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. Analysis Prepared by : Alf W.
