The Dewatering Evaluation provided by CGRS states that groundwater will <br />be pumped into unlined ponds east of the mine. However, the Mine Plan states <br />water will be pumped into the upland drainage seep and will flow to the Cache <br />La Poudre River. Please clarify this discrepancy. <br />As stated, in #3, above; discharge will utilize the Seep; consistent with the <br />approved discharge plan and permit. At the time C.G.R.S. was assessing the <br />discharge in its report, it was evaluating discharge through an option of entering <br />the discharge waters into the basin to the immediate east of the permit <br />boundary, where the existing Durham operation has an approved discharge <br />point. While C.G.R.S. verified that the Seep would not alter the evaluations made <br />in the report, the option to utilize the adjacent facilities is something the <br />operator would like to retain in the approved permit. <br />8. The Dewatering Evaluation provided by CGRS was carried out under the <br />assumption only one pit will be dewatered at a time. The Mine Plan provides for <br />simultaneous extraction of the pits by posting of additional warranty. Please <br />clarify if the Operator will only dewater one pit at a time. If the Operator <br />anticipates dewatering the cells concurrently, then the Dewatering Evaluation <br />must be revised to reflect this. <br />We believe this option is properly assessed by CGRS in their correspondence of <br />15 February 2011, included with this submittal. Please refer also to #10, below. <br />9. The Division is currently reviewing CGRS's Dewatering Evaluation and <br />additional comments will be forthcoming. <br />Varra Companies, Inc. correspondence of 23 February 2011 to the Colorado Office of Mined Land Reclamation 5 <br />(OMLR) in reply to OMLR correspondence of 4 October 2010 - Western Sugar Reclamation Land <br />Development Project- M-2010-049.
