Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit No.NCG550799
Durham County
Dear Mr.Williams:
On July 16, 2018, Mitch Hayes 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:
(l 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 30 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 or are wrong You are responsible for always having chlorine
tablets and dechlorination tablets(if a required part of your system)m place.They must be the kind
for wastewater treatment and not for swimming pools.
❑ 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.

E 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.
[1 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: Right of way to the discharge point needs to be maintained.
If you have questions or comments about this inspection or the requirements to take corrective action,please
contact Mitch Hayes 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.
