• PCBs -There are 148 PCB containing capacitors in use or <br />maintained at the mill facilities. These should be added as a line <br />item on the DMG task spreadsheet. Unit disposal cost per capacitor <br />is $601 as per information provided by RMCAT Environmental <br />Services, Inc. in Exhibit B for the mine. This addition increases the <br />total FW for this task from $0 to $88,985. <br />• Radiation Sources - As noted in Exhibit B, Henderson possesses 25 <br />fixed level and density radiation gauging devices at the mine and mill <br />Exhibit B). Four (4) of these sources are located at the mine and 21 <br />at the mill. As with DMG's Task 01 a, Task 05a contained no <br />provisions for disposal of radiological devises. Henderson has <br />determined that disposal of these sources amounts to $750 per <br />source for disposal and $250 per source for shipping and handling; <br />a total of $1000 per source. DMG should modify this task to add a <br />line item for radiation sources, increasing the total from $0 to <br />$21, 000. <br />3.2 Mine Site <br />3.2.1 Pond 2 -DMG ~-011 <br />Pond 2 has been backfilled with clean fill material. Therefore, DMG Task 011 is <br />moot and the total cost is reduced from $3584 to $0. A recent photo of Pond 2 is <br />included as Exhibit D. <br />3.2.2 Wood Chips/Sewage Sludge (Purchase and Haul) -DMG #01p <br />Wood chips and sewage sludge were used successfully at the Urad mine, and <br />Climax has a permitted and active biosolids program at that site. However, it <br />should be clarified that Henderson did not specifically commit to the use of wood <br />chips and sewage sludge in the original Permit. Rather, the Permit stated <br />(Section 9.8) that those materials would be used "...if available...". Section 9.11 <br />discusses the use of these materials at the mine site, then states that straw and <br />inorganic fertilizer will be used "If sewage and/or wood wastes are not available...". <br />DMG's Task 01 p estimates a total cost of $57,600 to purchase and haul wood <br />chips and sewage sludge to the mine site. Experience at Climax and at <br />Henderson over the last several years has been that these materials can be <br />6 <br />
