On July 16, 2018, Mitch Hayes from the Raleigh Regional Office visited your single-family residence
(SFR)wastewater treatment system to evaluate compliance with the above pen-nit to discharge wastewater.

dechlorination systems, have the effluent_sampledonce 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.

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

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 da s of receiet of this letter that states our elan for conectm• this deficient .
