<br />states that, as regards industrial and municipal effluent <br />~ limitations, the State of Colorado adopted a policy which <br />~ does not set a limit on salt concentration and that the <br />C) State of Wyoming did not adopt a policy at 'all. <br />-J <br /> <br />EDF's statement regarding the State of Colorado is in <br />error because Colorado has adopted the Forum policy as <br />presented in Appendix A in its entirety. In 1975 the State <br />of Wyoming adopted the salinity standards for the Colorado <br />River which included in the implementation plan the policy <br />of no-salt return whenever practicable for industrial <br />dischargers. While Wyoming has not yet adopted the policy <br />presented in Appendix A, that policy will be considered for <br />adoption as regulation at the same time as the 197$ Revision <br />of the Forum Report. <br /> <br />Oil Shale - EDF states that the report fails to recognize <br />that the modified in-situ process, proposed for two Colorado <br />leases will result in leaching large quantities of salts <br />from the retorted shale when groundwater is allowed to fill <br />back the mine voids. <br /> <br />The Forum adheres to the general policy of no-salt return <br />whenever practicable for industri~l discharges. This policy <br />applies also to the oil shale industry. It should be <br />recognized, however, that specific problems will require <br />specific solutions and that the states and EPA, not the <br />Forum, have enforcement authority. <br /> <br />Coal Slurry Pipelines - EDF contends that coal slurry <br />pipelines will result in accelerated use and depletion of <br />basin'water resources with attendant increases in salinity. <br /> <br />The Forum recognizes that any consumptive use of water <br />will have an impact on available resources and on salinity. <br />However, the use of water for coal slurry pipelines will not <br />have a greater impact on resource availability and salinity <br />than out-of-basin exports or in-basin industrial uses with <br />no-salt return, and will have a lesser impact on salinity <br />than other in-basin uses. If water having a salinity greater <br />than about 750 mg/l (one ton/acre-foot) is used for coal <br />slurry pipelines, the impact of such use would be a decrease <br />in salinity in the lower main stem under present hydraulic <br />conditions. <br /> <br />Conclusion - EDF concludes that the Forum's implementation <br />plan will fail to meet the goal of maintaining river salini- <br />ties at 1972 levels because, according to EDF, the Forum <br />neglects the major controllable sources; namely, agriculture <br />and other (unspecified) land-use related sources.
