SUBJECT: Bowie No. 2 Mine, Permit No. C-96-083, 1998 Annual Hydrology Report
I have completed my review of the 1998 Annual Hydrology Report (AHR) and Mine Inflow Report
for the Bowie No. 2 Mine. The 1998 AHR is well organized and is a high quality document.
The baseline data is presented concisely in the pemtit document. I reviewed the baseline data in the
permit, and compared it to 1998 surface water and groundwater sample results. I agree with Bowie
Resource Limited's (BBC's) conclusion that the 1998 sampling season provides results consistent
with baseline information provided in the permit application. No significant anomalies were noted
with the water quality data presented.
With just a few exceptions, the frequency of data collection was in compliance with the approved
monitoring plan. Overall, the operator did a good job at collecting and reporting the required
monitoring data. Deviations from the approved monitoring plan are discussed in the comments
below.
Mine inflow information was reported for 1998. There was no measurable mine water inflow
during 1998, and the mine has not discharged any water from the underground workings. The Mine
Inflow Report is acceptable as submitted.
I have the following specific comments regarding [he 1998 AHR:
L BRL states that no samples were collected from the small area exemptions (SAES) located
within the permit area. Page 2.05-32 of the permit states that BRL will monitor the flow from the
SAES to assure compliance with Rule 4.052(3), and the applicant will use its best efforts to obtain
samples. With the exception of the pump station located near Deer Trail Ditch, BRL provides no
explanation for the lack of sampling at the SAE locations. Please explain why samples were not
collected from the SAE areas. If appropriate, provide revised page(s).
