The addendum provides information <br /> regarding an elevation raise of the sludge cell co tainment berm for the Sludge Densification Plant(SDP) <br /> located adjacent to the Tenmile Tailing Storage acility(TSF). <br /> The sludge cell is located within the footprint of he Tenmile TSF as shown on the attached drawing. The <br /> sludge'cell berm was raised in 2012 to separate tl ie sludge cell contents from the tailing that was being <br /> deposited in the TSF with the resumption of min g and milling activities at Climax. Climax intends to <br /> continue depositing tailing within the TSF in acc rdance with TR-20 and needs to increase the height of the <br /> berm another 7 feet from its current elevation. S ilar to the 2012 construction and as shown on the attached <br /> drawing,Climax will place tailing material to rai a the core of the berm and then place rip rap to prevent <br /> erosion of the slope. The best material for rip ra that is durable and accessible is rock from the North 40 <br /> Overburden Stockpile Facility(described in TR- 2). Climax will haul and place up to 5,000 cubic yards of <br /> this material along the outer face of the SDP berr.i. <br /> The North 40 material is nearly identical in chemical composition as the tailing that will be deposited around <br /> it. Also,all water from this area is contained and is either used in the milling process or is treated and <br /> discharged in accordance with CDPS permit CO 000248. <br /> Please accept this letter and attachments as an addendum to TR-20 for your files. Climax also will maintain <br /> this information with our copies of TR-20. <br /> Sincerely, <br /> 1 P-5114 <br /> Raymond Lazuk <br /> Environmental Manager <br /> attachments <br />
