• nama.2t I <br /> The soil that has been stockpiled as well as the cuts were <br /> examined for any obvious signs of poor quality zones. Soil cuts as deep <br /> as 5 to 6 feet revealed no zones that showed even slight signs of <br /> excessive calcium carbonate or other compounds that might produce <br /> questionable quality. The color and texture of the existing stockpiled <br /> soils do vary from location to location but do not indicate that any of <br /> the materials are questionable. All these materials seem to be of <br /> similar quality and the variations are within acceptable ranges to <br /> call them the same type for reclamation purposes. <br /> Stockpiling methods used to date appear excellent in that <br /> the available soil is being stripped to a reasonable depth where texture <br /> and color begins to change rather rapidly. Although windrowing the <br /> soil on the lower areas presents some possibility that clay and <br /> overburden uphill from the soil could contaminate the soil, it appears <br /> that any contamination is rather minor and of little concern. Under <br /> the circumstances I can see little other method of operating the <br /> mine in an efficient manner than is being done at this time. The <br /> current methods of stockpiling topsoil seems to have more advantages <br /> than disadvantages in that the current methods limits disturbance <br /> of more land that is necessary, provides reasonably good protection <br /> for the soil, and places the soil where it can be replaced on the <br /> regraded areas with relative ease. <br />
