Mr. Lance Ingram was present and assisted with the inspection. The following issues were noted during the inspection: Flow meter calibration is not documented. The calibration should show a maximum deviation of less than 10% from the true discharge rates. A more reliable measuring (ruler/yard stick) device is recommended to ensure accuracy of the calibration. The composite sampler was not working at the time of inspection. As a result, all samples collected on March 19th were grab; BOD, TSS and Ammonia are required to be composite. Flow proportional sampling is not being conducted. Constant time/constant volume is being used: Use of this method requires prior approval. All maintenance and process control checks should be documented in the log book. Solids pumping should be documented. The audible/visual alarms were not working on the influent pump station/EQ basin. Safety: The following are potential safety issues for the operator: 1. The ORC uses extension ladders to access the reactor for sludge judge measurement. 2. The ORC uses a hose to remove foam from the reactor. The hose extends across the walkway between the SBR and the digester. Recommendations: 1. Plywood extensions have been added to the chlorine contact basin baffles to prevent short circuiting. The ORC reports that this was done due to elevated fecal coliform levels in the past. The system should be evaluated to determine if there is short-circuiting and if so, why. Also, possibly evaluate whether a liquid chlorine feed would be more appropriate for this system or add additional chlorine tablets. The system currently uses chlorine tablets. 2. Assess solids management in the facility. Settleable solids test showed approximately 850ml-900ml (settling was uneven) of solids. More frequent pumping of solids may be required. Perform a MLSS test to determine the amount of solids in the reactor. There was an excessive amount of foam in reactor #1. The ORC reports that Nocardia is the cause. Nocardia can be associated with longer Solids Residence Time (SRT). Verify filamentous growths by conducting a microscopic examination of the foam and the mixed liquor. Filamentous growth can cause Nocardia. Excessive grease is also a known cause of Nocardia. Restaurant grease traps may need to be pumped more frequently. Wasting may need to be increased. Foam may need to be physically removed with a vacuum truck. 3. Evaluate the capacity of the digester. The ORC reports hauling 2000-4000 gallons approximately every two weeks. NC0057193 17 (Cont.)

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 cover letter shows this as a Class I facility. The database and previous permit letter indicate a Class 2 facility; this is a Class 2 facility. The permit description does not show a standby generator. The facility uses a Kohler generator. 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? Sludge judge - for reactor Settleable solids 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? There were a lot of solids on the bar screen.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? Page#3 DocuSign Envelope ID: AC813FED-F50F-4044-A210-6C9FB1E8DFAF Permit:NC0057193 Inspection Date:03/20/2019 Owner - Facility: Inspection Type: Nantahala Outdoor Center Compliance Evaluation Pump Station - Influent Yes No NA NE Is audible and visual alarm available and operational? Audible & visual alarms were not working. 2 spare pumps were on-site. The ORC reports that grease does not seem to be an issue in the influent pump station and grease traps for restaurants at the facility are pumped approximately once per month during the season. Grease traps are pumped approximately every six weeks during the off-season. Comment: Sequencing Batch Reactors Yes No NA NE Type of operation:Duplex Is the reactor effluent free of solids? Does minimum fill time correspond to the peak hour flow rate of the facility? Is aeration and mixing cycled on and off during fill? The operator understands and can explain the process? The reactors are always mixing but air valves are set on timers. There was an excessive amount of foam in reactor #1. The ORC reports that Nocardia is a problem and it is removed via a hose that stays connected to the reactor. The ORC checks solids levels in the reactor to determine when to waste to the digester. If supernate is less than 4 ft from the sludge blanket, solids are wasted to the digester. 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 ORC reports that 2000-4000 gallons of sludge is pumped approximately every 2 weeks and that pumping is more frequent than expected. 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?

Post EQ Basin - New pump was on-site and ready to be placed in the EQ Basin. Any solids that accumulate are pumped back to the digester. Chlorine tabs are used to control algae. The basin contains diffusers but they are not used. 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? Plywood extensions had been added to the concrete baffles to prevent short circuiting according to the ORC. This was done due to elevated fecal coliform results in the past. Comment: De-chlorination Yes No NA NE Type of system ?Liquid 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? Are the tablets the proper size and type? Chlorination is accomplished using tablets.Comment: Are tablet de-chlorinators operational? Number of tubes in use? 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)?

The composite sampler was not working at the time of inspection. The motor and controls had stopped working. The sample collected on March 19th was a grab sample because the sampler was down. 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? Calibration is done by the ORC but is not being documented. The meter has a strip chart but it is not connected. 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: 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? The permittee maintains a service contract and fuel levels are checked by the ORC. The generator was turned on and was operational but was no tested under load during the inspection. Fuel level indicated 3/4 full.
