n \J MINE ID ~ OR PROSPECTING ID INSPECTION DATE 06/15/95 (Page 2) M-95-026 INSPECTOR'S INITIALS RCO This was a pre-operation inspection performed by the Division, ae required for all 112 applications. The operator's representative named on page 1 was contacted about the inspection, and was present for it. In addition, the NRCS conservationist, Alex Parrott, was present during the inspection also. The representative from the engineering firm, who has largely been responsible for the preparation of application materials, was not able to be present. The proposed permit area is a 40.25-acre block, located adjacent to the west edge of the county-operated landfill. There ie no existing Bite disturbance, other than the following: a number of small teat pits observed in the south-central portion of the site; a short length of drainage diversion ditch cut across the north aide and ending in a swale in the northwest portion of the site; and the road to be used to acceae the mine operation, which road currently exists as an alternative entrance to the adjacent landfill. There ie presently a locked gate on the north end of the acceae road. The above-mentioned diversion enters the permit area from the east and passes under the access road through a 15-inch CMP. The permit sign will be installed near the gate. The permit area ie fairly level across the north and east portions, and drops away sharply on the south and west. The operation will begin at the lowest point of the tract, in the southwest corner. The mining will proceed to the north and east, beginning and staying on the grade of the pit floor. Slopes of 3:1 will be maintained during the mining phase, by pushing material down from the top. Drainage will be to the SW, with sediment control structures installed and maintained throughout the mining phase. They will be removed after reclamation has stabilized the site. There is approximately 30 to 40 feet of vertical drop throughout the permit area. The natural ephemeral drainage to the south, outside of the permit area, has an earthen dam constructed across it. The southeast portion of the site presently drains into the pond behind the dam. This land is also owned by Custer County. The operator must be aware of the chance of increased sediment loads after the surface is disturbed by mining. Appropriate measures must be implemented for controlling sedimentation, especially that which could affect areas outside the permit boundary. The site vegetation can presently be described ae the typical, diverse rangeland species, though not abundant in grasses. The soils on the site range from fairly thin with cobbles visible on the surface, on the south eloping areas, to deep soil free of rocks or cobbles on the central and north portions. (A teat hole was dug during the inspection, and a loamy soil was found to a depth of more than a foot). All available topsoil should be salvaged and preserved according to the plan. This site stands a good chance for quick recovery due to the abundant soil. These items were discussed with the applicant during the inspection. There were no problems observed at this time.
