sampling includes collection of relatively undisturbed samples along 2 to 3 profile lines from the <br />crest extending into the impoundment. Selected samples will be tested to measure index <br />properties of the tailing. <br />• Evaluate the tailing beach and beach topography to verify the beach slope is consistent with that <br />envisioned in the original design. The beach area should be surveyed near the end of the first <br />spigot season. Evaluation of the differences with prior surveys should be performed on an annual <br />basis. <br />• Maintain the decant pond at least 500 feet from the crest under normal conditions. <br />• Implement weekly review of the data from currently installed piezometers during start-up. <br />Piezometric data review may be decreased to a monthly basis as deemed appropriate by the FOR <br />and based on weekly reading reviews. <br />• Install additional piezometers, as deemed necessary, along the crest and face of the dam to <br />evaluate the phreatic surface and changes resulting from tailing deposition. Frequency and <br />location of piezometer installation will be established during regularly scheduled inspection and <br />p iezometric data review. Initial piezometric data generated at start-up will be reviewed with <br />consideration to whether additional piezometers are required. <br />See and insert attached replacement pages 5 -1 and 5 -2, and ES -3, of stability report for updated text. <br />- Sec 6.4 Monthly monitoring inspections should not be entirely suspended in winter months, however, <br />DRMS realizes that certain allowances may need to be made for access /safety reasons or snow cover. <br />Conditions requiring exceptions to the normal inspection protocol should be well documented. <br />Response: Monthly visual monitoring inspections will not be entirely suspended in winter months but will <br />be completed as on -site conditions allow. Operators will also be performing daily monitoring activities as <br />part of deposition, regardless of the season. The operator inspections will also be limited by on -site <br />conditions and what can be safely accessed. Piezometer readings will also continue and if an alarm is <br />triggered a review of on -site conditions will occur, as appropriate. <br />Climax appreciates the Division's consideration of these responses and looks forward to receiving <br />approval of Technical Revision TR -20. Please feel free to contact me should you have any remaining <br />questions or comments. <br />Sincerely, <br />Raymond Lazuk <br />Environmental Manager <br />attachments <br />3 <br />
