C-1981-008 PR-06 PAR 22-Jan-2010 Page 11 of 26 spillways elevation are labeled at 5571.00' indicating that there is an embankment and there, are spillways. If there is an embanlonent then the provisions of Rule 4.05.9 Impoundments applies to this structure. Please clarify the information contained in Attachment 2.053(3)-20 regarding principal and emergency spillways for Pond 015, otherwise revise the attachment to include all of the permit information required by Rule 4.05.9 for this structure. 29. The information presented in Attachment 2.05.3(3)-7 Small Area Exemptions is confusing and needs to be further clarified. On page 2 of the revised attachment, WFC states that "The 2009 permit revision eliminates all remaining SAE's with the exception of the topsoil stripping area ahead of the pit." This contradicts with text on pages 3 and 4 of the attachment where WFC indicates that some of the SAE's are existing and some are planned. Further none of the SAEs could be located on a map including SAE#6 as stated on page 4 of the attachment. Please clarify the discrepancies identified in Attachment 2.05.3(3)-7 and submit revised pages and maps accordingly. Rule 2.05.42)(c) Backfillina and Grading Plan 30. On the List of Attachments and on the cover pages to Attachments 2.05.4(2)(c)-5 and -6, San Miguel has been misspelled ("San Maguel' ). Please correct the spelling at these locations. 31. Dates in the middle of page 5 have been changed to reflect reclaimed land contours as shown on Map 2.05.4-1. The revised text says contours for the years 1993 to 2001 are shown. We believe that 2007 is intended rather than 2001. Please review and revise as appropriate. 32. The Small Depressions section on page 6 seems to imply that Pond 014 will be retained as a postmining feature. Section 2.05.3(3) states the opposite. Please clarify the intended postmining status of Pond 014 and revise the text as necessary. 33. The Final Pit Backfilling section on page 6 states that Map 205.4-1 shows "typical" cross sections. The sections on the referenced map are true cross sections, and not "typical". Please change the map being referenced or delete the word "typical", as appropriate. 34. According to the first paragraph of the new proposed Western Mining Area Backfilling section on pages 6 and 7, "The maximum slope in this area is 5H: IV with a few exceptions, which is very good for the post mine land use of dry rangeland.." Revised Map 2.05.4-5, Postmining Vegetation / Land Use Map, gives Dryland Pasture, not "dry rangeland" as the requested postmining land use for the WFC parcel. Additionally, the sentence quoted above does not clearly describe the topography as shown on revised Map
