A. (2.) TEMPORARY MEANS OF DISINFECTION [G. S. 143-215.1(b)]
In the event that the wastewater treatment plant's ultraviolet (UV) disinfection system should fail,

If chlorine compounds are used as temporary means of disinfection, the total residual chlorine (TRC)
concentration of the effluent must be monitored on a daily basis while this method of disinfection is in use and
values must be reported on the discharge monitoring report. TRC in the effluent may not exceed 17 µg/L;
therefore, dechlorination methods may also _:)e necessary to ensure'protection of water quality in the receiving
ctrPam
Use of a disinfection system other than the permitted
