Subject: Compliance Evaluation Inspection DWR SECTION
Single Family Wastewater Treatment System
Permit No. NCG550123
Orange County
Dear Mr. Mays:
On May 13, 2015, Cheng Zhang from the Raleigh Regional Office visited the subject single-family
residence (SFR)wastewater treatment system to evaluate compliance with the above permit to discharge
wastewater. Your assistance 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 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 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 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 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. 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. Attached is a list of laboratories in NC certified to provide this
service. 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.
❑ Locations of treatment units are unknown.
❑ Other:
If you have questions or comments about this inspection or the requirements to take corrective action,
please contact Cheng Zhang 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.
Sincerely,
k/‘(t

The septic tank was last pumped on 1/9/2012. The permittee has a supply of correct chlorine tablets.
Tablets were observed in the chlorinator(no water in the chlorinator). It appears that there has been no
discharge from the end of the pipe for a long time,therefore not possible to sample.
