Positive drainage is established on <br />all areas. Vegetation is well established on previously reclaimed areas. <br />Observation of Fill Construction: (Description of material, compaction, lift thicknesses, slopes, <br />and construction methods). <br />No new fill was placed during the quarter. <br />Indications of Potential Failure or Instability: <br />None observed. Surface and side slopes were inspected for slumps, tension cracks, and other <br />indications of potential failure. <br />Threat to Human Life or Property: <br />None observed. Location and placement minimize potential impacts to life or property. <br />Page 1 of 2 <br />
