<br />EXECUTIVE SUMMARY <br /> <br />2 INTRODUCTION <br /> <br />3 California has historically been legally diverting more than its normal year apportionment of 4.4 <br />4 million acre-feet (MAF) of Colorado River water. Prior to 1996, California's demands in excess <br />5 of 4.4 million acre-feet per year (MAFY) were met solely by unused apportionments of other <br />6 Lower Division States (Arizona and Nevada) that were made available by the Secretary of the <br />7 Interior (Secretary). Since 1996, California also has utilized surplus water made available by <br />8 Secretarial determination. The other Lower. Division States are, however, approaching full <br />9 utilization of their apportionments, and declared surpluses of Colorado River water are <br />10 expected to diminish in future years, California, therefore, needs to reduce its consumptive use <br />11 of Colorado River water to its 4.4 MAF apportionment in normal years. In a major step toward <br />12 achieving this goal, the Colorado River Board of California developed California's draft <br />13 Colorado River Water Use Plan (California Plan). The California water agencies consisting of <br />14 The Metropolitan Water District of Southern California (MWD), Coachella Valley Water District <br />15 (CVWD), Imperial Irrigation District (lID), and San Diego County Water Authority (SDCWA) <br />16 negotiated the Key Terms for Quantification Settlement (Key Terms), and developed a draft <br />17 Quantification Settlement Agreement (QSA). The QSA, which is described in more detail below <br />18 and in Chapter 2, establishes a framework of conservation measures and water transfers <br />19 between the participating agencies for a period of up to 75 years, These provide an important <br />20 mechanism for California to reduce its diversions of Colorado River water in normal years to its <br />21 4.4 MAF apportionment. <br /> <br />22 PURPOSE AND NEED <br /> <br />23 The Secretary, pursuant to the Boulder Canyon Project Act (BCPA) and Arizona v, California, <br />24 1964 Supreme Court Decree (Decree), proposes to take Federal actions necessary to support the <br />25 implementation of the QSA, The purpose of the Federal action is to facilitate implementation of <br />26 the QSA, which inco orates contractual a reements necessary for California to reduce its use <br />27 0 Colorado River w<tl:,er. The need for the Federal action is to assist California's efforts to <br />28 reduce its use of Colorado River water to a 4,4 MAF apportionment in a normal year. This <br />29 reduction in California's use of Colorado River water would benefit the entire Colorado River <br />30 Basin. <br /> <br />31 DESCRIPTION OF THE PROPOSED ACTION AND ALTERNATIVES <br /> <br />32 This Environmentallm act Statement E1S) describes the potential environmental impacts of <br />33 the proposed action, which is the execution of an mp emen allon greemen a wou <br />34 commit the Secreta to makin Colorado River water deliveries m accoraance WIth the terms <br />35 an conditions of the IA to enable implementation of the OSA, and related accounting and <br />36 en:::lTonmental actions. The three major components of the proposed action are as follows: <br /> <br />37 . Execution of the lA, wherein the Secretary agrees to changes in the amount and/or <br />38 location of deliveries of Colorado River water that are necessary to implement the QSA. <br /> <br />lA, lOP, and Related Federal Actions EIS <br /> <br />DEIS -January 2002 <br /> <br />E5-1 <br /> <br />~ <br />
