Northfield Partners, LLC <br />Northfield Exploration Project <br />BASELINE HYDROLOGY MONITORING PLAN -SUPPLEMENTAL INFORMATION <br />water at the Chandler air shaft. Further monitoring of the spring/seeps in Spring Creek <br />will continue as described above. <br />2. The proposed laboratory testing parameters for both groundwater and surface water <br />should include hardness. <br />Response: <br />Northfield has instructed its water analysis laboratory to report hardness on al] future <br />groundwater and surface water samples. <br />Completion diagrams for the three monitoring wells may be included with the baseline <br />hydrology monitoring information. If not submitted with the baseline information, said <br />diagrams will be required in the hydrologic monitoring section of the forthcoming permit <br />application package. <br />Response: <br />Northfield compiled preliminary monitoring well completion diagrams for the three referenced <br />monitoring wells; NF-Ol, NF-02, and NF-03. The well completion data is summarized in <br />Appendix A of this report. <br />4. Streamflow monitoring should be done during a peak flow event, rather than on a <br />specific day of a month. Flumes and/or staff gauges are not required for the baseline <br />monitoring due to the potential disturbance during installation. Documented streamflow <br />quantity may be estimated or measured by reasonable means. Pictures during monitoring <br />are beneficial. <br />Response: <br />Northfield agrees with the DMG comment to monitor stream flows during peak runoff events <br />rather than on an arbitrary monthly schedule. The monitoring is feasible since there aze personnel <br />prepazed to perform stream monitoring who live close to the monitoring points. No flumes or <br />staff gauges will be installed at this time. If flows occur, engineering estimates of the quantity <br />will be made in the field. <br />5. Describe the nature and water source far the two small ponds adjacent to Fawn Hollow <br />on the south edge of Highway 115. Does the natural drainage channel adjacent and <br />southwest of the ponds (running south to north) enter the ponds? <br />- 3 - 06/30/05 <br />
