The recommended sail salvage thickness is based solely on the depth to sandstone bedrock. <br />The mean in situ suitable soil thickness for 30 Yinevada profiles is 30 inches (Addendum • <br />8, Tab 9). <br />The 33C, 53D, and 33E map units consist of 70 percent Yinevada with 10 percent splitro 10 <br />percent Coutis, 5 percent Foidel variant and 5 percent Roust inclusions (Addendum :i, 'ab <br />9). A 2.3-foot mean salvage thieknesa was used for Nap Units 53C, 53D, and 53E to <br />calculate recoverable soil volumes Meted in Table 1 and Exhibit 9-). This soil salvage <br />thickness figure accounts for inclusions and soil loss during salvage due to brush <br />elearinp. <br />53F-Yinevada Loam. This map unit is located on the very steep bedrock controlled <br />sidelopes end swales. No recoverable soil is available from this map unit due to very <br />steep slopes (Addendum 8, Tab 9). <br />66D, 66E-Foidel Loam. The Foidel loam soil is located on strongly sloping to steep <br />mountain sideslopes and cwales. The soil profile is deep and well developed with a thick, <br />dark colored surface horizon end subsoil clay accumulation. Adjacent soils have higher <br />subsoil clay contents (ROUIt) or lack subsoil clay accumulation (Splitro end Yinevada). • <br />The recommended soil selvage thickness is based solely on the thickness of the surface <br />mollic epi pedon and underlying transitional horizons since subsurface horizons have <br />unsuitable consistency characteristics. The mean in situ suitable soil thickness for 5 <br />profiles is 40 inches (Addendum 8, Tab 9). <br />The bbD and bbE map units consist of 80 pertent Foidel with 5 percent each of CouCis, <br />Rout t, Yinevada, and Splitro inclusions (Addendum 3, Tab 9). A 3.0-foot mean salvage <br />thickness was used for Map Units bbD and 66E to calculate recoverable soil volumes listed <br />in Table 1 and Exhibit 9-1. this soil salvage thickness figure accounts for inclusions <br />and soil loss during salvage due to brush clearing. <br />bbF-Foidel Loam. This map unit is located on the very steep mountain sideslopes and <br />swales. No recoverable soil is available from this map unit due to very steep ;:lopes <br />(Addendum B, Tab 9). <br />103-UStorthents-Cryoborolls Complex. This map unit is located on very steep mountain • <br />16 <br />
