Subject:
Compliance Evaluation Inspection
Permit #: NCG551243
Facility: 4545 US Highway 15
Granville County
On September 6, 2023, Jim Westcott from the Raleigh Regional Office visited your wastewater
treatment system to evaluate compliance with the subject Permit. The telephone conversation
with Mr. Espita at the time of the inspection was appreciated.
Facility records indicate the treatment system is permitted for the operation of a 240 gpd
system consisting of a 900-gallon septic tank with an effluent filter, dual sub -surface sand
filters, a secondary sand filter, tablet chlorinator and discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage NCG551243 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated
as an unnamed tributary of Boulding creek classified as class C Nutrient Sensitive Waters
(NSW) in the Tar -Pamlico River Basin. The authorized discharge is in accordance with the
effluent limits and monitoring requirements established within the General Permit.
The permit, which was issued June 10, 2021, will expire October 31, 2025. Division records
indicate the required annual fee for the period ending January 31, 2024, due February 3,
2023, is overdue. As found in Part 1, D (7) of the permit, Certificate of Coverage with unpaid
annual fees will not be automatically renewed. To ensure your permit is renewed
automatically, please remit payment.

Findings during the inspection were as follows:
1. Treatment system Operation: The wastewater treatment system shall be effectively
maintained and always operated so there is no discharge to surface waters, nor any
contravention of groundwater or surface water standards. At the time of inspection, the
permittee was not on site. The facility grounds and all components of the system appeared
to be well maintained.
2. Pumping the septic tank: You are required to inspect the septic tank annually 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. The non -discharge
permit requires the permittee to retain records associated with residuals disposal for a period
of 5 years. Within 3030days- 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, of the residuals removed from the septage tank,
3. Disinfection: Your system uses a tablet chlorination unit for disinfection of wastewater. The
chlorination tablet disinfection system provides effective disinfection and reduces harmful
bacteria from entering the environment. You are required to inspect the tablet chlorinator
weekly to ensure there is an adequate supply of tablets for continuous and proper operation. At
the time of inspection, the chlorination unit was located. 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 permit.
4. 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, Total Nitrogen, Ammonia Nitrogen and Phosphorous. At the time of
inspection, records were not provided showing the required monitoring was conducted.
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 November 1st, 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 a required is a
violation of NPDES General Permit NCG550000.
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

discharge pipe was clear of obstruction. Please ensure the outlet is always visible/maintained
and cleared of vegetation, soil, and leaves.
Please continue to periodically inspect and evaluate the wastewater spray irrigation system
components are properly maintained and operating as designed. Maintain all associated
operational records onsite for a period of three years as required by the subject permit.
If you have questions or comments about this inspection or the requirements to take
corrective action (if applicable), then please contact Jim Westcott at
