NORTH CAROLINA Director Environmental Quality May 28, 2024 Douglas Satterfield 108 Debra Drive Durham,NC 27704 Subject: Compliance Evaluation Inspection Single Family Wastewater Treatment System General NPDES Permit NCG550000 Certificate of Coverage NCG550839 Facility: 108 Debra Drive Durham County Dear Ms. Satterfield: On May 21, 2024, Donald Smith from the Raleigh Regional Office visited your single-family residence (SFR) wastewater treatment system to evaluate compliance with the subject General NPDES Permit. 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, and discharge pipe. General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550839 authorize the discharge of domestic wastewater from your treatment system to receiving waters designated as Panther Creek (classified WS-IV; 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 periodically and determine when pumping is required. During the inspection,you provided documentation showing Scotty's Septic Service pumped out the D North Carolina Department of Environmental Quality I Division of Water Resources Raleigh Regional Office 13800 Barren Drive I Raleigh,North Carolina 27609 919.791.4200 DocuSign Envelope ID:5B42A50E-1A22-4174-A220-DCOFD9OF9E97 Mr. Douglas Satterfield,NCG550839 May 28,2024 Page 2 of 3 septic tank in April 2024. The General NPDES Permit requires the permittee to retain records associated with sewage disposal activities for a period of at least 5 years. 3. Chlorine tablets in the chlorinator:You are reminded that it is required that chlorine tablets be maintained in the chlorinator to ensure proper disinfection of the discharged wastewater. Chlorine tablets provide effective disinfection and prevent/limit harmful bacteria from discharging to the environment. The Product label for these tablets must indicate the tablets are approved for wastewater use and not for swimming Pools. Part 1, Section D (1) of General NPDES Permit NCG550000 requires the permittee to inspect the tablet chlorinator weekly to ensure there is an adequate supply of tablets for continuous and proper operation. Section D (4) requires the permittee to maintain all system components, including disinfection units, at all times and in good operating order. The inspector did not observe any chlorine tablets in the chlorinator. Please obtain and ensure the correct type of tablets are used and maintained in the chlorinator as required by the General NPDES Permit 4. Discharge outlet location. The permittee is required to conduct a visual review of the outfall location at least twice each year(one at the time of sampling)to ensure that no visible solids or other obvious evidence of system malfunctioning is observed. Any visible signs of a malfunctioning system shall be documented,and steps taken to correct the problem. The end of discharge pipe was not visible nor accessible the day of the inspection. To comply with the general permit monitoring requirements, you need to be able to sample and analyze the effluent from your SFR system through the discharge pipe. You need to keep the area around the discharge pipe cleared of vegetation, soil, and leaves. Please take the necessary steps to ensure the discharge outlet is visible and accessible. Maintaining the area will allow you to monitor the discharge and to collect effluent samples as required by the subject permit. 5. Analyzing the effluent: Part 1. 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. Within 30-days of receiving this letter,please let this office know if you have monitored your effluent discharge within the last 12 months and provide this office with a copy of the lab results if you have. If you have not monitored your effluent, then 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 August 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.
