<br />time augme~ation will occur (ie: until mine areas 2 and 3 are fully backfilled to approved post-mining <br />topography, until pre-mining ground water levels aze observed, etc.). <br />Stipulation No. 5 <br />The division accepts the assumptions used in developing the slope stability analysis with the following conditions: <br />1. Develop a method to measure and report to the division how slopes are being maintained at a minimum of <br />2H:1V during mining. These values must be measured quarterly and submitted to the division with the <br />required annual report. If slopes aze detemrined at any time to be steeper than 2H:1 V, the division must <br />be notified immediately. Tn addition, DMG must be notified when mining is to occur within 200 feet <br />of any structure for which this or future stability analyses are provided. The office will then conduct <br />an inspection to verify that slopes are being mainained at 2H:1 V or flatter and to inspect the area above <br />cut slope for tension cracks or slumping. <br />2. If cracking or slumping is observed within the 25 foot buffer of any structure covered under a stability <br />analysis, mining must cease and the division must be notified immediately. <br />3 . If cracking or slumping is observed at anytime above any cut-slopes, the division must be notified and <br />the stability of the system must be re-evaluated prior to continued mining activities. <br />The amount of financial warra~y set by the Division for this operation is $317,000.00.
