below the five foot trigger point you will need to notify the Division within 24 hours of <br />the occurrence, with a plan to mitigate the disturbance." <br />Applicant's Response: <br />The Applicant will provide the Division with ground water monitoring data as part of <br />the Annual Reclamation Report for the Bromley Lakes permit beginning with the 2010 <br />annual report. <br />If, during mining, ground water levels drop five (5) feet below the pre -mining baseline <br />levels the Applicant will notify the Division within 24 hours of said drop with a plan <br />to mitigate the impact. <br />16. "Item #26 states that a Nationwide Permit 46 will be obtained from the Army Corps <br />of Engineers to relocate the McCanne Ditch. Please commit to not disturbing the <br />McCanne Ditch and relocating it until the permit is obtained and a copy submitted <br />for the Divisions Files." <br />Applicant's Response: <br />The Applicant commits to not disturbing the McCanne Ditch until the necessary <br />permit is obtained from the U.S. Army Corps of Engineers and a copy of same is <br />submitted to the Division. <br />17. In regards to item #25, you state that the McCanne Ditch will serve to limit ground <br />water mounding, and that the slurry wall may enhance the flow of water in the <br />McCanne ditch. Given your mitigation plan for possible damages to the McCanne <br />ditch outlined in your response, the relocated ditch would be lined with bentonite. <br />This will hinder groundwater influx into the ditch after mining is complete, thus this <br />will not alleviate the mounding issues that may occur on the east side of the slurry <br />wall." <br />Applicant's Response: <br />The Applicant will not line the relocated McCanne Ditch with bentonite. <br />18. "The Division believes ground water mounding is a valid issue and a monitoring <br />plan is necessary. Ready Mix has four ground water monitoring wells in place to <br />monitor ground water elevations during the mining process. These wells need to <br />continue to be monitored until final bond release or the permittee can demonstrate to <br />the Division's satisfaction that the ground water regime east of the slurry wall has <br />not been impacted by its installation. It appears the closest structure to the proposed <br />slurry wall is located on the Spier property at the south east portion of the expansion <br />area. There are no monitoring wells between the proposed slurry wall and the <br />property, so it will be difficult to determine mounding impacts to this property. At <br />least two monitoring wells should be installed near the Spier property between the <br />10/2/2009 6 <br />
