' The temporary stockpiling of topsoil will be .in narrow low <br /> berms for wind and water erosion protection. The location, shown <br /> on the Mining Plan Map, allows no disturbance by ongoing mining <br /> operations. <br /> ' Once stockpiled, the topsoil will be handled as little as <br /> possible, if at all , until replacement on the shoreline. <br /> ' replacement of topsoil will produce optimum tilth for seed <br /> application. Compaction will be adequate to provide stability on <br /> Slopes. <br /> ' The topsoil replacement will be done in an even manner to a <br /> 8-I inch depth. Fertilizer. mulch, or other soil amendments <br /> ' will be added in quantities determined necessary after analysis <br /> of composite soil samples. <br /> ' Reveoetation <br /> The shorelines and surrounding disturbed areas are to be <br /> ' revegetated as part of the reclamation plan. <br /> Drill seeding will take place in the late fall or early <br /> ' spring to ensure maximum advantage of soil moisture availability <br /> when germination occurs. <br /> The following seed mix, is proposed to ensure the greatest <br /> probability of success and is based on environmental and <br /> biological factors common to the site. The mix provides for a <br /> diverse and long-lasting vegetation cover. <br /> ' Species Lbs.
