Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit No.NCG550950
Durham County
Dear Mr. White:
On March 8, 2018, Ray Milosh 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 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.
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). 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.
D 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: Your Your system was installed after August 1, 2007, so must 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.
❑ 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. A
list of NC certified laboratories that provide this service was left at your residence during
the inspection. 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 done.
n 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 Ray Milosh 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.
