• <br />ContA• n CMLRB 11] Penmlt Applieatlon <br />Agile Stone System,, Inc. <br />This screening berm is a permanent structure which will not be reclamed as <br />it is already revegetated during initial operations. <br />26. At the pre-operation inspection, the Division learned that the location of sections <br />of the permit area rail line would be moved and other sections would be <br />eliminated. Make appropriate changes to the Mining Plan Map. <br />Any discussed railroad track locations have been made and appropriately <br />marked on the appropriate maps. <br />27. It was also learned during the pre-operation inspection that the plant area for <br />gravel will be lowered 4-5 feet or more. Discuss this new land configuration in <br />the mining plan; describe what will be done with the excavated material; show <br />both on the Mining Plan Map and provide any necessary changes to the <br />reclamation plan and map. <br />The plant area on the gravel bar will be lowered an average of about 8'. See <br />Mining Base Map. The material from the plant area will be topsoil or plant <br />feedstock. The topsoil will be placed on the temporary topsoil pile. The <br />gravel will be placed on gravel area B after its topsoil has been removed. <br />28. The Division also learned during the pre-operation inspection that natural land <br />will be left as a barrier between Tallahassee Creek and the gravel extraction areas <br />A and B. Provide the dimensions of this barrier, and your plans for use of filter <br />fabric on the pit side and coarse rock on the creek side. Show this barrier (berm) <br />on the Mining Plan Map and provide a thorough discussion in the reclamation <br />plan. <br />The barrier between the Tallahassee Creek and the gravel extraction areas is <br />referred to as the Buffer. It will be 100' wide with roadway and appropriate <br />drainage swales/ditches. It is thoroughly delineated on all maps and <br />thoroughly discussed in exhibits D, E and I. No filter fabrics are planned to- <br />be used. <br />29. It was also learned during the pre-operation inspection that the gravel pit A and B <br />may receive runoff and process water from the plant area. Provide a discussion of <br />how this water will be controlled to prevent pollution of surface and ground <br />water. <br />See ezhibits D, E and G. Field percolation tests have demonstrated that <br />storm water events will be removed at the rate 1.5"/minute yet the 100 storm <br />11 <br />
