REGAN Seci etary LINDA CULPEPPER lnterun Du ectot RECE ED/DE 9ROW FEB 0 5 2018 Neter Resources Permitting Section On January 25, 2018, Vanessa Manuel from the Raleigh Regional Office visited your single-family residence (SFR) wastewater treatment system to evaluate compliance with the above NPDES permit to discharge wastewater. Your assistance during a telephone conversation on January 29, 2018, was greatly appreciated. Our records indicate the treatment system consists of a septic tank, sub -surface sand filter, tablet chlorinator and chlorine contact chamber. The subject Certificate of Coverage authorizes the discharge of domestic wastewater from your treatment system to receiving waters designated as New Hope Creek (classified WS -V; NSW) in the Cape Fear River Basin in accordance with the effluent limits and monitoring requirements established within General Permit NCG550000. The checked boxes below show what conditions were noted at your facility: ® 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. Please continue to ensure the correct type of tablets are used and maintained in the chlorinator. ® 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. As you stated during the telephone conversation with the inspector, the septic tank was cleaned out during June 2015. The next scheduled cleaning will be in 2020. Please continue to monitor the septic tank as required. ® Analyzing the effluent: Part 1.
