The Bureau of Reclamation and the California Department of Water Resources (DWR) are proposing to prepare a joint Environmental Impact Statement/Environmental Impact Report (EIS/EIR), pursuant to the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), to evaluate effects of the proposed Reach 4B, Eastside Bypass and Mariposa Bypass Low Flow Channel and Structural Improvements Project (Project) under the San Joaquin River Restoration Program (SJRRP).  The Project is a component of the San Joaquin River Settlement (October 2006) and is located in Merced County.

The Project includes the construction, operation, and maintenance of a low flow channel in Reach 4B of the San Joaquin River and in the Eastside and Mariposa Bypasses and improvements to facilities in the Eastside and Mariposa Bypasses to allow for fish passage.  The purpose of the Project is to comply with the San Joaquin River Settlement by improving conveyance capacity in Reach 4B of the San Joaquin River to ensure conveyance of at least 475 cubic feet per second (cfs), modifying the Eastside and Mariposa Bypass channels to establish a low flow channel, and modifying structures in the Eastside and Mariposa Bypasses to provide for fish passage. 

There will be a 30-day scoping comment period for the Project from Wednesday, September 9, through close of business Friday, October 9, 2009.  The purpose of public scoping is to solicit comments from interested stakeholders to assist in determining the scope of the EIS/EIR, including the alternatives to be addressed, and to identify any significant environmental issues related to the Proposed Action. Two public scoping meetings will be held to solicit public input on alternatives, concerns, and issues to be addressed in the EIS/EIR.  The two scoping meeting dates are:

Because the functions of these channels are interrelated, the design, environmental compliance, and construction are being addressed as one project.  The planning and environmental review is authorized under Section 3406(c)(1) of the Central Valley Project Improvement Act (Title 34 of Public Law 102-575) and the San Joaquin River Restoration Act (SJRRA)(included in Public Law 111-11).  Construction of the Proposed Action is authorized under the SJRRA.
