C- 2010 -089 PAR No. 2 New Horizon North Mine 9- Sep -2011 Page 8 of 25 13. Response accepted. 14. Response accepted. 15. Response accepted. 16. Response accepted. 17. Response accepted. Please also submit a copy of the surface rights and water augmentation plan to the Division for inclusion to the PAP when it is received. 2.04.7(2) — Surface Water Information 1. In Section 2.04.7 of the permit application, mention is made of Tuttle Draw and Coal Canyon in the regional surface water description and in the site specific surface water description. However, no mention is made until much later in the discussions of the two tributaries of Coal Canyon, namely Glasier Draw and Meehan Draw, and the tributary of Tuttle Draw, namely Nygren Draw, which pass through the permit area and which appear on Map 2.04.7 -1 and Map 2.05.3(3) -1. In order to avoid any confusion, please explain early on in the text descriptions that Glasier Draw and Meehan Draw are tributaries of Coal Canyon and that Nygren Draw is a tributary of Tuttle Draw. DRMS: The Division has no further concerns regarding this question. Revised descriptions appear on page 13 of Section 2.04.7 in the submittal dated May 26, 2011. However, the Division has additional questions concerning Section 2.04.7. a) In the section titled "Surface Water Monitoring" on pages 17 and 18 of Section 2.04.7, "Hydrology Description ", it is unclear in the discussion which surface water monitoring sites are to be included in the baseline monitoring program and whether they will continue to be monitored as part of the operational monitoring program. As an example, there is a discussion of monitoring sites SCC and NCC but it is not clear if they are part of the NHN baseline monitoring program since they do not appear in Tables 2.04.7 -5, 2.04.7 -6 or 2.04.7 -7. As another example, monitoring sites SW -N1, SW -N3, SW -N6, SW -N7 and NPDES 1 are mentioned as sites with historic data and are listed in Table 2.04.7 -5 under "Historical Reference Data ", but the text states that it is anticipated that these five sites will be monitored before disturbance. It is also not clear if "historical reference" in Table 2.04.7 -5 means baseline. Please revise the discussion and Table 2.04.7 -5, if necessary, to make it clear which sites are baseline monitoring sites, which sites are operational monitoring sites, and what "historical reference" means. b) On pages 17 and 18 of Section 2.04.7, "Hydrology Description ", there appear to be several typographic errors in the section titled "Surface Water Monitoring ". In the first paragraph, "nine 14" should be "14 ". In the same paragraph, it appears that SW -N11 should be SW -N211 and SW -N12 should be SW -N212. In the last paragraph of that section, it appears that SW -N13 should be SW -N213 and SW -N14 should be SW -N214. Please revise accordingly. 2. Response accepted. 3. Response accepted. 4.
