RN07 <br />Page 18 <br />5/30/18 <br /> <br />reclaimed parcel falls within the designated reclaimed community. Please update Section 2.05.4(2)(e) of the <br />permit to define this criteria. <br /> <br />Response: - Generally, mine disturbance areas will be reclaimed to the dominant vegetation type for the area within <br />the disturbance boundaries, most closely corresponding to the premining vegetation community for that area, a s <br />indicated by the Premining Vegetation mapping (Maps 18 and 18A). One of three approved seed mixes <br />(Pastureland, Cropland, Rangeland, Tables 53 – 55) will be utilized, depending on the dominant premining <br />community. For both the Sagebrush Grassland and Sagebrush Meadow, the Rangeland seed mix will be utilized, <br />and the vegetation community that develops will be differentiated only by the dominant topographic and moisture <br />conditions. Supplemental text has been added to clarify these considerations and copies of the revised text <br />accompany these responses for replacement in the PAP. <br /> <br />Resolved <br /> <br />51. Rule 2.05.4(2)(g) requires a description, including appropriate cross sections and maps prepared in <br />accordance with 2.10, of the measures to be used to seal or manage mine openings, and to plug, case, or manage <br />exploration holes, other boreholes, wells, and other openings within the proposed Permit Area, in accordance <br />with 4.07. A description is provided starting on page 2.05-119 of the Permit. Figure 15 shows a Typical Portal <br />Seal to be used in reclamation. However, there is no reference to maps or cross-sections provided as required <br />by the rule. A very general figure is provided for the portal seal but cross-sections and maps were not found <br />with regard to other mine openings. Please either provide this information or update Section 2.05.4(2)(g) of <br />the permit to cite the location of this information within the Permit. <br /> <br />Response: - All mine openings are identified in Section 2.05.3(2) (pages 2.05-11.1 and 2.05-11.2), described in <br />Section 2.05.3(3), and their locations shown on Map 24 (Mine Facilities and Freshwater Systems). The detailed <br />descriptions provided on pages 2.05-119 through 2.05-121 adequately describe the plugging and sealing methods <br />to be used to secure the various types of mine openings. The addition of cross-sections would not provide any <br />additional relevant information, would not necessarily be representative, given differences in the size and type of <br />mine openings, and is not necessary or appropriate. <br /> <br />2.05.4(2)(h)- Compliance with Clean Air Act, The Clean Water Act and other applicable water quality laws, <br />regulations and health and safety standards <br /> <br />52. DRMS was unable to locate Exhibit 10 NPDES Permit CO-0036684 and Exhibit 5 NPDES Permit CO-0027154. <br />Please address the following: <br />a. Please either inform DRMS where the afore-mentioned exhibits reside in the Permit or provide these <br />exhibits to DRMS for inclusion in the Permit <br />b. Are all the permits (NPDS and air pollution) still active and necessary? If they are no longer active <br />please provide language in the permit stating that a specific permit number is no longer active and has <br />been terminated <br /> <br />Response: - Based on the current Table of Contents, Exhibit 10 should be; Geochemical Analysis of the Wadge <br />Seam, included in the confidential appendices, and Exhibit 5 should be; Pasture Management Practices in the <br />Twentymile Park Area. Under the response to Comment 10, TC has updated the information on other permits <br />applicable to the Foidel Creek Mine operations. In reviewing the PAP, several discharge permits appear to be <br />scattered among the Exhibits. In order to simplify location and referencing of these documents, all discharge
