Order Conditions |
The discharge of untreated process water from Sediment Trap 3 affected water quality in Swiss Creek during RWQCB inspection was observed on October 11, 2024. The RWQCB observed sediment in the tributary from Discharge Point 004 and foam and aquatic growth downstream of the tributary that was not visible upstream. Permit receiving water limitations V.A.1 and V.A.4 prohibit discharges from causing floating materials (foams, scum), bottom deposits, and aquatic growths that affect the beneficial uses of receiving waters. |

Deficient Monitoring |
On November 25, SCQ collected an acute toxicity sample at EFF-004, which followed the proper sampling technique and occurred under normal ATS operating conditions. On November 26, 2024, discharge ceased from EFF-004. On November 27, SCQ was notified by the laboratory via email, that it did not conduct the acute toxicity test due to using the wrong sample for testing. Therefore, the original sample extended beyond the 36-hour hold time and the acute toxicity test could not be completed. |

Deficient Monitoring |
The NPDES permit requires WQCP to monitor pH at the E-001 site. Since June 1, 2023, WQCP has implemented real-time pH monitoring at E-001 using a HACH Digital pH sensor (model #: DPD1P1), with data transmitted to SCADA via the HACH controller (model#: SC200). In November 2024, technical issues with the controller caused data transmission failures on 7 days, resulting in 3 days with data gaps more than 60 minutes and the total time of data gaps during the calendar month more than 7 hours and 26 minutes. These conditions are specified for compliance determinations using a continuous monitor (Order No. R2-2019-0021, Table 4, footnote 1). Despite the missing data, the effluent pH remained within the compliance range of 6-9 s.u., as confirmed by the upstream pH analyzer, located after the aeration basins and before the secondary clarifiers. The upstream analyzer typically records pH values similar to those measured at E-001 and demonstrated consistent compliance within the 6.0¿9.0 range throughout the month. A thorough investigation was conducted by the Lead Plant Mechanic Kenneth de Leon and Lead Operator Ryan Estrada. Hardware, communication, environmental, and SCADA-related causes were ruled out (see table below). However, software glitches or bugs remain a possible, undetermined factor. It was observed that when the analyzer sent a warning signal to the controller, data transmission between the controller and SCADA is paused. |
