Colorado 80222-1530 Re: Bear Coal Company CDPS Permit No. CO-0044377 Gunnison County Dear Mr. Kubic: The referenced discharge permit authorizes Bear Coal Company to discharge from two outfalls. Outfall 004 provides for the discharge from the sediment pond located at the Bear No. 3 mine site. Outfall 001 provides for mine water discharge. During November 1997, a slide occurred on the southwest corner of the Bear No. 3 Mine surface facilities. Shortly after the slide occurred, about 10 gallons per minute of water began flowing from the east slide scarp. Presumably the water is coming from the old B- Seam workings. The conductivity of the water is in excess of 6,000 umhoslcm which provides further evidence it is discharging from mine workings. The water flows through mud and slide debris prior to the point it can be contained in a pipe or pond. Bear plans to construct a treatment pond for this water to assure the suspended solids are settled before the water is discharged to the river. Since the location of the mine discharge has changed, the location of Outfall 001 will have to be moved about 1,000 feet downstream. The enclosed vicinity map shows the revised location of Outfall 001. Enclosed is a revised facility site sketch for the Bear No. 3 Mine which shows the location of the proposed treatment pond and outfalls 001 and 004. The treatment pond is sized as follows: Pond Surface Area 5800 SF Pond Depth 4 FT Pond Volume 0.109 MG
