This may be demonstrated by locating and monitoring a well between the pit area and the Anderson's well prior to excavation. The static water level should be monitored quarterly during periods of operation. if the mining operation, as shown by the monitoring plan, does not significantly impact the groundwater system, the monitoring program may be discontinued through a Technical Revision. Response: Tn order to ensure that the portion of the proposed mine plan azea, which corresponds to mining yeazs 2007, 2008 and 2009, which is potentially hydrologically connected with the water bearing strata associated with the Anderson's water well, the Applicant will commit to establish a ground water monitoring well betwcen this mine pit area and the Anderson's water well. The enclosed "Map # 3, Tellier Gravel Pit -Mine Plan Map" shows that a proposed ground water monitoring well has been proposed in this azea. This site is labeled on this map as the "Proposed Ground Water Monitoring Well." The proposed parameters which will be analyzed and frequency of analysis aze contained in the discussion which was submitted to the DMG in our package dated 23 October 1998, specifically the revised information contained in Exhibit G, Water Information and the accompanying letter dated 9 December 1997 which was sent to the Anderson's Attorney and which was prepazed to address a specific stipulation promulgated relative to this project by the Routt County Regional Planning Commission. All of our proposals associated with the Routt County monitoring condition will be applied to the monitoring well proposed by the DMG. The results of this water monitoring information will be submitted to the DMG in connection with the required Annual Report for this operation. In the event that interim monitoring data shows dramatic declines in either water quality or quantity, then the DMG will be notified of these developments within seven workings days of this information becoming available. It is hoped that this additional information addresses all of the concerns raised in your letter, In the event that additional clarification is needed, please do not hesitate to call me at (970) 638- 4462.
