The mining excavation areas will observe a minimal 30 foot setback from the levee, 200 <br />feet from the Atchison Topeka and Santa Fe Railroad lines, and 400 foot setback from <br />the Arkansas River. These areas could be utilized for farm lanes or fire access roads. <br />The farm roads used during the mining operation will be scarified and revegetated, <br />however, the roads are anticipated to access the lake system. These road areas will also <br />provide adequate access for planting crews, supervision, and inspection by the <br />appropriate agencies. <br />Reclelmed Weter Impoundment <br />In the final land use configuration consisting of a multi-cell lake system, water <br />impoundment will continue to be incidental and temporary. As pointed out in other <br />sections of this report, flood flows from the Arkansas River may infrequently discharge <br />into the lake system where flood water will be stored and consequently discharged to the <br />Arkansas River alluvial aquifer. This recharge is accomplished through infiltration of the <br />lake systems side banks and bottom area. Surface waters are intercepted by means of <br />drainage ditches in the area of the sate and are conveyed east along the Atchison Topeka <br />and Santa Fe Railroad south along existing irrigation ditches to their historic discharge <br />at the Arkansas River. <br />Flows from these irrigation ditches will possibly discharge into the lake system. <br />Essentially, since the lake system will be excavated rather than dammed, natural water <br />impoundment associated with this lake system is not the prime intention. The lake <br />system will have water surface moderated by the local water table. <br />Reclematlon Detelle <br />Beckfilllny <br />As mentioned earlier, 73% of the mined material consisting mainly of sand, will be <br />discharged back into the pit. A slurry pipeline will carry the sand from the dredge to the <br />shoreline. The slurry pipe is flexible and its discharge and will be moved both vertically <br />and horizontally to form the desired shapes of the final lakes and attain the 3:1 and 2:1 <br />sideslopes. The lakes shown on Exhibit F are schematic in nature and there final shapes <br />and locations will be similar. <br />E-5 <br />
