Box 483 Paonia, Colorado 81428 RE: Adequacy Review, 2000 Annual Reports, Bowie No. 2 Mine, Permit No. C-96-083, Bowie Resources Limited Dear Mr. Beaz: ®~ D I V 1 5 1 0 N O MINERAL: GEOLOG` REC LA MATIOf MINING•SAFETI Bill Owens Governor Greg E. Walther Executive Director Michael B. long Division Director The Division has finished its review of the 2000 Annual Report submitted by Bowie Resources Limited (BRL). This letter is divided into three sections that correspond with the three sections of the annual report. 2000 Annual Hvdroloev Report The Division agrees with BRL's assessment that the data does not show that there have been any negative impacts to water quality and water quantity due to mining activities at the Bowie No. 2 Mine. This conclusion is based on a review of hydrologic data from surface water and ground water monitoring stations. The surface water monitoring sites include ponds, streams, the North Fork of the Gunnison River, irrigation canals and springs. The ground water monitoring sites include drill holes and alluvial wells. The Division appreciates the modifications that BRL made to the presentation format for the hydrologic tables. Having minimum, maximum and average values for the baseline data and for the operational period data in each table helps in the analyses of the data. Also, using the "<MDL" symbol (less than minimum detection limit) avoids confusion as to whether or not a chemical parameter was tested. BRL also provided responses to the Division's adequacy review letter for the 1999 Annual Hydrology Report (AHR). The Division agrees with BRL's responses and has no further concerns.
