Violation N eSMR Lincoln City WWTF 456827 R5-2024-0024 Y 1141696 02/04/2025 Surface Water During Event #3, the turbidity increased from the upstream receiving water location (RSW-001; Delta King 29.1 NTU) to the downstream receiving water location (RSW-002; Miller Park 51.3 NTU) by greater than 20%, The turbidity decreased from the upstream receiving water location (RSW-003; Westin Boat Dock 40.5 NTU) to the downstream receiving water location (RSW-004; Zacharias Park 24.9 NTU), meeting receiving water limitations. It¿s important to note that RSW-004 (24.9 NTU), the furthest downstream, received water was lower than RSW-001 (29.1 NTU), further indicating that the CSS is not contributing to increased turbidity in the Sacramento River during CSO events. During CSO events in the past, receiving water limitations for turbidity have occasionally been exceeded. Previous evaluations have determined that turbidity can vary in the Sacramento River over the course of storm events, but the variability was not necessarily related to CSO events. Additionally, during prior turbidity self-reported violations, the Central Valley Regional Water Quality Control Board (CVRQCB) noted that the CSS was not the only contributor to turbidity during the event, and the Notice of Violation was reversed.
