Technical analysis and testimony in support of the Tosco NPDES permit appeal
San Francisco Bay, CA
Flow Science provided analysis of dilution and mixing of storm water from two Tosco Refinery sites located on San Francisco Bay. The analysis demonstrated that tidal transport and mass fluxes of elements within San Francisco Bay waters are significant, and that the cooling water discharges experience large amounts of dilution within short distances of the discharge locations. Flow Science provided testimony to the State Water Resources Control Board in the successful appeal of an NPDES permit that had denied a dilution credit for this discharge.
