<br /> <br />`J <br />EXHIBIT D <br />move from west to east, such that the last material to be mined will be the closest to the <br />settling ponds constructed during the dewatering phase. Overburden will be stockpiled <br />on the perimeter or th~it bottom as necessary, although reclamation may begin while <br />mining is in process, minimizing the space that overburden materials will occupy in <br />stockpiles. Resource will be handled in a manner similar to Phase 1, eventually being <br />transported across the river to existing distribution yards on the south side. The resource <br />will be used for internal as well as public sale. <br />A summary of the project phasing is as follows: <br />Table D-1.

This material will be stockpiled for reclaim and seeded with <br />fast-growing mix to avoid soil erosion if the piles will not be moved for more than one <br />growing season. <br />The same equipment will extract and transport sand and gravel resource. <br />A primary crusher~may be located on the pit floor. A conveyor system or tandem-axle <br />trucks will transport material to the south side of the river onto an existing permit site <br />where secondary crushing, washing, screening and stockpiling (generically referred to as <br />processing) will occur. <br />Section 3 -Water Diversions and Impoundments <br />Waterer y be diverted from the settling ponds/dewatering operations for wash plant and <br />dust control operations. This will be accomplished by simple pumping techniques and <br />held in water trucks or tanks, using as needed. Runoff and wash water will be returned to <br />the river via the dewatering trench and settling pond, if needed. <br />It is I~kel that~os on-site water needs will betaken care of by the groundwater from <br />the dewatering trench. A substitute water plan is currently being prepared to address <br />replacement of consumptive use. This will be provided to the DMG prior to exposure of <br />groundwater on the site. <br />
