California WaterFix Book TABLE OF CONTENTS California WaterFix Overview Materials for Discussion and Decision Compiled by the Kern County Water Agency 1 California WaterFix Overview NOTE TO READERS This overview was compiled by Kern County Water Agency (Agency) staff from materials prepared by Paul Weiland and Rob Thornton at Nossaman, LLP, Stefanie Morris, general counsel for the State Water Project Contractors, the Metropolitan Water District of Southern California (Metropolitan) and Agency staff. The Agency thanks Paul, Rob and Stefanie for their contributions, as well as Metropolitan for allowing the Agency to use large portions of its “white papers” on physical facilities of California WaterFix1 and operation of the California WaterFix.2 This overview is a public document and is intended to assist landowners, Agency Member Units and the Board of Directors with making decisions related to California WaterFix. Agency staff has compiled this overview from the best available information developed over 11 years of study and analysis performed by the California Department of Water Resources (DWR). DWR worked with the California Department of Fish and Wildlife (CDFW), the U.S. Bureau of Reclamation (USBR), the U.S. Fish and Wildlife Service (USFWS), the National Marine Fisheries Service (NMFS) and a broad range of stakeholders to develop the concept for California WaterFix, and to perform the environmental analysis necessary to comply with the State and federal Endangered Species Acts, the California Environmental Quality Act and the National Environmental Policy Act, as well as several other State and federal environmental permitting requirements. This draft version of the overview includes information on the infrastructure that will be constructed, and how that infrastructure will be operated. Additional information on the cost allocation methodology and potential methods for financing California WaterFix will be provided in the next version. At the time this version of the overview was released, the environmental compliance for California WaterFix was complete for the State Endangered Species Act in the form of a 2081 permit issued by CDFW and for the federal Endangered Species Act in the form of Biological Opinions from USFWS and NMFS. Permits were in process for compliance with sections 401 and 404 of the Clean Water Act, and a permit for a change in point of diversion was under consideration by the State Water Resources Control Board, but potential issuance of that permit was more than a year away. Additional review is necessary by the Delta Stewardship Council, but has not yet started. 1 Modernizing the System: California WaterFix Infrastructure. http://www.mwdh2o.com/DocSvcsPubs/WaterFix. 2 Modernizing the System: California WaterFix Operations. http://www.mwdh2o.com/DocSvcsPubs/WaterFix. 2 California WaterFix Overview TABLE OF CONTENTS TABLE OF CONTENTS Introduction ................................................................................................................................................ 6 Background Current Regulatory Context and Forecasted SWP Reliability Purposes of California WaterFix Why Build It Now?
