proposed operation and update the Exhibit 7K and permit text accordingly. Please use the same nomenclature when discussing the differentpowerlines. Please label the powerlines on the revised map 23. Response: - The revised and updated subsidence evaluation and associated text revisions provided as a supplemental submittal on March 19, 2015 address this Comment. 21. Revised page 2.05-184.11 indicates a copy of the existing subsidence agreement with the powerline operators has been forwarded to the Division. The agreements the Division has on file in Exhibit 7 -Dl are from 1995 and 1996 Please provide updated letters from the owners of the powerlines that might be impacted that state that the owners of the powerlines are aware of the potential impacts and of the proposed mitigation/repair measures proposed for mining in the WCR. Response: - The one powerline (Yampa Valley Electric) which will potentially be affected by the activities proposed under PR10 is covered by an existing easement agreement which allows for undermining and subsidence of the line. A copy of the agreement is provided with these responses for insertion in Exhibit 2. 22. According to the table of contents for the Exhibit 7K, there are 15 total drawings included with the evaluation. Exhibit 7K only included drawings 1 to 4. Please ensure all of the drawings, tables and figures are included when the revised subsidence evaluation exhibit is submitted. Response: - The revised and updated subsidence evaluation and associated text revisions provided as a supplemental submittal on March 19, 2015 address this Comment. 23. Revised page 2.05-181.11 indicates pasturelands overlie the WCR. Pasturelands fall under the definition of renewable resource lands in accordance with Rule 1.04(111). Please revise this section of the permit to include a description of the worst possible consequences that subsidence will have on this renewable resource land in accordance with Rule 2.05.6(6)(b) and if necessary a monitoring plan, subsidence survey and subsidence control plan. Response: - The referenced text discussion has been expanded to describe potential subsidence -related impacts to those areas of pastureland which overlie the proposed Wolf Creek mining area. As noted, subsidence effects will be negligible relative to the pastureland use, so monitoring, surveys, and subsidence control plans are not applicable or relevant. 24. Revised page 2.05-184.10 does not follow the text preceding it on the currently approved page 2.05-184.9. Revised page 2.05-184-.10 appears to begin with information regarding the Fish Creek and Associated AVF on the previous section of the permit. This page also omits or deletes a paragraph under a section titled Stock Ponds and Surface Water Monitoring Sites on the currently approved page 2.05-184.9. Please review this proposed revised page and adjust it to follow the text from the currently approved page 2.05-184.9. Response: - The referenced page and text section have been reviewed and revised to address the noted concern with text continuity. Revised copies of the corresponding pages accompany these responses for replacement in the PAP. 25. Rule 2.05.6(6) (c) (ii) requires that the application shall include an appropriate map, prepared according to the standards of section 2.10, showing the location of monuments to be installed and structures to be monitored within the permit and adjacent area. Revised pages 2.05-191.8 and 191.9 indicate that TC will monitor monuments along RCR33 and the Railroad. The Division could not locate a map in the permit that depicts the monuments/subsidence reference points used to monitor subsidence related impacts to these structures. Please submit a map that complies with the cited rule. Response: - Revisions and updates to the accompanying Map 23WC include delineation of those areas where subsidence monitoring points will be established to monitor subsidence of RCR33, the UP Railroad Spur, and the YVEA Powerline.
