Vegetation; Predominant vegetation consists (Agropyron cristatum), sand lovegrass (Eragrostis (Neliotus officinalis), sand dropseed (Sporobolus (Bouteloua gracilis) and Russian thistle (Salsola from 25-30 percent and total annual yield ranges hErbage per acre. of crested wheatgrass trichodes), yellow sweetclover cryptandrus), blue grams kali}. Ground cover ranges from 850-950 pounds of air-dry Soils: I4ap Soil Capability Symbol Non-Irrig. Irrig. Series Name and Description 36 IIIe lIIe Haxtun loamy sand, 0 to 3 percent slopes. This is a deep, well drained soil with a grayish brown loamy sand surface texture Range Site: and a grayish brown sandy loam and dark Sandy Plains grayish brown and grayish brown clay loam and loam subsurface texture. Permeability is moderate and available water capacity is high. Surface runoff is slow, water erosion hazard is slight and soil blowing hazard is moderate. This soil is used mainly for non- irrigated cropland. 49 VIe VIe Julesburg - Eckley Complex, 3 to 9 percent slopes. The Julesburg soil is a deep, well drained soil with a grayish brown fine sandy loam 2ange Sites: surface texture and a dark grayish brown, Julesburg - Sandy Plains" grayish brown and brown sandy loam subsoil. -ckley - Gravel Breaks Permeability is moderately rapid and the available water capacity is moderate. Surface runoff is slow, erosion hazard is slight and the soil blowing hazard is moderate. The Eckley soil is a deep, well drained soil with a dark grayish brown gravelly loam surface texture and a dark brown and brown gravelly sandy clay loam subsoil. Permeability is moderate and available water capacity is moderate. Surface runoff is rapid and erosion hazard is high. These soils are best suited for grazing. EXHIBIT E - Reclamation Plan Landscape Design: After mining is complete, the area will be shaped and graded. Where possible, final grading should be done on the contour to conserve moisture and reduce erosion. Slopes should be rut or filled so that no slope is greater that 3:1. Seeding success will increase if lesser slopes remain. The land will be scarified to a depth of 6 inches following grading to provide better cohesion between topsoil and the graded area.
