RE: Bowie No. Mine Permit Revision No. 3 - Second
Geotechnic upplemental Response with Conditions
(Permit No: C-96-083)
I have reviewed Bowie Resources, Limited's (BRL's) second
supplemental response to my geotechnical adequacy comments fer it's
PR-03 permit revision application for facilities improvements at the
Bowie No. 2 mine site. The proposed facility upgrades include the
installation of a conveyor from the mine bench to a newly constructed
350,000 ton capacity coal storage pad with reclaim system and truck
loadout bin immediately adjacent to old State Highway 133. To make
room for this storage bench, BRL proposes to relocate Pond B down
slope from old State Highway 133. This relocation requires a 6.0
acre addition to the permit area. In addition, the entrance to the
property will be moved to the east. These modifications to the
surface facilities will theoretically allow the annual production of
the Bowie No. 2 mine to reach 5.0 million tons.
You will recall that I earlier accepted BRL's first round of
supplemental responses as demonstrating to my satisfaction that the
proposed facilities would be stable in both the operational and
reclaimed configurations, with two conditions.
(1) In the case of the transfer station excavation I requested that
the adjacent ditches be designed to preclude infiltration which
might deteriorate the cutslope's integrity. BRL has resolved
this concern by proposing to gunnite or concrete ditches C18 and
C19 to prevent infiltration.
(2) In each of the three instances, I also requested that BRL comply
with it's analyst's recommendations in field verifying that actual
