page 2.05-106.1 that TC will seek future approval to leave the passive water treatment <br />system and the 6MN Reservoir as permanent impoundments may remain in the text, but <br />please add that TC will reclaim these features until such a permit revision has been <br />approved by the Division. Addressed with 11/13/2018 submission <br />15. The North and South diversions must be removed and reclaimed in accordance with Rule <br />4.05.3(6). Please revise the reclamation plan to address reclamation of the north and south <br />diversion ditch. Addressed with 1111312018 submission <br />16. Based on your responses to the items above, please provide an updated reclamation cost <br />estimate for the reclamation of the passive water treatment system in accordance with Rule <br />2.05.4(2)(b). The current cost estimate approved for the Foidel Creek Mine already includes <br />the reclamation of the MIN Reservoir, so the estimate does not have to include a cost for the <br />reservoir. Once an updated reclamation plan has been agreed upon, the Division will conduct <br />a liability estimate. Not yet addressed. Please ensure all currently proposed items to be <br />reclaimed are included in an updated estimate. <br />Response: As part of their design work, CH2M Hill/Jacobs completed a preliminary cost estimate for the revised <br />design. The previously developed Reclamation Cost Estimate was updated with the acreages and volumes from <br />this preliminary cost estimate (include the Passive Treatment System and diversion ditches and the system outlet <br />ditch to the 6MN Reservoir). A copy of the updated Reclamation Cost Estimate accompanies these responses for <br />your reference and review. <br />17. Please submit a revised Map 29, Reclamation Plan Map depicting the post mine configuration <br />of the water treatment cells and the 6MN Reservoir. Not yet addressed <br />Response: Please see previous response to Comment 13. <br />18. In accordance with Rule 2.05.4(2)(h) on proposed revised page 2.05-122.1, please provide a <br />narrative that TC is seeking the approval of a new CDPS permit to discharge water from the <br />6MN reservoir and the discharge will not occur until this permit is in place. No longer <br />applicable to this revision as discharge is not being proposed. <br />19. Proposed revised page 2.05-131 cuts off the "Probable Hydrologic Consequences" section <br />heading and the first sentence of this section that is currently on page 2.05-131. Please revise <br />this page to include this information. Addressed with 1111312018 submission <br />20. Proposed revised page 2.05-145 does not include a portion of the paragraph from the <br />preceding page. Please review these pages and insure the text follows from the preceding <br />and subsequent pages. Addressed with 1111312018 submission <br />21. Proposed revised pages 2.05-145 to 146.1 appears to be missing information pertaining to the <br />Wolf Creek Reserve that was added with TR83. Please review the currently approved pages <br />and make the appropriate revisions to the most recent application pages. Addressed with <br />1111312018 submission <br />22. Proposed revised page 2.05-153 indicates that with the system, iron reduction at a maximum <br />design flow rate is estimated at 5901o. However, based on the C2HM Hill design submitted <br />with Exhibit 49EE indicates the iron reduction at the maximum designed flow of 357 gpm <br />will be 57%. Please revise the page to address this discrepancy. Addressed with 1111312018 <br />
