The revision updates the drainage and sediment control information in the currently <br />approved permit application package, in response to deficiencies identified during recent <br />inspections. We have the following comments and questions regarding BRL's response and <br />revised application materials. <br />1. Issue resolved; BRL provided the requested certification pages for Volumes III and XI. <br />2. BRL provided a revised page EXH- 8 -29i, as requested. However, there are additional issues <br />that were identified on the revised table submitted with BRL's September 24, 2014 <br />response to Item 2: <br />a. BRL revised the V -Ditch Design table on page Exh 8 -29i using a flow value of 16.41 for <br />Ditch D2. TR -84 revised the value for Ditch D2 to 9.7 cfs (corrected precipitation <br />amount for 100 -yr storm). Please revise the flow value for Ditch D2 to be consistent <br />with the previously approved value of 9.7 cfs. <br />b. The currently approved permit application includes a page Exh. 8 -29i followed by a page <br />Exh 8- 29iii. Please repaginate existing page Exh. 8 -29iii or submit an intentionally <br />blank page Exh 8 -29ii. <br />p co, <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us I <br />John W.
