-36- Since the volume of available topsoil is insufficient to cover the entire disposal site to an adequate depth, suitable replacement topsoil will need to be imported. The operator has committed to importing enough suitable topsoil from a local topsoil dealer to reclaim the entire site. The soil will be analyzed prior to placement to be certain of its suitability. Calculations were submitted to show that 86,000 cubic yards of non-toxic fill material and 10,000 cubic yards of soil cover will be needed at the site. The cost of this material is reflected in the bond amount for the operation. Only one concern was noted with the refuse site that has not been resolved. A small "pocket" of colluvial material exl5ts in the bottom of the refuse site valley north-northwest of the pile. This material will be removed in the future as the refuse pile expands. Since the operator did not analyze the full depth of this material, only the first fea feet, the Division is concerned that the material may nut be suitable for use as cover for reclamation of the pile. As a precaution, the Division lmpose5 the following stipulation: Stipulation No. 2 ALL COLLUVIAL MATERIAL AT THE RUFUSE PILE USED AS TOPSOIL OR NON-TOXIC, NON-COMBUSTIBLE DOVER FOR THE REFUSE PILE MUST BE ANALYZED AND APPROVED BY THE DIVISION AS MEETING THE ESTABLISHED CRITERIA FOR SUITABILITY FOR TOPSOIL AND/OR SUBSOIL. The mine loadout facility was constructed in 1980-82. No additional disturbances are anticipated for this site. Nearly all of the soils disturbed by the loadout were agricultural soils and, as such, are an excellent resource for vegetative reclamation. Prior to disturbance, samples were taken at 11 locations to characterize the soils. The following soil types were identified that were disturbed at the loadout: Aquolls, sandy-skeletal, 1-12 percent slopes Atencio-Azeltine complex, 3-6 percent slopes Armells loam, 12-25 percent slopes Armells load, 6-12 percent slopes Armells loam, 1-6 percent slopes Groubutte stony loam, 25-65 percent slopes Unnamed loam, 1-6 percent slopes Almy loam, 1-6 percent slopes Almy loam, 6-12 percent slopes Cushool-Rentsac complex, 15-65 percent slopes Disturbances from construction of the loadout did not involve area-wide excavations or total destruction of the soil profile, as would occur at a strip mine. Except for specific areas under sediment ponds or conveyor and tipple foundations, loadout construction has involved little significant excavation of subsoils. With the exception of Grobutte stony loam, all of the above soils were salvaged and stockpiled to be reapplied during final reclamation. The only disturbance area that was not stripped at the loadout was at the truck dump site. Here, available topsoil d1d not exist due to the steep slope and barren conditions.
