Twentymile Coal, LLC. <br />Page 5 <br />April 3, 2015 <br />permit text accordingly. Please use the same nomenclature when discussing the different <br />powerlines. Please label the powerlines on the revised map 23. <br />21. Revised page 2.05- 184.11 indicates a copy of the existing subsidence agreement with the <br />powerline operators has been forwarded to the Division. The agreements the Division has on file <br />in Exhibit 7 -D 1 are from 1995 and 1996. Please provide updated letters from the owners of the <br />powerlines that might be impacted that state that the owners of the powerlines are aware of the <br />potential impacts and of the proposed mitigation /repair measures proposed for mining in the <br />WCR. <br />22. According to the table of contents for the Exhibit 7K, there are 15 total drawings included with <br />the evaluation. Exhibit 7K only included drawings 1 to 4. Please ensure all of the drawings, <br />tables and figures are included when the revised subsidence evaluation exhibit is submitted. <br />23. Revised page 2.05- 181.11 indicates pasturelands overlie the WCR. Pasturelands fall under the <br />defmition of renewable resource lands in accordance with Rule 1.04(111). Please revise this <br />section of the permit to include a description of the worst possible consequences that subsidence <br />will have on this renewable resource land in accordance with Rule 2.05.6(6)(b) and if necessary a <br />monitoring plan, subsidence survey and subsidence control plan. <br />24. Revised page 2.05- 184.10 does not follow the text preceding it on the currently approved page <br />2.05- 184.9. Revised page 2.05 - 184 -.10 appears to begin with information regarding the Fish <br />Creek and Associated AVF on the previous section of the permit. This page also omits or deletes <br />a paragraph under a section titled Stock Ponds and Surface Water Monitoring Sites on the <br />currently approved page 2.05- 184.9. Please review this proposed revised page and adjust it to <br />follow the text from the currently approved page 2.05- 184.9. <br />25. Rule 2.05.6(6)(c)(ii) requires that the application shall include an appropriate map, prepared <br />according to the standards of section 2. 10, showing the location of monuments to be installed and <br />structures to be monitored within the permit and adjacent area. Revised pages 2.05 -191.8 and <br />191.9 indicate that TC will monitor monuments along RCR33 and the Railroad. The Division <br />could not locate a map in the permit that depicts the monuments /subsidence reference points used <br />to monitor subsidence related impacts to these structures. Please submit a map that complies with <br />the cited rule. <br />26. On revised page 2.05 - 191.8, the applicant indicates subsidence monitoring of RCR 33 and 27 will <br />be conducted quarterly while active longwall mining is occurring. Please clarify; does TC intend <br />to monitor both these roads the entire time active longwall mining is occurring in the WCR? Or, <br />will monitoring be initiated when the longwall operation is within a specific distance to these <br />structures? If so, please indicate this distance. <br />
