As summarized on this report, this survey reported that the SCS (now NRCS) had <br />mapped, sometime prior to the 1979 field survey, two different soils mapping units <br />within this area, mapping unit 5810, Shavano sandy clay loam and soils mapping unit <br />9904, Persayo sandy clay loam. This evaluation resulted in the formal sampling of six <br />undisturbed soils locations and six topsoil stockpiles. Formal soils profile descriptions, <br />using SCS form 232G were recorded on these sites. The mapping from this effort is not <br />reproduced since the soils mapping unit names and descriptions were changed by the <br />NRCS in the final soil survey. The locations of the six undisturbed soils samples, labeled <br />as S1 through S6 and the five topsoil stockpiles, labeled as SP5 through SP10 sampled in <br />this effort are shown on Map 2.04.9 -2, New Horizon North Mine - Soils Map and on Map <br />2.04.9 -3, New Horizon North Mine - Topsoil Salvage Map. <br />The results obtained from the sampling of the 18 parameters evaluated from the 16 <br />samples of undisturbed soil material analyzed are presented in Table 2.04.9 -1, 1979 <br />Laboratory Analysis of Undisturbed Soil Samples. Subsequent to the analysis of these <br />samples, five of these sample sites were disturbed by mining As a result only sample <br />site 79 -3 is still undisturbed. However these data are indicative of the characteristics of <br />the soils materials that were salvaged and used for reclamation on the Rice Tract. <br />The results obtained from sampling of the 16 parameters analyzed from six topsoil <br />stockpiles sampled in 1979 are presented in Table 2.04.9 -2, 1979 Laboratory Analysis of <br />Topsoil Stockpiles on the Rice Tract. The analysis of composite samples from these <br />topsoil stockpiles for coarse fragment content and metals is found in Table 2.04.9 -3, <br />Composite Analysis of Topsoil Stockpiles on the Rice Tract. The data are representative <br />of the soil material that was used to reclaim the 65.55 acres of topsoiled reclamation <br />found on the Rice Tract and shown on Map 2.04.9 -2, New Horizon North Mine - Soils <br />Map. <br />1978 -1984 NRCS SOILS SURVEY <br />The Natural Resource Conservation Service (NRCS), in cooperation with the Colorado <br />Agricultural Experiment Station (CAES) and the United States Department of the <br />Interior, Bureau of Land Management (BLM), has published an undated on -line soil's <br />survey entitled Soils Survey of San Miguel Area, Colorado Parts of Dolores, Montrose <br />and San Miguel Counties that covers the entire project area. According to the preface of <br />this report, the major portions of the field work were completed in 1978 -1984 and this <br />report is based upon soils names and descriptions approved in 1986. This survey is <br />reported to represent conditions in the survey area in 1986. According to a February 11, <br />2008 letter from the NRCS Soils Scientist in Montrose, addressing the nearby New <br />Horizon Mine, this survey was probably <br />Section 2.04.9 Page 2 November 2011 <br />
