COMMENTS
This was a partial inspection of the Seneca IIW Mine conducted by Susan Burgmaier of DRMS. Dennis Bugay of
Seneca Coal Company was present during the inspection. Weather conditions were clear and dry at the time of the
inspection. The area has been in a dry weather pattern the last few weeks, enabling the operator to complete many
of the scheduled reclamation and maintenance projects on site.

Straw wattles were in place on all newly reclaimed road sections that are not within the sediment control
system. The wattles were installed in overlapping sections to ensure that all sediment would be retained within the
disturbance area.
Ponds 006 and 016 both held water. The embankment of Pond 016A had been breached in accordance with the
approved slide remediation plan(TR 73), and was nearly drained. The spoil spring above Pond 016A has been
redirected southward in a channel along Road J so that it enters Pond 016 on the south side. The spring continued
to flow at approximately 100-125 gpm.
Seeps and springs throughout the mine area have yet to dry out. The newly installed toe drains along the MEHR
and at the oil well slide and Pond 006 were all flowing.
