1 <br />' EXHIBIT I -SOILS INFORMATION <br />Soils information was obtained from the USDA-Soil Conservation Service (SCS), Canon City, <br />Colorado, and from laboratory analyses of soil samples collected at the site (Figure 1; Table 1). <br />The SCS data are a compilation of old and recent soil mapping. Included are map unit <br />descriptions for the old 1B, 26-E, and 54-EF units. Also included are recent descriptions of <br />similar soils (see Attachment A, this section, for soil descriptions). The HS and NvH map units <br />correspond to the 1 B unit. The Quander component of the PF unit closely represents the <br />. dominant soils of the 26-E unit. The SI (Ivywild-Catamount complex) unit should be a very <br />good representation of the soils of the 54-EF unit. <br />'~ At present, the range in peat and muck thickness on the parcel has not been observed. The HS-- <br />Histosols and NvH--Histic Cryaquolls are two map units of small extent and current mapping <br />that may best tit the soil units in the Gillett Parcel. These consist of very poorly or poorly <br />drained soils. The Histosols have organic peat layers that are usually about 4 or more feet thick, <br />' and the Histic Cryaquolls have organic layers about 8 to 16 inches thick. <br />Soil properties and SCS criteria for rating soils as a reclamation material at the Gillett site are <br />' enclosed (Tables 2 and 3). These criteria particularly apply to material used as a final cover. <br />Salinity, sodium adsorption ratio (SAR), and toxic materials of any layer should not be limiting <br />to reclamation success. <br />The most problematic reclamation area will be soil unit 54-EF (Figure 1; Tables 2 and 3; <br />Attachment A). Soils of this unit will be coarse, infertile, and droughty after mixing. <br /> <br /> <br /> <br /> <br /> <br />' .~,~.k..., <br />_~N: 19 <br /> <br />
