NCO034304 111 121 18/07/24 1 17 18 ICI Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The Inspector, Linda Wiggs met onsite with Gary Kuykendall (ORC). Flow proportional sampling is required by the permit. The sampling taking place is not performed properly, nor is it below all treatment units. The plant was high in solids. ORC stated Carter Septic had pumped 2 weeks ago. Pumping/solids removal is generally every two months in summer and once during winter months. Wasting is generally 15 minutes/day (concrete plant) and 20 minutes/2-3 days (steel plant). The settleable solids varied between 75-90% and the blankets were elevated between 6-11'. The chlorine contact chamber had a blanket at 1'. The chamber had floating sludge leaving the plant. The Inspector had the ORC pump down the chlorine contact chamber and waste from clarifiers while onsite. Solids management was discussed. Documenting process controls to track solids management as well as increased solids removal is warranted. Flow surges were also discussed. An EQ tank is a component; however, the plant still has intervals of high flow readings. For example, June 2018 had 15 days at or over permitted flow of 0.05 MGD.
