Cenewtion & <br />7Yansmissian Coopnafive <br />Deaz Jim: <br />Division of Minerals °nd Geulo9y <br />RE: Professional Certification for the Coal Processing Waste Bank at the <br />Deserado Mine. <br />Permit No. C-1981-018 <br />During the first quarter of 2004, qualified persons working under my direction and I conducted a <br />series of compliance inspections on the active coal processing waste banks located within the <br />Deserado permit area. These inspections were conducted roughly on a bi-weekly basis. <br />I am a professional engineer registered in the State of Colorado and my experience fulfills the <br />requirements of the Colorado Surface Coal Mining Reclamation Act. <br />The purpose of these inspections and subsequent certification is to ensure proper construction of <br />the refuse piles and to satisfy the requirements of Rule 4.10.2 of the Colorado Mined Land <br />Reclamation Board. <br />INSPECTION OF ACTIVE AREAS 2-3, 4 and Sa <br />There aze no apparent points of seepage, or indications of slope failure on the active piles. The <br />surface drainage facilities were adequately maintained and were working properly to convey <br />surface runoff. Sediment control structures need periodic maintenance and are cleaned out as <br />condi!ons warrant. <br />The :ollowing maintenance work was completed since the last quarterly report: <br />1. Continued stockpiling refuse material in SA. <br />2. Maintained side slopes of 2/3/4 and SA. <br />3. Prepazed pit surfaces to resume spreading and compaction. <br />Our permit requires no sub-drain system, as geotechnical investigations for the disposal site <br />revealed no groundwater present. <br />Permanent out slopes remain at approximately 90% complete on the toe of sub-area 2-3 and 4. <br />The infill between these sub-areas is complete. The slopes appeazed stable with some localized <br />erosion noted. <br />Refuse Area SA has progressed to the point where the drainage characteristics are starting to <br />evolve. The in-pit ditch on the west side is established with appropriate channel protection to <br />carry the projected runoff. <br />3607 County RD tt65 <br />Rangely, CO 81648 <br />970-675-0300 <br />Fnx 970-675-0399 <br />
