Deficient Monitoring |
During 04/27/25 the turbidity grab samples for both Effluent and Influent were not processed by the PLWTP laboratory (ELAP Cert. 2474); Therefore, the PLWTP daily monitoring during the mentioned date is not in compliance with the ¿Minimum Sampling Frequency¿ definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409; Table E-2. Influent and Emergency Connection Monitoring and Table E-4. Effluent Monitoring. The PLWTP monitoring for Benzidine is not in compliance with the ¿Minimum Sampling Frequency¿ definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409; Table E-2. Influent and Emergency Connection Monitoring and Table E-4. Effluent Monitoring. Due to the QC accuracy percent recoveries for the EPA 625.1 Base Neutral analysis for both 04/09/25 PLWTP Effluent and Influent were below the acceptance criteria stated in SOP ID 6144 revision 10 section 16.3.2, hence the results for the mentioned analyte are not reportable. |

Deficient Monitoring |
Due to a power outage at the PLWTP and an autosampler sensor malfunction, the composite effluent samples from the 03/30/25 and 03/31/25 collections may have been affected. The collected sample during 03/30/25 may differ from the composite sample definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409 Part 2. ¿ Glossary of Common Terms ¿Daily Discharge¿. The 03/30/2025 effluent composite sample was obtained from a combination of at least eight sample aliquots of at least 100 mL at periodic intervals during the time frame from 12:00 am to 09:30 am; therefore, the sample not necessarily reflects the plant¿s operating hours over a 24-hour period for the following analyses: Floatable solids, BOD, TDS, TSS_VSS. The 03/31/2025 effluent composite sample was obtained from a combination of at least eight sample aliquots of at least 100 mL at periodic intervals during the time frame from 12:00 am to 23:59 pm. Due to autosampler sensor malfunction it¿s possible that the effluent composite sample collected during 03/31/25 may differ from the ¿flow proportional¿ composite sample definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409 Part 2. ¿ Glossary of Common Terms ¿Daily Discharge¿; affecting the following analyses: Floatable solids, BOD, TDS, TSS_VSS. |

1. Due to the matrix sample nature the percent RPD value in batch 24341BOD55 was outside the method acceptance criteria stated on SOP (1467) BOD_WW_SED_SLDS Revision 10; Section 16.1.4; For the Biochemical Oxygen Demand (BOD) analysis of Effluent samples, collected on 12/04/24 and 12/05/24. The analytical batch was deemed non-reportable. Due to the nature of BOD testing, the sample could not be reanalyzed after the 5-day incubation period when results become known. Therefore, the permit BOD frequency requirements of 1/Day were not met. 2. Base Neutral analysis under EPA 625.1 results showed %RPD outside of criteria for Hexachlorocyclopentadiene. The results for effluent, effluent duplicate where all not-detected (ND). The Internal Check 1, Matrix Spike 1 and Matrix Spike duplicate were within acceptance recovery limits. Batch met accuracy but not precision criteria therefore, per QA criteria the results in SOP ID 6144 revision 10 section 16.8 and 16.9, the results for Hexachlorocyclopentadiene are not reportable. |

PLWTP experienced a power outage November 2-3, 2024 which affected effluent autosamplers. As a result of the outage, the autosamplers remained inoperable on November 3 - 4, 2024. Operations staff manually collected and composited 200 mL of both effluent and influent samples every 2 hours for 24 hours on November 3 ¿ 4, 2024; however the resulting composites were not flow proportioned as required by the permit. Analyses affected include BOD, TSS, VSS, TDS, and Floatables. |

TCDD Equivalents: PLR collected on 8/7/24 was outsourced and analyzed for Dioxins method 1613B. The laboratory report revealed the analytical batch internal check recovery for 2,3,7,8-TCDF was non-detect and the analyte was therefore deemed non-reportable. |
