and fill slopes of the pad, have been vegetated for stabilization. Ground cover of living plants on
the approximate one-acre vegetated portion of the industrial area was found to be sufficient to
control erosion (there were no erosional features noted during the bond release inspection of
Apri121, 2005).
That the lands to which the release would be applicable are not contributing suspended solids to
streamflow or runoff outside the permit area in excess of premining levels, or in excess of levels
determined on adjacent nonmined areas, was demonstrated, and sediment ponds downstream of
the area were determined to be no longer required, on August 20, 2003 (Technical Revision
Number 41). No contribution to suspended solids to receiving streams was noted at the time of
the bond release inspection.
Based on the foregoing observations, the Division finds that the 3.3 acres of bond release area
meets the requirements for Phase II bond release.
Phase III Bond Release
The previous discussion of Phase I and II bond release indicates the gravel cover of the pad and
access road, and vegetative cover of living plants on roadway embankments and cut and fill
slopes of the pad, provides enough erosion control to satisfy the requirement of Section
4.15.10(2). The area was previously considered as a part of the approved (in 1998) industrial or
commercial post-mining land use (powerline), and such use had substantially commenced, and
was likely to be achieved (letter in Technical Revision 37 file dated January 5, 1998 from the
Division to P & M).
The Division conducted a bond release inspection on April 21, 2005. The inspection was
conducted in accordance with Section 3.03.2(2). The inspection focused on completion of
reclamation work, success of the work, erosional and slope stability of the reclaimed lands, and
implementation of the postmining land use. This evaluation considered, among other things, the
results of inspections and monitoring, the need for further reclamation work, and whether
pollution of surface or subsurface water is occurring, and the probability of future occurrence of
such pollution. The results of the evaluation of hydrologic impacts are summarized below. The
evaluation concluded that all reclamation has been completed in the bond release area, no water
pollution is occurring, and there is no potential for future water pollution. Field observations
support a finding to approve the bond release application.
The previous discussions of Phase I, II, and III bond release indicate that in all parts of the bond
release area, the permittee has completed all aspects of the reclamation plan.
Findin¢s with resard to Ground Water Impacts:
The Division conducted a detailed analysis of potential ground water impacts at the Edna Mine
in a review of the 2004 annual hydrology report.
Mining and reclamation operations in the bond release area are unlikely to have caused adverse
