Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
Permit No.NCG550073
Chatham County
Dear Mr. Andrews:
On February 26, 2016 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.
❑ 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.

f
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.
❑ 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.
n Other:
If you have questions or comments about this inspection or the requirements to take corrective
action, please contact the inspector 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.
Sincerely,

Section D:Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
I could not locate the ST. The PT was locked. The alarm switch worked. There were no CI or de CI
tabs present. There was no sign of failure of the sand filter. I could not locate the outfall.
Brain Andrews called. He bought the house from Heather Aloor. I will send him a change of ownership
form. He says the ST is in the front yard near the driveway and the outfall is at the ditch by the road
with rip rap. He says he checks the chlorinator every month and a half. His tablets are degrading and
he will buy new ones. He had the chlorinator and dechlorinator repaired when he bought the house and
had the ST tank checked. It was last pumped in 2012. He is considering getting a food disposal. I told
him that solids will likely build up faster and to have the tank checked more frequently. I suggested
having a riser installed over the ST to make for easier access.
