Modifications to the Approved Reclamation Plan <br />TR -90 will have a minor impact on the approved reclamation plan due to limited infrastructure demolition <br />and removal costs. The largest impact on the approved reclamation plan is the storage and disposal of <br />elemental mercury which CC&V intend to handle and store in compliance with all federal standards. <br />CC&V has purchased a 1 ton mercury flask, designed to store approximately 2,200 lbs of elemental <br />mercy indefinitely (see Attachment 3). The I ton mercury flask specifically designed for mercury <br />containment, transport and long term storage, meets all Department of Transport (DOT) requirements to <br />ship and store elemental Mercury whilst also complying with MEBA storage requirements. Based on the <br />maximum accumulation recovery scenario, CC&V estimates it will take 6 to 7 years to fill the 1 ton flask; <br />however CC&V estimates filling time is actually greater than 10 years. <br />To ensure a simple yet practical bonding approach, CC&V will store only one operational one ton flask <br />on site at any given time. To ensure ongoing compliance with federal regulations, CC&V proposes this <br />bond will be all encompassing and include costs to transport the Mercury to a treatment facility for <br />refinement, 10 years of long term storage and the estimated fee to dispose of the flask at the DOE facility. <br />At final closure, the retort will be decommissioned, decontaminated, microencapsulated, and disposed of <br />in a hazardous waste land fill. CC&V has provided an estimate from a specialty Waste Management <br />contract to undertake the decommissioning and decontamination of the retort (see Attachment 4). <br />Once decontaminated and removed, the only remaining demolition work will include removal of concrete <br />and miscellaneous steel supports. <br />CC&V has used costs associated with Newmont's Nevada operations to calculate the increase in <br />reclamation cost, Documentation is provided in Appendix B. Table 3 below contains a reclamation cost <br />estimate to reflect the additional reclamation liability incurred by the State. All costs include equipment <br />and labor. With the approval of TR -90 the required financial warranty will be increased by $75,400 or <br />what the State determines to be the increase in reclamation liability. <br />Table 2: Proposed reclamation liability associated with the retort project <br />TR -90 Reclamation cost estimate <br />Task Description Dimensions Units Cost per unit Total Cost <br />Demolish concrete for concentrate storage <br />building including; slab, concrete walls, and <br />truck load out 4 CY 32.13 128.52 <br />Demolish, Decommission, microencapsulate <br />and dispose of Retorts stem 1 <br />Retort <br />system 20,836.20 20,836.2 <br />Demolish supports for the retort, chiller, and <br />stack 0.5 tons 200.00 100.00 <br />Transport one ton flask to refining facility, <br />refine, and ship to long term storage 1 Flask 8,560.00 8,560.00 <br />Ten Years of Long term Storage one ton flask 10 years 1,200.00 12,000.0 <br />Disposal with DOE (estimate) 2,200 lbs 10.00 22,000.0 <br />Sub total 63,624.72 <br />DRMS total costs % 18.5 <br />Total cost 75,395.29
