Order Conditions |
The Discharger violated the UV system operating specification for UV dose contained in the WDRs/NOA, as listed in Table C. The Discharger stated that they lowered the target dose to 80 mJ/cm2 according to new MBR process guidelines rather than maintaining permit requirement of 100 mJ/cm2. The Discharger increased the target dose back to 105 mJ/cm2 when they realized the permit limit had not been amended. After returning to the higher target dose, the Discharger noted average dose was still dipping below the setpoint and identified several UVI sensors that were causing the dose to be calculated artificially low. The Discharger replaced the faulty sensors in July 2024 and UVI dose calculations are now above the 100 mJ/cm2 permit requirement. |

Deficient Monitoring |
The Discharger stated the missing temperature results at EFF-002 during May 2024 were due to a miscommunication between the programmable logic controller (PLC) and the supervisory control and data acquisition (SCADA) system. The miscommunication was corrected on 29 May 2024 and EFF-002 temperature monitoring and reporting returned to normal operation. |

Second required chronic toxicity monitoring event in 2023 did not occur. The Discharger stated that the late Fourth Quarter 2023 and Annual 2023 SMR submittals were due to internal production challenges at the Facility coupled with the new responsibilities for compliance with the WDRs. The Discharger stated that chronic toxicity monitoring will be conducted in early- to mid-August 2024 to account for the missed 2023 event. |

Order Conditions |
The Discharger violated the Filtration System Operating Specifications for turbidity contained in the WDRs, as shown in Table C. The Discharger reported exceedances of the maximum daily average value of 2 Nephelometric Turbidity Units (NTU) on seven days in late-April 2024. The Discharger suspects the increased turbidity was caused by the seasonal change in temperature and consequent effect on the Facility¿s biological treatment process. Turbidity was restored to levels compliant with the WDRs on 26 April 2024. |

Deficient Monitoring |
The plant was experiencing high turbidity and the plant was put on diversion for most of the day. The pH and temperature were not measured during the approximate 40-minute window when the laboratory analyst was present due to a misunderstanding. The laboratory analyst thought that the plant was going to be discharging the rest of the day but the turbidity was high that the plant operator on site had to put the plant on diversion into the following morning. |
