Order No. Linked To Enf. 1147749 05/12/2025 Unauthorized Discharge Per the May SMR: On May 12, 2025, approximately 240,000 gallons of secondary treated, disinfected wastewater was discharged to Islais Channel at Discharge Point No. EFF-002 (Quint Street Outfall). The discharge started at approximately 07:34 am and ended at approximately 08:04 am. The cause was a faulty bubbler level indicator at the Booster Pump Station and inability to automatically switch to a redundant level control using the Distributed Control System (DCS). Violation null Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N 1144051 04/15/2025 Order Conditions Oakport WWF: Approximately 21,350 gallons of fully treated effluent was discharged through the outfall to East Creek Slough when the effluent gates did not fully close when staff was operating the plant in practice mode (what EBMUD calls a wet test). The discharge only lasted about 15 minutes since it was quickly discovered and responded to.

INF flow was not maximized while discharge from the Westside Transport/Storage Structure to Discharge Point 001 occurred. This resulted in approximately 6.6 MG of wastewater being discharged as decant rather than 3.1 MGD receiving primary treatment and 3.5 MGD receiving secondary treatment at OSP.
