the minor flow at the Pond E discharge and at several downstream points
on Foidel Creek.
In compliance with applicable reporting requirements of both our CDPS
discharge permit and our Mining and Reclamation Permit, the
unanticipated discharge has been reported to the CHPHE-WQCD and
CDRMS.
Based on our field reconnaissance of the situation and discussions with
Environmental Staff and Dave Wallace, our next steps include; 1)
Reestablishment of runoff treatment capacity for Pond E; 2) Isolation,
dewatering, and clean-out of the coal fines in Pond E; and 3) Clean-up of
coal fines deposited in the proximate portion of Foidel Creek.
At present, we are consulting

In order to clean-up the coal fines deposited in the proximate portion of
Foidel Creek, we are currently evaluating the possibility of excavating one
or more small downstream catchment basins, placing silt fence at their
outlets to capture coal fines, and flushing the upper portion of the creek by
partially opening the discharge valve on Pond A. The catchment basin(s)
would be located where they would be readily accessible for clean-out.
