NORTH CAROLINA Director Environmental Quality May 5, 2022 Rebecca Whittlesey 3421 Coley Road Durham,NC 27703 Subject: Compliance Evaluation Inspection Single Family Wastewater Treatment System General NPDES Permit NCG550000 Certificate of Coverage NCG551414 Facility: 3421 Coley Road Durham County Dear Ms. Whittlesey: On April 28, 2022, Alys Hannum from the Raleigh Regional Office visited your single-family residence wastewater treatment system to evaluate compliance with the subject General National Pollution Discharge Elimination System(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 with chlorine contact chamber, tablet dechlorinator, discharge pipe and a rip-rap apron for post aeration. General NPDES Permit NCG550000 and Certificate of Coverage (COC)NCG551414 authorize the discharge of domestic wastewater from your treatment system to receiving waters designated as Laurel Creek(classified WS-IV NSW) in the Neuse River Basin, in accordance with the effluent limits and monitoring requirements established within the General Permit. The following conditions were noted at your facility: • 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. After the inspection, both you and Scotty's Septic Services confirmed that the previous homeowner had pumped out the septic tank in March of 2021 but were unable to provide records. For future records,please note that the General NPDES Permit requires the permittee to retain records associated with sewage disposal activities for a period of at least 5 years.

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. The inspector observed chlorine tablets in the chlorinator.Please continue to ensure the correct type of tablets are used and maintained in the chlorinator as required by the General NPDES Permit. • Dechlorination tablets: You are responsible for always having dechlorination tablets (if a required part of your system) in place. They must be the kind for wastewater treatment and not for swimming pools. The inspector observed dechlorination tablets in the treatment unit.Please continue to ensure the correct type of tablets are used and maintained in the dechlorinator as required by the General NPDES Permit. • 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 and Total Residual Chlorine. Within 30 days of receiving this letter, please inform this office if you have monitored your effluent discharge within the last 12 months and provide 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 within 90 days. 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. • 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 the outlet is always visible/maintained and cleared of vegetation, soil and leaves.
