Re: Bowie Resources, LLC, Bowie No. 2 Mine
Permit Revision No. 10, Northern Extension of B-Seam Mine Plan
Adequacy Response
Permit C-1996-083
Dear Mr. Dudash:
The DRMS' letter dated June 6, 2007 transmitted its adequacy response for the
referenced permit revision. By letter dated January 30, 2008, BRL provided a partial
response to the DRMS' comments and concerns. On behalf of Bowie Resources, LLC,
following are its responses to the DRMS' comments and concern.
1. No response required.
2. Additional down gradient monitoring wells and points of compliance are the
subject of this item. Down gradient monitoring wells are technically difficult to
implement because of the extreme depth required to establish such wells. In
addition, it may be technologically impractical to establish a representative
monitoring well within the site's highly fractured and faulted geological
system. Additional down gradient monitoring wells as currently required are
economically unreasonable. The cost to permit, design, drill, complete, and
develop a single ground water monitoring-well at a depth of 2,000 feet or
greater could be in excess of $200,000 per well. In 2007 $1,000,600 was
spent on two exploration drill holes that were drilled to a depth of 2,500 feet.
The cost to install multiple ground water monitoring wells will be in excess of
$1,000,000. (R Squared Incorporated, January 2008) Bowie will attempt to
install two additional down gradient groundwater monitoring wells during 2009
with the understanding that the completion of functioning monitoring wells
may not be technologically practicable. The proposed wells (DH-68) are
located on Iron Point as shown on Map 9. The wells will be completed in the
B-Seam and in a water bearing zone above the B-Seam.
BRL intends to have the local groundwater reclassified by the CDPH &E to
limited use and quality so point of compliance monitoring wells should not be
required.
