The Division of Reclamation, Mining, and Safety has completed review of the 2008
Annual Hydrology Report (AHR) for the Southfield Mine. Please review our questions
or comments, if any, (highlighted in bold text) and respond, if necessary, within 30 days.
Monitoring Frequency - Surface Water
Exhibit 25 of the approved permit application details the hydrologic monitoring
frequency for surface and ground water at the site. Magpie Creek, Newlin Creek, and
Second Alkali Creek are monitored at the reclaimed mine site and Oak Creek is
monitored at the loadout. The required frequency is semi-annual visits with samples
taken semi-annually if flow is present. Visits were made to all required sites in May and
December during 2008. The only flow recorded during spring and fall visits was
recorded at the upstream and downstream sites on Oak Creek in late May. Water
samples were taken and sampled, although the sampling was not completed for the
constituents as required by Exhibit 25, part I (C) (5.) The operator has provided the
correct lab sampling information to the laboratory to ensure correct water testing for
future samples regarding dissolved and total species concentrations.
Monitoring Frequency - Sedimentation Pond Discharges
Four sediment ponds remain (two at the mine site and two at the loadout) to treat
surface runoff from the reclaimed areas. No discharge was recorded during 2008 from
any of these four ponds. This is consistent with Division inspection over the period.
Monitoring Frequency - Ground Water
Four ground water wells are monitored at the site on a semi-annual basis for both water
level and water quality. Two wells (MW-16 and MW-65) are completed in the Jack O
'Lantern coal seam and two wells (MW-23 and MW-NW) are completed in the Red
Arrow coal seam. These four wells were visited in May and December of 2008. MW-
