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 Monitoring |
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 |
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. |

This is a new monitoring constituent, added in the 2021 permit. The WWTRP changed procedures so this sampling is not missed in the future. pH and temperature measurements are required daily, at monitoring location EFF-001, when discharging to the river. Operators missed this requirement during river discharge, from 1/11 to 1/14. Operators were made aware of the requirement and will record these values during future discharge events. |

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. |

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. |
