CAT1 |
Carbonaceous Biochemical Oxygen Demand (CBOD) (5-day @ 20 Deg. C) Monthly Average limit is 25 mg/L and reported value was 31.5 mg/L at M-001C. |
Based on data from both before and after the event, the exceedance appears to have resulted from an unknown increase of cBOD and no other abnormal conditions were observed. There was no process upset, or accompanying data to suggest a cause of a plant upset or dumping upstream of the wastewater facility. This was identified as an anomaly, and no further action could be taken during this isolated occurrence. |

The R9-2022-0006 permit requires a monthly Oil and Grease grab sample from the LAWRP SOCWA Effluent (M-001C) monitoring location. LAWRP effluent switched from Region 8 recycled water Effluent to Region 9 SOCWA effluent on January 8th, 2025. When this transition occurred, there was a human error with scheduling these samples onto an internal sampling calendar, and the monthly sample was missed. |
Staff have updated the Chain of Custody to clearly identify monthly required samples for the R9-2022-0006 and ensure that monthly Oil and Grease sample is collected. An additional review of sampling requirements and samples collected prior to the month concluding has been implemented. And lastly, the Oil and Grease sample will be increased to twice a month for a period of 6-months to ensure the analyte is not missed, and to ensure the secondary review is established prior to returning to once a month. |

cBOD and TSS were not monitored daily on 5/4/2022 when there was flow. IRWD Regulatory Compliance Monitoring staff missed the May 4th composite sample of the secondary effluent to South Orange County Wastewater Authority (SOCWA) Region 9 Aliso Creek Ocean Outfall (ACOO). The composite sample was missed due to new staff and a misunderstanding during this atypical operational event. |
As corrective actions, IRWD staff has reviewed the SOCWA Region 9 permit sampling requirements with respect to operational days and is using this scenario as a case study for an improved work process training of regulatory monitoring requirements for atypical events. IRWD Regulatory Compliance staff have instructed IRWD field monitoring staff to document atypical activity onto the Chain of Custody so that we can have a clear record of what occurred for future review. |

While re-reviewing the submitted data this morning for the ACOO, we discovered that there was a missed sample weekly event at M-001B for dissolved oxygen. All other entities were sampling for D.O. during that week so please advise if we will need to withdraw the submitted CIWQS report, and add a deficiency for the weekly monitoring. As a reminder, we are sampling at each plant because the monitoring station at the outfall has been down. We have the monitoring station scheduled in our capital program and should have a unified sampling location soon. - Amber Baylor |

On June 10, 2021, the sewage sludge force main between the South Orange County Wastewater Authority¿s (SOCWA¿s) Coastal Treatment Plan (CTP) and the Regional Treatment Plant experienced a pipeline failure resulting in a spill of non-chlorinated sewage sludge within the Aliso and Woods Canyons Wilderness Park (AWCWP) (Figure 1). The spill was situated along a dirt maintenance road off Alicia Parkway on the east side of Aliso Creek; the road is intended to provide the dual purpose of providing access to existing sewer and wastewater infrastructure as well as providing trail use to those who recreate in the AWCWP (Figure 2). The pipeline leak was repaired, and the spill was contained on the same day. A total spill volume of approximately 1,920 gallons of sewage sludge was released, cleaned up, and disposed of properly offsite. |
