PERMIT #: M- 2004 -031 <br />INSPECTOR'S INITIALS: DB2 <br />INSPECTION DATE: 05 October 2011 <br />report by Environment, Inc. (attached) corroborates this conclusion. The Bull Seep is able to convey some of <br />the ponded water around the Hazeltine pit, but the current configuration of the seep does not allow it to drain <br />the upgradient ground and maintain historical ground water elevations in the same manner that a deeper <br />feature such as a French Drain might. <br />It is the determination of the Division that, in order to relieve the ground water mounding situation, the <br />operator must provide a means of ground water conveyance around the pit, outside of the slurry wall, that <br />will maintain the ground water table at a level that will prevent water table rises and saturation / inundation <br />of the upgradient land. The operator has more than one option available with which to achieve this. The <br />most effective option, with perhaps the highest probability of long -term success, is to install a French Drain <br />around the eastern perimeter of the slurry wall. Alternatively, the operator can deepen and /or widen the Bull <br />Seep to allow it capture ground water at greater depth than it is currently. The operator must submit a plan <br />to the Division within 60 days of this report. Installation of the chosen option must be completed within 90 <br />days of final Division approval of the plan. <br />Another problem that was observed on the Hazeltine site is an infestation of weeds. The operator is advised <br />that weed control measures must be implemented in time to prevent a re- emergence of this infestation in the <br />Spring of 2012. The Division will check the success of the weed control program in the Spring of 2012. <br />Page 3 of 18 <br />
