' tXHIBIT I SOILS INFORMATION Two sails predominate in the area, the Numa Clay loam and Potter and Stoneham gravelly looms. The Numa soil is at the western and northern boundaries of the existing pit (Photo I-1 ). ' The pit boundary also is that soil boundary between the Numa and Potter and Stoneham soils. The actual commodity being mined is the Potter and Stoneham although the Numa soils have competent gravels beneath the solum, actually the C horizon, and are being mined in other areas. The Potter and Stoneham gravelly looms are the dominant ' soils mapped in the area to be mined, however, field review indicated that the mapping unit is mis-mapped and the actual soils that predominate are of the stoneham soil series. The ' difference between the Potter and Stoneham is one of depth to lithic material. The Potter is described to 9 inches and is to have indurated caliche (petrocalcic horizon) at or about this ' depth. This soil was not found on the area to be mined. Photo's I-2, 3, and 4 depict the Stoneham soil profile and the gravelly (often sandy) C horizon. The Stoneham soils contain varying amounts of gravel throughout the profile, but the C horizon starts at about 14 to ' 20 inches beneath the surface thus leaving very little topsoil for stockpiling or reclamation. What topsoil there was on these soils appears to have been removed from the site or incorporated into the sand and gravel as "binder". The soils generally have 10 to 14 inches of topsoil that can be removed for reclamation purposes. This material is usually sandy or gravelly and is subject to wind erosion. The organic matter content is low and the water holding capacity is also low. Rehabilitation will be difficult due to the potential wind erosion problems and the low water holding capacity. Foc revege- tation purposes 6,000 pounds of manure per acre would provide necessary water holding ability and mulch to reduce the erosion hazard that comes with the lack of organic matter content. The manure will also have enough straw mulch incorporated in it to ' reduce or preclude wind erosion. I II "
