Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
NPDES General Permit NCG550000
Certificate of Coverage NCG551317
Facility Name: 1312 Mockingbird Lane, Durham
Durham County
Dear Ms. Lopez:
On January 18, 2023, Mitch Hayes from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment system to evaluate compliance with the subject General
NPDES Permit. No one was home during the inspection.
Our records indicate the treatment system consists of a septic tank, dosing tank, sub -surface sand
filter, tablet chlorinator with chlorine contact chamber, discharge pipe and a rip -rap apron for
post aeration.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551317 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
as an unnamed tributary to Little Lick Creek classified WS-IV; NSW 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:
1. 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
receiptlinvoice to this office showing the date the septic tank was last checked andlor

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.
3. 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 let this office know if you have monitored your effluent
discharge within the last 12 months and provide this office with 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 no later than April 3, 2023. 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 ofNPDES
General Permit NCG550000.
4. Locations of treatment units are unknown: Within 30-days of receiving this letter,
provide this office with a sketch or map of the location of the treatment units septic tank,
sandfllter, chlorinator, and end of discharge pipe in relation to the permitted residence.
5. 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 end of discharge pipe was not visible 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. 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 in items 2, 3,
and 4 above.
