84 <br />RFL064~gS]DID TbPSOIL SALVAGE DEP'T'HS <br />• <br />9904-PERSAYO. Salvage depths for the east pit area soils (Sec- <br />tion 31) will be identical to those recort-nP~ded by Fly and <br />Associates for the west pit area soils in Section 25 (see Tab 9, <br />Table 2; Tab 9, Attachment 1, Section II; and Stripping Isopach <br />arr] Topsoil Stockpile P7ap, Exhibit 9-2). Approximately four (4) <br />inches of fair quality "A" horizon surface soil will be salvaged <br />with t~ (2) inches of lv..er quality "C" horizon substratum mate- <br />rial. The major limitations for the "A" horizon are the fine <br />textures (sandy C:IOy loam to clay loam). The high coarse fragment <br />content in the "C" horizon (this soil has a shallow paralithic <br />contact with interbedded sandstones arri shales) reduces its top- <br />soil, quality. <br />18-TORRIORTHENT-ROCK COMPLEX. Surface soil accwmilations are very <br />shallow to abscent on these steep to very steep south facing side- <br />slopes. The topsoil suitability rating is poor or unsuitable due <br />• to severe limitations inclu3ing high coarse fragment content, shal- <br />low soil depth, very steep slope, fine texture, and hard consistence. <br />This profile was not sampled because there will be no additional <br />mine disturbance associated with this map unit. However, if dis- <br />turbances were to occur, no topsoil salvage is recatmended. <br />CQ~CLUSION <br />Similar types of mining disturbance will occur in Section 31, the <br />East Pit Area, as do in the West Pit Area. All pit disturbance in <br />Section 31 will occur during 1980 as designated in Exhibit 12-2. <br />Highwall reduction and corresponding grading disturbances will <br />terminate in 1981. <br />These disturbances will all occur on Persayo soils. Prior to dis- <br />turbance, six (6) inches of topsoil will be salvaged from these <br />soils to be redistributed on regraded reclamation areas or tem- <br />n <br />
