Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG550846
Facility: 169 Williford Point Road
Person County

Dear Mr. and Mrs. Burton:

On March 3, 2021, Stephanie Goss from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment system to evaluate compliance with the subject General
NPDES Permit. The assistance you provided over the telephone was greatly appreciated.

Our records indicate the treatment system consists of a septic tank, pump tank, sub-surface sand
filter, secondary 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) NCG550846 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
as Hyco River classified as WS-V, Class B waters in the Roanoke River Basin. The authorized
discharge is in accordance with the effluent limits and monitoring requirements established
within the General Permit. The following shows what conditions were noted at your facility:

NCG550000 Ownership Change Form: According to Person County deed of records, Miriam
and Charles Burton owns the residence and property located at 169 Williford Point
Road in Roxboro, North Carolina. As the property owner, you are also the owner of the existing
single-family wastewater treatment system, which treats the domestic wastewater from the
residence and releases the effluent to the receiving waters indicated above. Because the
treatment system makes an outlet to waters of the state, it is an activity for which the subject
permit is required. To comply with North Carolina General Statute § 143-215.1(a), which
requires a person to obtain a permit to make an outlet into the waters of the state, you will need
to complete and submit the attached NCG550000 Ownership Change Form to the Division. If
you have any questions regarding change in permit ownership or completing the form, then
please contact Stephanie Goss at 919-791-4256.

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 receipt/invoice to this office showing the date the
septic tank was last checked and/or pumped out. 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 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 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.

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. During the inspection, you informed the inspector that the effluent
has not been monitored within the last 12 months. 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 June 1, 2021. 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. 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.

The wastewater treatment system should be periodically inspected to ensure the treatment
components are always maintained and in good operating order. You are also reminded to
maintain all monitoring data and associated maintenance records onsite for a minimum of three
years and available for inspection.

Within 30-days receipt of this letter, please submit a written response to this office indicating the
actions you will take or have taken to comply with or resolve the issues noted above.

If you have questions or comments about this inspection or the requirements to take corrective
action (if applicable), then please contact Stephanie Goss at [e-mail] or 919-
791-4256.
