13. Soil Survey -1988 (PR -02) <br />This was the original soil survey done for the original mine permit area under Peabody Coal <br />Company. The area of the survey is shown on Map 2.04.9 -1. The 1988 survey consisted of the <br />original permit area and a large area to the west. There are no known data sheets for the 1988 <br />survey. Only soil mapping data is available. <br />14. Soil Survey - 1996 (PR -04) <br />As the mine expanded to the west, an additional survey was conducted on the area immediately <br />east of 2700 Road and south of BB Road. The soil survey covered 105.8 acres, including the 100.7 <br />acres added to the permit area as part of PR -04. <br />15. Soil Survey -1998 (PR -05) <br />This survey covered the amendment area west of 2700 Road, and the area north of BB Road and <br />east of 2700 Road. See Map 2.04.9 -1 for the actual area. The soil test location descriptions are <br />typical and consistent for soil in the area. The Order I survey is a refinement of the "not yet <br />published" Order III soil survey that the NRCS has conducted in the area. Detailed map unit <br />descriptions can be found in Attachment 2.04.9 -9, Soil Map Unit Descriptions. <br />The 1998 soil survey did not proceed far enough south on the Morgan Property within the permit. <br />However 1988 soil mapping data is available to confirm soils. The small (11.9 acres) area between <br />the 1998 soil survey (black line) and the permit boundary (magenta line) on Map 2.04.9 -1 does not <br />have soil sample points for depth. <br />Map unit 98A (Begay fine sandy loam) occurs on alluvial terraces formed along Tuttle Draw. <br />Profiles were described to 72 inches. Some areas may have soil deeper than 72 inches and yield <br />a slightly greater amount of salvage material. This unit is considered prime farmland soil as of the <br />2008 NRCS determination. <br />August 2013 (PR 08) 2.04.9 -13 <br />
