INTEROFFICE MEMORANDUM TO: ROB ZUBER FROM: JANET BINNS SUBJECT: COLOWYO PR4 ADEQUACY REVIEW DATE: 7/13/2015 CC: I have reviewed Colowyo's submittal of Permit Revision No. 4 for compliance with the regulations and guidelines, and agreement with the previously approved. As requested I reviewed sections: 2.04.9, 2.04.10, 2.04.11(5), 2.04.12, 4.06, and 4.15 for both the South Taylor/Lower Wilson mining area and Collom mining area. Section 2.05.4(2)(e) was reviewed as well, to assure no changes were made in this section. The majority of the sections changes were limited to page formatting and pagination changes. Few substantive changes in the text were made. No changes to previously approved data, or success standards were proposed. Only one adequacy concern was identified: 1. Please request CCC correct Table 2.04.9-16: a. The date should be corrected. The table currently reads, "Collom topsoil balance as of March 13, 20151". Please correct the date to reflect 2015. b. Line 3 of the table "Lands yet to be retopsoiled (Line 1 minus Line 2)" Line I = 2352.8 acres. Line 2 = 0 acres. The result for line 3 states that "0" acres are yet to be retopsoiled. The Division believes that the acres for Line 3 should read "2352.8 acres". Please review and correct this line. c. Line 4 is labeled "Lands yet to be retopsoiled". This line appears to be a repeat of Line 3. d. Correction to line 3 and 4 will also affect the result of Line 7. Please make the appropriate correction once the other lines have been corrected. 2. Section 4.15.8 Revegetation Success Criteria states that, "Consideration will be given to a revised species diversity standard in the context of a comprehensive revegetation plan revision to be submitted by Colowyo Mine, following approval of PR -02." PR -02 was approved on May 4, 2007. TR -72, Revised
