The current bond. amount of $393,000.00 is secured by
irrevocable letter of credit number 12632 which was issued by
the Central Bank of Grand Junction, Colorado. The obligation
for the letter is held by Central Bank National Association of
Denver, Colorado. This information was provided by DMG as a
result of this inspection. .The bond amount of $393,000.00 is
the same amount of bond which existed prior to the release of
the loadout which occurred some time. early in 1994.
Therefore, one must assume that although liability for the
loadout has been released, the bond amount was not reduced.
If this information is not correct, DMG must supply the
current bonding documents to OSM.
Another issue concerning the bond is the discharge which is
occurring from the F1 mine portal area. It is assumed at this
time that the discharge will be perpetual and will require
treatment due to the heavy concentrations of iron contained in
the water being discharged. If this is indeed the case,
further reduction of the bond will not be allowed. It is also
recommended that DMG review the bond amount based on the
treatment of the discharge and require-the permittee to'post
any additional bond which may be needed or in lieu of this
have
DMG should work with OSM in resolving
this issue.
