Ms. Robin Reilly, CDMG <br /> Re: RN-08 Permit Renewal <br /> Page 13 <br /> 7. For PR9 Task 133 was included as costs provided by the operator. DRMS has the operator information <br /> for his task from PR9. Please update the costs for his task and supply DRMS with costs to include in the <br /> RN8 cost estimate. <br /> 8. DRMS has operator supplied costs for Task 127 in PR9 from Trapper Appendix A13.6 for sealing <br /> Monitoring wells. Please provide an updated cost estimate for these tasks for inclusion in the RN8 cost <br /> estimate. <br /> Trapper Response: <br /> 7. See attached Table ]. Task 133 as presented in PR-9 was derived from values calculated in Table A-5.1 <br /> of the Appendix A, PR-9 estimate. These values are based on the approved PMT and WCB as presented in <br /> PR-9. The BCY and Highwall Length are based on these designs. Costs have been updated with current <br /> rates as derived from recent CIRCES runs. A small increase in cost for this task is calculated with these <br /> current cost factors. <br /> 8. See attached Table 1. The as-built lengths and diameters for the CY series ofwells drilled near Covote <br /> Impoundment dam have been included with current updated costs as derived from CIRCES. <br /> Please contact me if you have any questions or concerns with the attached information. <br /> Sincerely, <br /> .Z�- ��/- <br /> Graham Roberts <br /> Environmental Supervisor <br /> GCR <br /> [M/Permit Renewals/RN-08/Response to DRMS Preliminary Adequacy Comments.doc] <br /> Encl <br /> c Revisions File <br />
