Memorandum <br />To: Rob Zuber <br />From: Janet Binns <br />Date: 9/27/2013 <br />Re: Colowyo 2012 ARR <br />I have reviewed Section 3, Section 4, Section 8, Section 9, and Section 10 of Colowyo's 2012 Annual <br />Reclamation Report received by DMG on March 20, 2013. <br />During Permit Renewal No. 6 review CCC and CDRMS resolved total disturbance acreage discrepancies that <br />had been reported in the Division's database. Total Disturbance Area was recalculated and both CCC and <br />CDRMS concurred that the total disturbance area equals 3786.0 acres with the approval of RN6 (approved <br />April 5, 2013) and approval of RN5, July 25, 2012, for Phase III bond Release on 979.52 acres. Phase III bond <br />released acres are subtracted from the total disturbance acreage value. The CDRMS Annual Reclamation <br />Report Form has been updated to reflect this revised total disturbed area acreage value. <br />The 2012 ARR Reclamation map was included with the report as Exhibit 5A. I did not identify any <br />problems with this map. <br />2. Figure 3 -1 has an error in the acres seeded table. The Cumulative total "Acres seeded" is reported as: <br />1212.25 acres. This figure is divided into acres seeded "10 years or less ", 918.09 acres, and acres <br />seeded "greater than 10 years ", 291.45 acres. 918.09 + 291.45 does not equal 1212.25. CCC discusses <br />this 2.7 acre discrepancy in Section 3 and believes that 1212.25 is the correct total but did not correct the <br />less than ten years and greater than 10 years values to agree with the total value. <br />The operator included a table of all reclamation, year of reclamation, status of phased bond release per <br />parcel, along with notes specific to certain parcels. This type of a table is invaluable to tracking the <br />status of the reclamation parcels throughout a complex operation the size of the Colowyo mine. The <br />Division encourages the operator to continue to maintain this table in future years. Though this table is <br />not required by the Regulations, continued inclusion of this table, Exhibit 3 -2, Colowyo Reclamation <br />Table, in future ARRs will aid the Division's review of ARRs and future bond release applications. . <br />The font on this table is extremely small, extremely difficult to read without magnification and does not <br />scan into laserfiche without information being lost. The Division requests that CCC resubmit this table <br />with a legible font size (8.0 or larger). <br />4. The Division was unable to total the values in Figure 3 -2 to agree with the totals reported by CCC in <br />Figure 3 -1. Part of the inconsistency maybe attributed to the very small font size. Figure 3 -2 provides <br />reclamation totals for each year and each mining area. <br />
