5. Water Information. liig_bts and Augmentation <br />Since the mine will not encounter any water in the mining operation, there will be no need for water <br />rights or augmentation for this operation. Water for dust control and materials washing will be <br />supplied by irrigation wastewater on the property. <br />6. Drainage Facilities <br />The overall design of the drainage facilities is to contain the runoff from all disturbed areas for the <br />100 year - 24 hour storm. This will be done through the use o£ <br />a) Berms (8 ft height) to contain water that could drain offsite on the north, west, and south <br />boundazies of mining, and a berm on the northern edge of the old Metcalf Pit boundaries of the <br />mme. <br />b) A natural berm left on the eastern side of the mining area <br />The gravels which occur on-site aze very porous and in the event of water entering the pit, the water <br />will be allowed to settle through the gravels and will follow the natural path that the irrigation water <br />travels, which is along the dip of the shale which underlies the deposit. <br />7. Mining Timetable <br />The following timetables are the best estimate of the sequence of operations for the life of the mine <br />after August 2004 and are based on selling 400,000 tons of total product per yeaz. This production <br />is an estimate. Due to market conditions and other factors, the mining production may be different <br />than this estimate. Reclamation is included in this timetable since reclamation will take place <br />immediately after the mining of each phase. <br />As described in the general mining plan, Stages A and B will be mined concurrently. As seen in the <br />tables below Stages A and B will terminate at roughly the same point of time, which will be <br />Haldorson Sand and Gravel Mine 14 <br />
