• & screening plant and/or washing plant where various sizes of product will be sorted and placed in <br />separate stockpiles. <br />Crushing and screening activities will take place as a part of the operation in the following sequence. <br />1. The crushing and screening operations will initially take place on the facilities pad to the south of <br />Phases 1-3. <br />2. Once Phase 1 is mined out and mining has begun in Phase 2, the crusher and screener will be <br />placed in Phase 1. This will be the location of the crusher and screener for the remainder of the <br />mine's life. <br />Gravel stockpiles will be next to the crusher and screener throughout the life of the pit. Since the <br />crusher and screener will never be placed in a mining phase containing a wetland footprint, and the <br />phases are all in excess of 9.5 acres, no gravel stockpile will be near or within any wetland footprint. <br />Dozers may also be used to move topsoil or gravel. There will be no blasting as part of this operation. <br />• Mining and screening/washing activities are expected to occur at intervals during the year. Mining will <br />proceed in general from east to west through the phases numerically. At any one time, there may be <br />portions of two mining phases active. No stockpiling will take place within Phases 5-7 to ensure that <br />the wetland footprints are unaffected. Also, the site manager will have a GPS unit with the delineated <br />wetlands loaded onto it. This will allow the site manager to continuously review the operation and <br />ensure that there is no material place in any wetland footprint. The overburden from Phase 1 will be <br />permanently stored in the staging area, as shown on Map C-2. Topsoil and overburden will be stored <br />in Phases 1-3 during mining. Overburden and excess topsoil from future phases will be used to backfill <br />selected locations within the pit to create a sinuous and pleasing lake edge and wetland shelf once the <br />area is reclaimed. See Map F for details of the final lake configuration. <br />Flood event run-off will be contained within the mining pit allowing the pit to serve as the sediment <br />detention structure. Due to wet conditions, the pit will need to be pumped. The pit dewatering ditches <br />will flow towards the pit low point in the northwest corner. From there it will be pump to a sediment <br />. sump on the buffer between the pit and the river. See Map C-2 for details. The in pit dewatering pump <br />White River City Pit, August 08 D-2
