(Page 2j MINE ID ~ OR PROSPECTING ID {t M-SO-228 INSPECTION DATE 4/20/99 INSPECTOR'S INITIALS RCO OBSERVATIONS This inspection was performed by the Division as part of its monitoring of Construction Materials 112 permits. A problem was noted during the 12!10/98 inspection, which was to be corrected. This inspection was to verify that the problems were adequately corrected. The operator was contacted about the inspection several days prior to the inspection, and stated to this inspector that it would be permissible to inspect the site at any time. A definite date was therefore not arranged. The operator's representative named on page one was present throughout the inspection. The site is identified by a permit ID sign posted on a wooden shack near the scale along the entrance road. The sign contains all the required information, but the future of the shack is in doubt. The shack appears to be rather dilapidated or unstable, and if it is removed, the sign will need to be replaced in another location. At this time there is no problem. The primary road into the pit and plant area is in good condition, but the secondary road is now impassable. Piled material and a runoff containment pond now occupy the road's farmer location. This is not a problem, but the operator should ensure that both the pond and stockpile are stable and will not contribute to offsite damage from failure or sloughing. The north end of the permit area has received a significant amount of reclamation during the last few months. The highwalls have been reduced to the specified gradient of 3:1, and the bermed topsoil has been replaced on those slopes. There are no more topsoil piles around the north end of the pit. The pit floor has been cleaned up and levelled. Except for a small concrete wash sump and a small pile of topsoil, the pit floor is clean. The operator stated that the small pond will be filled soon, and another area will be prepared for a permanent wash location, then the pit floor will be ready to be a permanent product stockpile area. The new slopes show no sign of thistles yet, and that must be monitored during the reclamation period. The operator stated that this fall the slopes will be seeded for final reclamation. The operator is commended for the good job of reclamation in the north end of the pit. Regarding the features noted as a problem at the last inspection, the leaky drums and buckets of oil, plus the other debris, in the pit have been removed, and all traces of contaminated soil are gone. The elevated fuel and oil tanks are in a more stable location, and an adequate containment berm has been built around them. The Division considers that the pre-existing problem has been corrected. The south end of the permit area receives the collected runoff from the plant area. There is a continuous earth berm around the edge of the pad, and a sump created at the edge of the bermed area. There is no discharge, but the pond shows signs of percolation or evaporation of the water. The higher portions of the berm may be removed soon, to be used as growth medium on parts of the permit which may be reclaimed soon. Parts of the berm may be removed without compromising the containment of runoff waters, since the outslopes are stable, and the active pad surface slopes inward toward the catchment basin. There are still several drums of waste oil on the site, but they are next to the plant building in a bermed location. The oil is used as fuel for the onsite furnace. Likewise there are some other bulk containers with liquid concrete admixture on the site. The storage locations are not likely to be in the way of site traffic, and they are bermed to provide secondary containment. The operator stated that when the plant becomes fully operational, permanent storage locations for all fuels, fluids and wastes will be built, some with concrete stem walls. There were no problems noted during this inspection. Due to the significant amount of earthwork recently performed, the operator may wish to request a bond reduction. If so, the steps described in Rule 4.16 should be followed. At this time, the bond is considered to be more than adequate.
