With a few minor exceptions, the proposal is <br />acceptable. As we discussed earlier this morning, Colowyo needs to address the following <br />concerns prior to Division approval of the revision. <br />1. The reclamation cost estimate for reclaiming the drill access roads does not appear [o <br />include regrading costs. Please estimate the costs that would be incurred, and adjust the <br />liability figure accordingly. <br />2. The total additional bond amount, as stated in the Technical Revision 28 "Bond <br />Calculation Add-On" summary does not appear to include indirect costs. The current <br />percentage of indirect costs associated with the entire mine reclamation estimate is 17.29 <br />percent. Please include an additional ]7.29 percent of the total bond amount for indirect <br />costs. <br />3. We discussed the Division's concern with the location of [he drill hole access ro:lds in <br />relation to known areas of instability. You indicated that the roads would be above those <br />areas, and should not cause concern. No further response on this matter is necesstlry. <br />Should you or your staff have questions or need additional information regarding these concerns, <br />please contact me. <br />Sincerely, <br />/L~ ' <br />Susan L Burgt ier <br />Environmental Protection Specialist <br />SLB\051794.
