be a parameter used to evaluate revegetation success for pastureland. Also please update the <br />species diversity evaluation section of the permit to discuss how diversity will be evaluated for <br />the reclaimed pastureland area. <br />49. Please update Map 29 to depict the approved disturbance areas associated with the following <br />revisions: <br />a. CRDA Soil Stockpile Relocation (MR290) <br />b. 10 -East Mid Panel Emergency Borehole (MR289) <br />c. 5 -Main North Cement Borehole and Pipeline (MR288, MR285, MR283) <br />d. WCR Coreholes/access roads (MR281, MR280, MR278, MR277, MR276, MR275) <br />e. TRO Coal Quality Coreholes/Access Roads (MR272, MR269) <br />50. TC identifies four types of reclaimed communities that will be established at the site (Sagebrush <br />Grassland, Sagebrush Meadow, Pastureland and Hay Cropland). It is unclear what parameters <br />will be used to define if a reclaimed parcel falls within the designated reclaimed community. <br />Please update section 2.05.4(2)(e) of the permit to define this criteria. <br />51. Rule 2.05.4(2)(g) requires a description, including appropriate cross sections and maps prepared <br />in accordance with 2. 10, of the measures to be used to seal or manage mine openings, and to plug, <br />case, or manage exploration holes, other bore holes, wells, and other openings within the <br />proposed permit area, in accordance with 4.07. A description is provided starting on page 2.05- <br />119 of the permit. Figure 15 shows a Typical Portal Seal to be used in reclamation. However, <br />there is no reference to maps or cross sections provided as required by the rule. A very general <br />figure is provided for the portal seal but cross sections and maps were not found with regard to <br />other mine openings. Please either provide this information or update section 2.05.4(2)(g) of the <br />permit to cite the location of this information within the permit. <br />2.05.4(2)(h)- Compliance with Clean Air Act, The Clean Water Act and other applicable water quality <br />laws, re-ulations and health and safety standards <br />52. DRMS was unable to locate Exhibit 10 NPDES Permit CO -0036684 and Exhibit 5 NPDES <br />Permit CO -0027154. Please address the following: <br />a. Please either inform DRMS where the affore mentioned exhibits reside in the permit or <br />provide these exhibits to DRMS for inclusion in the permit. <br />b. Are all the permits (MPDS and air pollution) still active and necessary? If they are no <br />longer active please provide language in the permit stating that a specific permit number <br />is no longer active and has been terminated. <br />2.05.60(a)(i), (iii), and (iv) —Protection of the Hydrologic Balance <br />53. Sampling frequency issues pointed out in the DRMS Review of the 2014 Annual Hydrology <br />Report, specifically items 11 and 16 concerning Exhibit 14. TCC will need to address any item <br />where a specific monitoring requirement was not met. Please either submit the data or explain <br />why the data was not collected. <br />54. TC will need to evaluate the concerns identified in item number 24 of the DRMS Review of the <br />2014 AHR data and the PHC (section 2 05 6 3 of the permit) regarding surface hydrology <br />impacts. TC will need to address the following item: <br />a. For the lower reaches of Middle Fish and Trout Creek, the projected average conductivity <br />sulfate and TDS levels for 2009 to 2015 contained in Exhibit 32 do not appear to be <br />reflective of the average levels reported in the 2014 AHR. The averages reported for <br />these parameters exceed the average projected amounts. TC will need to evaluate these <br />Foidel Creek Mine -12- 11/23/2015 <br />
