Concentrations are no longer representative of the current mine plan and should be updated. (Rule 2.04.7(1) (a)(i), requiring the applicant to provide the depth below the surface and the horizontal extent of the potentiometric surface of each aquifer above, within and, if potentially impacted, below the lowest coal seam to be mined) 21. In accordance with Rule 2.04.7(1)(a)(iv), ownership, uses and location information for all existing wells, springs and other developed ground water resources must be included in the permit application package. Please address the following issues: a. Wells within the permit boundary are referenced to be listed in revised Table 9 for groundwater. Page 2.04-39 references an updated Table 9 from TR13-83 in 2014. The Table 9 that the Division currently has in the Permit is from TR99-32, in 2009. Please provide the referenced updated Table 9. b. Wells located within or adjacent to the permit area are referenced to Exhibit 613, last updated in 2001. This list should be updated to ensure current data is represented. 2.04.9 Baseline Soils Information 22. Rule 2.04.9(1)(b) requires a soils analysis for representative samples of each soil horizon for each soil type for areas to be disturbed by surface operations and facilities. The Division reviewed the information contained in permit section 2.04.9, Tables 21, 22 and 23, Exhibit 15 and 16. Using Map 23c, it appears the areas affected by surface disturbance fall within the following soil mapping units depicted on Map 17: 35F, 101, 66F, 34E, 35D, 2VD, 56A, 35E, D10, ML, 2, 2C, XBD, 2F, 69C, CIO, 68D, 68C, 46E and 102. Table 23 only provides the required information from Rule 2.04.9(1)(b) for the D10 (Binco series) and areas reclaimed in 1976 and 1980. For all soil mapping units listed above, does TC have results of a soils analysis with the information required by Rule 2.04.9(1)(b)? If so, please provide this information. 2.04.11; Fish and Wildlife Resources 23. Please update the list of the Federal and State listed species of concern (Threatened, Endangered and Candidate species) contained in Exhibit 23 that may be found within the permit area. For any new species not discussed in the relevant permit sections, please update permit section 2.04.11 and the Fish and Wildlife Protection Plan in section 2.05.6 of the permit in accordance with Rule 2.05.6(2)(a)(iii). To find the most up to date lists, the following websites may be useful; USFWS- http://www.fws.gov/endangered/ CPW- http:Hcpw.state.co.us/leam/Pages/SOC-ThreatenedEndangeredList.aspx 2.05.3 Operations Plan - Permit Area 24. Map 23 shows operations continuing through 2018. Please update Table 46 to show the anticipated annual and total production for future operations at the Foidel Creek Mine in accordance with Rule 2.05.3(1). 25. Page 2.05-13-1 discusses the areal extent of the area affected by underground mining at the site. The page indicates that 13,090 acres have been affected by mining in the Southwestern, Western, Northern and Eastern Mining district. However, if you add up the acreages listed for each of the districts that total is 13,700 acres. Please clarify this discrepancy and re-evaluate and update the affected acreages listed on this page. 26. Please provide a map made in accordance with Rule 2.10 that depicts the final location of the WCR Coreholes and the location of any road that was cut to access the corehole sites.
