The AWBA may not own, develop, operate, or construct storage facilities, Instead, the A WBA is to take advantage of existing storage sites by contracting to reserve storage capacity at existing permitted facility(s), The AWBA has been charged with the duty to prepare and assess an inventory of existing storage facilities to determine whether they are available to meet the AWBA's needs for the next ten years, and the inventory is to be updated at least once every five years, The initial inventory completed in March 1997 with ADWR review found that storage facilities do not exist in the Tucson Active Management Area (AMA) to meet the AWBA's needs. The AWBA found that storage facilities exist in the Phoenix and Pinal AMAs to meet their needs, The A WBA found that no storage facilities are necessary to meet their needs in areas of the State outside the Phoenix, Pinal, and Tucson AMAs, There are no storage facilities currently existing outside the Phoenix, Pinal, and Tucson AMAs capable of physically receiving and storing CAP water. The Storage Facilities Inventory (Appendix B) provides a listing of existing storage facilities sufficient to meet AWBA needs in Arizona (AWBA 1997); . The A WBA has indicated that water stored pursuant to a SIRA would be stored in existing State permitted facilities in which the A WBA has contracted storage space. The consuming State entity will be required to pay for the delivery and storage of the water and could then receive a quantity ofICUA attributable to 95% of the stored quantity; . Nevada has limited off stream storage capacity, The Las Vegas Valley Water District began recharging Colorado River water in the Southern Nevada Groundwater Bank in 1987. Through 1996, approximately 110 kaf had been recharged, with plans to recharge at least 350 kaf, This water is used to meet the Southern Nevada Water Authority purveyor's demands including summer peaking. Studies continue on ground water recharge, Nevada has not identified any storage facilities that would be used in interstate transactions and is unlikely to develop any for this purpose, Nevada most likely would be a consuming State, At present, Nevada entities have not developed provisions related to interstate transactions; . In California, the Desert Water Agency (Desert) and the Coachella Valley Water District (CVWD) entered into agreements with MWD to recharge the groundwater basin of the upper Coachella Valley with Colorado River water, Under those agreements, MWD exchanges Colorado River water for water available to Desert and CVWD from the California State Water Project under those agencies' water delivery contracts with the State of California, Those groundwater storage sites have the potential for use to store water for interstate transactions, It is unknown if California entities will develop any offstream storage facilities for use in interstate transactions, This analysis assumes that California will be a consuming State; and . MWD also has a program that involves contracting with its member agencies for groundwater recovery, MWD's 1995 annual report lists the following projects: six projects under contract with a projected ultimate yield of 18,039 af/yr, three projects 7
