This is a class II activated sludge wastewater facility. The facility has a history of noncompliance with permit limits and $12,000 in enforcements in the past 10 years. Mark Jones has very recently taken responsibility for operation of the facility (May 1, 2018). Here are the conditions of the facility according to Mark on his first visit of the facility: 1. One of the two aeration basin diffusers was not in operation. 2. The D.O. in the aeration basin was <1 mg/L. 3. One of the two blowers did not have any pulleys or belts on it. 4. The pretreatment septic tank contained 70% solids. Mark said it had never been pumped. Mr. Benson said the previous ORC was not aware that the septic tank existed. 5. The aeration basin contained 90% settleable solids. 6. Rusted gratings and structure. One pipe was leaking between the clarifier trough and the chlorinator. 7. Broken timer on the one operating blower. Already Mark has taken the following actions: 1. Pumped solids out of the aeration basin. It is now at 35% settleable solids in one hour. 2. Pumped out the septic tank. 3. Repaired the timer on the blower. 4. Repaired the diffuser that was not operating. Measured D.O. is now 2.4 mg/L. 5. Added pulleys to the blower not in operation in case of need for immediate use. I took effluent samples for TSS, BOD, and fecal coliform. Results are as follows: Fecal- 30 col/100ml, BOD- 12mg/L, TSS- 150 mg/L. TSS was the only parameter that exceeded permit limits. Please continue making improvements to the facility and operations to get this parameter into compliance. NC0066362 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? We could not find the outfall.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? Comment: Septic Tank Yes No NA NE (If pumps are used) Is an audible and visual alarm operational? Is septic tank pumped on a schedule? Are pumps or syphons operating properly? Are high and low water alarms operating properly? 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) Foam covered probably 40% of the surface. I expect this to reduce from the improved plant operation.
