Second Submittal <br /> 7.1.1 Monitoring Locations <br /> To facilitate monitoring groundwater immediately adjacent to the Site, LRM constructed <br /> 14 new monitoring wells on the Site properties in April 2017 under State Engineering <br /> Office approved monitoring well permits. Monitoring well locations are shown in Figure <br /> 3 and well construction permits are included in Appendix B. With the cooperation and <br /> permission of neighbors, LRM also intends to monitor the 24 neighbor wells. <br /> 7.1.2 Purpose of Monitoring Locations <br /> The proposed monitoring locations can be easily accessed by LRM to provide real-time <br /> groundwater elevgtion data. These monitoring locations are intended to provide baseline <br /> data representative of pre-mining groundwater levels for the area. It should be noted that <br /> the wells on neighboring properties have been pumped at a variety of times and rates and <br /> utilized for residential, agricultural, and commercial purposes over past years. The effects <br /> of this variation in pumping times, rates and water uses will be captured in any monitoring <br /> event. Once mining and pit dewatering commences,the monitoring locations will serve as <br /> indicators of dewatering irilpacts',and provide a base upon which model predicted impacts <br /> can be judged and updated. <br /> 7.1.3 Potential Impacts from Mining Operations <br /> As described previously, potential dewatering impacts are predicted to occur at five <br /> neighboring well locations during the mining operation. In two wells (Cherry and West), <br /> the drawdown is predicted to be significant enough to require mitigation. In the remaining <br /> wells, adequate saturated thickness is predicted that would allow continued production. <br /> If monitoring results show mounding in the areas that the model predicts are a potential for <br /> mounding and flooding of neighbors' properties occurs, LRM will take immediate action <br /> to determine the cause for the change. If it is in fact due to mounding, LMR could <br /> immediately pump from the perimeter drain to reduce the mound and find a long-term <br /> solution. Long-term solutions may be to increase drain capacity by adding another drain <br /> higher in the profile or implementing siphons from the perimeter drain. <br /> Loveland Ready-Mix Concrete 25 Telesto Solutions.Inc. <br /> ->o 1 sn 112_g...1 Imt.dy_2„fL A—t1al da January 2018 <br />
