New Elk Mine <br />Indications of Potential Failure or Instability: <br />None observed. <br />Threat to Human Life or Property: <br />None observed. Location and placement minimize potential impacts to life or property. <br />Potential Harm to Land, Air, and Water Resources: <br />None observed. Location of the waste bank minimizes potential impacts to land and water resources, <br />but failure could impact State Highway 12 and the Purgatoire River. <br />Maintenance Required: <br />The facility is in good early fall condition. <br />Supporting Documentation: (Compaction tests, surveys, photographs, field measurements). <br />Compaction testing was last done by New Elk Coal personnel in June 2015.
