Dear Mr. Johnson:

Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit No. NCG551296
502 Scott King Rd SFR
Durham County
On September 12, 2019, Joan Schneier from the Raleigh Regional Office visited your single-
family residence (SFR) wastewater treatment system to evaluate compliance with the above
permit to discharge wastewater. Your assistance during the inspection was greatly appreciated.
The checked boxes below show what conditions were noted at your facility:
N Failure to analyze the effluent: The effluent that is discharged from your system
must be analyzed once each year. See Part I(A) of your permit about his requirement.
Make arrangements for sampling to be carried out within the next 3 months and submit
results to this office within 3 weeks after the sampling has been conducted. You can do
your own sampling but must have the samples analyzed by a state certified lab, which
will require that you use its bottles. A list of certified laboratories who may do these type
analyses is attached. Please call the lab for details. Alternately, please check the Yellow
Pages for Environmental Consultants who may do the sampling, but they also have to use
a certified lab for analysis.
® Other: You have an Advantex system, which is highly effective but requires periodic
maintenance by trained operators. Please resume a maintenance contract, as soon as you
are able.
If you have questions or comments about this inspection or the requirements to take corrective
action, please contact Joan Schneier or me at 919-791-4200 or joan.schneier c ncdenr.gov.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The system consists of a septic tank, Advantex AX-20 RT pod with self-contained cloth filters, recirc
pump, and UV. There is gravity flow to the riprapped outfall with vermin grate to the road ditch on 5alix
Dr. The system was installed in August, 2014 to replace a failing sand filter. Bob ,Johnson assisted with
the inspection.
The septic covers were opened and the efflent filter partly cleaned by repeated dunking in the first
chamber.
The pod had two good sprayers but the filter seemed a bid sludgy. The last maintenance was in Dec
2018 by McFarland, but the system is presently not covered by a contract. The owner indicated that he
would resume a maintenance contract in the future. The panel was repaired in December, 2018 after a
lightning strike.
The high water alarms came on after time delay, although the audio was weak. The UV bulb worked.
No samples have been taken lately but the November 2016 showed less than 4 for all three
parameters, which is excellent.
No problems were seen in the ditch area.
Non -compliant only due to failure to sample.
Access and Location Notes:
3116 inch Alien Wrench needed for lank covers, 112 inch socket for pod.
The outfali is under the holly bushes, just north of the gate on 5alix Dr.
