RE: 2009 1" Quarter Report Review, Southfield Mine, Permit No. C-81-014
Dear Mr. Patterson:
The Division of Reclamation, Mining, and Safety has completed review of the 1St quarter
reporting submitted for the sediment ponds, discharge monitoring reports, and waste pile at the
Southfield Mine, #C-81-014. Please consider our comments noted in bold text and highlighted
and make any necessary changes or adjustments in future reporting to the Division.
Discharge Monitoring Reports (DMR) - The DMR's submitted and reviewed reflect observations
consistent with Division monthly inspections during the quarter. No discharge from any of the
four sediment ponds was recorded and/or sampled.
Sediment Ponds Inspections- The inspection reports demonstrate compliance with Rule
4.05.9(17) for impoundments, which requires quarterly inspection of each impoundment by a
qualified professional specialist under the direction of a registered professional engineer. For
future reports, please correct the heading for the "Quarterly Sedimentation Pond
Inspection Report" to reflect compliance with Rule 4.05.9(17) rather than 4.05.6(17). Two
sediment ponds are located at the reclaimed main facility site and two ponds are located at the
reclaimed loadout. No discharge was recorded at any of the ponds during the quarter.
Observations are consistent with field observations noted during Division inspections during the
period.
Waste Pile Inspections - The report submitted and reviewed meets the requirements under
Rules 4.09.1(11) and 4.10.2(2). Nothing of concern was noted.
We have no further questions or comments at this time. If you have questions, please call me.
Sincer ly,
Gorham
