mining Plan Map, but have been labeled <br /> as the Mining Face. On both versions of the new Mining Plan maps I labeled this length of <br /> shore line as Mining Face. On maps in both scenario's I show the working face measures <br /> 350 feet long. Note, that slope areas adjacent to the working face are sloped 3h:1v or less <br /> and if needed some areas are reclaimed. <br /> 31) Please specify the maximum amount of shoreline to require grading to 3H:1 V, and the maximum <br /> amount to require grading to 5H:IV. Please be sure the shoreline grading costs provided in the bond <br /> estimate are broken down accordingly. <br /> As noted in the response to question 12, 350 feet would need to be graded at any given <br /> time no mater what area is being mined. This would either be 350 ft of 3:1 cut/fill grading <br /> or 100 ft of 5:1 beach grading. The Exhibit L - Reclamation Cost Estimate prepared <br /> includes a cost to do the 3:1 cut/fill bank sloping as item #3 on the second page of that <br /> exhibit. <br /> 32) Please break the reclamation costs down into the major phases of reclamation as correlated with <br /> the mining phases. Because the applicant is proposing concurrent reclamation where limited <br /> reclamation is required at any time, the reclamation plan should be consistent with the mining <br /> phases, clarifying what reclamation will be completed at each phase. For each mining phase,the <br /> applicant should include details such as location(s) of topsoil to be used with estimated haul <br /> distances, amount of shoreline requiring grading (specifying slope gradient), and acreage(s) <br /> requiring grading, retopsoiling, and revegetation. <br /> Please See the second page of the Reclamation estimate (page 63). For example, in the <br /> submitted version of Exhibit L Task #2 Resoiling showed the use of a Cat 6T dozer, push <br /> distance less then 100 feet, moving 9615 initial + 1.15 swell factor. In the revised version I <br /> did not included a resoiling cost since there is no material to be used for a seed bed nor <br /> will grass be planted since the site will be reclaimed as an industrial area in the old Plant <br /> site area. Since this is not a phased operation then a worst case scenario is the most <br /> appropriate way to calculate a floating bond. <br /> 33) Please include costs for removing and disposing of any junk or old equipment stored on the site that <br /> will not be used by the operation. <br /> An estimate is included in Revised Reclamation Cost estimate for 6 loads of scrap <br /> removal. <br /> 34) Please include costs for ripping up the concrete along the northwestern portion of the small pond and <br /> pushing the concrete rubble into the pond (or hauling off site for disposal). <br /> This old washout concrete will not be removed as it is a pre law occurrence and if not <br /> redisturbed by mining it does not need to be reclaimed. <br /> 35) The bond estimate submitted on page 63 of the application does not provide enough information for the <br /> Division to calculate the required financial warranty for the proposed operation. Please provide the <br /> following details: <br />
