If floodwaters reach as high as the stockpiles, the piles will not block the flood flows. The stockpiles in the northeast "finger ", which is not mined, can be in a round pile as flood waters are not expected here. If any, stockpiles along the eastern setback will have breaks between stockpiles equal to their face length. Floodwaters can thus flow around these stockpiles and proceed down River. Topsoil stockpiles will not be relocated. The overburden and topsoil material will be backfilled by scraper and dozers, whose tread marks will produce a rough surface on each layer and bind the next soil layer in. This roughness will be about three to six inches deep and will impede runoff across the surface. The pockets of moisture created by the roughness will increase grass and regenerating tree opportunity. 10. Revegetation The topsoil and overburden stockpiles will be broadcast seeded with the following mixture. In final reclamation, all affected lands will be drilled seeded with the following mixture. The seeded area will be mulched with two tons of weed free straw by discing in. The operator will consult with the local Natural Resource Conservation District to determine if fertilizer is recommended.
