Section 779.21 (a) Continued. <br />• <br /> mmhos/cm for the Kline No. 1 area. Energy Fuels' values obtained in <br /> Eckman Park, ranged from 0.3 to 3.0 with an average of 0.9 mmhos/cm. <br />Only one sample exceeded the value of 4 mmhos/cm, Table 79, <br />Suitability Ratings for Soils as Sources of Topsoil, that being <br />encountered in a highly calcareous zone of subsoil. The salinity <br />hazard of these soils according to Richards (1969) would be "none <br />to slight" for salt sensitive plants. The topsoil suitability <br />guidelines recommended. by the Wyoming DEQ indicate all topsoils in <br />the permit area are considered "good" with respect to the criteria <br />of electrical conductivity. <br />Saturation Percentage. A total of 91 samples were analyzed for <br />saturation percentage. The U. S. Forest Service found a range of <br />43% to 72% with an averagc of 55.8% for soils on Energy Mine No. 1. <br />Along Fish Creek, saturation percentage values ranged from 40 to <br />• 78.7 with an average of 52.4 percent. In Eckman Park, values <br />ranged from 21.6 to 40.1 with an average of 29.6 percent. In that <br />tract only 6 samples were below the recommended Wyoming Department <br />of Environmental Quality value of 25, (See Table 80, Wyoming DEQ <br />Guidelines for Suitability Ratings for Soils as Sources of Top- <br />soiling Material). The values for these six samples are close <br />enough to 25 that any mixing will push them over this threshold. <br />For this reason, the soils encountered in the permit area are <br />considered "good" with respect to saturation percentage. <br />Particle Size. A total of 92 samples were analyzed for texture. <br />Heil (1976), was of the opinion that of the 17 soils he sampled, <br />all would be classified as "good" for topsoil (See Table 77, <br />Particle Size and Moisture Content Analysis of Soil Horizons <br />Sampled by Heil (1976). Using the Wyoming DEQ criteria for the <br />same 7 samples, 4 were rated "good" as topsoil and 3 were rated <br />"fair". <br /> <br />779-292 <br />
