• • <br />DEPARTMENT OF NATURAL RESOURCES <br />David H. Getche5, Executive Director <br />Richard D. Lamm <br />Governor <br />Mr. Larry Reschke <br />Blue Ribbon Coal Co. <br />P.O. Box 58 <br />Delta, CO 81416 <br />June 10, 1985 <br />RE: Technical Revision Stipulation No. 2, File No. C-047-81 <br />Dear Mr. Reschke: <br />III IIIIIIIIIIIIIIII <br />999 <br />The Division has completed it's review of your submittal dated April 30, 1985. <br />The quantity, location and standard construction detailed for the eight survey <br />monuments and three piezometers are all acceptable. We agreed during our <br />telephone conversation May 31, 1985, that the steel casing proposed for the <br />piezometers is not necessary and can be deleted. <br />You have proposed, in your submittal, that the survey monuments be monitored <br />for movement "quarterly for the first year and annually in June for the next <br />two years". Due to the history of stability problems at the mine bench and <br />the fact that the bench is now a permanent underground development waste <br />disposal structure, this proposal is not sufficient. We require that the <br />bench be monitored quarterly for a minimum of three years. At that time, if <br />insignificant movement has occurred, in the opinion of the Division, <br />suspension of monitoring may be requested. Quarterly monitoring shall <br />continue until cessation has been approved, in writing, by the Division. <br />The proposed frequency of water level and water quality monitoring is <br />acceptable. However, the plan proposes to cease water level monitoring after <br />three years and makes no statement regarding water quality testing duration. <br />In both cases, as above, monitoring shall continue until cessation has been <br />approved, in writing, by the Division. <br />Finally, in the cases of survey monitoring and water level monitoring, no <br />statement is made regarding submission of the monitoring results. In each <br />case, the results shall be submitted within two weeks following completion of <br />the periodic monitoring. <br />With the addition of these few changes, the bench monitoring plan is <br />acceptable. <br />Please feel free to call if you have any questions. <br />Sincerely, <br />Susan Mowry <br />Reclamation Specialist ~ <br />MINED LAND RECLAMATION DIVISION <br />DAVID C. SHELTON, Director <br />SM/sjv <br />14~34Gentennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel. (303) 866-3567 <br />
