This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0033553. Deborah Bradley, ORC, was present and assisted in the inspection. Overall, the facility appeared to be in compliance. The operator logbook was reviewed, and the ORC was taking pH, temp and chlorine readings at the time of the inspection and estimating flow. The school contracts Triple A Septic to pump the tanks onsite. Sand filter beds appeared to be raked and free of vegetation and ponding. Drain valves were closed at the end of the perforated drain lines and there was no indication of overloading occurring across the beds. ORC indicated School staff usually remove any weeds/vegetation from the sand filter beds. No issues reported with effluent numbers due to increased cleaning protocols since Covid. Ms. Bradley stated the School was obtaining quotes to replace the media of the sand filter beds. The School may also pursue upgrading the wastewater treatment facility if budget allows. The sample location is downstream of all treatment components; however, the sample port size makes sampling and flow estimation more difficult. Recommend increasing the size of the sampling port if/when the facility is next upgraded, since the effluent pipe is across the highway and a field. Currently there is not a spigot near the wastewater system. It is recommended the school provide a means to rinse down any treatment components for routine cleaning for operations and maintenance staff. NC0033553 17 (Cont.)
