This was a complete inspection of the Yeast Mine conducted by Susan Burgmaier of CDRMS. No representative
of Seneca Coal Company was present during the inspection. Weather conditions at the site were sunny and dry at
the onset,but heavy rain set in on the afternoon of October 4th. No maintenance or reclamation activities were
observed during the inspection.

Ponds 011, 011A, 012A, 013 and 014 were holding water below the discharge level. Ponds O10 and 012
were discharging clear water. All pond embankments were stable and vegetated, and all spillways were stable and
unobstructed. There were small cracks on the crest of Pond 012,but they appeared to be surface desiccation
cracks that should not affect the stability of the embankment. The rip rap in the emergency spillway of Pond 012
was still covered in dirt for a crossing utilized while construction was underway in the area. The spillway was still
functional,but the rip rap should be restored in this section to prevent sedimentation offsite if water were
discharged through the spillway. ST-1 was dry.
Three new surge ponds were being constructed in the YPM 13 drainage of the North Pit,which drains into Pond
011A. One of the structures appeared to be completely excavated and the other two had been cleared of topsoil
