Stormweler Mvnveemenl Plvn 01/04/98 <br />• A series of permanent berms will be constructed along the southern permit boundary to <br />reduce noise and impair visual examination of the project. These berms will be <br />constructed from rock and sand material not sold from the project. As the permanent <br />berms are completed, topsoil will be removed from the temporary topsoil stockpile and <br />placed in a 8-10" layer and be seeded. A table of anticipated topsoil volumes for each area <br />is included for review. The difference between the temporary topsoil stockpile and that <br />used for the permanent berms will be used to reclaim each future mine area. After gravel <br />area IA is mined, the top soil from Phase II will be used to reclaim gravel area IA and the <br />remaining permanent berms. Likewise, topsoil from Phase III will be used to reclaim <br />gravel area II when the latter azea is completely mined and Phase III area is started. <br />Direct haul of topsoil to final placement will be a priority to maintain the soil's integrity <br />and minimize haulage. <br />The temporary topsoil stockpile will vary in height and width so as to blend the stockpile <br />into the surrounding topography. Topsoil stockpiles will be graded to no more than 2.0:1 <br />to 2.5:1 slopes prior to temporary seed mixture planting to promote wind and water <br />resistance. The topsoil stockpile is oriented nearly perpendicular to the prevailing wind <br />(north-northeast) to decrease wind and water erosion potential. When portions of the <br />stockpile are removed for soil redistribution, removal will take place on the east or west <br />ends to limit disturbance. The topsoil stockpile will be marked with a sign to insure that <br />the stockpile is not inadvertently contaminated with other materials. <br />PERMANENT BERMS TOPSOIL USE <br />Estimated <br />Berm CuYd Topwil Cover Acres <br />CuYd <br />Temporary Top Soil Herm 113,615 N/A <br />4.39 <br />Permanent Berms <br />Southern Railroad Loop <br />33,022 2,611 2.05 <br />Western Wye <br /> 19,333 1,528 1.20 <br />Eastern Wye <br /> 8,533 843 0.66 <br />West of Western Wye <br /> 69,102 5,009 1.99 <br />SE Permit Corner <br /> 38,667 3,057 2.40 <br />Overburden Stormwater Berm <br /> 16.800 2 698 2.02 acres in disturbed road/RR/Pond area <br />Totals 185,458 excludes storm water berms <br /> 15,746 8.29 <br />• <br />Permanent Berms, Previously Mlned Land <br />Pape 17 <br />
