oonSoi Federal Register I Vol. 46. No. 126 I Monday. July 6. 1981 I Notices 35062 Basin. The average normal salinity Ic\"cls not to be exceeded are i23 mgll below Hoover Dltm. 747 mg!1 below Parker Dam. and 879 mgll below Imperial Dam. all in the Lower Colorado 58,in. V. Water Requirements fot Synfuela Development Estimated demands on Regional energy resources were developed by DOE through disaggregation of the naUonal energy demand forecasts for the yean 1985 and 2000. Two levels of synthetie fuels development in the Region were forecast-a baseline and an accelerated development level. The baseline case wall based on the principal assumption thal.ynfuels development would proceed according to a "business al usual" pace. The accelerated case was based on the assumptions that: .ynfuels development would suhstilute for a grealer portion of dOOlestic gas and oil and reduce foreign imports; would have Federal financial support?' would have an optimistic degree of succeaa in early market penetration: and production costs would make the product competitive. A. Patterns of Synfuels De~'e/opmcnt Hypothetical siti"8 pallems were then developed for the projected levels oJ development according to location of 011 shale and coal deposits and water availability. Table 3 sbows the projected siting for the year ZOOO for !he ba,eline and accelerated case projections. Information for 1985 has been excluded because of the small scale of projected development and Its relative unimportance to the overall questions of water supply adequacy and water- related impacts. 3. Federal and Indion Re8erYed Rights. Tille to various quantities of water is cUrTently held by the Federal Government and II number of Indian tribes under the legal principlea of Federal resen-'ed water right.. Because these reserved rights are generally not being used, cu.rrent water IIvailability is lillle affected. Future reserved right claims and awards could. however. affect the availability of water for other purposes. 4. Environmental Regulatory Laws and Programs. A number of Federal laws and programs. although not directly involved with water allocation and use, indirectly affect potential development and/or ill associated water impliCllllons. Those most pertinent to synfuels development In the Region are: (1) Fish and Wildlife Coordination Act (PL BS-Z64) (2) National Wild and Scenic Rivera Act (P.L 90-542) {31 Endangered Species Act {p.I.. 9~ 2lJ5} (41 Wildemen Acl(P.L 88-Sn) {5} Clean Water Act (P.I.. 92-SOO. sa amended by Pl.. 95-217). 10 addition 10 the foregoing. the leven States of the Colorado River Basin have adopled a joint objective of maintAining salinity in the lower main lltem of the Colorado River al or below the average value found during urn. while continuing to develop their compact. apportioned waters. Numeric IlIlinil)' criteria have been approved by each of the State. and the U.s. Environmental Proteclion Agency at three downstream locations. Although lubject to change. the criteria pose constraints on water use and development in tbe Upper judicial nor the executive branch of Slate government has discretionary authority over the type, place. or quantity of use. The remaining Upper Basin States. however. use a panni! syslem in which the Stale Engineer must approve the right to appropriate water. frere. the State Engineer may deny an application If it is delemdned to be contrary to the "public interest:' All Upper Basin States (1) allow water rights to be claimed as of the dilte the application was received even though actual use Is deferred for 8. period of years; (2) allow for tbe transfer of a water right from one use to another. one owner to another. or one location to another: and (3) disallow Instream now use as a basis for granting a private water right. Only Colorado law Includes inlllream now uses and provides for ~ State acquisition of a water right in an amount necessary "to preserve the natural environment to a reasonable degree." Stale laws governing the appropriation of groundwater have similarities. Colorado's procedures are probably the most alringent. Groundwater in Colorado Is classified as either tributary or nontributary. Decause tributary groundwater Is hydraulically connected to a surface stream. it is included in the statutory dl'flnilion of a nstutal stream and admlnlstered under the surface priority system. Nontributary groundwater. which is found in confined formations oflen under artesian pressure. is administered by the Stale Engineer through a permit s)'lItem thallimlB the amount of annual withdrawal to 1 percent of the water in storage below the applicant's property. t ~ T.bl. 3.-5yrrthetic Fu8Is o.nl~,j"'ll' PII~ . . .lo.<IIc..
