• It is estimated that soil could be removed from 8.3 acres and will result in <br />approximately 90,000 cy of salvaged material. If the salvage operation were to <br />occur, sampling would be done on approximately 200' spacing and a 2' depth <br />intervals to define topsoil, subsoil and stripping limits. Material which meets the <br />SAR and EC limits defined for topsoil overburden in Tab 14 would be <br />segregated in Topsoil Stockpiles 12a and 12b. Soil salvage at CRDA 3 is not <br />planned since the mine is idle and not expected to operate again. Soil sample <br />analyses can be found in Table 9, Appendix 9-4. Sample locations can be <br />found on Exhibit 52. <br />Storage <br />Due to the long-term nature of surface facilities and operations disturbance, <br />topsoil removed in association with these disturbances will require stockpiling for <br />the most part. In cases where direct hauling of salvaged topsoil is practical, <br />every effort will be made to do so. <br />• Redistribution <br />Details regarding replacement of direct hauled or stockpiled topsoil/subsoil <br />material is described in Tab Section 20. <br />Reconditioning <br />Based on the physical and chemical characteristics obtained from sampling, all <br />of the topsoil stockpiles are suitable for sustaining plant growth with minor <br />amendments as necessary. The soils are, in general, sandy loams, which will <br />allow suitable drainage if the subsoils are well drained. The soils are quite friable <br />and preliminary testing indicates no toxic concentrations of any element are <br />present. Generally, the soils of the area are deficient with respect to nitrogen, <br />phosphorus, iron and occasionally zinc. <br />• 13-19 (Rev. 1 /00 ) <br />
