May Day and Idaho Mine Complex 112 (d) Permit Application <br />within a year will be appropriately graded to slope, or decompacted by ripping if final grade cannot be <br />achieved until final reclamation, and revegetated. Rock storage areas that are complete and will not re- <br />ceive additional run of mine rock will be graded as appropriate and revegetated. <br />Development of the augmentation pond at the Idaho Operational Area will include interim reclamation of <br />the slopes which will be graded as specified in the Geotechnical Stability exhibit (Exhibit 6.5) and interim <br />revegetation of these slopes. <br />CDPHE Mandated Stream Restoration of Little Deadwood Gulch <br />Mine rock material within Little Deadwood Gulch at May Day No. 2 and Chief Operational Areas will be <br />removed per Colorado Department of Public Health and Environment ( CDPHE) requirements as detailed <br />in the Geotechnical Stability exhibit (Exhibit 6.5). Final grading will blend with the surrounding land- <br />scape and disturbed areas will be revegetated as defined in Section 6.4.5(2)(d) and (f) below. <br />Tailings Storage <br />The storage of mill tailings will be undertaken in the May Day No. 1 underground workings in accor- <br />dance with the Environmental Protection Plan (Exhibit T, Designated Mining Operation). <br />Reclamation Tyne 2: Exploration Reclamation <br />Exploration roads and drill pads will be developed in a sequential order, with only one in development at <br />any given time. During development of these components, vegetative material removed from the explora- <br />tion road corridor and drill pad areas will be moved to the May Day No. 2 portal rock storage /staging <br />area, shipped offsite to an approved landfill, burned or used as mulch. Upon abandonment, all solid waste <br />debris from the formerly active exploration drill pad will be disposed of off -site. The pad site will then be <br />ripped to decompact the surface and revegetated. The exploration roads will be permanent and not re- <br />quire reclamation. <br />Reclamation Type 3: Final Closure and Reclamation <br />Wildcat will remove, recycle or dispose of liquids and wood from the site in accordance with applicable <br />waste management regulations. To the extent possible, steel sets, process equipment, generators, wire etc <br />will be salvaged. Materials not considered toxic or hazard- producing will be dismantled, and cut for dis- <br />posal underground. The solid waste will be placed in the mine rock storage stope. <br />Portals will be appropriately backfilled with crushed rock, sloped and closed in accordance with DRMS <br />requirements. The portals will be barricaded or collapsed. Mine rock will be backfilled on benches such <br />that the mine portal is buried under 5 feet or more of cover and graded with slopes equal to or less than <br />1.5(H):1(V) (Figure E -1). <br />With the exception of the bench out slopes and the portal face (1.5H to 1V), slopes will be reclaimed to <br />2(H):1 (V) or to slopes no steeper than the existing topography where the natural slopes are estimated to <br />be 1(H) to 1(V). Where possible, slopes will be graded to approximate original contour. The post mine <br />topography will blend in with the existing topography. See Figure F -1 May Day No. 1, Figure F -2 May <br />Day No. 1 Rock Disposal Area extension, Figure F -3 May Day No. 2, Figure F -4 Idaho, and Figure F -5 <br />for the Lamb and Chief reclamation plan for the affected mine lands. <br />Within the augmentation pond at the Idaho Operational Area prior to reclamation, fresh water will be dis- <br />charged to an adjacent drainage channel or spray irrigated on the ground in accordance with CDPHE dis- <br />May Day Idaho Mine Complex 112(d) Permit Application <br />September 21, 2010 <br />
