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 />requvements 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 are 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 />conditions warrant. <br />The following maintenance work was completed since the last quarterly report: <br />1. Slope imprinting was maintained on sub-area 2/3-4. <br />2. Spreading and compaction of refuse on combined sub-areas 2/3 and 4. <br />3. Minor regrading and compaction of portions of sub-area 5. <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 85% complete on the toe of sub-area 2-3 and <br />approximately 80% complete on the toe of sub-area 4. The infill between these sub-areas is <br />complete. The slopes appeared stable. Pit 5 consists of a thin layer of refuse over the entire area. <br />To date, a total of 4,353,891 tons of refuse have been placed in the 2/3/4 combined sub-area and a <br />total of 417,829 tons of refuse have been placed in sub-area ~a.
