This was a follow up inspection to the August 2018 inspection. The chlorine contact chambers have not been repaired. A makeshift fence has been put up around the contact chambers to keep people from walking on them. This is an appropriate temporary measure, but not an adequate permanent measure. I have not received any information from Carolina Water Service with regards to a permanent solution to this structural deficiency. If CWS does not feel that the deteriorating concrete is a safety concern, please send our office an evaluation by an engineer assuring its current structural integrity. The wasting lines, air line to the digester, and skimmer for the clarifier have all been repaired. The screening areas should be kept cleaner as there were some rags strewn around the ground near the bar screens. NC0022900 17 (Cont.)

Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable Solids, pH, DO, Sludge Judge, and other that are applicable? The bar screen area did not have acceptable housekeeping. The rest of the plant looked fine as far as cleanliness. Comment: Bar Screens Yes No NA NE Type of bar screen a.Manual b.Mechanical Are the bars adequately screening debris? Is the screen free of excessive debris? Is disposal of screening in compliance? Is the unit in good condition? The bar screen areas should be kept cleaner.Comment: Aeration Basins Yes No NA NE Mode of operation Ext. Air Type of aeration system Diffused Is the basin free of dead spots? Are surface aerators and mixers operational? Are the diffusers operational? Is the foam the proper color for the treatment process? Does the foam cover less than 25% of the basin’s surface? Is the DO level acceptable? Is the DO level acceptable?(1.0 to 3.0 mg/l) Comment: Secondary Clarifier Yes No NA NE Is the clarifier free of black and odorous wastewater? Is the site free of excessive buildup of solids in center well of circular clarifier? Are weirs level? Is the site free of weir blockage? Is the site free of evidence of short-circuiting?

Is the site free of excessive floating sludge? Is the drive unit operational? Is the return rate acceptable (low turbulence)? Is the overflow clear of excessive solids/pin floc? Is the sludge blanket level acceptable? (Approximately ¼ of the sidewall depth) Clarifier skimmer had been repaired.Comment: Disinfection-Liquid Yes No NA NE Is there adequate reserve supply of disinfectant? (Sodium Hypochlorite) Is pump feed system operational? Is bulk storage tank containment area adequate? (free of leaks/open drains) Is the level of chlorine residual acceptable? Is the contact chamber free of growth, or sludge buildup? Is there chlorine residual prior to de-chlorination? Chlorine contact chambers still have deteriorating concrete and appear to be a safety risk. This was also noted in the August 2018 inspection. The cable fences are only appropriate as a temporary measure. Comment: Page#4 DocuSign Envelope ID: 3BAE30C0-86A2-4A5B-B11E-EB6D4F265E09
