Cargill Partnership

In October 2019, EBDA was approached by Cargill, Incorporated with a proposal to discharge brine from Cargill’s Solar Salt Facility in Newark, California, via EBDA’s transport pipeline and outfall to the San Francisco Bay. Cargill manages a vast network of salt ponds separated from the Bay by a system of berms. Mixed sea salts (MSS) are what remains after product streams have been harvested from sea water. The ponds containing the MSS are adjacent to the Bay and could be impacted in the future by significant storms and King Tides coupled with sea level rise. Cargill is taking a proactive approach to protecting the Bay through enhanced commercial processing and accelerated removal of its inventory of MSS by sending MSS brine through the EBDA system. The proposed project includes improvements at the Newark Solar Salt Facility, including the construction of a new pump station and an approximately 15.6-mile pipeline to connect to EBDA’s system downstream of the Oro Loma Sanitary District/Castro Valley Sanitary District Water Pollution Control Facility. The brine would then be blended with effluent from EBDA’s member agencies and discharged through EBDA’s deep water outfall to the Bay.

For additional information on the proposed project, please see these slides, presented by Cargill and EBDA staff at EBDA’s March 17, 2022 Commission Meeting. A recording of the presentation and discussion are also available here.

Presentation Recording

In accordance with the provisions of the California Environmental Quality Act (CEQA) (Public Resources Code [PRC] Section 21000 et seq.), EBDA has determined that the proposed project will require preparation of an Environmental Impact Report (EIR). EBDA will serve as the lead agency for CEQA compliance.

Notice of Preparation (NOP)

On May 20, 2022 the East Bay Dischargers Authority (EBDA) issued the original Notice of Preparation (NOP) for the proposed project (State Clearinghouse [SCH] No. 2022050436) and a scoping meeting was conducted on June 1, 2022. A recording of the public scoping meeting can be viewed here: Scoping Meeting

The purpose of the NOP is to provide an opportunity for the public, interested parties, and public agencies to comment on the scope and proposed content of the EIR. The NOP is being re-issued for another 30-day review period due to a change in the location of part of the project (specifically, a portion of the pipeline alignment).

Written comments must be received by 5:00 p.m. on August 9, 2022. Please send all comments on the NOP by mail or email to:

East Bay Dischargers Authority
2651 Grant Avenue
San Lorenzo, CA 94580

Attn: Jacqueline Zipkin, General Manager
Phone: (510) 278-5910

NOTE: All comments on the original NOP will be considered; if you already commented and have no new comments as a result of the change in the project, you need not comment again.
