Mr. Joseph Dudash - 2 - October 16, 2001 <br />Structural Demolition (Task 9061 <br />The division itemizes costs for the removal of "Radial Stacker #1"and i[s footings for <br />$19,218. This stacker and footings were removed during the installation of the downhill <br />conveyor and should be removed from the demolition calculation. <br />Under the heading of Clean Material Storage Areas, the Division itemizes costs for the <br />removal of mist disposal items for $14,507 for the "Old Truck Loadout" azea. This area <br />no longer exists as a material storage area. <br />4. Fill vent shaft (Task 85e1 <br />If this task is for [he Freeman Gulch vent shaft, then it is calculated in error, because the <br />Freeman Gulch vent shaft is only 6 feet in diameter while this calculation indicates a <br />diameter of 18 feet. If this task is for the Fan Shafr on the Utility Bench, then the backfill <br />calculation may be in error as to volume of backfill material (18' diam x 14' - ?). If this <br />item is for the fan Shafr, the reclamation expense for the filling of the Freeman Gulch fan <br />Shafr may be missing from the calculation. <br />Furthermore, according to the approved permit map, Map 29, there is no requirement for <br />a steel saddle or concrete plug for the sealing of ventilation shafts a[ the Bowie No. 2 <br />Mine. Bowie intends to seal the shafrs in accordance with the approved plan. Please note <br />that the ventilation shaft has been fully grouted and lined from top to bottom and the vent <br />shaft in Freeman Gulch is grouted through a water producing zone. Neither shaft <br />penetrates an aquifer. Reclamation costs for these shafrs should therefore be calculated <br />only as the cost of placing backfill material into the shafts and capping them with an 8 inch <br />slab and then placing 4 feet of cover material over the caps. <br />Please contact us with any questions or concerns regazding this submission with copies of <br />all written correspondence sent to Mr. Wm. A. Bear, Jr., P. O. Box 483, Paonia, CO 81428. <br />Sincerely, <br />%~~<~G~ <br />' J. E. Stover, P. E. <br />Consulting Engineer <br />
