On April 30, 2015 State and Federal lead agencies announced the proposal of a modified sub-alternative to the previously proposed Alternative 4. Alternative 4A includes the conveyance facilities proposed under Alternative 4 but does not include the elements of a habitat conservation plan and embodies a different regulatory approach for gaining necessary permits and authorizations for implementation under the Federal Endangered Species Act (ESA) and the California Endangered Species Act (CESA). The currently proposed project, Alternative 4A, is subject to environmental review under the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). The California Department of Water Resources and the U.S. Bureau of Reclamation made a partially Recirculated Draft Environmental Impact Report/Supplemental Draft Environmental Impact Statement (RDEIR/SDEIS
) available for public review and comment from July 10, 2015 through October 30, 2015.
All substantive comments received on the Draft EIR/EIS and RDEIR/SDEIS prior to the comment period deadlines will be considered in the Final EIR/EIS and decision-making process. No final decisions have been made regarding going forward with the BDCP or in selecting an alternative; those decisions will only occur after the completion of the CEQA and NEPA processes. Learn more about the public review process here. The Final EIR/EIS will be submitted to State and Federal regulatory agencies for approval and permit authorization, after which implementation could begin.
CALSIM and DSM2 Modeling Data Now Available
The CALSIM and DSM2 modeling data to support the Final EIR/EIS, which is currently in preparation, is now available. CALSIM is a model used to simulate California State Water Project (SWP)/Central Valley Project (CVP) operations. DSM2 is an extension of CALSIM which is used to model the historical hydrodynamics and electrical conductivity for the Delta and portions of the San Joaquin River.
