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. |

Irvine Ranch Water District (IRWD) operates the Los Aliso Water Reclamation Plant (LAWRP) seasonally between recycled water operations and discharge to the ocean depending on demand for recycled water and reservoir storage capacity. The agency had an unusual need to divert LAWRP from recycled water operations to ocean discharge on a short term temporary 4-day period that fell between two different weeks. On Thursday October 3rd the LAWRP operations switched from recycling operations to ocean discharge and on Monday the process reverted to recycled water operations. The regulatory requirements are different for each operation. Because of the short duration of the process switch and the fact that it occurred over two different sampling weeks, there was some miscommunication about what needed to be sampled for the ocean discharge via the South Orange County Water Authority (SOCWA). Between October 4th and October 7, a composite sample for LAWRP influent was collected on Friday and Monday. We normally do not run the weekly influent cBOD or BOD on Fridays or Mondays and failed to communicate the need to adjust sampling requirements. Influent cBOD and BOD is specified as a weekly test on the LAWRP chain of custody forms. The IRWD Water Quality Laboratory was not aware of the switch in point of use/discharge from LAWRP, and staff assumed the test had been completed the day before, so they did not repeat when the request came through to do it again. |
IRWD has completed a root cause analysis and determined that the monitoring and laboratory staff need to build a better communication chain for infrequent changes in operation. We have worked together to update the Chain of Custody forms and Standard Operating Procedures to prevent a recurrence of missed samples under a temporary change of the point of use or discharge. IRWD has reviewed all the laboratory data and have determined that the weight of evidence indicates that the LAWRP was running normally during the time of the temporary discharge. |
