<br />I. General Comments Continued <br />The bulkhead seal and associated doorway at the Anchor seam conveyor portal <br />were inspected to determine whether the closure was adequate to prevent entry <br />into the workings by unauthorized persons. It appeared that the small opening <br />surrounding the conveyor belt had been vandalized recently. The wire mesh <br />screen bolted to the metal bulkhead had been cut and pried open such that <br />entry into the workings was possible. This portion of the bulkhead needs to <br />be sealed immediately to prevent unauthorized persons from entering the <br />mine. It is suggested that a steel plate or series of iron bars be welded or <br />bolted to the steel bulkhead as soon as possible. <br />Runoff from the coal stockpile area located below the anchor seam portal bench <br />has deposited coal fines in the drainage channel leading from the stockpile <br />area to the sediment pond at the south end of the surface facilities area. A <br />filtering system such as silt fencing or hay bales needs to be placed along <br />the southern edge of the stockpile pad in order to prevent excessive <br />quantities of coal fines from being deposited in the drainage way. <br />Additionally, a berm of non-coal earth material should be installed along the <br />southern perimeter of the coal stockpile pad to ensure that coal fines and <br />stockpiled coal are prevent from being washed over the out slope of the <br />stockpile pad area. This will involve pulling back or removing the coal <br />material from the edge of the pad. <br />The small drainage ditch controlling runoff from the southern end of the gob <br />pile needs to be cleaned out and a positive gradient established in order to <br />prevent water from pooling at the base of the gob pile. The ditch should be <br />reconstructed to a point where runoff will travel directly to the sediment <br />pond southeast of the gob pile. <br />The topsoil and subsoil stockpiles at the southeastern extremity of the mine <br />site appear stable and are covered with a healthy stand of vegetation. <br />Topsoil markers are in place and clearly visible. Mine entrance and perimeter <br />boundary markers are also in place and visible from a distance. <br />Both sediment ponds were dry and contained relatively small quantities of <br />sediments given the amount of storage volume provided for their retention. <br />Dewatering devices functioned properly, emergency spillways were free of <br />debris, and sediment clean out markers were in place. <br />Revegetation on the abandoned farmer's mine reclaimed area just east of the <br />coal stockpile pad appears to be progressing well. No evidence of slope <br />instability on the backfilled area was observed. <br />
