EARTHMOVING <br />6.4.4 Exhibit D — Mining Plan <br />MINING METHODS <br />All of the mining operation will be "dry" mined. Dewatering trenches will be dug <br />around the perimeter of each mining cell and dewatered to Boulder Creek. <br />Stripping and mining will incorporate conventional aggregate mining methods, <br />including use of scrapers to strip overburden, backhoes and scrapers to mine <br />sand and gravel, and haul trucks to move material onsite. This operation will <br />mine and reclaim concurrently wherever and whenever possible. The permit <br />area has been divided into mining cells. The general order of mining activities is <br />given below and will generally follow the numeric sequence assigned to the cells, <br />however unforeseen operational considerations may cause the order of mining to <br />change. <br />Stripping of overburden described below includes stripping of topsoil as well as <br />overburden soils. Topsoil shall be segregated and stockpiled separately from <br />overburden. <br />CeII 1 <br />Mining of CeII 1 has been completed. Following mining, the weathered shale <br />bedrock was excavated to increase the reservoir storage volume. Approximately <br />631,000 yd of excavated shale has been stockpiled in CeII 2. <br />CeII 2A <br />Mining has been completed in the western half of CeII 2A. <br />Overburden from the eastern half of CeII 2A will be stripped and stockpiled in the <br />western half. Mining of the east half of CeII 2A will proceed to the east. See <br />Exhibit C -2 Mine Plan, Sheet 2. <br />CeII 2B <br />Overburden from CeII 2B will be stripped and directly replaced in backfill areas of <br />Cell 2A. Mining will generally proceed from west to east. See Exhibit C -2 Mine <br />Plan, Sheet 2. <br />CeII 2C <br />Overburden from CeII 2C will be stripped from the western portion of the CeII <br />(long narrow strip of land) and directly replaced in the backfill areas of CeII 2B. <br />The overburden from the eastern portion of Cell 2C will then be stripped and <br />placed directly into the western portion (long narrow strip of land) backfill area. <br />Mining will generally proceed from south to north.
