Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit "No. NCG550724
Durham County
Ms. Mason:
On March 29, 2012 Tom Ascenzo 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:
❑ 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.
❑ 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 receipt of this letter that states your plan for correcting
this deficiency.
® Treatment tablets missing. 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. One

❑ 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 statingyourplan for correcting this deficiency.
❑ Pumping the septic tank. You are to have the septic tank pumped out every 3 to 5 years. A
pumping company can check the status periodically and determine when pumping is required.
Failure to analyze the effluent from your system once each year. See Part I(A) of your
permit about his requirement. At the time of inspection a list of laboratories in NC certified to
provide this service was provided to you. 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

❑ 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.

unit at 919-807-6391 upon receipt of this letter. Refer to handout to obtain lab analysis and
proper chlorine tablets purchase.
