The eleven types of natural soils on the site as determined by the Natural Resource Conservation Service and shown in the report are designated as map Units 1, 2, 3, 10, 16 , 21, 22 , 38 , 42 , 52 , and 76 . Soil units 38 and 76 are very small areas on the edges of the mine that will not be mined. See the soils map in the NRCS report for how the soils are distributed on the permit area. The NRCS report contains detailed information including the soils description, and chemical, physical, and engineering qualities, which can be found in EXHIBITI-SOILS. The Vegetation inventory applies to only the non-farmed area in each soil type and is provided as background for when the perimeters of the lakes and backfilled areas are revegetated. Typically, at this time, the irrigated areas are used to grow various crops, such as corn, wheat, barley, sorghum or sunflowers .
