1 <br />2.09.9 (1) (a) <br />• Permeability is moderate and the available water capacity is <br />6.4 inches. The effective rooting depth is 40 inches. Surface <br />runoff is low and erosion hazard is slight from wind and moderate <br />' from water. <br />(b) Soil Analysis. <br />Figure 2.04.9 (1) (b)-1 is an analysis of the topsoil from the Bear Coal Pine <br />stockpile located just west of Sedimentation Pond No. 2. <br />(i) pH 7.9 <br />' (ii) Salinity is 5.05 P^_mhos/cm <br />(iii) Sodium Absorption Ratio = 1.5 <br />1 <br />{iv) Texture = Sandy loam, coarse, less than 18-percent clay <br />' (c) Soil map. <br />Refer to Drawing 2.04.9(1)(c)-1 for the soils map. The map <br />shows the soil type on the disturbed area as well as soils on <br />' the balance of the permit area. Soil types on the balance of <br />the permit area are for information purposes only. Soils are <br />classified as follows: <br />1 <br />109 E, Absarokee - work loams <br />101 F, Beenom - Absarokee Association <br />02, Torriorthents - Haplargids Complex, very strong. <br />R1, Rockland - Sandstone and shale <br />No topsoil stripping is proposed. The permit area has been previously <br />disturbed and has been utilized, almost in its entirety, for support <br />activities of the mining operation. The area contains the mine office, <br />shop, warehouse, waste pile, stockpile and loadout facilities. These <br />uses have been in effect since the beginning of the operation. <br />1 <br />The topsoil to be used will come from existing stockpiles. <br />' S2 <br />P,E'IIST'D i•Iay 15, 1981 <br />
