Subject: Compliance Evaluation Inspection
811 Valmet Dr SFR
Permit No. NCG551633
Durham County
On February 14, 2019, Joan Schneier from the Raleigh Regional Office visited your single-
family residence CSFR) 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
system, 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. Thework 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).
® Treatment tablets missing or are wrong kind: You are responsible for always
having chlorine and dechlorination tablets 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.
M 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.
M 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. Make arrangements for sampling to be carried out within the next 3
months,and submit results to this office within 3 weeks after the-saml2linghas been
conducted.
❑ 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. Please locate the
discharge pipe.
® Other: Tablets were jammed in the chlorinator tubes and not in contact with the
effluent. Please have these cleaned out, using proper hand and eye protection, and
restock with no more than 2 or 3 tablets per tube.
Please stock dechlor tablets at about the same rate as the chlorine tablets in the
second set of tubes.
Please do not sample for several weeks after pumping out the septic tank.
If you have questions or comments about this inspection or the requirements to take corrective
action, please contact Joan Schneier 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.
