Your assistance during the inspection was greatly appreciated. Our records indicate the treatment system consists of a septic tank, sub -surface sand filter, tablet chlorinator with chlorine contact chamber, de -chlorinator, and discharge pipe. General NPDES Pen -nit NCG550000 and Certificate of Coverage (COC) NCG551613 authorize the discharge of domestic wastewater from your treatment system to receiving waters designated as an unnamed tributary to Rocky Branch (classified Water Source (WS-IV); Nutrient Sensitive Waters (NSW) in the Neuse River Basin. The authorized discharge is in accordance with the effluent limits and monitoring requirements established within the General Permit. The items below show what conditions were noted at your facility: Findings during the inspection were as follows: 1. Treatment system operation: The wastewater treatment system shall be maintained at all times to prevent seepage of sewage to the surface of the ground. 2. Pumping the septic tank: You are required to inspect the septic tank at least yearly to determine if solids must be removed or if other maintenance is necessary. Septic tanks should be pumped out every five years or when the solids level is found to be more than 1/3 of the liquid depth in the septic tank compartment, whichever is greater. A pumping company can check the status North Carolina Department of Environmental Quality i Division of Water Resources Raleigh Regional Office 13800 Barrett Drive I Raleigh, North Carolina 27609 rr erora 919.791,4200 Docusign Envelope ID: D3363975-AFAR-4131-963A-CBA073C8DC56 ivir. maLrnew rang, IVLLr��lUl3 September 20, 2024 Page 2 of 3 periodically and determine when pumping is required. No septic tank cleaning records were available at the time of the inspection. Please schedule to have your septic tank cleaned by November 15, 2024.

C., Effluent Limitations and Monitoring Requirements, within General Permit NCG550000 requires a permittee to sample and analyze the effluent leaving his/her treatment system prior to discharge annually. Parameters to be sampled and analyzed include Flow, BOD (Biochemical Oxygen Demand), Total Suspended Solids, Fecal Coliform, Total Residual Chlorine, Total Nitrogen, Ammonia Nitrogen and Total Phosphorous During the inspection, you informed the inspector that the effluent has not been monitored within the last 12 months due to no discharge flow being observed. Within 30-days of receiving this letter, please collect a representative sample of the effluent, have it analyzed by a certified commercial laboratory and submit the results to this office no later than November 30, 2024 If, during this time, you are unable to collect a representative sample of the effluent discharge due to insufficient flow from the discharge pipe, then update this office with that information and continue to monitor the discharge and if conditions for sampling become favorable, then arrange to collect a sample. Failure to monitor the effluent discharge as required is a violation of NPDES General Permit NCG550000. 4.
