.7 <br />• <br />For the 10.88 acres of the permit area which has previously been dis[urbedl <br />the necessary quantity and quality of cut material (soil and overburden) for reclam~ <br />stockpiles in the upper reaches of the east drainage area below [he plateau (Topsoi <br />Map C-4). <br />This soil material was obtained from an area around and above [he shop bu <br />storage area prior to 1972. It has overgrown with natural vegetation, and is therefc <br />protected adequately from wind and water erosion. The upper reaches of the east t <br />which stockpiled topsoil lies is included in the disturbed area shown on Map C-4. <br />Area consists of an area of 1.5 acres with an estimated average depth of 7 feet, or <br />cubic yards of material. This area has been sampled and analyzed by the soils lab ; <br />University. For results of these analyses, see Appendix 9(4)(a). The azea under su <br />require replacement of topsoil; however, all areas disturbed by retnoval of topsoil <br />the same manner as described for mine disturbed area in Section 2.05.4. <br />Suitable. plant growth medium (subsoil) should also be obtainable from the <br />overburden and embankment material. These soils have also beets sampled and an <br />lab at Colorado Stale University (See Appendix 9(4)(a)). Stockpiled soils (Subsoi, <br />free from contamination with stockpiled coal and are located so as to eliminate ero <br />soils (See Map C-4). Reclamation of the permit area would commence at the end ~ <br />mine. <br />RECLAMATION SOILS <br />All stockpiled topsoil plus the suitable overburden/sediment pond material <br />reclamation will be tested for the following parameters: <br />1. Ph <br />2. Conductivity <br />3. Texture (particle size distribution) <br />4. Sodium absorption ratio <br />5. Saturation percentage <br />6. If Ph is over 8, test will be made for selenium and boron. <br />7. Fertilization: <br />Nitrogen <br />Phosphot~ts <br />Potassium <br />8.
