TR-76 2.04-36 (revised 6/7/2022) <br />because of prior disturbance. However, where possible, the available soil <br />resources have been mapped and tested. The soil resources of this area <br />have been mapped and sampled to determine the amount of soil which is <br />available for removal. In addition, sampling and chemical analysis of this <br />soil material has been completed. Mapping and sampling of the soil <br />horizons in areas which will be disturbed by the surface activities has <br />been conducted by the Soil Conservation Service located in Trinidad, <br />Colorado. Because the Haul Road (TR-76) is already in a previously disturbed railroad bed <br />soils will not be impacted. Analyses of the various samples shown on Map 9, Soils, are <br />located in Exhibit 14, Soils Information. In addition, the description of each soil type which <br />will be disturbed is included in Exhibit 14. Locations of soil samples are shown on Map 9, <br />Soils. Additional narrative for all three soil types which may be removed is shown in <br />Exhibit 14. <br />During the spring of 1984, a soil survey was conducted to identify <br />the extent of the soil resources and their suitability as a plant growth <br />medium on the proposed Refuse Disposal Area (RDA) and Preparation Plant <br />Area (PPA). Existing Soil conservation Service (SCS) unpublished soil <br />survey of the area was used as a field guide during the site evaluation. An ortho-photo <br />(scale 1:6000) was used as the base map for soil mapping in <br />the study area. Preliminary mapping boundaries based on topographic <br />location, vegetation types, geologic features, and the previous soil survey <br />were delineated on the photo. <br />The area was traversed on foot to inspect soils. Surface <br />observations and inspection of subsurface soils was obtained with a <br />manually operated soil auger were made to verify soil type changes along <br />the landscape. The soils that were observed were correlated to those <br />previously described by the SCS. The mapping unit descriptions are also <br />consistent with those developed by the SCS. <br />Soil samples were taken in the proposed refuse disposal area to <br />characterize the physical and chemical suitability of soil. All samples <br />were taken in the area mapped as Rombo soil because this soil type will <br />have the greatest areal disturbance. Samples were taken with the soil
