Trapper Mine; TR115 <br />Page 3 <br /> <br />the TR115 submittal. In order to ensure that the East Flume Pond will have the adequate <br />capacity to contain and treat the run-off or inflow entering the pond, the East Flume <br />Pond design must include the additional inflow resulting from the 83.78 acres of run-off <br />from the deal diversion. Please submit a revised East Flume Pond design that <br />includes the additional inflow as a result of the Deacon/Jeffway Diversion SEDCAD <br />model or provide the Division with a justification that the current design is <br />adequate. <br /> <br /> <br />1.5. Trapper provided a design for two diversion ditches; the Deal diversion and <br />Deacon/Jeffway diversion. Trapper did not update the reclamation cost estimate to <br />account for the reclamation of this diversion. The enclosed cost estimate includes a <br />cost to reclaim the diversion ditches based on the design of the ditches supplied and <br />the M51 map. <br /> <br /> <br />2. The topsoil stripping areas shown in TR115 do not coincide with the areas presented in the 2015 <br />ARR (TR116) for proposed 2016 stripping areas. Please resolve this inconsistency with the most <br />accurate information. <br /> <br />Trapper Response: Following discussion with DRMS, TMI provided drafts of maps 10B and the 2105 <br />annual reclamation report map provided in TR 116. <br /> <br />DRMS Response: The Division accepts these drafts and requests Trapper provide those maps as part <br />of the response to this adequacy review. <br /> <br />3. The topsoil stripping and replacement plan shown on the TR115, M10B Sheet 3 map does not <br />appear to be consistent with the topsoil replacement that has occurred for 2014 and 2015, nor <br />what is projected to be replaced in 2016. Also the 2015 Annual Reclamation Report Map <br />depicts a proposed topsoil stripping parcel for 2016 that is within portions of the 2016 parcel <br />and portions of the proposed 2017 topsoil stripping parcel depicted on Map M10B. Please <br />review the topsoil stripping plan and replacement plan depicted on the proposed M10B map <br />and reconcile it with what has occurred to date and what Trapper plans in 2016 and 2017. <br /> <br />Trapper Response: see prior comments <br /> <br />DRMS Response: This item is being addressed under items 2 and 4. <br /> <br />4. Based on the item above, please review Table 3.1-3 on proposed revised page 3-13 and make <br />any necessary updates to the topsoil replacement balance for the permit term. <br />
