Cattany <br />Division Direcor <br />Natural Resource Trustee <br />The Division of Minerals and Geology (DMG) has completed review of the 2004 Annual Reclamation <br />Report (ARR) for the Rimrock Strip Mine. The report was reviewed in conjunction with the request <br />for final bond release (SL-02) for the mine. So that our records reflect that all disturbed acres at the <br />site have been properly released from bond, it is important that the final reclamation report reflect <br />values that are consistent with our forthcoming Phase II bond release findings. I reviewed past ARR's, <br />permit text, SL-02 maps, and previous file documents to arrive at the values presented in the table <br />below. Mainly, they vary only slightly from previous values reported. <br />Disturbed area acres Granted Phase I <br />reviousl ~ Comments <br />Main it 10.0 Yes SL-01 <br />TS stock ile foot rint .81 Yes SL-01 <br />Two drill sites .10 Yes SL-01 <br />Access road area .31 Yes SL-01 <br />Sediment and .fi4 Yes SL-01 Ma have been remature <br />Sediment ditch .56 No Part of and desi n Ian <br />Oil Tank Containment .20 No <br />Subsidence feature .00 No <br />Total 12.62 <br />Please review the attached draft of the 2004 ARR and, if you concur with the values as represented, <br />please download a new form from our web site, fill it out, and resubmit it to our office.
