Subject: Compliance Evaluation Inspection DEC 29 2017
134 Bergman Drive
Single Family Wastewater Treatment System Water Resources
Permit No. NCG550010 Permitting Section
Durham County
Dear Ms. Bergman:
On December 19, 2017, Cheng Zhang from the Raleigh Regional Office visited the single-family
residence (SFR) wastewater treatment system at 134 Bergman Drive in Durham County 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 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 vour plan for correctim, this deficiency. The work is to be completed within the next 3
month.
❑ 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). 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 recei )t of this letter that states your plan for correcting
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.

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 Ilan for correcting this deficiencv.
❑ 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.

analyzed once each year. See Part I (A) of your permit about his requirement. A list of NC
certified laboratories that provide this service was left at your residence during the inspection.
