MANAGEMENT May 31, 2003 J. J. Dudash Division of Minerals & Geology 1313 Sherman St., Room 215 Denver, CO 80203 RECEIVED JUN O Z 203 Re: Bowie No. 2 Mine Application for a Technical Revision Clarification Agent for Mine Water Permit C-96-083 Dear Mr. Dudash: Division of Minerals and CeolGgy On behalf of Bowie Resources Limited, enclosed is an application for a technical revision to provide for the use of a clarification agent to assure compliance with discharge permit requirements. The NALCO 7880 clarification agent is Aluminum based. The water which is treated with the clarification agent is discharged from Pond C. This clarified water flows into the Deer Trail Ditch and or the Fire Mountain Canal. Pages 2.04-38 and 2.04-39 were updated to include a discussion of mine inflows and the use of the clarification aid. The historical reference to other mines was originally incorporated into the permit as a basis for a projection of mine inflows into the Bowie No. 2 Mine. Since the Bowie No. 2 Mine has current mine inflow data, the historic reference to other mines in the area was deleted. Pages 2.05-73, 73i, 73ii and 74 were updated to evaluate the effect the clarification aid will have on the prevailing hydrologic balance. The following data are enclosed to support this technical revision application: 1. Amended pages 2.04-38 & 39, 2.05-73, 73i, 73ii and 74 2. Updated discharge permit 3. Material Safety Data Sheet for NALCO 7880 clarification agent. 4. Two pages from regulation no. 35 referenced above. The material safety data sheet should be filed in the permit with the updated discharge permit. The two pages from regulation no. 35 are provided for easy reference and are not intended to be incorporated into the permit.
