This effort was expanded and a <br /> <br />planning team was fomed during 1986 and chal:ged with reevaluating the <br /> <br />desalting plant operations and identifying any structural or nonstructural <br /> <br />plans with the potential of reducing YDP operating costs. <br /> <br />J <br /> <br />The Reclamation plarming team identified 48 plans for m:x:Iifying the <br /> <br />operation of the desalting plant to reduce operation and maintenance costs. <br /> <br />This report provides a representative sanple of the type of alternatives <br /> <br />examined by the planning team. The Lower Colorado Region is continuing to <br /> <br />work with the Basin states on potential nethods to reduce costs of <br /> <br />operating the YDP and on alternatives to develop a source of reject stream <br /> <br />replace.""",L water that would be acceptable to the Basin states. The <br /> <br />alternatives presented in this report fall into boo categories--six in <br /> <br />Category A and nine in Category B: <br /> <br />Category A contains exanples of those alternatives examined by the <br /> <br />Planning Team which m:x:Iify operations of the YDP to reduce costs or <br /> <br />identify alternative (less costly) power sources for YDP. (Power costs are <br />approximately 25 percent of the total O&M cost.) <br /> <br />Category B contains exanples of those altematives examined by the <br /> <br />Planning Team that would develop alternative sources of water to replace <br /> <br />the reject stream or which reduce the required plant operating tine or <br />capacity. <br /> <br />O[l')n ,~~:j r!, <br />,1 g. fj~ ~ ~ ,>; ,: " ;, <br />~ '....
