Dear Mr. and Ms. Bergman:
On April 11,2018 Mitch Hayes and Andy Neal 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. 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 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 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.
