Bonding <br />Bonding calculations are presented on pages 72 and 89 of the permit. The <br />site is currently bonded for E54,130.00 in the form of a Certificate of <br />Deposit. The bond calculations follow the generalized or intuitive <br />nature of the reclamation plan and although they include all necessary <br />items the assumptions are not clearly stated. The Division has <br />recalculated the reclamation costs utilizing standard unit costs from the <br />CAT Handbook, Means Construction Cost Data, and the CRG Machinery Rate <br />Guide. The total calculated reclamation cost was E67;581.00. The cost <br />worksheets and tables from the Division's calculations are enclosed. <br />These costs may be summarized as follows: <br />Although several of the line items in this estimate are different, the <br />total direct costs are similar. The mayor difference in the estimates is <br />the inclusion of indirect costs in the Division calculations. These are <br />costs which would be incurred by the Division in contracting site <br />reclamation to a third party. <br />- 7 - <br />
