These inspections were conducted roughly on a bi-weekly basis. <br />1 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 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 continued maintenance and will be cleaned out <br />as conditions warrant. <br />The following maintenance work was completed since the last quarterly report: <br />I. Erosion controls along ditches and slope imprinting were maintained on sub-areas 2/3 <br />and 4. <br />2. Spreading and compaction of refuse on sub-areas 2/3 and 4. <br />3. Cleaning and enlargement of Pond 2/3. <br />ti ~, <br />Sub-area Sa has not beeri'actively worked and or compacted during this quarter. <br />Our permit requires no stib-drain system, as geotechnical investigations for the disposal site <br />revealed no groundwater present. <br />Permanent out slopes remain at approximately 85% complete on [he toe of sub-area 2-3 and <br />approximately 55% complete on the toe of sub-area 4. These slopes appeared stable. Pit 5 <br />consists of a thin layer of refuse over the entire area. <br />The groundwater monitoring well installed behveen sub-areas 1 and 2-3 has remained dry to date. <br />
