ENERGY, INC. <br />a subsi~my el <br />~en7 c~neroaoe ~ <br />Twesmivion Cooper~ive <br />Dear Jim: <br />January 14, 2003 <br />Mr. Jim Stazk <br />Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />RECEIVED <br />1AN121 2003 <br />tlivisi°n °i AAinata4a and 6e°los" <br />RE: Professional Certification for the Coal Processing Waste Bank at the <br />Deserado Mine. <br />Permit No. C-1981-018 <br />During the fourth quarter of 2002, qualified persons working under my direction and I <br />conducted a series of compliance inspections on the active coal processing waste banks <br />located within the Deserado permit azea. These inspections were conducted roughly on a bi- <br />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 <br />of the refuse piles and to satisfy the requirements of Rule 4.10.2 of the Colorado Mined Land <br />Reclamation Boazd. <br />INSPECTION OF ACTIVE AREAS 2-3.4 and Sa <br />There are no apparent points of seepage, or indications of slope failure on the active piles. <br />The surface drainage facilities were adequately maintained and were working properly to <br />convey surface runoff. Sediment control structures need periodic maintenance and are <br />cleaned out as conditions warrant. <br />The following maintenance work was completed since the last quarterly report: <br />1. Spreading and compaction of refuse continued on Refuse Area 2/3/4. <br />2. Spreading and compaction of refuse continued on Refuse Area Sa. <br />3. A winter storage area was prepared on the south central end of Refuse Area Sa. <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 completion. The slopes appeazed stable with some <br />localized erosion noted. <br />3607 County RD #65 <br />Rangelg CO 81648 <br />970fi75-0300 <br />Fez 970b75-0399 <br />
