1141698 02/04/2025 DMON On February 2, 2025, in preparation for the pending rain events, CMSA staff increased the flow weighted pulse count on a 24-hour composite sampler from 15 pulses to 30 pulses. Historical blending conditions due to rain events result in total flow conditions of 30-60 MG. However, on February 4, 2025, during a storm event, CMSA experienced significantly elevated blending flows of 84.8 million gallons. During this sample event, the flow weighted composite sample collected samples from 00:00 to 13:49. This composite sample collection does not meet the 24-hour Composite Sample requirements outlined in CMSA¿s NPDES Permit Order #R2-2023-006, Attachment G, Section 8.3, which resulted in a non-representative Blended Effluent (EFF-002b) sample collection. The Total suspended solids (TSS) result was not reported for this February 4, 2025. A CMSA corrective action has since been addressed with CMSA staff whereby CMSA staff will increase the flow weighted pulse sampler count from 15 to 45 pulses. This will effectively mitigate all future flow rates of 60-120 MGD. Additionally, CMSA staff are updating the CMSAL A SOP-011, Rev. 003 to reflect this update and will conduct a SOP update training event to ensure effective implementation of this update.
