Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit No. NCG551716
Durham County
Dear Ms. Hall:
On January 22, 2019, Jeremiah Dow and Erin Deck from the Raleigh Regional Office visited your single-
family residence (SFR) wastewater treatment system to evaluate compliance with the above permit to
discharge wastewater. Ms. Hall's assistance during a follow-up telephone conversation was greatly
appreciated. The checked boxes below show what conditions were noted at your facility:
❑ In compliance: You are reminded to regularly maintain the chlorine disinfection and
dechlorination systems, 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.
❑ Disinfection: Your system is Iacking 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). Since your system had no disinfection, the installation is to include a
chlorine tablet dispenser, a contact chamber capable of providing a minimum 30 minute contact
time, and another tablet dispenser that will hold dechlorination tablets. Please submit a schedule
to this office within 20 calendar days of receipt of this Ietter that states your Ulan for correcten
this deficiency.
® Treatment tablets missing or are wrong kind: You are responsible for always having
chlorine tablets and dechlorination tablets (if a required part of your system) in place. They must

be the kind for wastewater treatment and not for swimming pools. Unable to open treatment
units at the time of the inspection. During our telephone conversation Ms. Hail stated that
it had been approximately six months since tablets had been added. Ms. Hall was
recommended to check the units and add tablets, and to increase the frequency with which
the chlorinator and dechlorinator are checked.
❑ 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, our 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.
2 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. Please make
arrangements for sampling to be carried out within 3 months and submit results to this office
within 3 weeks after the sampling has been done.
❑ 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:
If you have questions or comments about this inspection or the requirements to take corrective action,
please contact Jeremiah Dow at 919-7914200. 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.
