s These values may vary depending upon the plant species proposed for revegetation in specific <br />locations (e.g., a soil with a high coarse fragment content throughout its profile may be completely <br />salvaged if used for rangeland versus cropland postmine land use). <br />These suitability evaluations, based on averages across the study area, were used fortopsoil volume <br />determinations presented in the Topsoil Management Plan section of Section 2.05.4(2)(d), Topsoil <br />(Redistribution). The number of profiles on which these averages are based is noted in the Soil <br />Profile descriptions range of characteristics. The recommended topsoil salvage depths for each map <br />unit are weighted averages of each major component of the map unit (those listed in the map unit <br />name -for both consociations and complexes) as well as majorsoil inclusions as presented within the <br />map units. <br />ResultslDiscussion <br />Prime Farmland Determination -1988 and 1998 <br />The Norwood office of the NRCS has provided WFC with documentation that list the definitions and <br />criteria for categorizing soils as prime farmland, see Attachment 2.04.9-4 and Attachment 2.04.9-5. <br />These documents list the standards set by both the U.S. Department of Agriculture, Natural <br />Resource Conservation Service and the State of Colorado, Natural Resource Conservation Service. <br />Peabody Coal Company and Intermountain Resource Inventories Inc. conducted soil surveys and <br />the results can be found in Map 2.04.9-1, Attachment 2.04.9-1, Attachment 2.04.9-2, and <br />Attachment 2.04.9-3. Soil type 70B and D706 lists Barx soil as a major component and Barx as <br />a secondary component (30 percent of map unit) in 98E on Map 2.04.9-1. Barx soil is listed as a <br />prime farmland soil in San Miguel County if the soil is irrigated by an adequate and dependable <br />water supply. A letter dated October 14, 1992 (Attachment 2.04.9-6) from the Norwood NRCS <br />representative states there is no prime farmland in this location because Barx soil does not have <br />an adequate or dependable water supply for irrigation. Soil type 70B and D70B were covered under <br />the 1992 letter. Soil type 98E is a resurvey of the original 708 soil type covered in the 1992 letter. <br />Conclusion: there is no prime farmland soil types in the WFC permit boundary. <br />(Revised 2/00) 2.04.9-11 <br />
