This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0067342. JoeDavid Hall (ORC, Environmental Inc.) was present and assisted in the inspection. The following items were noted during the inspection: Permit: The Permittee has not submitted a permit renewal application that was due in September 2022. Because this renewal application has not been submitted, the facility is illegally discharging with an expired permit. There was an additional rectangular secondary clarifier installed at the facility, but it is not in use and never has been. This clarifier is not listed in the permit components. Equalization Basins: At the time of the inspection, the control panel that operates the floats and alarm was not working. The equalization basin is currently being used as a digester and should be converted back to an EQ basin in June 2023. Digester: At the time of the inspection, there were multiple hoses laying on the ground. Mr. Hall indicated that these hoses are used to decant the digesters. It is recommeded to install hard piping for decanting the digesters. Flow Measurement - Effluent: At the time of the inspection, the flow meter was greatly fluctuating, reading between 6 GPM and 130 GPM. Mr Hall indicated that Mr. Jim Queen with Engineered Systems Inc. had recently been out to calibrate the meter. It is recommended to have a different company come out to recalibrate the flow meter to determine if something needs to be fixed or replaced. Additionally, a staff gauge was not in place to verify flow, as previously recommended in the 2018 EPA Report. Effluent Sampling: It was unable to be determined whether or not the effluent composite sampler was set to flow-proportional. An aliquot was pulled during the inspection, and the volume was insufficient at 75 mL. Each aliquot should be at least 100 mL. There was no thermometer in the composite sampler fridge. The effluent sample is not being collected after all treatment components. The sample tubing should be moved to after dechlorination. According to NPDES Permit No. NC0067342, Section A. (1), Footnote #5, one of the weekly composite sampling events must be initiated on Mondays and collected on Tuesdays, and it was verified that this sampling regimen is occurring. The following violations were noted during the inspection: 1. Permit: The Permittee has not submitted a permit renewal application and the facility is illegally discharging with an expired permit. 2. Equalization Basins: The control panel for the equalization basin is broken, and therefore the floats and alarm are not functioning as intended. 3. Flow Measurement - Effluent: The flow meter was fluctuating during the inspection and did not appear to be properly working. 4. Effluent Sampling: The aliquot amount was insufficient and the sampling location was not after all treatment components. It could not be determined whether or not composite sampling was NC0067342 17 (Cont.)

There was no thermometer in the composite sampling fridge. The following compliance issues were noted during the inspection: 1. Digester: Decant lines for the digesters are currently hoses laying on the ground and hard lines should be installed. 2. Flow Measurement - Effluent: A permanent staff gauge was not installed in order to verify flow.

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? The permit expired on March 31, 2023 and a permit renewal application has not been submitted. Mr. Hall indicated that he would contact the Owner about submitting one. The facility has two digesters (three because the EQ basin is currently being used as a digester), and the permit lists one sludge holding tank under the components. See summary for details. Comment: Operations & Maintenance Yes No NA NE Is the plant generally clean with acceptable housekeeping? Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable Solids, pH, DO, Sludge Judge, and other that are applicable? Process controls analyzed include settleable solids, pH, DO, and a sludge judge for the clarifiers and chlorine contact basin. Per Section A. (3) of NPDES Permit No. NC0067342, Process Control Reports must be submitted monthly, and all reports have been submitted through April 2023. Comment: Record Keeping Yes No NA NE Are records kept and maintained as required by the permit? Is all required information readily available, complete and current? Are all records maintained for 3 years (lab. reg. required 5 years)? Are analytical results consistent with data reported on DMRs? Is the chain-of-custody complete? Dates, times and location of sampling Name of individual performing the sampling Results of analysis and calibration Dates of analysis Name of person performing analyses Transported COCs Are DMRs complete: do they include all permit parameters? Has the facility submitted its annual compliance report to users and DWQ? (If the facility is = or > 5 MGD permitted flow) Do they operate 24/7 with a certified operator on each shift?

