• (Page 21 • MINE ID # OR PROSPECTING ID # M-77-568 INSPECTION DATE 10/12/99 INSPECT'OR'S INITIALS RCO OBSERVATIONS This inspection was performed by the Division as part of its monitoring of 112 Construction Materials permits. The operator was contacted about the inspection and was present throughout the inspection. The permit ID sign was posted at the entrance to the site, and the permit boundary was adequately marked by fenceline on the northeast, and fenceposts on the southeast, southwest and northwest corners. Though the boundaries and/or corners are considered adequately marked (while the mining is only in Phase 11, the operator should r~nsure that the actual boundary is clearly and fully delineated on the ground as the pit grows. This is because the fencelines are well beyond the boundary on the east, south west and northwest. Offsite damage is a possible violation, and can be easily prevented here. The permit was converted to an 80-acre 112 permit in 1995-96, with a phased mining plan. The operation is still in phase one. Mining is ongoing in the northeast part of the permit area, with processing and stockpiling occurring in the pit and to the west of the pit. The crusher has been moved out of the pit and to another site. Onsite equipment included an asphalt plant (currently inactive) and "sand drying plant" (for preparing winter road aggregate). Both are set up on the processing pad west of the pit. This stationary equipment is propane powered. The wheeled and tracked equipment is diesel, and a fuel tank is set up there with the proper secondary containment. The site exhibits no oil- or fuel-stained soil, no dilapidated equipment or parts, no trash and no noxious weeds. The topsoil is stockpiled along the top of the north and south pit margins. It appears to be of sufficient quantity to perform the approved reclamation. At this time, there has been no reclamation, though disturbance is being carefully limited as mining needs grow. Topsoil is stripped prior to mining. The pit highwalls are currently vertical, about 15 to 20 feet high. The site is being operated in an orderly manner. There is a significant stockpile of natural and crusher fines being kept in the northern part of the pit floor, which will eventually be used for backfilling against the pit walls to attain the approved gradient for reclamati~~n. There were no other items noted, and no problems at this site.
