This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0022756. Mr. C.L. Lewis (ORC) was present and assisted with the inspection. The facility appears to be well maintained and operated. There were no compliance issues found. The following items were noted during the inspection: 1) Operations & Maintenance- Mr. Lewis noted that there is one restauraunt on site that has a grease trap and at present it does not cause grease problems for the facility. He also noted that they do receive some grease from the houses within the development, but it has not caused major issues up to this point. 2) Equalization Basins- Mr. Lewis indicated that the collection system has issues with I&I and the EQ basin helps stabilize the plant during times of heavy flow. 3) Effluent sampling- The thermometer was not in the unit at the time of the inspection, but in the facility office. The thermometer should be replaced to the sampler when sampling events occur. NC0022756 17 (Cont.)
