Deficient Monitoring |
On February 2, 2025, in preparation for the pending rain events, CMSA staff increased the flow weighted pulse count on a 24-hour composite sampler from 15 pulses to 30 pulses. Historical blending conditions due to rain events result in total flow conditions of 30-60 MG. However, on February 4, 2025, during a storm event, CMSA experienced significantly elevated blending flows of 84.8 million gallons. During this sample event, the flow weighted composite sample collected samples from 00:00 to 13:49. This composite sample collection does not meet the 24-hour Composite Sample requirements outlined in CMSA¿s NPDES Permit Order #R2-2023-006, Attachment G, Section 8.3, which resulted in a non-representative Blended Effluent (EFF-002b) sample collection. The Total suspended solids (TSS) result was not reported for this February 4, 2025. |

Deficient Monitoring |
Instances of deficient monitoring are: Week of 1/5-1/11: INF-001 BOD and TSS and EFF-001D BOD, TSS, and E. coli were not collected. These are required weekly when discharging to the river. Week of 1/12-1/18: EFF-001D TSS was not collected. The CCB had to be shut off on 1/14 due to pond levels, and that was before staff were able to grab the weekly E. coli, BOD, and TSS from the CCB effluent. However, BOD and E. Coli samples were collected later in the week, on 1/16, from the effluent at the new plant, but TSS was missed. Week of 1/19-1/25: INF-001 TSS was not collected. Influent BOD and TSS are required weekly when discharging to the river. Influent BOD was sampled 1/23, but TSS was missed. EFF-001D TSS and E. coli were not collected. The weekly BOD sample was collected 1/23, but TSS and E. coli were missed that week. Week of 1/26-1/31: All samples were collected, but but the contract laboratory failed to analyze the EFF-001D TSS was sample. Correspondence from the lab is on file. Most of the missed monitoring was due to the transition to the upgraded plant and a change in sampling protocols. Operators were trained in the new protocols and sampling locations and these issues were corrected by the end of the month; unfortunately even when all the required sample collection was performed properly on the last week of January, the laboratory missed one of the required analyses. |

Deficient Reporting |
The analysis results for BOD samples (INF-001 and EFF-001) collected on July 7th are invalid because the tests failed the quality assurance and quality control (QA/QC) protocols for the test. Consequently, the District does not have the two valid BOD sample results required for the first week of July. The District reanalyzed the sample collected July 7th on July 13th. However, this test is beyond the acceptable hold time for BOD sampling. As such, these sample results are qualified in CIWQS as analyzed after the holding time expired. |

Deficient Monitoring |
The analysis results for the BOD samples collected on February 1st and 2nd are invalid because the tests failed the quality assurance and quality control (QA/QC) protocols for the test. Consequently, the District does not have the two BOD sample results required for the first week of February. The QA/QC failed because the Laboratory Control Samples (LCS) for the BOD samples collected on those two days were prepared with the incorrect standard. The sample results for the Ammonia samples collected on February 8th and 9th were analyzed outside of the normal hold times. |

Effluent total coliform and E. coli monitoring is required weekly at EFF-001D during periods of discharge to the Napa River; this sampling was missed this month. Effluent and influent BOD and TSS monitoring is required weekly at EFF-001D during periods of discharge to the Napa River; in January, four weekly samples should have been collected. Sampling was conducted, but not at the required frequency. Influent and effluent TSS monitoring was conducted once, as was influent BOD. Effluent BOD monitoring was conducted twice. pH measurements are required daily, at monitoring locations EFF-001 and EFF-001D, when discharging to the Napa River. Daily measurements were taken at EFF-001, but some were missed at EFF-001D. pH measurements at EFF-001D were not recorded on weekends and holidays this month (1/1-1/2, 1/7- 1/8, 1/14-1/16, 1/21-1/22). Effluent cyanide monitoring is required monthly at EFF-001 during periods of discharge to the Napa River; this sampling was missed this month. |

Deficient Monitoring |
The analysis results for BOD samples collected on January 4 and 6 were invalid because the tests failed the quality assurance and quality control (QA/QC) protocols for the test. Consequently, the District does not have the two BOD sample results required for the week of January 1st. District staff investigated the cause of the failed analysis and determined the QA/QC failure was related to the heavy storms that occurred during early January. The significant storms over-diluted the primary effluent used to seed the BOD. |

