Banks and Gesso, LLC <br />stripped from new mining areas may be moved directly to previously mined areas as <br />they are concurrently reclaimed. <br />Overburden will be continuously rotating during operations. Initially, overburden will <br />stockpiled in the areas designated on Exhibit C. Once the deposit has been mined from <br />the stripped portion, overburden generated from future stripping operations wil! be <br />placed in prior mined areas to backfill the pit. Final grading of side slopes will achieve a <br />minimum of a 3H:1V slopes (except for basin areas at least 10 feet below planned water <br />levels at 2:1 ). Backfill with overburden will bring reclaimed areas adjacent to the <br />proposed water storage basins up to approximate pre-mining elevations. <br />If the direct placement option is not available due to operational constraints, the stripped <br />overburden will be stockpiled at the locations designated on Exhibit C. There will be no <br />permanent stockpiles on this site once reclamation is completed; all stockpiled <br />overburden will be used to implement the reclamation plan for the property. <br />Mining will begin once topsoil and overburden have been removed from that phase area. <br />Mined slopes will typically be near-vertical, then concurrently reclaimed to a stable <br />configuration. As soon as mining limits have been reached in one phase area, <br />reclamation of the pit edges within that phase area will begin. As described below, <br />smaller mining cells may also be defined in the field to expedite concurrent reclamation. <br />This will allow for concurrent backfilling of the pit perimeter with previously stripped <br />overburden and/or material stripped from the next phase area to be mined. <br />Smaller mining cells, of a size to be determined in the field, up to 30 acres (the <br />maximum area of groundwater exposure), may be implemented to systematically stage <br />mining across the site. In the vicinity of the processing area, cells of approximately 5 <br />acres may be produced for process water settling and silt deposition, possibly by <br />creating earthen berms or by mining to temporary containment slopes. <br />The entire site will be graded to direct stormwater runoff towards interior ditches and <br />dewatering systems. A CDPS permit will be obtained from the Colorado Department of <br />Public Health and Environment (CDPHE) prior to discharge of groundwater. <br />Sundance Sand and Gravel Resource 06015 <br />Lafarge West, Inc. 8 September 2006 <br />
