1128968 05/31/2024 CAT1 Carbonaceous Biochemical Oxygen Demand (CBOD) (5-day @ 20 Deg. C) Monthly Average limit is 25 mg/L and reported value was 34 mg/L at EFF-001. Reactor project expected to be completed by the end of 2024. Violation U eSMR
1128967 05/11/2024 DMON For the week starting 5/5/2024 ending 5/11/2024: cBOD sampled on 5/8/2024 was sent to Alpha Analytical Lab for analysis. 5/9/2024 and 5/10/2024 cBOD samples were sent to CEL Analytical Lab for analysis. Alpha Analytical Lab reported cBOD as > 22mg/L. CEL Analytical lab invalidated the samples sent on 5/9/2024 and 5/10/2024. Therefore, we did not have a cBOD result for the week ending 5/11/2024. Spoke with both analytical labs and put in corrective actions to prevent future errors. Alpha Analytical will analyze additional dilutions and CEL analytical has modified their seed preparation.

Once Digester 1 is up and running at full capacity, as the primary digester, the load on digester 2 will be significantly reduced, allowing the secondary clarifier effluent to clear up.
