Subject: Compliance Evaluation Inspection
5715 Cascade Drive SFR
Single Family Wastewater Treatment System
Permit No. NCG550230
Orange County
Dear Mr. & Mrs. Kellum:
On December 4, 2018, 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. The checked boxes below show what conditions were noted at
your facility:
❑ In compliance: You are reminded to regularly maintain the chlorine disinfection
system, have the effluent sampled once a year, and have the septic tank pumped out every
3 to 5 years. Your good record of operation and meeting the permit requirements is
highly commended.
❑ Your home is improperly plumbed: Some of the wastewater discharges are going
directly to the environment without first passing through the treatment system. This must
be corrected immediately. Please submit a schedule to this office within 20 days of
receipt of this letter that states your plan for correcting this deficiency. The work is to be
completed within the next 3 months.
n Disinfection: Your system is lacking disinfection, either chlorine tablets or a UV light
system. New rules put into place on August 1, 2007 require all SFR systems to have a
means of disinfection (and dechlorination when chlorine tablets are used to disinfect, if
the system was installed since that date).
❑ Treatment tablets missing or are wrong kind: You are responsible for always
having chlorine tablets in place. They must be the kind for wastewater treatment and not
for swimming pools.
❑ Dechlorination: Your system was installed after August 1, 2007, so must have a
means of dechlorination located downstream of the chlorinator and its contact chamber.

See Disinfection paragraph above. Please submit a schedule to this office within 20
calendar days of receipt of this letter stating your plan for correcting this deficiency.
❑ Pumping the septic tank: The septic tank should be pumped out every 3 to 5 years.
A pumping company can check the status periodically and determine when pumping is
required.
El 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.
® Locations of treatment units are unknown: Determine this and report to this office
within 30 days of receipt of this letter with a sketch or map.
® Other: Sample the effluent, as stated above, if there is flow out of the outfall pipe.
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. Licensed plumbers should be used
to make plumbing changes within your home. Contractors for installing disinfection or other
equipment may be found in the Yellow Pages under Environmental Consultants.
Sincerely, A]

Section D.Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
The system consists of a septic tank, sand filter, chlinator, contact tank, and outfall.
This was an unannounced inspection and no one was home.
The uppermost concrete riser lid was assumed to be the septic tank and not opened due to weight.
The owner called back on 12/13 and said that the septic tank was pumped out on 8/27/2018 and is
done-every-5-years. —
The chlorinator was not positively located.
Several concrete riser lids were opened and contained reasonably clear liquid
The outfall was not located and the backyard is very rocky, descending to a substantial perennial
stream.
A diligent search of the backyard did not show any problems.
Contact information and a list of tablet suppliers was left in the front door.
Location notes:
The top riser is behind the holly bushes. Risers near the south neighboring driveway are also part of
this system and near the sand filter. The owner said that the cascade aerator is about halfway down
the slope but has little or no output.
