Following discussions with Dan Mathews and Fred Banta, the following issues
for the Permit Revision are still outstanding,
The proposed loadout will need to be handled as a separate permit revision, in
order to allow a separate publication and public comment period, pursuant to
rule 2.08.4(3) and Section 115 (1)(c) of the Act. This is necessitated by the
fact that proper public notice of the proposed location of the facility has
not been provided.
Since MSHA has indicated that they do not consider the proposed underground
waste disposal plan to be approvable, we cannot recommend approval of the plan
in our proposed decision. A possible alternative would be to'modify the
temporary waste disposal plan to indicate that the disposal would be
constructed as a permanent facility. The capacity of the pile would have to
be demonstrated to be adequate for the proposed permit term. A11 requirements
of Rules 2.05.3(8) and 4.10 apply, including:
- diversions must be designed and constructed to convey the 100-year
runoff event from the pile itself and to convey upstream runoff away
from the pile;
- the pile must be constructed in compacted two-foot lifts and must be
inspected for stability each calendar quarter by a registered
Professional Engineer;
- NCEC must demonstrate that four feet of non-toxic cover is available
for reclamation of the pile, and final reclamation of the pile must be
fully addressed and accounted for in the reclamation cost estimate and
the reclamation bond.
