NCO068152 111 121 18/06/20 117 18 S Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The inspectors, Linda Wiggs and Tim Heim met with Joe David Hall (ORC). The plant was observed to be producing good quality effluent at the onset of the inspection and during the split sampling. However, further into the inspection there appeared to be a hydraulic "surge" from the aeration basin through the clarifier that move a significant amount of solids into the chlorine contact chamber and subsequently the receiving stream. Split samples, DWR results were: Fecal Coliform — 96 CFU/100ml BOD — 6.8 mg/I TSS — 8.3 mg/I NH3 — 0.04 mg/I Solids were high in the plant and did not settle. The ORC stated the digester had been pumped May 11, 2018 by Carter Septic. Considerable structural decay was observed throughout the WWTP. Refer to TA report for additional comments.

Comment: Observations and process controls conducted during inspection indicate solids issues. Considerable structural decay was noted. Solids were observed in effluent after blower shut-off. See summary and TA report. Permit (If the present permit expires in 6 months or less). Has the permittee submitted a new application? Is the facility as described in the permit? # Are there any special conditions for the permit? Is access to the plant site restricted to the general public? Is the inspector granted access to all areas for inspection? Comment: Aeration Basins Mode of operation Type of aeration system 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/1) Yes No NA NE ❑ ❑ ■ ❑ ■ ❑ ❑ ❑ ❑ ❑ ■ ❑ • ❑ ❑ ❑ • ❑ ❑ ❑ Yes No NA NE ■ ❑ ❑ ❑ ❑ ❑ ■ ❑ • ❑ ❑ ❑ • ❑ ❑ ❑ ❑ ■ ❑ ❑ ❑ ❑ ❑ ■ ❑ ❑ ❑ Comment: D.O. readings were between 2.87-3.47 mg/I. Air was set for 30 min.ON/45 min. OFF. Settleability was unacceptable at 95%. Foam approaching 50%. Considerable structural decay was noted at aeration basin and clarifier function/wall. See summary and TA report.

Is the site free of weir blockage? Is the site free of evidence of short-circuiting? Is scum removal adequate? 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?

Excessive solids left the clarifier; a surge occurred when the blower shut-off. This hydraulic surge also allowed wastewater to bypass the chlorine tablets tube, predominantly where structural decay was present. See summary and TA report. Disinfection -Tablet Are tablet chlorinators operational? Are the tablets the proper size and type? Number of tubes in use? 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? Comment: Chlorine contact blanket was 1.576'. Structural issues were noted at the tablet chlorinator and the clarifier iunction. De -chlorination Type of system ? Is the feed ratio proportional to chlorine amount (1 to 1)? Is storage appropriate for cylinders? # Is de -chlorination substance stored away from chlorine containers? Comment: Are the tablets the proper size and type? Are tablet de -chlorinators operational?
