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 Yoast Mine conducted on August 20, 2002 by Mike <br />Boulay of the DMG. Robert Shevling of Seneca Coal Company was present during the entire <br />inspection. Weather conditions were cloudy and warm. Ground conditions were dry throughout <br />the majority of the site. Coal was not being hauled from the mine site at the time of the <br />inspection. The dragline was operating in the Yoast South Area. <br />Availability of Records <br />All required records were on file and available for review at the mine site office. No problems <br />were noted with the records review. Please see the attached Availability of Records checklist. <br />Roads <br />Road surfaces throughout the mine site were dry and in good condition. Haul Roads A, B, and D <br />were very well maintained. Road ditches and road drainage nmouts were dry. Culverts along <br />Haul Roads A, B, and D were maintained and functioning properly. Culvert D-4 has been <br />replaced on Haul Road D. The road drainage runout that receives the outflow from Culvert D-4 <br />has been bladed and a berm has been built up in front of this ranout. Please consider removing <br />the berm at this location. This drainage runout serves an important function in keeping runoff <br />away from the outslope above Pond 012. Keeping surface water runoff away from the slide azea <br />below the Haul Road D embankment is a critical component of the mitigation plan for the slide <br />that occurred at this location. <br />Hvdroloeic Balance <br />Sedimentation Ponds 010, 011, 012, and 014 were inspected. Ponds Ol 1, 012, and 014 were <br />retaining water but were not dischazging at the time of the inspection. Pond 010 has been <br />drained in prepazation for cleaning and sediment removal. The sediment level is approximately <br />1.5 - 2 feet below the level of the primazy spillway. Minor Revision No. 18 was submitted for <br />the construction of a temporary access road on the south side of the pond. The access road will <br />be used to haul the sediment away from the pond and into an active pit area. MR-18 was <br />approved on August 26, 2002. <br />The inlet to Pond 011 was recently repaired. A liner and additional riprap were installed at the <br />inlet to Pond 011. A recent rainstorm has completely removed the liner and most of the riprap <br />from the inlet. The inlet and resultant erosion needs to be repaired as soon as practicable. Please <br />be sure to install the liner properly by keying the liner in at the entrance and exit points and along <br />all sides of the liner prior to placement of the riprap. <br />
