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 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. 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. Stockpile spread and compacted. <br />2. General maintenance of drainage ditches. <br />3. Spread and compacted refuse. <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-azea 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 chazacteristics 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 />360'1 Cowry RD #65 <br />Rwgely, CO 81648 <br />970-675-4300 <br />Fu 970-675-4399 <br />
