Co vo/ 103+05 <br /> 303 761 =/ 30 | ,^" aca-r^,-zeoz <br /> TECHNICAL MEMORANDUM <br /> June 2O. 2O18 <br /> To: Ray Lazuk' Environmental Manager, Climax Mina <br /> Ron Valentine, Engineering Manager, Climax Mine <br /> From: Steven M. Mo|y, P.E. <br /> VV. VV. Wheeler @ Associates, Inc. <br /> Re: 1051.27: 5 Dam Seepvvoter Return System Modification Plans <br /> The purpose of this memorandum is to describe the plans for modification of the 5 Dam Seepwater <br /> Return System that become necessary as the elevation of Movf|owerTSF increases duo to <br /> tailings deposition. The timing of the need for the various modifications is dependent upon mine <br /> production rate and is estimated below. The modification plans have been designated by o <br /> number for reference and are described below: <br /> Plan 1 <br /> This plan is shown on Figure 10 and consists of the current configuration and operation of the <br /> system. The seepvvmbar is pumped through the existing 24''/14^ HOPE pipeline from the <br /> K8ovf|ovver Pump Station to the collection pond at the toe of 3 Dam. This system has been in <br /> operation for several years. <br /> Modification Plan 2 <br /> This plan in also shown on Figure 1m and may become necessary if the existing pipeline across <br /> &4avOovverTSF becomes dmgged, crushed, or otherwise unusable. If this onoure, the existing <br /> Quarter Cutout Valve will be opened and the seepwater will be conveyed through the TDL North <br /> Cutout Channel to K8avf|ovverT8F. If the timing is such that the North Cutout Pipeline has been <br /> installed, then the seepwater will be conveyed to Mayflower TSF through the pipeline. <br /> c\1oom1os1no51.znonn\zo1omvisionnoosuV_momv_n'uam-soopwotor-p|ono.uoox <br />
