REGAN Secretary LINDA CULPEPPER Director James Baxter 22 South Circle Drive Chapel Hill, NC 27516 dTpc Sw tJq, oa - �girNirA� NORTH CAROLINA Environmental Quality March 22, 2019 Subject: Compliance Evaluation Inspection Single Family Wastewater Treatment System NPDES General Permit NCG550000 Certificate of Coverage NCG551662 Orange County Dear Mr. Baxter: On March 2I, 2019, Vanessa Manuel from the Raleigh Regional Office visited your single-family residence (SFR) wastewater treatment system to evaluate compliance with the subject NPDES General Permit. Your assistance during the inspection was greatly appreciated. Our records indicate the treatment system consists of a septic tank with effluent filter, an AdvanTex Pod treatment system, a re -circulation pump chamber (integrated into the AdvanTex Pod system), an Ultra - Violet disinfection system, a control panel, and an effluent discharge pipe with aeration/erosion-controlled rip -rap. General Permit NCG550000 and Certificate of Coverage (COC) NCG551662 authorize the discharge of domestic wastewater from your treatment system to receiving waters designated as an unnamed tributary to Fan Branch (classified WS-IV; NSW) in the Cape Fear River Basin. The authorized discharge is in accordance with the effluent limits and monitoring requirements established within the General Permit. The checked boxes below show what conditions were noted at your facility: ® Treatment system operation: The wastewater treatment system shall be maintained at all times to prevent seepage of sewage to the surface of the ground. ® 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 Ili of the Iiquid depth in the septic tank compartment, whichever is greater. A pumping company or your contract operator can check the status periodically and determine when pumping is required. During the inspection, you informed the inspector that the treatment system was installed 3 years ago. As required by the NPDES General Permit, please check the septic tank periodically and determine when pumping is needed. North Carolina Department of Environmental QuatityDivision of Water Resources Raleigh Regional Office 1 3800 Barrett Drive ' Raleigh. North Carolina 27609 9197914200 .�- D Q��/�j James Baxter (22 South Circle Dr., Cie Hill), NCG551662 March 22, 2019 Page 2 of 2 ® UV Disinfection: Your system uses an ultra -violet (UV) light system for disinfection of the discharged wastewater. New rules put into place on August 1, 2007 require all SFR systems to have a means of disinfection (and dechlorination when chlorine tablets are used to disinfect, if the system was installed since that date). A UV disinfection system provides effective disinfection and prevents/limits harmful bacteria from discharging to the environment. Unless the UV disinfection unit is monitored by telemetry, the unit shall be checked weekly. The lamp(s) and quartz sleeve(s) shall be cleaned or replaced as needed to ensure proper disinfection of the discharged wastewater. Please continue to ensure the UV disinfectio►n unit is properly operated and maintained to ensure opthnal perfornna►►ce. ® Analyzing the effluent: Part 1. A., Effluent Limitations and 11llonitoring 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 and Total Residual Chlorine (if Chlorine is used for disinfection). Documentation from McFarland Septic shows the effluent discharge was monitored on January 25, 2019, and the analytical results from ENCO Laboratories show the effluent parameters were below permit limits. Please continue to monitor your effluent discharge and collect a representative sample for analysis at least annually. ® 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 discharge pipe was visible and accessible the day of the inspection. Please continue to ensure life outlet is always maintained and cleared of vegetation, soil and leaves. Please continue to periodically inspect the wastewater treatment system to ensure the treatment components are always maintained and in good operating order. You are also reminded to maintain all monitoring data onsite for a minimum of three years from date of sampling and available for inspection. If you have questions or comments about this inspection or the requirements to take corrective action (if applicable), then please contact Vanessa Manuel at 919-791-4255. Licensed plumbers should be used to make plumbing changes within your home. Contractors for installing disinfection or other equipment may be found in the Yellow Pages under Environmental Consultants.
