STATE OF COLORADO <br />DIVISION OF MINERALS AND GEOLOGY <br />Department of Natural Resources <br />1313 Sherman S[., Room 215 <br />Denver, Colorado 80203 <br />Phone: (303) 866-3567 <br />FAX: (303j 832106 <br />July 30, 2003 <br />Mr. Jerry Nettleton <br />Montgomery Watson Harza <br />P.O. Box 774018 <br />Steamboat Springs, Colorado 80477 <br />Re: Kerr Coal Company -Man Mine (Perniit No. C-80-006), 2002 Annual <br />Hydrology Report and Annual Reclamation Report Review <br />Deaz Mr. Nettleton: <br />COLORADO <br />DIVISION O F <br />MINERALS <br />GEOLOGY <br />0.EC LAMATION•MINING <br />SAFETY•SCIENCF <br />gm Owens <br />Governor <br />Greg E. Walther <br />Executive Direttor <br />RonaM W. Cattany <br />Division DireROr <br />Natural Resource Trustee <br />The Division has reviewed Kerr Coal Company's 2002 Annual Hydrology Report (AHR) <br />and Annual Reclamation Report (ARR) for the Marr Mine. Both reports aze acceptable <br />as submitted. <br />The 2002 AHR was well organized and EFCI did a good job at collecting and reporting <br />the required monitoring data. The frequency of data collection for surface water and <br />groundwater is generally incompliance with the approved monitoring plan contained in <br />the permit document. With only one minor exception, EFCI obtained all required water <br />level measurements and samples for laboratory analysis from groundwater monitoring <br />locations. It appears that one quarterly sample was not collected and reported for Well <br />AP-1 in April 2002. It was also noted that Wells 79-3 and SP-Ol aze not shown on the <br />Mine Area Monitoring Stations Map contained in the 2002 AHR. There were no <br />recorded dischazges from any of the sediment ponds during the 2002 water year. <br />The major reclamation activity at the Marc Mine during 2002 was the plugging and <br />sealing of old exploration holes and alluvial monitoring wells at the site. All plugging <br />and abandonment work was successfully completed in October 2002. No backfilling or <br />re-grading was conducted in 2002. Two small azeas were interseeded during 2002 to <br />enhance vegetative growth. <br />The Division has no further comments regarding the 2002 AHR and 2002 ARR. If you <br />have any questions concerning the Division's review, please contact me. <br />Sincerely, <br />M:cc~uQ P13o1 <br />Michael P. Boulay U <br />Environmental Protection Specialist <br />cc: Sandy Brown <br />Office of <br />Mined Land Reclamation <br />Office of <br />Active and Inactive Mines <br />Colorado <br />Geological Survey <br />
