February 11, 2005 <br />Coors Energy Company (CEC) <br />P. O. Box 467 <br />Golden, CO 80402 <br />Keenesburg Mine <br />Joint, complete, oversight inspection <br />February 10, 2005 <br />Participants: <br />Don MacDonald, CEC <br />Tom Kaldenbach, Colorado Division of Minerals and Geology (DMG) <br />Henry Austin, Office of Surface Mining (OSM) <br />I participated in the above inspection on February 10, 2005. The joint DMG/OSM Oversight Team <br />selected this mine for ajoint, complete oversight inspection during the 2005 evaluation year. Weather <br />conditions were mild and dry; and ground conditions were dry throughout the permit area with basically <br />no signs of recent surface water runoff. Inspection participants related that due to sandy soil types and <br />relatively flat topography throughout the permit and disturbed areas, surface water runoff has not been a <br />concern here throughout the life of this mine to date. <br />Mr. Kaldenbach and I began the inspection at DMG's offices with a review of permitting and <br />correspondence documents for the mine including: GIS overlays of the disturbed area air photo and the <br />permit area boundary. Information from Phase I bond release application SL-2 currently being processed <br />by DMG. June 30, 1997, correspondence from the Colorado Dept. of Public Health, Water Quality <br />Control Division (Division), documenting that coal mining has ceased at the mine (last coal removal was <br />1987), the NPDES permit for the mine expired June 30, 1997, and stating the Division's understanding <br />that discharges from the mine's approved point source discharge had ceased. (Inspection participants <br />and records reviewed also document that surface water runoff from disturbed areas of the permit are <br />fully contained on the permit area, and sediment pond 2 which is the primary sediment control pond has <br />not discharged since June 30, 1997.) The reclamation plan from the DMG permit was reviewed. The <br />most recent DMG Proposed Decision and Findings of Compliance Document, dated August 3Q, 2001, <br />was reviewed and a copy provided to OSM. The March 31, 2004, mid-term permit review for the mine <br />contains the most recent cost-estimate /bond calculation for the mine totaling $ 2,614,909. We <br />discussed surface and groundwater monitoring requirements for the mine. Mr. Kaldenbach discussed <br />receiving an adjacent landowner inquiry regarding ground water, as a result of the landowner being <br />notified of a Phase I bond release application (application SL-2) currently being processed by DMG. <br />Mr. Kaldenbach is corresponding with the landowner's representative regarding this inquiry. <br />Mr. Kaldenbach made introductions at the mine office and described our inspection protocol. I discussed <br />the OSM /DMG oversight relationship, described the joint OSM /DMG Oversight Team, and discussed <br />the 2005 Colorado Oversight Team Performance Agreement. Mr. Kaldenbach directed our field <br />inspection of the permitted and disturbed areas first, and then conduct a permitting and environmental <br />monitoring records review at the mine office. <br />
