residence (SFR) wastewater treatment system to evaluate compliance with the above pen -nit to

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 cominended

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 vour Ulan for correctnza this deficienev 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.
