The DRMS forwarded your comment letter to the operator <br />and requested that CAM Mining LLC respond to your concerns and amend the application <br />accordingly. DOW's concerns focused on water quality impacts to East Salt Creek, and possible <br />hazards to wildlife associated with the proposed sediment pond. <br />The operator's response referenced revised Appendix N, which they state demonstrates that the water <br />quality of East Salt Creek will not be adversely impacted. Their response also addresses DOW <br />concerns with the sediment pond, and indicates that lining of the sediment pond is not warranted. <br />Further, the operator agrees to realign the BLM Drift Fence and the current design provides for a 5:1 <br />ramp on the east side of the sediment pond that could be used by wildlife as an escape. <br />We are requesting your review of the operator's response. The operator submitted a new Appendix N, <br />which describes probable hydrologic consequences to East Salt Creek. A copy of the revised <br />Appendix N is enclosed for your review along with the written response from CAM Mining LLC <br />(Item #52). <br />If you have questions or require additional information, please call me at 970-243-1571. <br />Sincerely, <br />Michael P.
