Banks and Gesso, LLC <br />The slurry wall installed around the perimeter of Mine Area 1 will seal off the pit, <br />preventing further infiltration of groundwater into the mining area. During initial <br />excavation, dewatering quantities will be high. Once the mining area is pumped out, <br />continued dewatering will not be required. <br />The Applicant will obtain 101 shares of water from the Lupton Meadows Ditch Company, <br />which will deliver approximately 283 acre-ft of water for use in augmentation. The <br />existing irrigation well in the southeastern corner of the property will be used during <br />operations and be converted to commercial use prior to mining. These rights will <br />account for losses in the aggregate processing operations. A Temporary Substitute <br />Supply Plan (TSSP) and Gravel Well Permit will be obtained prior to any disturbance of <br />groundwater. <br />Operations Timetable <br />Mining and reclamation activities will occur concurrently throughout the life of the mine. <br />As areas are cleared, grubbed and stripped, mined slopes will receive backfill material to <br />establish the permanent design side slopes. Mining is estimated to be completed within <br />7 years from the date of start-up. Final reclamation of the mined slopes will be <br />completed within 1 year of the completion of mining. <br /> <br />Phase Duration <br />Mine Area Area to be Phase(s) to be <br /> ears Mined acres Reclaimed <br />1 6.7 1 61 1 <br />2 0.3 2 7 1& 2 <br />Phase 1 Mining Sequence <br />The Applicant will locate the aggregate processing plant, asphalt batch plant, concrete <br />batch plant, maintenance building and office facilities as shown on Exhibit C-3. A slurry <br />wall will be installed within the 25-ft setback around the perimeter so that the area can <br />be efficiently dewatered, and also so the site can serve as a water storage facility after <br />mining. Prior to placement of processing facilities, the area beneath the plant site will be <br />stripped of overburden. Stripped overburden will be stockpiled for later use in <br />Heit Sand and Gravel Mine 02044 <br />SW Meadow, LLC February 2003 <br />7 <br />
