Box 483 <br />Paonia, CO 81428 <br />Re: Bowie No. 2 Mine (Permit No. C- 1996 -083) <br />Technical Revision No. 79 (TR- 79) <br />Material Storage Area Expansion <br />Dear Mr. Bear: <br />COLORADO <br />ID IV I S I O N O F <br />RECLAMATION <br />MINING <br />SAFETY <br />John W. Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Pineda <br />Director <br />The Division has completed a preliminary adequacy review of the technical revision application (TR -79) <br />submitted by Bowie Resources, LLC (BRL) for the Bowie No. 2 Mine. The revision proposes to expand <br />the material storage area northeast of the B Seam Portals. We have the following comments and <br />questions regarding the application. <br />1. It would appear that revised watershed details for Ditch C -8, on page Exh -8 — 66 were inadvertently <br />omitted from the submittal, since the ditch and culvert information on pages EXH. 8 -29 and EXH -8 — <br />31 both indicate reduced runoff from this area and Map 21 -2 indicates that the contributing <br />watershed has been reduced. Please revise page Exh -8 — 66, the Ditch C -8 watershed information, <br />to be consistent with Map 21 -2 and the peak flows for Ditch C -8 and Culvert C -7 that are listed on <br />the tables on pages EXH. 8 -29 and EXH -8 — 31. <br />2. On page EXH -8 — 31, the contributing flow for Culvert C -G4 which receives drainage from Ditch D -5 <br />was revised from 0.86 cfs to 0.00 cfs. It appears that this was in error, since ditch D -5 and Culvert C- <br />G4 should not be affected by the material storage expansion. Please further explain the change to <br />the culvert inflow or restore the information to the currently approved version (TR -76, November <br />2012). <br />If you have any questions or need additional information, please contact me. <br />Sincerely, <br />Susan L.
