Mr. Kent Gorham <br />April 25, 2011 <br />Page 5 <br />1/12/11). Please consider consolidating this information in one location in the permit <br />application. <br />NECC Response: The subsidence survey, mitigation and control plan information is <br />included in its entirety in Exhibit 24. Permit pages have been modified to reflect this <br />change. <br />15. Permit text narrative on page 2.05-90g states that structures are shown on Map 20 <br />Sheets 1-3 and Maps 11 and 12. Please indicate where a listing of all the structures and <br />renewable resources is located along with a brief description of each. [Rule <br />2.05.6(6)(a)(ii)] . <br />NECC Response: A listing of the structures shown on Map 20 Sheets 1-3 is included as <br />Exhibit 42. The listing of structures shown on Maps 11 and 12 are included in the permit as <br />Table 19. <br />16. With regard to mining proposed under TR-56, please state what structures, if any, will be <br />undermined and/or affected by subsidence. Permit text narrative should clearly indicate <br />with regard to TR-56 all surface structures and renewable resources that will be <br />undermined or be undermined and subsided. <br />NECC Response: Exhibit 42 includes a listing of structures shown on Map 20 Sheets 1- <br />3. No structures or renewable resource lands are planned to be undermined and subsided. <br />Structures and renewable resource lands planned to be undermined with development- <br />only works can be found in the details 44, 45, 46 and 47of Map 20 Sheet 3. The AVF <br />and renewable resource lands are shown on Map 20. The discussion is included on page <br />2.05-91. <br />16. Gas wells are indicated on Map 3, 2011 Mine Plan, according to annotation and the <br />legend provided. However, in the vicinity of mining, three gas wells are not shown; <br />26-09 south of Apache Seam mining, 25-14 south of the Apache Canyon Airshaft #1, and <br />25-08 northeast of the same airshaft. These wells are shown on Map 20, Sheet 1. It is <br />important that gas wells within and adjacent to the permit boundary be accurate as <br />compared to Map 20, for all maps that show gas wells. Please review and correct Map 3 <br />as necessary. <br />NECC Response: Map 3 has been corrected. The gas well names have been added to <br />Map 3. Locations of gas wells on Map 3 are verified to match those shown on Map 20 <br />Sheet 1. For detail specific to the gas wells in vicinity of mining in TR-56, see Figure 19 <br />(page 2.05-92). <br />17. Please correct the reference on page 2.04-11d to "Map 20, Sheets 1, 2, and 3" to correctly <br />reference the Map 6a series that show the structure contours for each coal seam. <br />NECC Response: Page 2.04-11d has been corrected to reference the appropriate map <br />series. <br />Agapito Associates, Inc.
