GooloQy <br />The DMG's letter dated December 9, 1997 transmitted a list of questions from ARCO regarding <br />the slide and water dischazge situation at the Beaz No. 3 Mine. Following are Bear's responses <br />to ARCO's questions. Enclosed aze fourteen file folders which contain the information and data <br />requested by ARCO. <br />Please provide a detailed history of water outflows from the Edwazds Mine. Ho~v long <br />and at what times have you observed discharges? How lazge have these dischazges been? <br />Do they show variability? Have you sampled and analyzed water quality or made visual <br />observations about water quality? How have you managed this dischazge? Have you <br />treated the water prior to release and conducted monitoring? <br />Beaz -Bear has never noted an outflow from the Edwards Mine. The first outflow from <br />the area of the Edwazds Mine occurred on November 17, 1997. <br />2. Based on our site inspection on December 2, the Edwazds Mine outflow was conveyed <br />directly into the North Fork Gunnison River. I[ was our understanding, however, that this <br />water was to be first directed into the Beaz Mine sedimentation pond, rather than being <br />directly discharged to the North Fork. Please clazify this situation for us. <br />Beaz - Beaz's existing dischazge permit provides for the discharge of mine water directly <br />to the North Fork of the Gunnison River through Outfa11001. Therefore Bear was <br />prepazed to handle the mine water dischazge which emerged on November 17, 1997. <br />Have you conducted an evaluation of the water quality impacts to the North Fork posed <br />by this dischazge? What did you do and what does the investigation show? Have you <br />conducted biological or chemical monitoring to evaluate impacts? <br />
