Salinity control is <br />accomplished primarily by reducing salt <br />contributions to the river from existing <br />upstream sources and by m;n;m;zing future <br />increases in salt load caused by man's activities. <br />Control measures are selected on the basis of <br />cost effectiveness, technical feasibility, social <br />and political acceptability, and environmental <br />considerations. <br /> <br />The salinity control plan will remove about <br />1.375 million tons of salt annually from the <br />Colorado River 8Y8tem by the year 2015 <br />at a remaining cost of approximately <br />$480 million. <br /> <br />Figures 5, 6, and 7 show how the salinity control <br />plan identified in 1993 meets the numeric <br />criterion at Imperial Dam, below Parker Dam, <br />and below Hoover Dam, respectively, in 2015. <br />Figures 5, 6, and 7 also show the projected <br />salinity at Imperial Dam with and without <br />further controls to the year 2015. <br /> <br />Funding <br /> <br />Public Law 93-320 and its amendment, Public <br />Law 98.569, require that a percentage of the <br />Federal cost for the salinity control program be <br />repaid from the Upper and Lower Basin water <br />development funds with revenue generated from <br />the sale of hydropower. Repayment analysis of <br />the Lower Colorado River Basin Development <br /> <br />(LCRBD) Fund prepared for the 1993 water <br />quality standards review, and thi8 evaluation <br />shows that sufficient funds are available to cover <br />appropriate costs of the salinity control plan. <br />The 1993 repayment analysis spreadsheets are <br />included in the appendix. <br /> <br />USDA <br /> <br />The current funding of $13.783 million for the <br />USDA portion of the plan greatly limits <br />implementation and hinders bringing new <br />projects into the program. About 867 farmers <br />are currently waiting to participate in the <br />program. In accordance with the Joint Agency <br />Colorado River Salinity Control Budget <br />Proposal, an annual funding level of <br />$15.9 million is needed to achieve the USDA <br />implementation schedule. <br /> <br />BLM <br /> <br />BLM expended $866,000 on salinity control <br />efforts in the Basin. Additional funding is <br />necessary for BLM to implement the salinity <br />control efforts envisioned in the 1993 Salinity <br />Control Plan of Implementation, 1993 Review. <br />Approximately $19 million is needed for fiscal <br />year 1994-97, with 60 percent of the funding <br />dedicated to implementation of control <br />measure8, maintenance of controls, and <br />monitoring the effectiveness of control practices. <br />The remaining 40 percent would fund <br />preimplementation activities suCh as <br />inventories, watershed r,mJnng, plann;ng, and <br />support. <br /> <br />11 <br />
