Document Description
The project would enable the enhanced processing and removal of up to approximately 600,000 tons per year of mixed sea salts (MSS) in existing ponds at Cargill's Solar Salt Facility in Newark, CA by harvesting additional liquid bittern from the MSS matrices in these ponds as commercial product, dissolving the residual MSS solids in the ponds using San Francisco Bay water, and transferring the resulting brine to the East Bay Discharger Authority's (EBDA's) combined effluent pipeline for discharge into the Bay under EBDA's National Pollutant Discharge Elimination System permit. The MSS brine would be discharged to the EBDA system at a rate of up to approximately 2.0 million gallons per day over an approximate 10- to 15-year timeframe. The proposed project has an onsite component of pipelines and pumping facilities within the existing Solar Salt Facility and an offsite component that would involve construction of approximately 15.6 miles of new underground pipeline primarily within roadway rights-of-way to connect the Solar Salt Facility into EBDA's system just downstream of the Oro Loma Sanitary District/Castro Valley Sanitary District Water Pollution Control Plant in San Lorenzo.
