Order Conditions |
According to WDRs R5-2022-0006-02, Provision IX.C.2.b, the numeric toxicity monitoring trigger for initiating accelerated monitoring is >1 TU. This trigger is not an effluent limitation but rather a threshold that requires the Discharger to begin accelerated monitoring. In the Fourth Quarter of 2023, the chronic toxicity test for Ceriodaphnia dubia exceeded the numeric trigger of 1 TUc, with reported results at <1.3 TUc. However, the Discharger did not initiate accelerated monitoring, which constitutes a violation of the order condition. Accelerated monitoring contains conducting two additional chronic toxicity tests on the species that exceeded the trigger of 1 TUc, using a 6-week median to evaluate compliance. If the 6-week median exceeds 1.3 TUc (as 100/EC25 or 100/IC25) and the percent effect is greater than 25 percent at 100 percent effluent, the Discharger must demonstrate to the satisfaction of the Executive Officer that the discharge is not causing chronic toxicity in the receiving water to maintain coverage under this Order. Failure to initiate accelerated monitoring is a violation of the WDRs. |

For the Fourth Quarter of 2023, however, the Discharger only reported a single data point for October, without specifying the exact days of discharge to surface water. This constitutes a violation of the Monitoring and Reporting Program (MRP). The following violations of the Monitoring and Reporting Program (MRP) occurred: |

Unauthorized Discharge |
A release occurred on the Aerojet GET pipeline near extraction well 4768. Aerojet estimated that the release lasted about 6 days at a flow rate of approximately 150 gallons per minute. Aerojet believes the release started on July 11; however, the exact release start date is unknown. The release reached Alder Creek, which flows into the American River. The pipeline that released this water conveys untreated groundwater from multiple extraction wells, so the contaminant concentrations in the discharged water can only be estimated based on individual extraction well flow rates and sample results. Aerojet provided the following total mass estimates for this accidental discharge: 3 grams NDMA, 32 grams TCE, and 13 grams perchlorate. |

Board staff received several odor complaints regarding the Sutter Plant in 2023 and 2024. During the inspection, Board staff investigated the area from which the complaints originated, spanning from Ustick Rd to Carter Ave and continuing through Carter Ave to Dallas St. While walking through this area, the odor was particularly noticeable, especially at the intersections of Ustick Rd and Carter Ave, as well as Carter Ave and Bollinger Ct. According to the Discharger, efforts are actively underway to identify and eliminate the source of the odor. The Discharger mentioned during the inspection that it is working with its consultant to develop a workplan that will identify the source of the odor and outline recommendations to eliminate it. According to WDRs 99-112 Provision B.6, ?objectionable odor originating at this facility shall not be perceivable beyond the limits of the disposal areas, wastewater transmission lines, or property owned by the Discharger.? Additionally, WDRs R5-2017-0085-002 Provision VII.C.4.c.v requires that objectionable odors shall not be perceivable beyond the limits of the facility. Since Board staff identified objectionable odors outside the Facility?s boundaries during the inspection, in violation of WDRs 99-112 and WDRs R5-2017-0085-002. |

Order Conditions |
During the inspection, it was noted that the refrigerator of the influent composite sampler was not functioning, Board staff noted that the internal temperature of the influent composite sampler was reading 10°C. WDRs Standard Provision III.B requires the Discharger to conduct sampling in accordance with 40 C.F.R. Part 136, which specifies a sample preservation temperature of 4 degrees Celsius plus or minus 2 degrees for proper preservation. Since the influent composite sampler is not maintained within the required temperature range, it does not meet sample preservation requirements, in violation of Standard Provision III.B. |

Surface Water |
According to WDRs Provision VIII.A.5, discharge is prohibited if it causes discoloration that leads to a nuisance or adversely affects the beneficial uses of the Receiving Water. The Discharger reported on 20 February 2023 that an unspecified amount of petroleum coke dust was accidentally released into the San Joaquin River during loading operations. This release resulted in a black sheen stretching approximately 200 feet down the channel, identified as petroleum coke dust. To mitigate the situation, the Discharger promptly ceased loading operations and initiated the addition of water to the petroleum coke to prevent further dust contamination of the waterway. This incident constitutes a violation of the WDRs. |

The eSMR is missing a required pH grab result from location EFF-001B on February 10, 2023. Operations staff in charge of samples on February 10th believed the plant to be in full bypass and not discharging to receiving water. This lead the operator collecting samples to not take the grab pH sample at location EFF-001B required by the permit. |

