RE: March 14-15, 2011 Complete Coal Inspection Follow-up
Foidel Creek Mine (Permit No. C-1982-056)
Dear Mr. Nettleton,
During a complete coal inspection conducted at the Foidel Creek Mine on March 14th and 15th, 2011 it
was observed that road grading conducted on a portion of Haul Road A resulted in material being
pushed and deposited into the south side road ditch and being heaped at the inlet of the Pond B light-
use road. This caused the run-off of Haul Road A and the sediment that was initially directed down the
south side of the intersection of the of the haul road and the light-use road into a sump, and proceed to
Pond B, being instead diverted in an unapproved manner through a berm on the north side of the light-
use road, then down the north side of the haul road/light-use road intersection.
The unapproved flow caused sediment to be deposited into Foidel Creek, at the inlet of the Foidel
Creek culverts under Haul Road A, rather than the approved sump. It was observed that there was
water in Foidel Creek, however the flow was minimal.
Through discussions with TCC personnel, TCC restored the Haul Road A ditch, reconstructed the
drainage path as required, removed material from Foidel Creek and re-stored the berm along the Pond
B light-use road before the end of the inspection.
Based on the inspection report, an internal review, and the mitigating circumstances, the Division has
determined that the situation does not appear to have left the permit area, does not seem to have caused
contamination beyond the immediate footprint of the deposited material, and due to the situation being
remedied immediately; a Notice of Violation (NOV) is not needed at this time. The situation has been
documented in the March 15, 2011 inspection report.
Please note that such circumstances must be avoided in the future to ensure compliance. If a constant
problem persists an NOV may be required. Similar situations in the future and/or repeated
maintenance problems may result in NOV issuance.
