• Within the loadout area, the surface disturbance area, as delineated on the Loadout Area Surface Ownership Map, (Map 2), is utilized for mining related operations. Other areas within the loadout permit area are utilized as undeveloped rangeland. Surrounding areas, as shown on the Mine and Loadout Area Land Use Map, (Map 4), are utilized for undeveloped rangeland, pastureland, hay cropping, residential, and limited commercial or light industrial uses. Chances in Land Use Both mining and loadout operations were initiated in 1918 and have continued without significant changes (other than addition of the west loadout area) in affected areas or land uses to the present. Similarly, land uses for adjacent areas have been stable, with land uses over the past ten (10) years consistent with current uses. Within the general area, areas utilized as undeveloped rangeland and • wildlife habitat have been temporarily converted to mining uses or to higher agricultural uses through irrigation. However, there have been no significant changes in land use in the mine, loadout, or adjacent areas over the past five (5) years. Upon completion of mining and related activities, EFCI plans to return disturbance areas to the prevailing land uses of undeveloped rangeland and wildlife habitat which existed prior to development. Land Use Capability/Productivity Land use capability/productivity in the Southfield mine and loadout areas is limited by the relatively arid climate, limited water availability, poorly developed soils, and various socioeconomic factors. With dominant uses of rangeland and wildlife habitat, undeveloped lands exhibit a vegetative production potential of 400-1,600 pounds of air dried • forage per acre. Production for sagebrush/grassland areas is relatively consistent at 1,000 - 1,100 pounds per acre, while production for forested 2.04.3-5
