There is an addition error on the Division's Annual Reclamation Report form in Exhibit 3A. Colowyo reports that the cumulative total disturbed acreage is 3,840.46 acres. The Division believes that the total should be 3,937.25 acres. The formula for cumulative total disturbed acreage is acres in active mining plus acres in long-term mining or reclamation facilities plus cumulative acres backfilled and graded. Additionally, the cumulative total disturbed acres listed on the ARR form (3,840.46 acres) is more than that permitted for the life of the mine (3,837.00 acres). Please review the acreage numbers reported on the form and make the necessary corrections and resubmit the Annual Reclamation Report form in Exhibit 3A. Colowyo's Response: In 2004, Colowyo reported a cumulative total of 3, 761.96 acres. During 2005, Colowyo disturbed 78.50 acres. By adding the cumulative total from 2004 (3, 761.96) and adding to it the acres disturbed in 2005 (78.50) a total of 3, 840.46 acres was generated and consequently reported to the Division. Colowyo believes this calculation is fairly straightforward The discrepancy identified by the Division reflects the same acre volume that was reclaimed in 2005 (96.79 acres). 6. Section 8 details the regraded spoil sampling as required in the PAP. In preparing this report the Colowyo Mine used suspect levels that have since been changed (Minor Revision 76, approved by the Division on 27 January 200b). The new suspect levels are contained on page 2.05-8 of the PAP and will apply to all future overburden sampling. One of the suspect levels contained on the table on page 2.05-8 needs to be changed. It is noted that sample I-21 shows a SAR level of 6.11. While this is not above the suspect level for the 2005 sampling program, it will be above the suspect level for the 2006 sampling, triggering additional sampling and possible remedial actions. Colowyo's Response: Colowyo has an approved Suspect Level Sodium Adsorption Ration of I5. Colowyo has not put forward any changes or mod f cations to suspect levels as related to SAR based on MR-76. Thus, Colowyo feels no action is required in this matter. 7. Permit page 2.05-8 states that Colowyo will sample the regraded spoil on 500- foot centers (approximately one sample every five acres). The Division does not have a copy of any map that shows the regraded spoil sampling locations. Please provide the Division with a copy of a map that shows all regraded spoil sampling areas. Colowyo's Response: Colowyo uses a map for internal tracking purposes that can be reviewed during your next site inspection at your request.
