Unauthorized Discharge |
According to the discharger's 5-day report, the discharge was not directly observed, but likely occurred on December 31, 2022, due to a major storm event. The discharge was likely composed of comingled stormwater and potable water and discharged directly to the San Francisco Bay. From the report, "storm water flows breached the storm water retention berm, and the flow at this location caused a potable water line to break. Potable water then combined with accumulated storm water and breached a second of the Facility?s storm water retention berms; this comingled potable and storm water is believed to have discharged off-site." |
