Bay Delta Conservation Plan / California WaterFix

Return to: Watershed EIS Comments

EPA is participating in the development of the Bay Delta Conservation Plan (BDCP)/California WaterFix. The Bay Delta Conservation Plan was a habitat conservation plan proposed by the California Department of Water Resources, U.S. Fish & Wildlife Service, National Marine Fisheries Service, and Bureau of Reclamation, under the Endangered Species Act, to address the most critical water issues facing California by constructing new water delivery infrastructure and restoring aquatic habitat. In 2015, the Bay Delta Conservation Plan was recast as California WaterFix with a focus on the construction and operation of proposed new water export intakes on the Sacramento River to divert water into a proposed 40 mile twin tunnel conveyance facility.

EPA's role is twofold: first, to review and rate the environmental documentation produced for BDCP/WaterFix under the National Environmental Policy Act, and second, to ensure that any necessary Clean Water Act permits required for the project restore water quality and protect aquatic resources.

  • Recent EPA Correspondence with the BDCP Lead Federal Agencies  

Today, the California State Water Project (CVP) and the Central Valley Project (SWP) are operated to comply with permits under the federal and state Endangered Species Acts and Clean Water Acts. The list below contains links to information about these regulatory instruments. These permits would be adjusted or replaced if BDCP is approved and implemented.
