Settleable Solids Monthly Average limit is 1.0 ml/L and reported value was 1.4 ml/L at EFF-001B. |
On February 19, 2024, the Santa Barbara area experienced a storm event delivering 3.06 inches of rain. As a result of the storm, instantaneous confluent flows swelled up to 34.09 MGD for over 12 hours producing a total effluent flow of 22.91 MGD, exceeding the design peak flow of 19 MGD. Wastewater staff put all available primary, aeration, and secondary tanks in service through the rainstorm to compensate for high flows. The City is actively working on improving the collection system capacity through capital improvement projects. The City is also conducting an Infiltration and Inflow (I&I) assessment, which will help identify potential sources of I&I within the City to better plan for future projects and coordinate with the on-going Sewer Lateral Inspection Program to encourage rehabilitation of private sewer laterals. |

On 11/16/23 at 11:28am while performing preventive maintenance on the recycled water distribution chlorine analyzers, a valving error occurred causing the Influent to the Chlorine Contact Basin to be analyzed instead of Recycled Water Distribution sample. |
On 11/17/23 at 9:51am the valving error was corrected and chlorine analyzers were reading correctly. Documentation was updated and training was held for Operations staff on proper valving procedures. The piping to the recycled water sample point was recently replaced as part of the Distribution Pump Station Upgrades project and had not not painted with identification yet.

Total Suspended Solids (TSS) Daily Maximum limit is 8260 lb/day and reported value was 9079.1 lb/day at EFF-001B. |
On January 9, 2023, the Santa Barbara area experienced a 25 year storm event delivering 5.10 inches of rain to the treatment facility. As a result of the storm, instantaneous influent flows swelled to 36.78 MGD for over 12 hours with a total effluent flow of 23.77 MGD. The final effluent total suspended solids (TSS) was elevated as well at 45.8mg/L. The high flows and high TSS value resulted in a violation of lbs/day of total suspended solids discharged from the treatment facility. Wastewater staff put all available primary, aeration, and secondary tanks in service through the rainstorm to compensate for high flows. The City is actively working on improving the collection system capacity through capital improvement projects.

Total Coliform on RCY-001 must be analyzed at a daily frequency on a grab sample. Sample invalidated on 10/11/22. Deficient monitoring violation occurred due the lack of a valid sample result. Staff invalidated the sample due to organic and inorganic fouling in the sample line and tubing. The fouling was only occurring at the sample location and the sample was not representative of the water quality in the recycled water distribution system |
Operations and Lab staff were given refresher training on proper sampling techniques and a preventative maintenance task has been created and scheduled to regularly flush sample lines and replace tubing. |

Deficient Monitoring of multiple parameters and multiple locations.
Continuous monitoring was lost due to the data servers losing power for approximately 1 hour and 27 minutes on March 11, 2022. Real-time SCADA system operation, including online analyzers, flow monitors, and alarm handling, was unaffected but no historical data was stored. Parameters affected include: Influent pH, Influent Flow, Effluent Flow, Outfall Residual Chlorine (Monitoring location EFF-001A and M-001), Commingled Effluent pH, Recycled Water Chlorine Residual, Recycled Water Flow, Recycled Water Filtrate Turbidity from 3/11/2022 21:50 to 23:17. Flow totalizer data is also stored locally at the PLCs (Programmable Logic Controllers) in the facility so daily total values were unaffected. The loss of power was caused by the main electrical breaker supplying the administration building tripping and the UPS (Uninterruptible Power Supply) providing back up power to the data servers also failing simultaneously. Operations Staff were on-site monitoring the facility and did not report any other process related failures or exceedances. |
Staff bypassed the failed UPS and were able to restore power to the data servers from the emergency generator at 23:17 on March 11. The UPS is regularly maintained and the batteries were replaced on March 2nd however they failed and the batteries to the UPS were replaced again after the failure. The tripped electrical breaker was reset and its settings were adjusted by a licensed contractor on March 12th. A new monitoring trend screen was developed for the SCADA workstations that includes all the permitted continuous monitoring constituents and so data can be retrieved locally even if there are network or server failures. A facility wide electrical upgrade is in final design and is anticipated to start in Fiscal Year 2023. The electrical project will replace the breaker that tripped and provide for improved SCADA resiliency with upgrades like redundant server facilities and an upgraded SCADA network. |

Enterococci Monthly 90th% limit is 110 MPN/100 mL and reported value was 2419.2 MPN/100 mL at EFF-001A. |
Chlorine dose target in chlorine contact hamber was increased from 7 mg/L to 8 mg/L on 10/7 after getting results from first day of high enterococcus values. On 10/11 when enterococcus results remained high chlorine residual was again increased from 8 mg/L to 8.5 mg/L.
The staff suspects that Aquabac, a larvicide used for midge fly mitigation, may have
caused falsely high enterococcus results. Operations and laboratory staff found
research papers which identified a non-enterococcus bacterial component of Aquabac as a possible interference for the enterococcus test. Operations staff discontinued the use of Aquabac. |
