Waiting for outcome of groundwater modeling study to determine <br />reimbursement for pump <br />Case well -contacted AI mid May <br />11. Waiting for outcome of groundwater modeling study to determine <br />reimbursement or payment of new well and pump <br />12. Stated to Mr. Case, that if the situation worsened that AI could provide <br />assistance during the interim period <br />In addition to the above, the Platte Valley Mine ceased dischazge from one dewatering <br />pump, in early April, into the South Platte River. As stated in our mitigation efforts, this <br />water is pumped into the ski lake located east of the plant. The second discharge point <br />into the river will cease shortly and water will be pumped water into an old, abandoned, <br />unlined channel of the McHannon Ditch. This will allow water to recharge the area north <br />of the mine. If during the course of the water modeling study shows no impact to the <br />area to the north, water to this area will cease and discharge to the river may resume. <br />To date, Joe Sasaki, who sent the Division a letter, has not contacted Aggregate <br />Industries about issues with his wells. Aggregate Industries is concerned that because we <br />are offering to pay for the deepening of certain wells that many more landowners in the <br />vicinity of the mine will come forward with unwarranted complaints of injury to wells. <br />We recognize the severity of the drought and its impact in the area and sympathize with <br />the landowners affected by these conditions. At this time, AI feels it is necessary to <br />complete a groundwater modeling study to determine future obligations to adjacent <br />landowners and prevent unwarranted claims against Aggregate Industries. The <br />groundwater study will take approximately 4-6 weeks for completion. <br />We hope this provides the Division with the course of action AI has chosen to take. <br />Please call me at 303-716-5304 if I can provide additional information. Thank you. <br />Sincerely, <br />Jamie W. Gaboriau <br />Manager of Environmental Affairs <br />attachment <br />
