. . ~ .If) r:\J t"'J FACT SHEET - CENTRAL ARIZONA WATEIl CONTROL STUDY c.:. The Central Arizona Water Control Stut!y was undertaken after lIub1ic cOlll11ent on the Draft Environmental Impact Statement for Orme Dam revealed considerab1~ public concern over the environmental, economic, and social impacts of the project. Todays decision on plan implementation is the result of 5-1/2 years of intensive study and widespread public cOlll11ent. The Central Arizona Water Control Stut!y is the largest public involvement effort ever undertaken by the Bureau of Reclamation. Nine plans were studied by the Bureau of Reclamation during the process of making its recolll11endations. Six plans were presented for review, plus a "no action" plan. The decision represents an adoption of Plan 6. Plan 6 allows for regulatory storage to onerate the Central Arizona Project in the most efficient manner and permits the State of Arizona to more comnletely utilize its Colorado River entitlem~nt. Plan 6 also orovides flood control benefits ant! safety of dams work. The ma,ior comllonents of Pl an 6 are New Waddell Dam on th~ Agua Fri a River, modification of Roosevelt and Stewart ~ountain Dams on the Salt River, and Cliff Dam on the Verde River. Cost sharing is a necessary element in our efforts to accomplish Plan 6. President Reagan on January 24 outlined the Administration's policy o~ cost sharino -- seeking new partnership arrangements with States and other non-Federal interests, whereby project beneficiaries should ultimately bear a substantial part of the cost;~roject development. ~s for safety problems at Federal dams, the PresidE'nt sait!, "The cost of safety work should be borne by the Federal Government. However, if additional economic benefit results from the modification, aonropriatE' cost sharing among the beneficiaries shall be allocated by the Secretary." The initiation of preconstruction activities on Cliff Dam will have to wait until a study to review and evaluate issues concerning potential impacts caused by its construction is completed. This report is to be submitted within 180 days. The Department of the Interior will proceed with the ~esign and sl\ecifications for New Waddell, Stewart Mountain, and Roospvp1t Dams as caoabi1ity permits. All designs and specifications will include the recolll11endations from the National Academv of Sciences study on ris~ analysis as aOnroved by the Secretary of Interior. March 30, 1984 the Rureau of Reclamation and the Army Corps Of Enoineers entered into a Memorandum Of Understanding providing for joint fundinq and direction of a study to develop criteria for Dam Safety t!esignation, as set
