Deficient Monitoring |
During the week of Feb 8 our sump transfer pumps were broken at our D2 sanitary sewer, so the sewage had to be vacuumed out of the sump with a vacuum truck. Historically whenever this happened, we would offload the sewage in the vacuum truck at the other sanitary sewer sump (D1). In those cases, we would only sample at D1 since that one sample would be representative of the sewage from both locations. During that time, instead of offloading at the D1 sanitary sewer sump, the vacuum trucks offloaded at our pump station 1 oily sewer sump instead due to miscommunication. Because we thought that the D2 sewage was being offloaded at the D1 sanitary sewer sump, we only collected a sample at D1 that week and did not collect a sample at D2. We had full bleach injection flowing that whole week at the D2 sanitary sewer, and site staff noted that the bleach in the sump was 10mg/L using test strips, so we expect that the enterococcus was non-detect as usual during the week that we did not sample. |

Unauthorized Discharge |
?On June 1, 2025, an incident occurred in which float material from the Dissolved Air Floatation Tanks (DAFTS) that was on route to the ponds via the Primary Effluent Line, spilled into the Fish and Wildlife Service (FWS) Channel. Typically, primary effluent goes with the float to the ponds and keeps things moving. During this incident the primary effluent was diverted to a different line as well as the float. However, only the float was returned to the Primary Effluent Line initially. With only the float in the line it began to back up in the Primary Effluent Line until it overflowed. |
