I Department of the Interior salinity control units; McElmo Creek, Lower Gunnison Unit-Stage I, Big Sandy River Unit, lfiD .0 (h ...... Sinbad Valley Uhit, and Saline Water Use and Disposal Opportunities Unit; and authorize a new voluntary cost-share onfarm salinity control program for the Department of Agri- culture. The proposed legislation also would modify the cost sharing and repayment provisions. The Administration has also introduced legislation, HR 3903, which would authorize only the Department of Agriculture program. That legislation has passed the House and is on the Senate floor. As was done in previous standards review, using the Recla- mation's salt routing model, the Forum made a number of pro- jections of future salinity concentrations in the Colorado , River using a number of combinations of water supply, water use, and salinity control measures. As an example of the projections of future salinity concentrations with and without control measures made using a 14-million-acre-foot water supply, and a low depletion level indicate that there are adequate sal~- nity control measures included in the plan of implementation to maintain the criteria at the three lower mainstem stations through the year 2000. The estimated salt load reduction from the salinity control units, level 4, considered in this review when fully implemented is 1,920,000 tons. The state-adopted standards, approved by EPA, allow for temporary increases above the criteria level of the salinity control measures are included in the plan. The 1984 review retains that same provision allowing for temporary increases above the numeric criteria. The Forum has demonstrated by
