SEDCAD analyses or design information for the temporary diversion ditches in "Part <br />A". (Pate A contains the SEDCAD information for the permanent post-mining <br />drainages.) These temporary channels will need to be designed, constructed and <br />permitted in a similar manner to the permanent post-mining channels. These <br />channels will also need to be described in the operations plan in Section 2.05.4 and <br />shown on a map of appropriate scale (possible Map 23B Mine Plan Collom Area). <br />Please provide descriptions, plans, channel profiles, maps and SEDCAD modeling for <br />all proposed diversions within the permit area. <br />22. This item remains incomplete. Colowyo has provided modeling for the proposed <br />post-mining drainages as Exhibit 7, Item 25. The Division, however, will not <br />consider the construction of permanent post-mining drainages along hillsides and <br />slopes that are not part of the natural drainage pattern of the post-mining topography. <br />Reconstructed drainages like Deer Draw, Elk Draw, Bear Draw, Little Bear Draw, <br />and Little Fox 1 are some of the proposed channels that are not topographically <br />controlled by the post-mining topography. The long-term function and stability of <br />these drainages is in question. These drainages must be reconfigured/rerouted to a <br />more natural location within the post-mining topography. These changes will need to <br />be made prior to reviewing any of the other modeling. The remaining drainage <br />designs are complete, but will be reviewed for adequacy. <br />Rule 4 .05.4 - Stream Channel Diversions and Stream Channel Reconstruction <br />23. This item remains incomplete. Colowyo states that they are planning to divert three <br />streams in the Little Collom X and Collom Lite Pits during mining. These stream <br />channels are two small tributaries of Little Collom Gulch (diverted around Little <br />Collom X) and the main channel of Little Collom Gulch. The original PR-03 <br />submittal stated that the information is contained in Section 2.05.6 and Exhibit 7, <br />Item, 23. The required information was not, however, included in the original <br />submittal. In the 29 March 2010 response Colowyo did provide Exhibit 7, Item 27 - <br />Diversion Channels During Mining. The referenced item is two charts with no <br />supporting detail or documentation. In the opening paragraph to Exhibit 7, Item 27 <br />Colowyo states "(t)he supporting SEDCAD4 analyses and watershed maps are <br />presented as attachments to Part A." The Division is not in possession of any "Part <br />A". These temporary channels will need to be designed, constructed and permitted in <br />a similar manner to the permanent post-mining channels. These channels will also <br />need to be described in the operations plan in Section 2.05.4 and shown on a map of <br />appropriate scale (possible Map 23B Mine Plan Collom Area). Please provide <br />descriptions, plans, channel profiles, maps and SEDCAD modeling for all proposed <br />diversions within the permit area. <br />Rule 4.05.13 - Ground Water Monitoring <br />24. This item is considered complete. Colowyo has provided a lengthy discussion stating <br />that a groundwater point(s) of compliance is not necessary in the Collom mining area. <br />Based on the submittal of this discussion, the Division finds that this portion of the <br />Colowyo Mine C-1981-019 page 7 of 11 8 April 2010 <br />Permit Revision 03 - Collom Permit Expansion
