2.04.9 Soils Resource Information <br />Four SCS (now NRCS) soil mapping units occur within the originalpermit area (Map 4- <br />5). They are in order of importance to soil salvageand final reclamation:1) the R8-CD <br />Falfa clay loam, 3 to 8 percent slopes, 2) the XE6-E Zyme-Rock outcrop complex, 12 to <br />65 percent slopes, 3)the XTO-E Ustic Torriorthents-Ustollic Haplargids, 12 to 60 <br />percent slopes, and 4) the RL-Rock outcrop containing little soil. SCS soil descriptions <br />4-5 <br />are contained in Appendix . Typical soil horizon depths for the permit area soils from <br />pedon descriptions are: <br />SCS Map UnitSoil Series___Horizon Depths (inches)_____________ <br />ABC <br />R8-CDFalfa clay loam47680 <br />XE6-EZyme-Rock Outcrop <br />Complex600-14 <br />(clay) <br />XTO-EUstic Torriorthents6-8" total <br />Ustollic Haplargids <br />RLRock Outcrop3" total <br />Samples of each of the four soils were selected for analyses. The samples were collected <br />with a shovel, placed in plastic bags and transported to CDS Labs in Durango (See Map <br />4-5Soils Mapfor sample locations). Samples 12 and 13 were obtained with use of a drill <br />rig. Results of the analyses are contained in Appendix 4-5.The analyses indicate that all <br />soils sampled apparently possess characteristics suitable for stockpiling and eventual <br />redistribution with appropriate soil amendments. The clay percentage of these soils is <br />greater than desired. Additionally, the soils are uniformly deficient in phosphorous and <br />nitrogen. These problems will be overcome with mulch (to improve soil structure) and <br />fertilizer applications. The fertilizer application rate will be determined from soil tests of <br />redistributed soil during reclamation. <br />Soil material suitability for salvage and reclamation is shown on Table 4-7. Falfa clay <br />loam could be stripped to six feet based upon sample analyses 1, 5, 10, 11, 12 and 13. <br />The Zyme-Rock outcrop complex could be stripped to 6 inches where possible based on <br />Samples 2 and 6. Salvaging any deeper in this soil will contaminate the thin A horizon <br />with clay and shale. The exception to this recommendation is considerable deposition of <br />this soil that has occurred in the Carbon Junction Canyon bottom for a width of 57 feet. <br />In this area, soil should be salvaged to a depth of 24 inches (Samples 4, 7, 8 and 9). <br />Analysis of the Ustic Torriorthent -Ustollic Haplargids Series indicate 6 inches should be <br />salvaged (Sample 14). However, this soil occurs sporadically in pockets of sandstone <br />and is sandy, gravelly and cobbly. In addition, the Rock outcrop soil, 3 inches total <br />depth, cannot be practically salvaged with existing heavy equipment.
