1134395 12/31/2023 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. Violation N Report Lehigh Southwest Cement Company (f/k/a Calaveras Cement Company) 454583 R5-2022-0006-02 Y

1132755 07/11/2024 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.

The Discharger estimated that a total of 375,000 gallons of wastewater was spilled during this incident. Violation None Report Modesto WQCF WW Land Disposal (secondary trtmt) 147127 99-112 Y
1099618 08/11/2021 Order Conditions On 11 August 2021, the Discharger reported that a leak was discovered in cannery segregation line that runs between the Sutter Plant and the Jennings Plant. The leak was discovered coming up from the levee road and running into the drying bed at approximately 50 gallons per minute. The Discharger inspected and confirmed that the Tuolumne River side of the line is no leaking and no spill made it to the Tuolumne River. The Discharger estimated that a total of 10,000 gallons of wastewater was spilled during this incident. Violation None Report Modesto WQCF WW Land Disposal (secondary trtmt) 147127 99-112 Y
1099617 07/01/2021 Order Conditions 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.

1099616 06/16/2021 Order Conditions 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. Violation None Report Modesto WQCF WW Land Disposal (secondary trtmt) 147127 99-112 Y
1099615 05/11/2021 Order Conditions On 11 May 2021, the Discharger reported that an operator accidentally opened a winterizing valve on one of the tailwater pump stations that leads to the onsite slough. According to the Discharger, it recaptured the spill and returned it to the pond/irrigation system. Approximately a total of 6,300 gallons of water discharged and recaptured and returned to the Facility. Violation None Report Modesto WQCF WW Land Disposal (secondary trtmt) 147127 99-112 Y
