Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit No.NCG550037
Durham County
Dear Mr. Derby: sr
On May 2, 2017, Andy Neal and Stephanie Goss 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.
❑ 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 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.
n 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.
❑ 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.
El 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

of receipt of this letter with a sketch or map.
