Water from the sump will discharge to two ponds, each approximately 170 x 85 x 8 feet, within an azea of <br />approximately 300 x 250 feet. The design for the treatment ponds is presented in Exhibit 8C(1), EMD Treatment <br />Pond Design. Approximately 5,550 cy of topsoil will be salvaged and stockpiled adjacent to this pond area. As <br />shown in Figure 1, Exhibit 8C(1), an access road (loop) will be constructed to the treatment ponds. Approximately <br />• 740 cy of topsoil will be salvaged from the short segments of road leading to the ponds. The topsoil will be <br />windrowed to the side of the road and seeded with the topsoil stockpile stabilization seed mixture. The topsoil <br />stockpiles will be stabilized with the topsoil stockpile stabilization seed mixture. <br />Prior to discharging into the ponds, the discharge water will be treated using the same methods used at the Fish <br />Creek Dewatering site to aid in settling of suspended and dissolved materials. A piping manifold or fittings and <br />valves will allow selective discharge to the ponds to maximize their use and efficiency. An interior line between <br />the two ponds will allow for flow between the ponds. A 15-foot wide road will encircle the ponds to provide for <br />maintenance and repairs. An 8-inch discharge line buried approximately 4 feet deep will carry the discharge to <br />Foidel Creek. A flow measuring device will be used to obtain the appropriate flow measurements. A 10 x 15 x 30 <br />foot building will house the treatment system and control panels for the dewatering pump. The building will be <br />constructed on a 10 x 3' x 0.5 foot concrete pad, as shown on Maps 17 and 18. <br />Sediment control for the site will consist of seeding and (if necessary) mulching the topsoil stockpiles and cut and <br />fill slopes, and use of an adjacent established vegetative filter. The SAE demonstration for this area is presented in <br />Exhibit 8C, EMD Dewatering Treatment Facility. <br />• <br /> <br />MR07-216 2.05-78 05/28/07 <br />
