<br />OOJ3'~5 <br /> <br />At present the YDP is not operationally ready. In order to reactivate the <br />Plant, design deficiencies require resolution, equipment startup activities must be <br />commenced, and an environmental compliance process completed. <br /> <br />While progress has been made resolving plant design deficiencies, work <br />remains to be completed on twelve deficiencies - six of those prior to beginning <br />one-third capacity operations. Prior to commencing operation, all mechanical and <br />electrical equipment, such as valves and pumps, will require testing and, as <br />needed, repair. Wear parts, such as packing and belts, will have to be reinstalled <br />on equipment. Instrumentation will require testing and calibration. While there <br />are sufficient reverse osmosis membranes on site to support one-third capacity <br />operations, additional membranes will be required to reach and sustain full <br />capacity operations. Several major environmental compliance issues may be <br />associated with potential YDP operations: 1) update ofNEPA compliance for <br />changed conditions since the original EIS was completed in 1975; 2) obtain a <br />NPDES permit from ADEQ to allow discharge of water to the Colorado River; 3) <br />ESA compliance; and 4) compliance with the Migratory Bird Treaty Act. The <br />table below summarizes the time and funding requirements for operating the <br />YDP. <br /> <br />Table 2 <br /> <br />One third Two thirds <br />capacity capacity Full capacity <br />operation operation operation <br />Incremental one time cost (millions) $11.3 $7.3 $9.3 <br />Minimum lead time required (months) 24 6 12 <br />Cumualtive annual cost (millions) $12.9 -16.5 $19.8 -24.6 $23.6 -28.8 <br />Ranges for annual cost are the result of variability in power cost, process recovery factor, on-stream factor <br />and amortiztion period <br /> <br />E. Groundwater and drainage issues in the Yuma area <br /> <br />The Yuma area is one ofthe few areas in Arizona where there is an excess <br />supply of water. <br />However, the excess <br />supply is a problem in <br />that it is difficult to <br />remove, generally is <br />higher in salt content <br />than Colorado River <br />water, and creates an <br />additional cost for <br />pumping on top of other <br />farm operating costs. The <br />long term application of <br />Colorado River water to <br />irrigated fields in the <br />Yuma area has resulted <br />in a buildup of ground <br /> <br /> <br />,,;: <br /> <br />Recommendations of the YDP/Cienega Workgroup <br /> <br />8 <br />
