Chloride Other limit is 100 mg/L and reported value was 104 mg/L at EFF-001. |
Per Section 4.1.1 of the WDR, the 3-month rolling average waste load allocation (WLA) based final effluent chloride limitation set forth in Resolution R4-2014-010 became effective after startup of the UV and MF/RO (i.e., Advanced Water Treatment Facility, AWTF) projects at the Valencia WRP and expiration of a time schedule order (TSO). By November 2023, the UV and AWTF projects started up and TSO expired. Thereafter, the WLA-based final limitation became applicable. However, at the request of Regional Board staff on January 30, 2024, who have a different interpretation of the WDR, the limit was recalculated and compliance assessed using two-month average for December 2023. Based on the plain language of the WDR, the Sanitation District believes reporting compliance with this limitation should not occur until January 2024, when three months of flow and chloride data post AWTF startup are available to calculate the limitation, as specifically prescribed in the WDR. In December, the monthly average effluent chloride was 104 mg/L which exceeds the final effluent chloride limit following Regional Board's interpretation, 100 mg/L. Furthermore, the Sanitation District entered a 30-day testing and adjusting period, as documented in the Operations Plan submitted to the Regional Board on October 12, 2023, pursuant to the requirements in Water Code section 13385(j)(1)(D), which states that mandatory minimum penalties (MMPs) may not apply when a wastewater treatment unit is undergoing a 30-day period of adjusting or testing and certain conditions are met. The monitoring results and details on process operations during the period were summarized and submitted to the Regional Board on December 29, 2023, and a revised report on February 23, 2024. As such, the Sanitation District respectfully requests that MMPs not be applied to the December 2023 exceedance, which include data from the testing and adjusting period in November. |

Per Section 4.1.1 of the WDR, the 3-month rolling average waste load allocation (WLA) based final effluent chloride limitation set forth in Resolution R4-2014-010 became effective after startup of the UV and MF/RO (i.e., Advanced Water Treatment Facility, AWTF) projects at the Valencia WRP and expiration of a time schedule order (TSO). By November 2023, the UV and AWTF projects started up and TSO expired. Thereafter, the WLA-based final limitation became applicable. However, at the request of Regional Board staff on January 30, 2024, who have a different interpretation of the WDR, the limit was recalculated and compliance assessed using one-month average for November 2023. Based on the plain language of the WDR, the Sanitation District believes reporting compliance with this limitation should not occur until January 2024, when three months of flow and chloride data post AWTF startup are available to calculate the limitation, as specifically prescribed in the WDR. In November, the monthly average effluent chloride was 104 mg/L which exceeds the final effluent chloride limit following Regional Board's interpretation, 98.3 mg/L. Furthermore, the Sanitation District entered a 30-day testing and adjusting period, as documented in the Operations Plan submitted to the Regional Board on October 12, 2023, pursuant to the requirements in Water Code section 13385(j)(1)(D), which states that mandatory minimum penalties (MMPs) may not apply when a wastewater treatment unit is undergoing a 30-day period of adjusting or testing and certain conditions are met.

Chloride Other limit is 100 mg/L and reported value was 103 mg/L at EFF-001. |
Per Section 4.1.1.a of the WDR, the chloride effluent limit for the Valencia WRP is 100 mg/L as a 3-month rolling average. On May 9, 2019, the Regional Board adopted Time Schedule Order (TSO) R4-2019-0055 and on December 31, 2020, July 8, 2021, and December 8, 2022, adopted amended TSOs, R4-2019-0055-A01, R4-2019-0055-A02, and R4-2019-0056-A03, respectively, which grant additional time for the construction of facilities that will enable compliance with this limit. The TSOs are separate enforcement orders that do not modify the existing NPDES permit but do exempt the Sanitation District from mandatory minimum penalties (MMPs) for violations of the chloride limit as long as the TSO requirements are fully met. In October, the effluent chloride result was 102 mg/L with a 3-month rolling average of 103 mg/L, which exceeds the NPDES permit limit. The Sanitation District was in full compliance with the TSO; therefore, MMPs are not applicable. |

Per Section 4.1 of the MRP, continuous monitoring of total chlorine residual shall serve as a trigger for increased grab sampling for total chlorine residual excursions of up to 0.3 mg/L lasting more than 15 minutes. On November 1, the UV system was shutdown and all effluent flow was routed to the chlorine contact tanks (CCTs) for disinfection. During the transition, the metered final effluent total chlorine residual was between 0.1 and 0.3 mg/L for approximately 21 minutes which triggered grab sampling. A sample was collected; however, analysis of the grab sample did not follow analytical method protocol and, as a result, the non-detect result was not reportable. Despite this, sodium bisulfite, the dechlorination chemical, was dosed more than the stoichiometric amount needed to fully dechlorinate the effluent; therefore, the effluent was fully dechlorinated. To prevent this issue from re-occurring, the Sanitation District plans to implement procedures to ensure sample collection and analysis follow analytical method protocol. |

Per Section IV.A.1.a of the WDR, the chloride effluent limit for the Valencia WRP is 100 mg/L as a 3-month rolling average. On May 9, 2019, the Regional Board adopted Time Schedule Order (TSO) R4-2019-0055 and on December 31, 2020 and July 8, 2021 adopted amended TSOs, R4-2019-0055-A01 and R4-2019-0055-A02, respectively, which grant additional time for the construction of facilities that will enable compliance with this limit. The TSOs are separate enforcement orders that do not modify the existing NPDES permit but do exempt the Sanitation District from mandatory minimum penalties (MMPs) for violations of the chloride limit as long as the TSO requirements are fully met. In June, the effluent chloride result was 118 mg/L with a 3-month rolling average of 121 mg/L, which exceeds the NPDES permit limit. The Sanitation District was in full compliance with the TSO; therefore, MMPs are not applicable. |

Per Section VIII.A.1¬ of the MRP, receiving water samples shall be analyzed monthly for MBAS. Analytical results of samples collected from receiving water stations RSW-001U (R-C), RSW-002D (R-D) and RSW-003D (R-E) on May 3 are invalid due to data integrity issues. Make-up samples were collected in June and results will be reported in the June report. Corrective actions to prevent this from recurring include: 1) purchase and implementation of a spectrophotometer that has a reading log and can directly and electronically transfer results to the data management system to assure analytical results are accurately recorded, 2) routine review of analysts¿ adherence to laboratory Standard Operating Procedures (SOPs), and 3) additional staff assigned to oversee laboratory activities. |

Per Section IV.A. of the MRP, effluent samples shall be analyzed quarterly for oil and grease. An effluent sample was not collected or analyzed for oil and grease during the second quarter because this sample event was not transitioned to the new UV effluent monitoring location. On March 1 the Valencia WRP began discharging UV effluent directly to the river. As a result, the Sanitation District transitioned the EFF-001 monitoring location to collect UV effluent samples; however, Sanitation District staff missed transitioning the oil and grease sample. A make-up sample will be collected as soon as possible. To prevent reoccurrence, the sample location for effluent oil and grease samples was relocated to collect samples downstream of the UV disinfection process. |
