Your assistance during the inspection was greatly appreciated. Our records indicate the treatment system consists of a septic tank, pump tank, sub -surface sand filter, tablet chlorinator with chlorine contact chamber, and the associated appurtenances with the discharge of treated wastewater. General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550978 authorize the discharge of domestic wastewater from your treatment system to receiving waters designated as an unnamed tributary to Cabin Branch 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: I. 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. Within 30-days of receiving this letter, please send a copy of the most recent receipilinvoice to this office showing the date the septic tank was last checked and/or pumped our. _ENorth Carolina Depamnent of Envtroomental Qualiry I Division of Water Resources Q 5 Raleigh Regional Office 1 3800 Barrett Drive I Raleigh, North Carohna 27609 919.791.4200 DocuSign Envelope ID: A60802BC-AAA4-4FA4-9150-8BC25A5912D4 The General NPDES Permit requires the permittee to retain records associated with sewage disposal activities for a period of at least 5 years. 3.

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. Part II Section B.14 of General Permit NCG550000 requires the permittee to "pay the annual administering and compliance monitoring fee within thirty days after being billed by the Division."
