1144741 05/15/2025 Unauthorized Discharge 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 Violation None Report City of Modesto RWRF - Sutter Campus/City of Modesto RWRF - Jenning Campus 147127 99-112 Y
1144740 04/23/2025 Unauthorized Discharge 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 Violation N Report City of Modesto RWRF - Sutter Campus/City of Modesto RWRF - Jenning Campus 147127 99-112 Y
