Jerry Nettleton, MCM Page 11 October 6, 2014 MCM provided updates to Table 56, Map 25 and the "Mine Facilities" discussion in Section 2.05.3 of the PAP to provide information to update the reclamation cost estimate for TR36/RN6. Their response to the Division's first adequacy review concerns is below. a) MCM Response: Table 56, Map 25, and the "Mine Facilities" discussion in Section 2.05.3 of the PAP have been reviewed, updated, and revised for consistency and to reflect the current disposition and status of all major mine structures and facilities. Copies of these revised materials are included with these responses. It is MCM's understanding that the Division will utilize this updated information to review and revise the reclamation cost estimate, and will provide the revised estimate for MCM's review. Once the updated reclamation cost estimate is finalized, a copy will be inserted in Exhibit 25. If the Division incorporates the relevant historical information from the current cost estimate in this update, it will replace the current cost estimate in Exhibit 25, otherwise, the current cost estimate will be retained as relevant historic background, and the updated cost estimate will be added to Exhibit 25. b) DRMS Response: The Division has reviewed the updated Table 56, Map 25 and the "Mine Facilities" discussion in Section 2.05.3 of the PAP and identified several issues that will need to be addressed. Please address the items below: i) Please depict and label all of the rock dust tanks on Map 25. This should include the rock dust tanks in the empire village, the two at the shop area and the one said to be located in the No. 5A Portal. ii) Either add more detail to Map 25 or create a separate map of the Coal Handling/Storage Facilities listed on proposed revised page 2.05 -9. Some items are identified on the revised map and others are not. Please clearly depict and label each of the items listed. iii) Please depict and label the No. 5 and 5a Mine Fresh Water System and its components (Two wells, water treatment system and No. 5 Mine Water Pump) on Map 25. iv) Please depict and label the Red Rock Crusher site on Map 25. v) Please depict and label all of the storage yards identified as "Ancillary Facilities ". vi) Please add the 100,000 gallon water tank to revised Table 56. c) MCM Response #2: The rock -dust tanks were not shown on Map 25 because they have now all been removed from the site. The referenced map and text were reviewed for consistency and revised as appropriate. Map 25 has been revised and updated to show the freshwater system components, and the Red Rock Crusher site. The "ancillary facilities" category is a "catch -all" which includes miscellaneous small areas associated with the other labeled mine facilities, involves very limited disturbance, all of which are included within the mapped mine disturbance areas. Therefore, it is not necessary or appropriate to separately identify and label these small areas. The 100,000- gallon tank has been added to Table 56. d) DRMS Response: i) Please include the 48 -inch Overland Conveyor to the bulleted list under the Coal Handling/Storage Facilities section of the permit on revised page 2.05 -9.