Unauthorized Discharge |
On Saturday, December 31, 2022, the District experienced extraordinarily high influent flows throughout its satellite collection systems and conveyance system as a result of the atmospheric river that hit the Bay Area. There was an overflow in the headworks area of the Delta Diablo Wastewater Treatment Plant (WWTP) located at 2500 Pittsburg Antioch Hwy in Antioch, CA. A portion of the overflow, consisting of wastewater that had been screened and underwent grit removal, may have reached a stormwater drainage canal to the east of the WWTP. Most of the overflow was contained onsite and sent through the WWTP for full treatment. The overflow started at 1715 and ended at 1830 (75 minutes) at the grit chamber. The total overflow volume is estimated at 84,375 gallons and the flow travelled to the west, north, and east of the overflow point and was mostly contained on the WWTP site where it will be returned through the system for full treatment (80,625 gallons). The portion of the overflow that may have reached receiving waters is estimated to be 3,750 gallons (50 gallons per minute for 75 minutes). The involved waterway was the Los Medanos Wasteway, a drainage canal running north to south along the east side of the WWTP. CalOES was notified of the unauthorized discharge. No receiving water sampling was conducted as river conditions were deemed unsafe for staff during the storm event. Observations of the receiving waters could not be made due to the discharge being diluted by inflow and infiltration and due to the saturation of the area due to the rainfall. |

Deficient Monitoring |
On May 28, 2022, a coliform sample was collected and analyzed by method SM 9221 B, C. The sample was collected at the Chlorine Contact Basin II (CCB II) location as specified in the SOP. However, CCB II was offline at the time of sampling, and therefore resulted in a deficient sampling event, as the sample collected was not representative of the flow at the time. Corrective action was initiated, and the sampling location was changed to the outfall of the final CCB in operation and prior to dechlorination. |

E. Coli sampling is required weekly, when discharging to the river. These analyses were requested on the Chain of Custody forms but were not performed by the City¿s contracted lab during the February discharge period. The City alerted the lab to the issue and they will provide the required analyses moving forward. pH and temperature measurements are required daily, at monitoring location EFF-001, when discharging to the river. Operators missed this required. They were made aware of the requirement and will record these values during future discharge events. On 2/16, while discharging to the river, operators missed a series of required at EFF-001D sampling, when discharging to the river. EFF-001D samples were collected on 2/17 instead, but by then discharge had stopped. Operators were made aware of the issue and EFF-001D samples will be collected on days of discharge in the future. |

Deficient Monitoring |
Copper sampling is required monthly when discharging to the river, but unfortunately staff did not request this analysis from the analytical laboratory. We don¿t foresee this being an issue moving forward; a sample was taken in January, as required, and results are pending. E. coli sampling is required weekly, when discharging to the river, at both EFF-001S and EFF-001T. Flow was produced at EFF-001S over a period of two weeks, from 12/15 to 12/28, and E. coli samples were collected on 12/17 and 12/24. Unfortunately, the lab analyzed the 12/17 for total coliform, instead of E. coli as requested on the Chain of Custody (COC) form. As such there is no E. Coli result to report for 12/17 at EFF-001S. The 12/24 result was non-detect, below the analytical detection level of 1 MPN/ 100mL. Flow was produced at EFF-001T over a period of three weeks, from 12/1 to 12/14 and again from 12/29 to 12/31. E. coli samples were collected weekly on 12/17, 12/24, and 12/30, and the analysis requested on the respective COC forms. Unfortunately, the lab failed to analyze for E. coli on all three occasions. Moving forward, we have alerted the lab to this issue and they assured us that all required analyses will be processed in the future. |

Deficient Monitoring |
Effluent E. coli monitoring is required weekly during periods of discharge to the Napa River; this sampling was not conducted until the final week of discharge, on 12/28. Unfortunately, even the 12/28 result is not available as the contract lab mistakenly returned fecal coliform results instead. Effluent samples were collected for BOD and TSS for the week of 12/19-12/25, but the contract lab has not provided the results at this time. Effluent pH and temperature results were not recorded on 12/9, 12/11, and 12/12. |

Deficient Monitoring |
Effluent samples were not analyzed for E.coli this month. E.coli monitoring is a new requirement in our 2021 permit and the chain of custody forms we were using had not been updated with the new requirements. This issue has been corrected and E.coli will be sampled moving forward. pH and temperature measurements are required daily, at monitoring location EFF-001, when discharging to the river. Operators missed this requirement. pH and temperature were recorded only at monitoring location EFF-001-D (disinfected effluent entering the pond). pH measurements are also required daily, at monitoring location EFF-001-D, when discharging to the river. Effluent samples were analyzed for pH and temperature was recorded on a weekly, instead of daily, frequency. Total coliform sampling is required weekly at EFF-001-D, when discharging to the river. Effluent was discharged to the river from 11/16 to 11/29 this month (over three calendar weeks). Operators missed this requirement for the third week of discharge. Influent BOD and TSS sampling are required weekly, when discharging to the river. Effluent was discharged to the river from 11/16 to 11/29 this month (over three calendar weeks). Operators missed this requirement for the second week and the third week of discharge. Monitoring training has been provided and all sampling will be collected in the future. |
