barge to the west corner of East Branch Reservoir. The pump barge will consist of three <br />vertical turbine pumps enclosed in a heated enclosure. Power will be supplied to the barge <br />through a proposed transmission line that would extend from East Branch Pump Station to <br />the barge. The entire system has been designed for year -round operation. The design <br />pumping capacity of the barge system is 12,700 gpm (28.3 cfs) with all three pumps running. <br />The design of the new barge system includes a lateral at the upper end of the <br />pipeline that will allow the barge to be used in emergency situations to deliver water from the <br />tailing pond directly into the existing fresh water bypass system at the bifurcation structure. <br />This water could then be conveyed to the Williams Fork River. To use this lateral, it will be <br />necessary to remove a blind flange on the lateral and install a pipe spool piece. A blind <br />flange must then be attached to the normal discharge end of the barge discharge pipeline. <br />This positive separation design was intended to eliminate the possibility of unintended <br />discharge of process water into the fresh water system. The capacity of this system will also <br />be 12,700 gpm (28.3 cfs). The design capacity of the fresh water bypass system from the <br />bifurcation structure to the Williams Fork River is 82 cfs. <br />5 <br />
