Revised 11/15/81 the site specific suitability of each major soil horizon for all three soil types which may be removed is shown in Exhibit 11, Soils Information. Depths to which topsoil and subsoil will be removed prior to disturbance are shown on the Soils Map (Map 10). 2.04.10 Vegetation Information A vegetation map has been prepared which shows the area- which is affected by the Maxwell Mine surface facilities and additional area which will be disturbed within the permit term. The various plant communities are delineated based on aerial mapping and field mapping which has been completed by Uniscale, Corporation. Uniscale has conducted two extensive surveys of the areas around the surface facilities to determine species composition, cover, productivity, and woody plant density. A Vegetation Map (Map 11) has been prepared which delineates each plant community. In addition, the reference areas which have been selected are also shown on Map 11. The area which the surface facilities of the Maxwell Mine currently occupies was disturbed in 1976. Vegetative baseline information was not collected prior to disturbance of this area. However, adjacent areas to the permit area have been sampled to determine the species composition, cover, productivity, and woody plant density and are statistically compared with the selected reference areas. Methods which have been used to sample the existing plant communities and select the reference areas are discussed by Uniscale and shown in Exhibit 12, Vegetation Information. During the sampling and field work conducted by Uniscale, no rare and endangered plant species were encountered. Therefore, no impacts of these species are expected. Due to the small area which will be disturbed during the term of the permit, relatively little impact of any plant species present is expected. 2.04-15
