June 25,2012 C-1982-057/Seneca II-W Mine SLB <br /> The mud flow and slide at the pump house was stable and vegetated. The underdrain of the slide was dry. <br /> The area around Pond 006,where several cracks had appeared between the facilities area and the pond was stable. <br /> No new cracks or slumps were observed. <br /> The Pond 016 slide area remediation is nearly complete. The lower ends of postmining channels PM-2, -2A, -213, <br /> and 3 were all complete. It appeared that an equipment crossing had been constructed in PM-2,between Road J <br /> and the junction of PM-2 and-2A,covering the rip rap. This portion of the channel will need to be repaired. <br /> Otherwise,the newly constructed portions of the drainages were in excellent condition. It appeared that <br /> construction of the ditch that runs at the base of the regraded road cut slope,on the north side of Road J over the <br /> constructed underdrain,was not yet complete. It should be graded to ensure positive drainage and avoid ponding <br /> in the area. <br /> The pit ramp slide was also stable. Downdrains in the slide had been constructed,but not yet armored. The <br /> channels are approximately 4' deep with vertical sides that are collapsing in places. The two channels will need <br /> to be filled with rock to ensure that water will flow through the channels and prevent clogging with sloughing <br /> sideslope material.Also,on the west end of the toe bulge,there is a low area where water will collect that should <br /> be graded for positive drainage. It appears that about 20' of ditch will need to be cut to connect to the west <br /> downdrain. <br /> ENFORCEMENT ACTIONS/COMPLIANCE <br /> No enforcement actions were initiated as a result of this inspection,nor are any pending. <br /> PHOTOGRAPHS <br /> Reduced slope north of Road J <br /> Number of Partial Inspection this Fiscal Year: 15 <br /> Number of Complete Inspections this Fiscal Year: 4 <br /> Page 3 of 4 <br />
