N <br />• <br />3) CEC. states that some of the drillholes will be converted <br />into monitoring wells. Please specify which holes will <br />be converted into monitoring wells, or, if the decision <br />will be based on field observations during drilling, <br />specify the criteria which will be used in making this <br />determination? <br />4) What is the maximum number of monitoring wells that will <br />be installed? <br />5) Has CEC obtained well permits from the Colorado Division <br />of Water Resources for the proposed monitoring wells? <br />6) CEC states that some of the boreholes may be twinned if <br />geologic conditions dictate. Note that twinned boreholes <br />will increase the amount of bond required for reclaiming <br />the drillholes. In a telephone conversation between <br />Barbara Pavlik of the Division and Marcus Middleton of <br />CEC, it was agreed that the best way to address this <br />issue would be to bond for an additional SO boreholes in <br />the exploration permit to cover the possibility of <br />twinned boreholes. According to Mr. Middleton, the <br />twinned boreholes would be located within approximately <br />10 to 30 feet of the original borehole. It is assumed <br />that they would also be located within the same drill pad <br />as the original borehole; therefore an additional pad <br />would not be necessary. <br />7) CEC states that the minimum mud pit size will be <br />6'x3'x4'. What will be the maximum mud pit size? This <br />information is needed so that the Division can <br />conservatively estimate the bond required for reclamation <br />of the mud pits. <br />8) Please describe how CEC will comply with Rule 4.21.4(7) <br />to protect the hydrologic balance. <br />9) CEC states that topsoil will be stripped from the drill <br />pads only in the immediate vicinity of the drill rig, <br />boreholes and mud pits. The Division commends CEC on its <br />minimization of disturbance. However, a statement <br />regarding the management of drill cuttings should be <br />included in the NOI. Specifically, state how CEC will <br />keep the cuttings off the topsoil that is not stripped <br />from the drill pad in order to protect the topsoil <br />resource. <br />10) What is the maximum number of seismic holes that will be <br />installed? Note that right of access is also required <br />for the seismic transects. <br />11) CEC should revise its bond estimate to' reflect the <br />bonding of an additional l0 boreholes in the event that <br />twinning becomes necessary. The Division is currently in <br />
