The eSMR does not include a required result for Sodium at location CAN-SEG for the week of July 28, 2025. City staff were notified by contract lab staff from Alpha Analytical on August 12, 2025, that the sample collected and sent to the lab could not be properly analyzed as the sample was taken in a bottle containing the wrong preservative. |
The City of Modesto takes its regulatory compliance seriously and has taken steps to prevent future sampling errors. City operations and laboratory staff have all been coached on the importance of attention to detail in sampling, sample receiving, and sample relinquishing. The City does not anticipate this will be a reoccurring issue. |

On 15 May 2025, the Discharger reported that a temporary pump transferring primary treated domestic sewage between sewer lines failed due to a hose fitting disconnection, resulting in a spill of approximately 170,500 gallons. The pump, operating without hydraulic assist, leaked sewage onto the sludge drying beds, access roads, the riverbank, and into the Tuolumne River. According to the Discharger’s visual inspections, approximately 1% of the spill approximately 1,705 gallons reached the Tuolumne River. Most of the spill was contained by damming with dirt and rocks. Most sewage remained within the facility's sludge drying beds, minimizing offsite impact. This spill is related to CanSeg line repairs listed as listed above. This spill constitutes a violation of Discharge Prohibition A.2 |

According to Discharge Prohibitions A.2 of the WDRs, discharge of treated wastewater at a location or in a manner different from that described in the Order is prohibited. On 23 April 2025, the Discharger reported a 62-gallon spill from a manhole on the CanSeg line at Hatch Rd and Rancho Encantado. According to the Discharger, this line was used temporarily to bypass the domestic line during repairs for CanSeg line. The leak likely occurred during a flow peak late on 22 April 2025, which ceased before staff arrived and minimal flow reached a nearby storm drain, and wastewater remained contained. This spill constitutes a violation of Discharge Prohibition A.2 |

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. |

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. |
