These inspections were conducted roughly on a bi-weekly <br />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 appazent 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 aze cleaned out as <br />conditions warrant. <br />The following maintenance work was completed since the last quarterly report: <br />1. Part of the material was stockpiled for future spreading/drying/compacting when <br />conditions allow. <br />2. Part of the material was spread and compacted. <br />3. Refuse Area surfaces were conditioned for spreading refuse. <br />4. Maintained perimeter ditches. <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 40% complete on the toe of sub-azea 2-3 and 4. <br />The infill between these sub-areas is complete. The slopes appeared stable with some localized <br />erosion noted. <br />3607 County RD "65 <br />RanSely, CO 81648 <br />970-675-4300 <br />Fax 970-675-4399 <br />
