immediate surface disturbance vicinity, but it is not clear what length of the road <br />segment is intended to be permitted as a road for operational use (at a minimum, <br />the main segment and spurs leading to the stockpiles and sediment pond will need <br />to be permitted). The power meter light use road is not depicted on the amended <br />Surface Facilities Map. Permit narrative under "Light Use Roads", beginning on <br />page 2-32 was not updated for TR-16. <br />Please provide amended map, cross-sections, and narrative addressing <br />construction, specifications, use, and maintenance of proposed light use <br />roads. Please provide sufficient detail regarding the nature and planned <br />frequency of use to demonstrate that "Light Use" is the proper designation <br />for each of the roads. In addition, please update the current permit <br />narrative regarding the temporary light use road constructed in 2005 to <br />access the emergency drill hole on the North Fork of Munger Creek, to <br />reflect the completed reclamation. <br />Rule 2.05.3(4) Ponds.

Certain references on amended page 2-48 may no longer be applicable, upon <br />reclamation of the current sedimentation pond and construction of the TR-16 <br />proposed sediment pond. There is reference to the precleaner sediment trap (not <br />shown on revised Figure 2.2-3), which may or may not be maintained upon <br />completion of the new sediment pond. There is also reference to the 60 percent <br />sediment level as the cleanout level. <br />Please revise the narrative section as appropriate, in accordance with the <br />design for the new proposed sediment pond (please also see item 19 below), <br />and provide clarification regarding the precleaner sediment trap. <br />16. There was no stability analysis provided for the new sediment pond embankment. <br />In accordance with Rule 4.05.9, a stability analysis is required for all <br />impoundments. Statements on revised page 2-27i indicate that failure of the <br />impoundment may damage property. <br />Please provide a stability analysis for the proposed new impoundment that <br />demonstrates compliance with 4.05.9(8). <br />17. The CDPHE Discharge Permit contained in Appendix E needs to be updated with <br />the new sediment pond. <br />6
