The Colorado Division of Minerals and Geology (Division) has finished its adequacy review of
Bowie Resources LLC (BRL) responses, dated June 9, 2005, for Technical Revision No. 37 (TR-
37) for the Bowie No. 2 Mine. The following is the status of these issues:
The Division requested revised hydrology designs for the emergency spillway for Pond F.
The Division has no further concerns. In the submittal dated June 9, 2005, BRL provided
revised Figures 3 and 4 and revisecf hydrology design pages App-B-S and App-B-6 for the
emergency spillway.
As mentioned in item number 5 below, BRL also submitted hydrology design information
for the channel structures that will take pond F emergency discharge flow over the Fire
Mountain Canal. The Division has determined that its jurisdiction ends with the
emergency spillway at the base of the pond F embankment and does not include the
remaining channel structures.
2. Please provide a revised page 2.05'-30 that contains a brief description of the primary
and emergency discharge systems for Pond F.
The Division has no further concerns. In the submittal dated June 9, 2005, BRL provided
a revised page 2.05-30.
Please show a depiction of the buried primary discharge pipe for Pond F on Figure 3,
Pond F Detail.
The Division has no further concerns. Figure 3 was revised accordingly in the submittal
dated June 9, 2005.