Is the ORC certified at grade equal to or higher than the facility classification? Is the backup operator certified at one grade less or greater than the facility classification? Is a copy of the current NPDES permit available on site? Facility has copy of previous year's Annual Report on file for review? 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 is raked daily. Debris from the bar screen is dried and then disposed of in a trash can. Comment: Equalization Basins Yes No NA NE Is the basin aerated? Is the basin free of bypass lines or structures to the natural environment? Is the basin free of excessive grease? Are all pumps present? Are all pumps operable? Are float controls operable? Are audible and visual alarms operable? # Is basin size/volume adequate? The EQ basin is currently being used as an aerated digester. The panel that controls the floats and alarm does not work. The panel will be fixed or replaced. Mr. Hall said the EQ basin was temporarily converted to a digester in March 2023, but that it will be active as an EQ basin again around mid June. See summary for details Comment: Aeration Basins Yes No NA NE Mode of operation Ext. Air Page#5 DocuSign Envelope ID: 1E7992F6-BFC1-4315-B37A-43EF6A65A9FD Permit:NC0067342 Inspection Date:05/23/2023 Owner - Facility: Inspection Type: North View Mobile Home Park Compliance Evaluation Aeration Basins Yes No NA NE 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 blowers turn on every hour for fifteen minutes. Mr. Hall indicated that DO is usually between 1 to 2 mg/L. There are two aeration basins on-site, and they are distinguished by the old and new aeration basin. The new one is much larger than the old one. At the time of the inspection, settleability was 55% in the new aeration basin and 32% in the old aeration basin. 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 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) The facility consists of an older rectangular secondary clarifier and a newer circular secondary clarifier. At the time of the inspection, the sludge blanket was 1.5' in the 9' rectangular clarifier, and 5.5' in the 9' circular clarifier. Mr. Hall indicated that flow from both aeration basins first goes into the circular clarifier and then into the rectangular clarifier, which could be why the sludge blanket is higher in the circular one. Sludge is wasted from the clarifiers approximately three days a week. Comment: Aerobic Digester Yes No NA NE Is the capacity adequate? Is the mixing adequate? Page#6 DocuSign Envelope ID: 1E7992F6-BFC1-4315-B37A-43EF6A65A9FD Permit:NC0067342 Inspection Date:05/23/2023 Owner - Facility: Inspection Type: North View Mobile Home Park Compliance Evaluation Aerobic Digester Yes No NA NE Is the site free of excessive foaming in the tank? # Is the odor acceptable? # Is tankage available for properly waste sludge? There are three digesters used at the facility - the old digester, new digester, and the EQ basin that was converted into a digester (will soon be used as an EQ basin again). Mr. Hall indicated that sludge from the digesters is wasted in rotation, and decant from the digesters goes back to the splitter box. See summary for details. Comment: Disinfection-Tablet Yes No NA NE Are tablet chlorinators operational? Are the tablets the proper size and type? Number of tubes in use?1 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? The 2018 EPA Report indicated that the chlorine contact chamber had noticeable amounts of floating solids and debris. At the time of the inspection, there were no floating solids and debris, but there was duck weed, and the sludge blanket level was 1.25' out of an 8' contact chamber. The old chlorine contact chamber is used as needed. Sludge from the contact chamber returns to the aeration basins. Comment: De-chlorination Yes No NA NE Type of system ?Tablet 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? Number of tubes in use?1 Comment: Flow Measurement - Effluent Yes No NA NE # Is flow meter used for reporting? Is flow meter calibrated annually? Is the flow meter operational? Page#7 DocuSign Envelope ID: 1E7992F6-BFC1-4315-B37A-43EF6A65A9FD Permit:NC0067342 Inspection Date:05/23/2023 Owner - Facility: Inspection Type: North View Mobile Home Park Compliance Evaluation Flow Measurement - Effluent Yes No NA NE (If units are separated) Does the chart recorder match the flow meter? The effluent flow meter was last calibrated on May 11, 2023 by Engineered Systems Inc. Mr. Hall indicated that they had previously purchased a staff gauge, but he could not find it during the inspection. The flow meter is operational; however, at the time of the inspection, the flow measurement significantly fluctuated and was reading 6 GPM to 130 GPM. See summary for details. Comment: Effluent Pipe Yes No NA NE Is right of way to the outfall properly maintained? Are the receiving water free of foam other than trace amounts and other debris? If effluent (diffuser pipes are required) are they operating properly? Comment: Effluent Sampling Yes No NA NE Is composite sampling flow proportional? Is sample collected below all treatment units? Is proper volume collected? Is the tubing clean? # Is proper temperature set for sample storage (kept at less than or equal to 6.0 degrees Celsius)? Is the facility sampling performed as required by the permit (frequency, sampling type representative)? At the time of the inspection, there was no thermometer inside the fridge of the composite sampler. It could not be verified whether or not flow-proportional composite sampling was being conducted. The sampler was pulling 75 mL per pulse and it should be pulling at least 100 mL. See summary for details. Comment: Standby Power Yes No NA NE Is automatically activated standby power available? Is the generator tested by interrupting primary power source? Is the generator tested under load? Was generator tested & operational during the inspection? Do the generator(s) have adequate capacity to operate the entire wastewater site? Is there an emergency agreement with a fuel vendor for extended run on back-up power? Is the generator fuel level monitored?
