          SUMMARY  :  Incorporates effects of climate change into current  
          water planning efforts and requires report on greenhouse gas  
          effects of various water supply options.  Specifically,  this  
          bill  :  

          1)Requires the Department of Water Resources (DWR) to  
            incorporate analysis of the potential effects of climate  
            change, to the extent applicable, into all reports or plans  
            that DWR is required to complete.

          2)Requires DWR to identify available information or develop its  
            own information regarding climate change and water resources,  
            and make such information available on its Web site.

          3)Prohibits DWR from approving an integrated regional water  
            management grant, for applications submitted after January 1,  
            2009, unless the underlying plan considers the information  
            identified by DWR or other climate change information.

          4)Requires the State Water Resources Control Board (SWRCB), in  
            cooperation with DWR, Air Resources Board, the Energy  
            Commission and the Public Utilities Commission, to complete a  
            study that quantifies energy savings and greenhouse gas  








                                                                  AB 224
                                                                  Page  2


            emission reductions from water recycling and water  
            conservation.

          5)Requires the SWRCB and the regional water quality boards, in  
            developing water quality control plans, to consider a  
            reasonable range of hydrological, temperature and sea-level  
            rise scenarios resulting from climate change.

          6)Requires water suppliers that prepare urban or agricultural  
            water management plans to obtain climate change information  
            from DWR, identify the possible effects of climate change on  
            water supply projections and consider such information when  
            developing the conclusions of such plans.

          7)Makes legislative findings regarding climate change and water  
            resources.

           EXISTING LAW  requires DWR to provide local assistance to water  
          agencies on issues related to statewide water management.  SWRCB  
          regulates water rights and water quality, including certain  
          permits for recycled water.

           FISCAL EFFECT  :  Assembly Appropriations Committee estimates  
          costs of:  $500,000 in 2007-08 and 2008-09, to the Department of  
          Water Resources to develop and analyze climate change  
          information; $700,000 primarily in 2008-09, to the State Water  
          Resources Control Board to complete study of climate change  
          effects from various water supply enhancement options.

           COMMENTS  :  AB 224 begins the process to incorporate climate  
          change information into the water resource planning efforts of  
          state and local agencies.  The Assembly Water, Parks, and  
          Wildlife Committee held a hearing on the issue of climate change  
          and water resources in February 2007, in which it heard about  
          the increasing body of evidence and scientific studies showing  
          how climate change has and will affect water resources  
          management in California.  Several of the larger urban water  
          agencies already have begun assessing how to change their  
          operations to address climate change concerns.  This bill would  
          require water agencies that already are required to prepare  
          water supply reports to incorporate climate change into those  
          reports.

          1)Resolving Uncertainty By State-Identified Information:  As  








                                                                  AB 224
                                                                  Page  3


            introduced, this bill inserted climate change analysis into  
            various statutory water planning requirements.  Concerns were  
            raised about the uncertainty of which climate change  
            information was reliable enough to consider.  The author  
            consolidated these diverse climate change analysis  
            requirements into a new part in the Water Code, required DWR  
            to identify which information should be used, and then  
            specified that use of DWR-specified information was  
            sufficient.  Alternatively, a water supplier may use other  
            information in its possession.  If DWR does not identify such  
            information, then local water suppliers are exempt from these  
            requirements.  The author asserts that State specification of  
            information resolves any questions of uncertainty as to which  
            information should be used.

          2)SWRCB Study of Greenhouse Gas Production:  AB 224's  
            requirement of an SWRCB study on effects of water use on  
            climate change responds to a 2005 California Energy Commission  
            report.  That report found that California's water use  
            consumed about 19% of its electrical energy, which creates  
            greenhouse gas emissions.  Water recycling and conservation  
            were found among the least "energy-intensive," particularly  
            for urban areas reliant on imported water.  This bill would  
            require the SWRCB to look at this issue in greater detail, in  
            coordination with certain other relevant agencies.  This study  
            will help California learn more about the other side of the  
            climate change/water supply equation - the effect of water use  
            on climate change.  The SWRCB currently is addressing recycled  
            water issues as part of a statewide policy, addressing  
            differences among the regional water quality board.  This  
            study will contribute to the development of this State policy,  
            and the water boards' implementation of recycled water use  
            regulation.
