Chris McHugh (EPA inspector), Mikal Willmer (DWR), Tim Heim (DWR), and Linda Wiggs (DWR) were also present for the inspection. Overall the plant seemed to be operating very well and samples indicate an effluent within permit limits. Vince Edwards and Chris McHugh set up separate composite samplers for flow proportional sampling. The EPA's sampler began sampling at approximately 11am on 2/11/2019 and ended at 10:30am on 2/12/2019 and Mr. Edwards had a similar time period for his composite sample. I took samples for analysis of BOD and TSS from both composite samples. Sample Analysis Results: EPA Sampler- 13 mg/L BOD, 14 mg/L TSS Facility Sampler- 13mg/L BOD, 15 mg/L TSS Mr. McHugh mentioned that the position of the transducer for the WWTP's flow meter should be closer to the water level and farther back from the weir plate. Mr. McHugh also mentioned that the facility's sampling jug should be elevated higher than the sampling point. The weir plate also seems to be to small since the plant flow sometimes rises above the top of the V-notch. The influent pump station control needs an audio alarm. The visual alarm and the autodialer were both working. The air flowing to the digester was restricted and not adequate to mix or aerate the sludge. NC0067288 17 (Cont.)

There were two typos on the DMRs that were reviewed, they did not make any difference in terms of compliance. Comment: Pump Station - Influent Yes No NA NE Is the pump wet well free of bypass lines or structures? Is the wet well free of excessive grease? Are all pumps present? Are all pumps operable? Are float controls operable? Is SCADA telemetry available and operational? Is audible and visual alarm available and operational? There is no audio alarm, but there is an auto-dialer.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) The basin DO measured 4.6 mg/L. The settleability of the sludge was 17% in 30 minutes. Basins are operated at a time sequence of 45 min on and 15 min off. Comment: Pumps-RAS-WAS Yes No NA NE Are pumps in place? Are pumps operational? Are there adequate spare parts and supplies on site? RAS/WAS pumps are air lift pumps.Comment: Secondary Clarifier Yes No NA NE Page#4 DocuSign Envelope ID: FC9523A4-7002-40C0-A3D7-D790300D6907 Permit:NC0067288 Inspection Date:02/11/2019 Owner - Facility: Inspection Type: Hunter's Glen WWTP Compliance Sampling 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 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? (Approximately ¼ of the sidewall depth) There are 2 clarifiers in series, the final clarifier had a blanket of 1' of 9'. The initial clarifier had a blanket of 3' of 8' depth. Comment: Aerobic Digester Yes No NA NE Is the capacity adequate? Is the mixing adequate? Is the site free of excessive foaming in the tank? # Is the odor acceptable? # Is tankage available for properly waste sludge? The air flowing to the digester was restricted and not adequate to mix or aerate the sludge. The digester is pumped out about 3 times per year according to Mr. Edwards.

Number of tubes in use?2 The Total Residual Chlorine measured less than 10 ug/L post dechlorination.Comment: Flow Measurement - Effluent Yes No NA NE # Is flow meter used for reporting? Is flow meter calibrated annually? Is the flow meter operational? (If units are separated) Does the chart recorder match the flow meter? The flow meter program setup was incorrect. The meter was programmed for a 45 degree v-notch weir, but the weir is actually a 30 degree v-notch. This was corrected in the programming during the inspection.

The ORC said he would fix/replace the thermometer. Mr. McHugh discovered that the flow meter was not programmed correctly and fixed the problem onsite. The meter was reading as if the facility used a 45 degree v-notch weir, when in fact the v-notch weir was 30 degrees. Mr. McHugh also recommended moving the sampler to a position at the plant where it would be elevated above the level of where the sample is being drawn from. Finally Mr. McHugh suggested a better position for transducer, farther back from the weir plate and at an elevation nearer to the wastewater. The weir plate appears to be to small for accurate flow measurement since the plant flow sometimes goes above the top of the V-notch.
