6.4.5 Exhibit "E" : "Reclamation Plan <br />amendment If the .plan contemplates mining the material underneath the road, the <br />operator shall include the road as part of the affected area When and if the plan <br />proceeds to mine the material under, the road, the operator can submit a technical <br />revision to'the`permitrather:than an amendment to change the mining and reclamation <br />plan at that time. <br />2) Under Diversion and Impoundments, the operator states, "As the mining operation <br />nears completion, the southern end of the pit will be contoured to .drain feely into the <br />Rock Creek valley ". Please note, no affected drainage can be allowed to free drain into <br />unaffected drainage area, during the mining and reclamation activities without the <br />approved ` storm water permit from the Colorado Department of Health and <br />Environment. Once the site is released, the operator can allow drainage from the <br />released area into the natural channel. <br />3) Under material processing and associated facilities, the operator states, "material <br />processing will be re- located from the existing Fountain pit location to the amendment. <br />area. The processing facility potentially consisting of conveyers screens washers and <br />crushers, will be placed in the bottom of the amendment area mine pit as soon as <br />possible ". Are these items portable and already covered in the reclamation warranty <br />calculation for the site? Since the current warranty for the site did not have the <br />warranty calculation for removal of such items, the Division will need the dimension of <br />the conveyer system including the length and width of the belt. How is it going . to be <br />anchored in place, would it require concrete type footings? How many of these footings <br />are going to anchor the conveyer system. What are their dimensions? Please explain. <br />) Under the reclamation plan the operator states, "Since two . separate options are <br />included for mining; the reclamation plan will change slightly depending upon the <br />mining plan followed ". As explained in item # 1 of the mining plan, the Division cannot <br />approve two ;options. Please select one of the options for this amendment. <br />Under general overview of the reclamation plan the operator states, "The pit floors will <br />be blended in to the Rock Creek Valley and drainage ". Please refer to comment under <br />Exhibit `'D item #.2. <br />3) Under materials handling and grading the operator states, "The 3H:1V pit side slopes <br />will be graded to transition into relatively flat pit floors. Grading of the pit floors will <br />leave a subtle rolling topography rather than a completely flat bottom. Does the <br />operator; plan to leave in place some of the deposit or use over burden to create theses <br />subtle rolling topography? Please explain. <br />4) . Under top soiling and growth medium, the operator states, "the overburden will be <br />spread first as previously discussed. Initial material balance estimates suggest that <br />overburden material may not be sufficient for slope backfilling and pit bottom cover. At <br />most, no more than a couple of feet of overburden will be available to top dress the <br />final pit floor. The worst case scenario is that the pit side slopes will be created using a <br />cut and fill approach and the side slopes and pit bottom will be top dressed with a <br />
