ensure that any water discharged from the site will meet the current water quality standards. <br /> The permit number is COG 501574. <br /> Impacts to Groundwater/Hydrologic Balance <br /> Prowers Aggregate Operators, LLC. will monitor the groundwater levels surrounding the site <br /> and provide groundwater recharge if necessary via perimeter ditches/ponds. Prowers Aggregate <br /> Operators, LLC. will construct these ditches/ponds in the locations where direct discharge to an <br /> existing adjacent irrigation lateral or creek is not available to ensure that stabilized groundwater <br /> levels are maintained. They will discharge dewatering flows into existing adjacent irrigation <br /> laterals or ditches where possible to limit the disturbance to the surrounding land. <br /> To summarize the mitigation process, as each phase of mining/dewatering occurs a slurry wall <br /> will be constructed around it to limit offsite groundwater impacts from dewatering the pit. <br /> Prowers Aggregate Operators, LLC. will monitor the groundwater levels adjacent to mine as <br /> each phase progresses. If groundwater levels drop to a level that prevents an adjacent well from <br /> performing acceptably, according to that well's owner, Prowers Aggregate Operators will either <br /> implement a groundwater recharge ditch/pond near the well in order to raise the groundwater <br /> level in the vicinity of the well and hence return it's operation to acceptable standards, or will <br /> negotiate an agreement with that well owner to replace the well or provide replacement water <br /> via other means until the mining and reclamation activities are concluded. <br /> See the attached Monitoring Well Location Map which shows the locations of monitoring wells <br /> around the perimeter of the site that GP Aggregates, LLC. has installed in order to monitor <br /> groundwater levels. Additional monitoring wells will be installed around future phases prior to <br /> opening each phase in order to monitor the groundwater levels around that phase. <br /> -' JET Consulting,Inc.
