This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0068918. Mr. Kenneth Rummel (ORC, RPB Systems) and Mr. Bob Barr (Owner, RPB Systems), and Mr. Jeffrey Moore (collection system operator) were present and assisted with the inspection. There are currently 20-30 homes connected to the collection system for the facility. Due to the seasonality of residents at this development, at the time of the inspection there was very low flow to the plant. This has caused there to be very low solids throughout the facility. The following items were noted during the inspection: Equalization Basins: It is recommended that an audible alarm be added to the equalization basin or that the EQ basin be connected to telemetry. Aeration Basins: The dissolved oxygen measurement at the time of the inspection was undesirably high with a measure of 12.73 mg/L. Pump Station-Effluent: An auto-dialer is installed on the effluent pump station, however it is recommended to check to ensure the telemetry service is still active. The following violation was found during the inspection: Effluent Sampling: Effluent composite sampling is required to be flow-proportional. At the time of the inspection, it was being performed as time-based due to the older model flow meter that does not accommodate flow proportional. It is recommended to replace the flow meter to a model that is able to accomodate flow proportional sampling. Additionally, it is recommended that a thermometer be placed in the sample storage refrigerator. NC0068918 17 (Cont.)

Are audible and visual alarms operable? # Is basin size/volume adequate? At the time of the inspection, the visual alarm was working, however an audible alarm was not present. It is recommended that an audible alarm be added to the EQ basin. See summary for details. 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? Page#4 DocuSign Envelope ID: FDBA9305-CDB3-4E80-9660-CF1AA66CF9E4 Permit:NC0068918 Inspection Date:02/29/2024 Owner - Facility: Inspection Type: Cedar Hill WWTP Compliance Evaluation Aeration Basins Yes No NA NE 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) Due to the low flow entering the facility at the time of the inspection, there were very low solids in the plant. A settleability test was performed, but the low solids present may not have given an accurate representation of settleability. After thirty minutes, there were 4 mL of solids out of 1000 mL of water. The DO was undesirably high at the time of the inspection, it measured to be 12.73 mg/L. See summary for details. 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) Due to the low flow and solids in the plant, the sludge blanket level was very low. A sludge judge showed about three inches of solids out of ten feet of water in the clarifier at the time of the inspection. There was a layer of algae on top of the clarifier at the time of the inspection that the ORC states is very difficult to remove entirely. 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 digester decants to aeration basins #1 and #2.
