Mr. Adams <br />Page 1 2 <br />June 1, 2011 <br />2. The Applicant is currently monitoring groundwater in 10 piezometers, several of which are <br />situated in the center of the pit. The Applicant has indicated that the 10 piezometers will <br />continue to be monitored, but the trigger point would not apply to all of them. Please indicate <br />which piezometers the trigger level will be applied to. <br />Typically the trigger point is based off of three consecutive months of variation from baseline <br />data. Please commit to notifying the Division in writing within 48 hours in the event any of <br />the monitoring wells exceed the lower baseline levels by 24 inches for three consecutive <br />months. In the event the trigger point is reached, the Division may require the Operator to <br />increase the frequency of groundwater monitoring. <br />4. The Applicant must have a mitigation plan for protection of wells in place prior to approval <br />of the Reclamation Permit. Please provide a mitigation plan to be implemented in the event <br />that the mining operation impacts adjacent wells users. Mitigation measures may include, but <br />are not limited to: <br />a) Provide a water tank and deliver water as necessary <br />b) Clean a well to improve efficiency <br />c) Replacing the impacted well with a new well <br />d) Providing groundwater injection/recharge to eliminate or reduce off-site impacts <br />5. The Applicant has been monitoring groundwater levels on a monthly basis, please commit to <br />continue to monitor at this frequency and to submit groundwater data with the Annual <br />Report. <br />6. The majority of the wells immediately south of the permit area have been completed in the <br />shallow alluvial aquifer. As such, there is minimal storage capacity to buffer the effects of <br />dewatering. At present there are no monitoring wells located on the southern permit <br />boundary. In order to monitor impacts to the wells, the Division believes additional <br />monitoring wells should be added to the southern permit boundary. Please respond. <br />As previously mentioned, if you are unable to provide satisfactory responses to any inadequacies <br />prior to June 16, 2011, it will be your responsibility to request an extension of time to allow <br />for continued review of this application. If there are still unresolved issues when the decision <br />date arrives and no extension has been requested, the application will be denied. <br />If you have any questions, please contact me at (303)866-3567 x8116. <br />Sincerely, <br />Michael A.
