On December 5th, 2023, the CDP suffered a mechanical malfunction in its back wash system, causing plant effluent containing sludge to discolor the receiving waters. The CDP Laboratory collected and analyzed samples from the M-002 sampling point during the event. Results of those samples show that discoloration of receiving waters was the only permit violation. |
The CDP has corrected the mechanical back wash system malfunction, renovated the effluent Turbidity analyzer, and adjusted the SCADA system alarms. These modifications and adjustments were completed to assure continuous and reliable NTU readings. |

Discharge was notified by the outside laboratory that the Oil and Grease sample for analysis taken on 8/28/2023 to satisfy the M-001 NPDES sampling for the compliance week of 8/27/2023 to 9/2/2023 are to be considered estimated values. This is due to the laboratory reporting that Low recovery was observed for total oil and grease in the LCS/LCSD for the batch. No additional sample volume remained for re-extraction or re-analysis. |
The external laboratory is revalidating their extraction procedure and their Quality Control Standards, to prevent further occurrences of this type. During that time Weekly sample analysis has been deferred to another outside laboratory. |

Discharger was notified by the outside laboratory that the Oil and Grease sample for analysis taken on 8/14/2023 to satisfy the M-001 NPDES sampling for the compliance week of 8/13/2023 to 8/19/2023 was determined to be invalid. After total consumption of the sample volume, it was determined the LCS stock standard was invalid. Therefore, Oil and Grease results must be considered as estimated values due to missing positive control QC. |
The external laboratory is revalidating their extraction procedure and their Quality Control Standards, to prevent further occurrences of this type. During that time weekly sample analysis has been deferred to another outside laboratory. |

On August 3, 2023, a valve in CDP's backwash system suffered a mechanical malfunction, causing plant effluent containing untreated backwash water to discolor the receiving waters. The CDP Laboratory collected and analyzed samples from the M-002 sampling point during the event. Results of those samples show that discoloration of receiving waters was the only permit violation. |
The CDP has corrected the backwash system malfunction and implemented further monitoring efforts and alerts for operational oversight to more closely monitor and respond quickly if a similar type of valve malfunction occurs in the future. |

During the compliance week of 04/11/2021 to 04/17/2021 the CDP was scheduled for a maintenance shutdown. The maintenance shutdown was scheduled for 8:00PM on April 11th to 8:00PM on April 16th, The lab had scheduled to collect the samples after the plant was returned to normal operation on April 16th. Due to unforeseen circumstances the plant did not return to normal operation until April 18th, which is outside the compliance week. Therefore the lab was unable to collect the weekly sample a monitoring location M-001 for the compliance week beginning April 11th. The CDP was in normal operation for the period of 19 hours and and 42 minutes on 04/11/2021. During this operational time the CDP failed to collect the required weekly NPDES sampling. |
CDP Laboratory Director has developed a formal pre-shutdown sampling procedure. This procedure contains a checklist of required monitoring to conduct prior to forthcoming planned shutdowns. In order to eliminate a failure to conduct compliance monitoring in the event of schedule changes of unseen circumstances. |

Order Conditions |
On 8/23/2020 Discharger exceeded the maximum allowable intake of 299 MGD of seawater by 1.35 MGD due to the dilution flow values set within CDP''s SCADA system not properly accounting for the brine dilution provided by maintenance flow cycled through the plant. |
Upon identification of this oversight, the plant¿s SCADA system was immediately updated
to properly account for seawater that is cycled through the plant that contributes to the brine
dilution.. |

During the Q3 offshore monitoring conducted on August 29, 2019, a total of three rounds of monitoring occurred across the 16 offshore monitoring locations, weather and water conditions permitting, and twice across one offshore monitoring location E-30 (located 1,000 feet downcoast of the discharge channel and 2,000 feet offshore). The contractor conducting the monitoring inadvertently missed station E-30 in the first round of monitoring. |
The receiving water monitoring contractor has updated the QA/QC procedure to ensure offshore monitoring is conducted as specified in Order R9-2019-003 to the maximum extent practical, while taking into consideration conditions which could make sampling hazardous at monitoring locations. |

TCDD analysis for the CY19 Q3 reporting period was not conducted in accordance with Attachment E, Table E-4. Effluent Monitoring at M-001 when not Discharging Brine of the Order. While the CDP Operator collected the CY19 Q3 monitoring samples the Chain of Custody (COC) was not updated to include the new TCDD monitoring requirement. |
CDP Operator has revised the Quarterly Chain of Custody (COC) template to reflect monitoring conditions identified in Attachment E, Table E-4 Effluent Monitoring at M-001 when not Discharging Brine of the Order. CDP Laboratory Director has further reviewed NPDES monitoring requirements with the external laboratory to mitigate a reoccurrence. |
