• Soil analysis results for the Southfield loadout area are summarized in <br />Table 26, Loadout Area - Soil Chemical and Physical Lab Analyses. <br />Suitability Evaluation - Mine Area <br />This suitability evaluation concentrates on areas to be disturbed by <br />surface activities. Soil samples from pits 1 through 10, the road cut <br />sample, and the stockpiled topsoils were included in this evaluation. <br />Since soils will be mixed during removal and redistribution, a single <br />composite value for topsoil suitability has been calculated. Horizon <br />designations were obtained from the information presented in Table 24, <br />Mine Area - Soil Chemical and Physical Lab Analyses. Stockpiled topsoils <br />were all considered to be "A" horizon soils. The following evaluation <br />discusses the materials to be disturbed in relation to pH, electrical <br />conductivity, sodium adsorption ratio, saturation percent, texture, clay <br />content, and trace elements. Minimum, maximum, and mean analysis values <br />• along with the standard deviation are presented in Table 27, Statistical <br />Evaluation - Topsoil Suitability. <br /> <br />Overall suitability for each soil horizon is presented in Table 28, <br />Topsoil Suitability Comparison. Values of pH between 6.0 - 8.4 are <br />considered to be "good" relative to topsoil suitability. Approximately <br />88 percent of the A horizon soils and 100 percent of the B horizon soils <br />fall within this classification. Therefore, soil pH should not adversely <br />affect revegetation. <br />Electrical Conductivity (ECl <br />Electrical conductivity values under 4 are considered "good" relative to <br />topsoil suitability. All A and B horizon samples tested fell within this <br />classification, so EC is not a suitability concern. <br />• <br />2.04.9-21 <br />
