III IIIIIIIIIIiiilll <br />999 <br />STATE OF COLORADO <br />Roy Romer, Gove <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED A. BANTA, Director <br />August 22, 1988 <br />Ms. Linda Limbach <br />Eastside Coal Company, Inc. <br />P.O. Box 161 <br />Siel, CO 81652 <br />Re: Permit No. C-84-063, Subsidence Survey for 1988 <br />Dear Ms. Limbach: <br />Enclosed is Dr. Pendleton's comments on your 1988 subsidence survey. He makes <br />two major points in his review. One is a need to have the accuracy limit <br />calculated for the second order survey and incorporated in the report. This <br />should be done for the 1989 subsidence survey. His other point addresses the <br />possibility of Monument No. 2 falling within the angle-of-draw in the next <br />years mine plan. Eastside needs to take care that this does not occur prior <br />to collecting baseline elevation on this monument. <br />In summary, the accuracy limits should be included in the 1989 survey. No <br />revision is needed to the permit to include this. Survey of Monument No. 2 <br />needs to occur prior to any possibility of the underground workings <br />approaching the angle-of-draw for this monument. Therefore, it may be more <br />prudent to survey Monument No. 2 in the 1989 subsidence survey. <br />If you have any questions please call. <br />Sincerely, <br />~~- ~~~ <br />Candace M. Thompson <br />Hydrologist <br />CMT/ljt <br />Enclosure(s) <br />9674E <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel. (303) 866-3567 <br />
