Since the northwest corner of the property will be reclaimed as natural <br />pasture (prior to any commercial development), topsoil will be stockpiled for final <br />reclamation of the surface above water levels on this and other reclaimed areas. <br />Water Diversions and Imaoundments -Rule 6.4.4 lcl <br />Aggregate processing water at the GreenlCroissant Property Sand and Gravel <br />Mine will be separate from the dewatering and stormwater systems. Cells 1 and <br />2 have special functions relating to processing water. Following initial mining, <br />Cell 1 will be used as a water supply pond. In turn, Cell 2 will receive process <br />water in its western half (separated by a temporary dike, see Exhibit C-3). Silt <br />and fines will settle in the delineated section of Cell 2 for the life of the mine. The <br />silt ponds at the western area of the property will be maintained below existing <br />grades, so that any precipitation will be retained in this area. Moreover, some <br />de-watering discharges will be diverted back to the processing water system by <br />way of Cell 1. <br />Grading and shallow ditches on-site will direct stormwater from all areas of <br />surface disturbance into the mine property dewatering systems. Furthermore, in <br />Mining Cells 1 and 2, after the water is clarified and the sediments collected, <br />process water will be discharged into on-site ditches, or a pipe (if required by the <br />Division of Minerals and Geology), along the northern boundary and join flows <br />toward the Big Thompsori River. A Colorado Discharge Permit System (CDPS) <br />permit will be obtained for the discharge water associated with dewatering <br />operations. Tailwater ditches along the eastern property line will be relocated to <br />direct their flows to the river, in accordance with this plan. <br />Until slope backfill begins, dewatering quantities will increase as the initial <br />excavation enlarges and approaches the mining limits of Cells 1 and 2. Once <br />slope backfill begins in the later half of Cell 2, the quantities of groundwater <br />pumped will then remain stable. Since concurrent backfilling of the perimeter will <br />occur throughout Phase 2 and 3 mining, de-watering quantities are uniform and <br />GreeNCroissant Property Sand and Gravel Mine.CDMG.112 Permit 20023 <br />Loveland Ready Mix Concrete, Inc. $ March 2001 <br />
