Permit Revision Adequacy Comment Response <br />November 30, 2004 <br />Page 3 of 24 <br />~, <br />;.04.6 Geology Description <br />6. The Division requests that MCC retain Tables 2 and 3 in the text. They had been <br />deleted from the submitted text. <br />MCC Response: MCC inserted Tables 2 and 3 into the text. <br />7. In the discussion of B-seam (page 2.04-23) the Division requests that MCC add <br />language to discuss the South-of-Divide permit revision area but not delete the existing <br />discussion as it currently exists in the PAP. The information there is valuable and should not <br />be lost to the PAP. <br />MCC Response: MCC added the discussion to the text. <br />8. On page 2.04-25, the last sentence in section "E-seam Reserves" states "mining plans <br />do not include reserves in the northwest portion of the permit area." Should that state <br />"northwest portion of the SOD permit addition?" Please correct and clarify. <br />MCC Response: Language was added to clarify the South of Divide mining reserves. <br />9. In reference to page 2.04-30, it is requested that MCC add mapped faults to the geology <br />map (Map 9.) <br />MCC Response: Changes were made to Map 9. <br />10. Regarding the discussion on page 2.04-31, please discuss whether any indications have been <br />identified of surface or groundwater resources in the SOD area being associated with faults. <br />MCC Response: A discussion was added to the text regarding water resources and faults. <br />11. In the "Rockfall" section on page 2.04-39, please discuss the potential effects of subsidence on <br />rockfall. <br />MCC Response: MCC has included additional text and Exhibits addressing rockfall <br />potential. <br />12. On page 2.04-4I the first sentence on the page is extremely important. Please make certain that <br />the reference for that statement is clear. <br />MCC Response: Alan Mayo re-wrote the exhibit and text to clarify the statement. <br />13. On page 2.04-41, 1st paragraph, "age" is more appropriately referred to as "residence time," <br />consistent with the Mayo report. <br />MCC Response: MCC has made the changes for consistency. <br />
