SOILS INfORMATIO~i • there is a more loamy material and would be classified as a Kim loam. Once again variations in soil type at a much finer scale than the S.C.S. uses occur over short distances. The northeastern corner of the site is occupied by a large area of Ustic Torrifluvents and Kim loam with small amounts of the ManzanoLa and Heldt clays. Much of the area occupied by these soils is outside the permit area, but is on property under the ownership of the permit applicant. In a few of the deeper and larger valleys on the south end of the property ~J • the Pierre Shale outcrops directly on the surface. This shale or mudstotie formation rapidly weathers into a heavy, sticky clay which does not support much vegetation. In the bottoms of some of the washes, the formation directly outcrops in a rock form. These areas would not be included in a soil survey, but for purposes of designing a reclamation plan must be noted. The shale appears to weather into either the Manzanola or Heldt clay soil, but where coarse materials are available can also develop into a rich Kim loam or the Ustic Torrifluvents. Because the shale is under the gravels, these areas should not be directly affected by extraction activities, but may be used for minor support facilities such as roads to and from mining areas. SOIL SALVAGE. ~dP REVELATION: Within the area to be mined, the soils which will need to be stripped are the Schamber, the Razor, and a small amount of the Stoneham. Salvage depths on these soils are indicated on their respective diagrams. The depth of salvage ranges from 10" to 12". Of course, salvage could go much deeper on these soils, but this depth is considered to be the maximum depth for good quality topsoil which can be used as a growth medium. Soils below this depth become increasingly adverse in their characteristics and page 6 of 7 Exhibit I
