Single Family Wastewater Treatment System
Permit No. NCG550847
Durham County
Dear Sir or Madam:
On October 25, 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:
n 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.
n 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.
❑ 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.
n 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. 4
A pumping company can check the status periodically and determine when pumping is
required.
[,I 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-r-eceipt-of-this_letter_with_a_sketch_o_rmap_Please locate the discharge
pipe.
® Other: Please fill out the attached change of ownership forms and mail to the
address on the form, within 30 days.
Excess vegetation needs to be cleared from the sand filter area and the area kept
open to prevent root invasion and possible damage.
A path should be cleared to the chlorinator tube near the fence and tablets stocked
regularly.
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,

Section D.Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
the system consists of a septic tank, sand filter, chlorinator, and discharge pipe.
The property has been sold to the Research Triangle Regional Public Transit Authority, aka Go Transit.
It is managed by"Acorn &Oak".
The current tenants had no knowledge of the septic system and have been there about a year.
The septic tank and sand filter were not located and heavy vegetation in the back yard prevented a
search.
The chlorinator is straight downhill from the southeast corner of the house and close to the fence on
the edge of the sewer line right-of-way (apparently built about 2010 in conjunction with nearby
development).
A search for the outfall pipe was unsucessful. No residuals or unusual wet spots were found in the
area.
