Rule 4.033 - Lieht-Use Roads 3. Rule 4.03.3(4)(c) requires that ditches, cross drains, road surface drainage culverts, and ditch relief drains shall be installed as required by the Division to control erosion for light-use roads. A culvert or swale (Arizona crossing) is required to transfer runoff from the east side of the road to the west side of the road where it joins the main haul road neaz the cross-over. No such design was found in revised pages of the application. The Division requests that Colowyo include a revised permit page containing a design for a culvert or swale. 4. Rule 4.03.3(5)(a) requires that light-use road surfaces shall be adequate for the use of the road. Based on the Division's discussions with Colowyo, the proposed road is being designed as a dozer road. The Division requests that Colowyo include an updated page to the permit text that states what the use of the road will be and what the road surface will be. Rule 4.05 - HvdroloEic Balance 5. It is the Division's opinion that drainage from the area of proposed disturbance is captured by a ditch that flows into the Work Area Pond. Even if this road is exempt under the road "best management practices" provisions, the drainage pattern and flows in the existing ditch will be altered. The Division requests Colowyo to review and validate, and modify as may be necessary, the storm water plans for runoff from this area into the collection ditch (higher elevations, west side) to the Work Area Pond. [Rule 4.05.2(1)] Rule 4.06 - Topsoil 6. The Division requests that Colowyo provide an updated page to the permit text describing topsoil salvage, storage and replacement to the proposed light-use road. Please include the location of the existing topsoil stockpile if necessary. See also Rule 4.03.3(3)(f). Miscellaneous 7. Map 22 shows various power-transmission lines within the Colowyo Mine permit boundary. One set in particulaz seems to be mislabeled. On the map, by the primary crusher, it appeazs as though severa14,160V lines have been mislabeled as 4,160KV lines. The Division requests that Colowyo check the labeling on Map 22 and correct as necessary. If the map is corrected, please resubmit two copies of the map certified by a registered, professional engineer as required by Rule 2.10.
