GBEA Wagner Pit#M2023038,Owner&Operator:Twin Buttes Land Co LLC 04/10/2024,Page 10 of 65 Site Description, Exhibit B The description of the site will address soil, plant community and vegetation, man-made structures, water resources, and wildlife. Small maps pertaining to specific topics will be included and master maps can be found in the Map Exhibit E. Soil and Vegetation (a) Soil The pit straddles two soil types and are in keeping with the distribution of the parent material as shown in the geology. Map B-1 displays the soil spatial distribution at a much finer scale than the original NRCS maps. One should keep this is mind when interpreting the spatial distribution of the soil. See Appendix B for a complete soil description. Blazon, Map Symbol 10(Map B-1) Land forms are ridges with slopes upwards of 40%. This comprises 50%of the area with Rentsac 35% and minor components at 15%. The Rentsac is a very channery loam, 0 to 5 inches, a very channery clay loam 5 to 16 inches and then an unweathered bedrock begins at 16 inches. Slopes for the Rentsac are upwards of 65%. The two soils are intermingled spatially and it is not practical to map them separately. The ecological site is Mountain Pinyon for the Blazon and Upland Shallow Stony Loam for the Rentsac (Bonneville Big Sagebrush). Both soil types are well drained, with high run off Tisworth, Map Symbol 89(Map B-1) Land forms are fans and valley floors with slopes up to 5%. The parent material is high content gypsum and alkaline salt alluvium derived from sedimentary rock. Within 4 inches of the surface it is a sandy loam, 4 to 11 a clay loam, and 11 to 60 a gravelly loam. The ecological site is Alkali Flat(greasewood). It is well drained,with medium run off. Current Pit Soil Condition The 1964, Texas Mountain, USGS topographical map, 1:24,000, has a gravel pit marked at the Wagner pit location. With a minimum of 60 years of mining history, the original soil at the location has been extensively disturbed. Some locations have recovered with mature vegetation and the soil is relatively healthy, while others areas are "raw". There are no apparent stock piles of soil that have been harvested in the past for future usage. This lack of healthy soil will be a concern in future reclamation and seeding. The reclamation plan will address this issue.
