D <br />Mr. Rob Zuber <br />August 17, 20151 <br />Page 2 <br />Volume 15 <br />Rule 4 <br />ITEM 45. On page 5, in the paragraph beginning with "The ongoing mining activities, " more <br />discussion is needed regarding the worst-case condition; please revise the text and (using <br />modeling results, if necessary) explain why the worst-case condition is at the time stated ("when <br />the temporary spoil pile is completely constructed') rather than at another time in the <br />reclamation process. Also in this paragraph, the second sentence should be re -written; <br />SEDCAD4 does not necessarily consider the worst-case scenario, but that is what the sentence <br />implies as it is currently written. Finally, the word "temporary" is misspelled in this paragraph. <br />Response: The fourth paragraph in Section 4.05.6 has been revised. However, the request to add <br />additional discussion for the worst case scenario has not been included. A reference that was <br />already contained within the paragraph to Exhibit 7, Item 23 has been revised to direct the reader <br />to this exhibit where the pertinent information for SEDCAD modeling, including the theoretical <br />worst case scenario for each sediment pond, is contained within the PAP. This section of the <br />PAP is not intended to present the detailed information that was requested in this adequacy <br />comment. <br />Finally, the word temporary was spelled correctly and the inference to SEDCAD presenting the <br />worst case scenario has been removed. <br />ITEM46. The introductory paragraphs for Section 4.05.13 should indicate that Colowyo <br />submits DMRs as well as AHRs. The data in DMRs are not necessarily contained in AHRs. <br />Response: The second full paragraph in Section 4.05.13 already states that Colowyo reports <br />discharges in accordance with the Clean Water Act of 1977, the approved NPDES permit, and <br />that Colowyo submits an Annual Hydrology Report annually. Therefore, no changes have been <br />made within Section 4.05.13. <br />ITEM 47. On page 7, in sentence that starts "At various times, " should the word "obtain " be <br />"detain "? If not, please elaborate on what "obtain " means. <br />Response: Obtain, as presented in the PAP narrative, means Colowyo will secure a minimal <br />discharge permit if necessary. As written, the sentence is clear, and no changes have been made. <br />ITEM 48. On page 7, in the last sentence on the page, add "and its tributaries " after "Good <br />Spring Creek. " <br />Response: The requested language has been added as requested. <br />E,; '1" t ✓W,_, :",� 1,1'I '1 7,., rt: 11I c,^i,1Pit`YFR <br />x <br />A T 11ch.tone Energv C o peramv <br />
