deposit thins toward the south and is thicker toward the northern sloped eroded hillside areas that drop off the ridge top. Test pits excavated at the site (above the old pit and along upper gentler slopes 3 to 12 % slopes) have been described as having less than 8 inches of loan/topsoil covering the underlying aggregate. The aggregate material was described as being very coazse sandy gravel with > 50% rock materials. The rock is composed of mostly 2 to 10 inch sub-angular to sub-rounded cobbles andi rock fragments with some thin very coarse sand lamiae extending to the underlying bedrock in some pits to a depth >25 feet. The deposit is oriented in a triangular area from just above the "old pit" area south, up the slope to the southern fence line then east to a point where the large draw truncates the gravel deposit. The draw is located on the map at a point a little more than '/2 of the distance across site along the ridge to the east permit boundary. The soils in the area of the proposed operation area as mapped and described by the U.S.D.A. Soil Conservation Service consists of soils belonging to the following types (Maps and Non-Technical Soil Descriptions are attached to the soils exhibit section). The soil types are listed in the order of their possible aggregate potentials as indicated in typical site test pit descriptions and typical exposures from the previous mined and disturbed site areas. Permit area soil types are as follows: ^ Torriorthents-Torripsamments,l2 to 40% slopes ^ Tresano, sandy loam, 3 to 12% slopes ^ Rock River, sandy loam, 12 to 25% slopes ^ Ryan Park loamy sand complex, 3 to 15 ^ Youngston, loam well drained 0 to 3 % slopes There will be no mining to the east of the "cut-off' draw feature as the major aggregate deposit is all to the west. The east'/z of the site may provide some surplus topsoil (Ryan Park sandy loam, 170) for future reclamation from the northeast edge of the site between the dry drainages and the slope toe. The west edge of the site will also not be mined either. This area is also located between the dry drainage and the base of the slope area. The soils here (~'oungston loam, 223) may also provide some additional limited reclamation cover soils. Any areas disturbed by removing surplus reclamation soils will be inunediately tilled seeded and reclaimed as soon as possible. Any surplus topsoil will be stripped and stockpiled at convenient locations adjacent to the active mine areas for use in subsequent concurrent reclamation activities. If topsoil stockpiles are to be left for more than I growing season, they will be seeded with the USDA recommended seed mix via broadcast method.
