surface and the horizontal extent of the potentiometric surface of each aquifer above, within and, if
<br />potentially impacted, below the lowest coal seam to be mined).
<br />Response: - The referenced baseline characterization for the Wolf Creek mining activities focuses on the
<br />suitability characteristics of the Wolf Creek Coal Seam and associated overlying interburden (Wadge Coal Seam
<br />and Wadge Overburden were previously characterized). The referenced figures and supporting text discussion are
<br />intended to characterize pre -mining baseline hydrologic conditions, and as such, it would be inappropriate to
<br />modify this information to reflect an "intermediate" condition representing a postmining or interim -mining
<br />condition. The information currently provided in the Permit addresses all applicable requirements of Rule
<br />2.04.7(1).
<br />21. In accordance with Rule 2.04.7(1)(a)(iv), ownership, uses and location information for all existing wells,
<br />springs and other developed ground water resources must be included in the permit application package.
<br />Please address the following issates:
<br />a. Wells within the Permit Boundary are referenced to be listed in revised Table 9 for
<br />groundwater. Page 2.04-39 references an updated Table 9 from TR13-83 in 2014. The Table
<br />9 that the Division currently has in the Permit is from TR99-32, in 2009. Please provide the
<br />referenced updated Table 9.
<br />b. Wells located within or adjacent to the permit area are referenced to Exhibit 6B, last updated in
<br />2001. This list should be updated to ensure current data is represented.
<br />Response: - The most current version of Table 9 is provided with these responses for replacement in the PAP.
<br />The referenced exhibit has been reviewed and updated, as appropriate. If updates were necessary, the updated
<br />materials accompany these responses for insertion/replacement in the PAP.
<br />2.04.9 Baseline Soils Information
<br />22. Rule 2.04.9(1)(b) requires a soils analysis for representative samples of each soil horizon for each soil type
<br />for areas to be disturbed by surface operations and facilities. The Division reviewed the information
<br />contained in Permit Section 2.04.9, Tables 21, 22 and 23, Exhibit 15 and 16. Using Map 23c, it appears the
<br />areas affected by surface disturbance fall within the following soil mapping units depicted on Map 17: 35F,
<br />101, 66F, 34E, 35D, 2VD, 56A, 35E, D10, ML, 2,2C, XBD, 2F, 69C, C10, 68D, 68C, 46E and 102. Table 23
<br />only provides the required information from Rule 2.04.9(1)(b) for the D10 (Binco series) and areas reclaimed
<br />in 1976 and 1980. For all soil mapping units listed above, does TC have results of a soils analysis with the
<br />information required by Rule 2.04.9(1)(b)? If so, please provide this information.
<br />Response: - Large areas within the Foidel Creek Mine Permit Area were previously disturbed by surface mining
<br />activities and were subsequently and successfully reclaimed, achieving full Phase III bond release. In addition,
<br />the baseline soils description of the PAP provides specific information for each soil type (Exhibit 16, Soil
<br />Mapping Unit Descriptions), including identification and discussion of any notable engineering or agrarian
<br />limitations. The purpose of the referenced requirement for soils analysis is to identify any suitability limitations
<br />of the soils to be disturbed relative to their use as a revegetation planting medium. The combination of previous
<br />site experience, where the disturbed soils have been successfully used in reclamation, the information provided by
<br />the detailed soil unit descriptions, and several site-specific soils investigations conducted by qualified soil
<br />scientists (as described in Section 2.04.9 of the PAP) has previously been deemed adequate to address soil
<br />suitability considerations, consistent with Rule 2.04.9(1)(b)(vi).
<br />2.04.11; Fish and Wildlife Resources
<br />23. Please update the list of the Federal and State listed species of concern (Threatened, Endangered and
<br />Candidate species) contained in Exhibit 23 that may be found within the Permit Area. For any new species
<br />not discussed in the relevant permit sections, please update permit Section 2.04. 11 and the Fish and Wildlife
<br />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
<br />to date lists, the following websites may be useful;
