1126577 03/31/2024 DMON Missed some of the required monitoring for the three days of discharge at EFF-002. The missed samples were weekly E. coli and monthly nitrogen species and metals. Missed some of the required monitoring for the three days of discharge at EFF-002. The missed samples were weekly E. coli and monthly nitrogen species and metals. There was not enough water stored in the equalization basin to run EFF-002 for a longer duration. Operators were informed when discharge occurs, even for a short duration, the full monitoring schedule applies. Violation U eSMR
1114133 01/31/2023 Order Conditions TSS percent removal at EFF-002 was 70% this month. The reason is that the TSS influent concentration was very low (dilution from high I&I due to extreme rain events). So even though the effluent concentration was also low and met effluent limits, the difference between influent and effluent concentrations was not significant enough to meet the 85% threshold.

1112724 12/31/2022 CAT2 Dichlorobromomethane Monthly Average limit is 1.4 ug/L and reported value was 1.56 ug/L at EFF-001. The AMEL violation was due to an elevated DCBM result of 2.6 ug/L on 12/31/22. It is unclear what caused this elevated concentration on that day. Accelerated monitoring conducted in January showed lower levels that were in compliance with the AMEL. Violation U eSMR
