This would be a good time to officially <br />request that Seneca updates the ownership and control information in the Yoast permit. Please <br />have Seneca update dte Yoast permit with the new owners and controllers of the <br />permittee/operator. <br />Reclamation Cost Estimate <br />The reclamation cost estimate was conducted by Seneca for the permit term 1995-1999. It was <br />determined from the operations plan map (Exhibit 12-1), that the highest liability would occur in <br />1997. My specific comments are as follows; <br />Seneca used equipment cost which date back to 1991 and 1992. Seneca should update <br />the estimate with current equipment cost data. This update applies to all equipment used <br />in the estimate to reclaim the Yoast Mine. In the past, Seneca has used costs approved by <br />the Division. Attached are costs and production data worksheets, derived from the Cos[ <br />Reference Guide & Contractors Equipment Cost Guide, that Seneca may elect to use. <br />Please provide these data work sheets to the operator. <br />2. Seneca estimated the cost to remove structures and facilities from the Yoast mine using <br />the 1995 edition of Means. Seneca should update the cost associated with this task using <br />[he 1998 edition of Means. <br />
