1119117 06/25/2023 Unauthorized Discharge Per the June SMR: On June 25, 2023, approximately 11.8 MG gallons of secondary treated, disinfected wastewater was discharged to Discharge Point No. EFF-002 (Quint Street Outfall). The discharge started at 7:42 a.m. and ended at 12:23 p.m. The cause was a loss of power to the Booster Pump Station (BPS), which pumps final effluent to Discharge Point No. 001 (Pier 80 Outfall). On Saturday June 24 at approximately 3:30 p.m., PG&E power to BPS was interrupted after PG&E infrastructure was damaged in a traffic accident. SFPUC Operations staff confirmed the issue after a field inspection at BPS. They began to recirculate wastewater flows within the plant and stored flows in upstream Transport/Storage (T/S) Boxes. Staff maintained communications with PG&E and on-call SFPUC electricians to prepare for power restoration. As of Saturday evening, PG&E had not provided an estimated timeframe for restoration. In anticipation of the possibility that power would not be restored before the Channel T/S Box capacity was exceeded, orders were issued to initiate discharge of treated effluent through the Quint Street outfall when Channel T/S Box level exceeded 290 inches to prevent a discharge of untreated wastewater. Channel T/S Box level exceeded this threshold at approximately 6:15 a.m. on Sunday June 25, 2023. Effluent flow to Discharge Point No. 002 commenced at 7:42 a.m. with an average flow rate of 60.5 million gallons per day (MGD). Power to BPS was restored at approximately 12:10 p.m. and discharge to Discharge Point No. 002 ceased at 12:23 p.m. All effluent discharged through Discharge Point No. 002 received full secondary treatment and disinfection. When PG&E power to BPS was restored, SFPUC electricians performed necessary electrical work to verify PG&E power and operating circuit breakers prior to restarting the pumps at BPS. Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1119109 03/17/2023 Unauthorized Discharge Per March SMR: On March 17, 2023, approximately 115,000 gallons of secondary treated, disinfected wastewater was discharged to Discharge Point No. EFF-002 (Quint Street Outfall). The discharge started at 6:31 a.m. and ended at 6:40 a.m. The cause was an issue with transitioning one of the effluent pumps at the Booster Pump Station (BPS) from local control to automatic level control upon re-starting of the plant after a SEP shutdown. SEP was shut down on March 16 for construction activities for the Headworks Project. As part of the shutdown, BPS pumps were switched to local control for a planned sump inspection. The plant was re-started on March 16 at approximately 6:00 p.m. but one of the pumps was not switched from local to automatic control. As flows to SEP increased on the morning of March 17, the BPS pump still in local control did not start, resulting in the final effluent channel levels rising above the weir and effluent flowing to the Quint Street Outfall. Operations staff were immediately notified by a control system alarm when the discharge started and ceased the discharge by opening valve V20 to divert effluent flows from the Quint Street Outfall to the Islais Creek Transport/Storage Structure. Instrumentation & Controls (I&C) staff investigated the issue, including testing the controller logic for all pumps, and verified that the pumps were functioning as programmed. Daily composite samples collected and analyzed for COD and TSS were not elevated. Hourly total residual chlorine monitoring confirmed that the final effluent was fully dechlorinated. No adverse effects on Islais Channel were expected or observed during a visual survey performed at 6:40 a.m. Receiving water samples were collected for enterococcus on March 17 and 18, and concentrations were well below the applicable standard and SFPUC posting threshold. Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1119108 03/28/2023 Order Conditions Per the March SMR: On March 21 and 28, San Francisco experienced two bomb cyclone events, bringing damaging winds, power outages, and flooding rains throughout Northern California. During the March 21 and 28 CSD events, SEP did not have an influent flow rate of at least 240 MGD. On March 28, a local power issue at 2:12 p.m. caused the BPS pumps to trip and shut off. Operations staff went onsite at 2:20 p.m., investigated the issue, and requested electrician support. Electricians fully reset the pumps at 2:46 p.m. and BPS flow achieved 110 MGD within 10 minutes. As a result of this power issue, an estimated additional 1.5MG ? or approximately an additional 11.7% ? was discharged in the Central Basin (12.49 MG, total CSD event volume). Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1119107 03/21/2023 Order Conditions Per the March SMR: On March 21 and 28, San Francisco experienced two bomb cyclone events, bringing damaging winds, power outages, and flooding rains throughout Northern California. During the March 21 and 28 CSD events, SEP did not have an influent flow rate of at least 240 MGD. On March 21, a PG&E power outage at BPS occurred at 3:45 p.m. while SEP was discharging 250 MGD. The power outage shut down BPS, which limited SEP discharge to Discharge Point No. 002. SEP continued to maximize secondary treatment at about 150 MGD and the SEP influent flow rate was 153 MGD (average) during the CSD to Islais Channel, which started at 8:40 p.m. SFPUC electricians restored BPS operations on March 22 at approximately 5:50 p.m., after PG&E restored power. As a result, an estimated additional 45.1 MG ? or approximately an additional 24% ? was discharged in the Central Basin (188.16 MG, total CSD event volume). Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1119106 03/09/2023 Order Conditions Per the March SMR: During the March 9-10 storm, two issues at the Channel Pump Station (CHS) limited influent pumping from CHS to SEP. As a result, an estimated additional 10.0 million gallons (MG) ? or approximately an additional 14% ? was discharged in the Central Basin (125.40 MG, total CSD event volume). On March 9, the CHS pump rate reached 80 MGD before a CSD to Mission Channel starting at about 8:56 p.m. Later that night, the CHS flow rate dropped to zero due to the following issues: (1) At approximately 9:30 p.m., power issues tripped the CHS pumps. Staff responded by restarting the pumps at 10 p.m. (2) On March 10 at about 1:30 a.m., the frame on the CHS downstream influent throttling gate detached from the hydraulic actuator. CSDs to Mission and Islais Channels were occurring during these incidents. Thereafter, CHS was shut down because the gate failure prevented pumping; staff responded by removing bolts and other materials that could potentially damage the bar screens and pumps. CHS was restarted manually at approximately 8:30 a.m. Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1119105 04/15/2023 CAT1 Carbonaceous Biochemical Oxygen Demand (CBOD) (5-day @ 20 Deg. C) Weekly Average limit is 40.0 mg/L and reported value was 69.0 mg/L at EFF-001. Violation None Report SF - OCEANSIDE Water Pollution Control Plant 437599 R2-2019-0028 Y

1115328 02/23/2023 Order Conditions During the February 23-24 overnight storm, the Channel Pump Station (CHS) pump rate reached 80 MGD before there was a CSD to Mission Channel from the Central Basin. During the CSD to Mission Channel from Discharge Points CSD-024 and 025, however, the CHS flow rate periodically dropped to less than 80 MGD due to the pumps tripping. As a result, an estimated additional 0.44 million gallons (MG) ? or approximately an additional 0.6% ? was discharged in the Central Basin (69.61 MG, total CSD event volume). Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1115326 01/09/2023 Order Conditions During the January 9 CSD event at the Mariposa outfall (Discharge Point No. CSD-029), MPS reached peak wet weather capacity (10 MGD) when the Mariposa CSD started but did not maintain that peak flow rate throughout the CSD event. Power issues during the storm caused the pumps to stop at 4:30 a.m. As a result, an estimated additional 0.26 million gallons (MG) or less than an additional 0.1% was discharged in the Central Basin (431.47 MG, total CSD event volume in Central Basin). Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1115323 12/31/2022 Order Conditions On New Year?s Eve at approximately 10:10 a.m., one of the two Northshore wet weather pumps (which provide flow to the North Point Wet Weather Facility) was out of service because a control board on the variable frequency drive (VFDs) failed. An electrician qualified to work on high voltages was called in from standby and was able to restore manual operation of the pump by 1:50 p.m. The pump was run in manual mode for all subsequent wet weather events until January 12. The temporary decrease in pumping to the North Point Wet Weather Facility potentially increased the volume of Northshore CSDs on December 31 by approximately 4%. Violation None Report SF-SE Water Pollution Control Plant, N-Point & Bayside 392750 R2-2013-0029 N
1115322 04/08/2022 Unauthorized Discharge Discharged approximately 55 gallons of hydraulic fluid from one of the Division Street Combined Sewer Discharge (CSD) Outfall gates (gate #5). The cause of the spill is believed to be the failure of two hydraulic position sensors associated with the Division Street CSD Outfall. Notified of an issue via control system alarm on 4/7, but did not notice an oil sheen on receiving water until 4/8.
