Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) On the day of inspection there was some sludge on the ground throughout the plant and in the area adjacent to the WWTP leading to the East Prong of Slocum creek. These solids came from a bypass that occurred on March 2, 2024. During the inspection on March 5, 2024 plant personnel was cleaning up the sludge inside the fence but no effort had been made by the City to clean up the solids leading to the East Prong of Slocum creek. Influent sampler is on constant time and constant volume with a sample taken every 20 minutes. On the day of inspection sampler temperature was 6.5 degrees C. The facility was reminded that sampler temperature must be below 6 degrees C. The bar screen and grit chamber are currently bypassed due to influent manhole replacement which is projected to be completed by March 8, 2024. The bar screen and grit chamber will be placed back online once construction is completed. MLSS in the aeration basin is around 6,500 mg/I with the sludge blankets in both Clarifiers around 6'. MLSS concentrations appear to be elevated in the system and the MLSS levels need to be at a more manageable level to prevent washout during high flow events. Lewis Farms land applies the sludge for the Havelock WWTP. Lewis Farms applied 205.52 dry metric tons of sludge for the City of Havelock during 2023. The facility was judged to be Non -Compliant.