Deficient Reporting |
Acute Toxicity Sampling was collected by Ironhouse Staff and relinquished to the FGL Lab Courier on February 7, 2023 at 1350 hours. Subsequently the sample was relinquished several more times prior to being received by ABC Labs on February 7, 2023 at 1700 hours. Apparently a janitor accepted delivery of the sample after normal business hours, thus preventing the analysis from being completed within a normal hold time. Ironhouse staff were notified of the error on March 14, 2023. Therefore, resampling could not be completed within the required monitoring period and no results were reported. |

Currently the Discharger is using a temporary centrifuge press which is located east of anaerobic digesters building to dewater biosoilds. During the inspection, biosoilds were observed on the ground around the temporary centrifuge press, which may cause adverse impacts to the groundwater. This is a violation of WDRs Provision VI.A.2.f, which requires the Discharger to take all reasonable steps to minimize any adverse impacts to waters of the State. Board staff recommends that the centrifuge press to be moved on to a concreate pad and the dewatering process to be conducted in a manner that minimizes spill and leachate formation |

On 23 September 2021, the Discharger reported that at approximately 2:30 PM while pumping raw wastewater from the clarifier to fill digester #1, the hose connection from the pump to the digester separated allowing the wastewater to spill on the Facility?s ground. According to the Discharger some of the wastewater was absorbed into the grass area around the clarifiers and most of the wastewater made it to the overflow basin and drying bed #1, all the spill water was contained in the Facility?s ground. The Discharger estimated that a total of 375,000 gallons of wastewater was spilled during this incident. |

On 1 July 2021, the Discharger reported that one of its operation staff mistakenly opened a valve (DRY-SG9) at the Dryden Box Influent Structure, believing it to be necessary to divert cannery segregation water to the Pumping Plant #3. Instead, the valve was for the emergency diversion structure with the Dryden influent structure (distribution box for cannery segregation and domestic flows). Because of this the domestic wastewater mixed with the cannery segregation water and flow in to Pumping Plant #3 and ultimately discharged to the Jennings Ranch. Once the incident was discovered by the Discharger it immediately closed valve DRY-SG9. According to the Discharger, approximately 3 million gallons of domestic wastewater was sent, and land applied to the Jennings Ranch. |

On 16 June 2021, the Discharger reported that a partially treated wastewater used for irrigation spilled to into the slough adjacent to Filed #16. According to the Discharger, due to an error the operator released more water than originally agreed upon. As result, the partially treated wastewater filled the filed up to the berm and entering gopher holes and exiting holes on the opposite side of the dirt road and then flowing into the slough. Approximately a total of 28,500 gallons of partially treated water discharged into the slough. |

According to MRP Provision IX.D.1, from December 2020 through March 2021 the Discharger must conduct monthly effluent and receiving water characterization sampling, regardless of a discharge to Angels creek. However, the Discharger failed to conduct effluent and receiving water characterization. The Discharger was under the impression that no sampling was required when not discharging to surface water. In order to have sufficient data for permit renewal, please conduct monthly effluent and receiving water characterization sampling as required in the permit. |

The eSMR does not include required weekly results for conductivity at locations DMC-001 and DMC-002 for the week of April 4, 2021. Though the required samples were collected, an error within the laboratory caused them to be discarded before analysis. Discovery of the processing error did not occur until after the week had ended, making resample impossible. |

Order Conditions |
During the inspection, Board staff observed that there is no leachate collection system for the drying pad area and during the precipitation events the runoff from the area would be discharged directly through the stormwater collection ditches to San Andreas Creek. Discharging stormwater runoff from the drying pads, without treatment, adversely affects water of US and is violation of WDRs Provision VI.A.2.f. |

Order Conditions |
The WDRs Provisions VI.C.4.a.III (b) and (c) require the Discharger to manage its ponds to prevent any excessive weed overgrowth, and vegetation and debris accumulation in ponds. During the inspection it was observed that pond B was completely covered with vegetation and debris, and pond D had significant amount of vegetation. Because excessive vegetation can cause nuisance conditions, decrease Facility¿s storage capacity, and may promote breeding of mosquitoes, presence of excessive vegetation is a violation of the WDRs. Therefore, the Discharger must develop a Best Management Practices (BMP) plan to eliminate or reduce vegetation and debris accumulation in the ponds. |
