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.

EBDA is currently serving as the lead agency for preparation of a Draft Environmental Impact Report (EIR) analyzing the proposed project for impacts under the California Environmental Quality Act (CEQA). A formal Notice of Preparation (NOP) of the Draft EIR will be posted here when it is available.

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.
