III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />This was a complete inspection of the Seneca II-W Mine conducted on June 12, 2001 and June <br />l3, 2001 by Mike Boulay of the DMG. Roy Karo and Mike Altavilla of Seneca Coal Company <br />were present during the inspection on June l2th and June 13`", respectively. Weather conditions <br />were cloudy and cool. Ground conditions were damp throughout the majority of the site. <br />Hydrologic Balance <br />All site sedimentation ponds were inspected and appeared to be functioning properly. Ponds <br />005, 006, and 009 were retaining water but not discharging. Ponds 015 and 016 were full and <br />dischazging clear water at the time of the inspection. <br />The B Pit pre-settling basin was holding water but was not discharging to its spillway. The <br />culvert located below the pre-settling basin will need to be cleaned out in the neaz future. The <br />discharge end of this culvert is partially full of sediment. To ensure compliance, please continue <br />to maintain culverts throughout the mine site. <br />Topsoil <br />The eastern perimeter of the South Area pit at the location of NOV CV-2001-002 was inspected. <br />Mitigation measures are underway to abate the violation at this location. The area was inspected <br />from the top of the ridgeline where blasted material was cast onto undisturbed ground, and from <br />below the slope accessed by a temporary road from Pond 015 up to the base of the slide area. <br />At the top of the ridgeline and immediately north of the slide area, it was noted that a small <br />slump and crack has formed in the heavily brush covered area along the disturbance boundary <br />line. Although this was not noticed during the last inspection, it appears that the crack may have <br />formed as a result of the blast that created the disturbance associated with NOV CV-2001-002. <br />Please monitor the crack and small slide at this location and inform the DMG of any additional <br />movement or damage that may result. <br />To date, the blasted material that was cast down the steep slope has been removed by trackhoe <br />and dozers. With the exception of the base of the slope, the area has been regraded. At the base <br />of the slope, topsoil that was disrupted by the slide has been segregated and stockpiled. Larger <br />rocks, brush and downed aspen trees remain at the base of the slide area. Based on site <br />observations and consultation with SCC personnel, it was determined that the larger rocks and <br />downed aspen trees could not feasibly be removed from the base of the slope. This is due to <br />limited access for equipment and steepness of the slope. <br />
