action(s) taken. Attach additional ghPatg if naraggary
The plant had Daily violations for BOD and Ammonia on the last 2 days of the month. As part of the Hurricane Florance Recovery Project, the SBRs were returned to automation the week of the 15th. Due to
the change from the manual operation to a more fluid automated operation we believe this may have contributed to the BOD some but mostly believe the redundant chlorine feed is more likely the cause and we
also observed an increase in the COD samples collected. The chlorine pumps have been temporarily linked to the post EQ pumps but the operators control was limited on the feed rate. We have worked with
the SCADA intergrator to fix this issue and the operators now have better control to adjust the feed rates. In additions, the chemical feed pumps for the SBR process were not linking properly to the operational
program which resulted in less than desired chemical feed to the SBR. Other adjustments for the down time of blowers and mixer pump have been adjusted to reduce idle time and better maintain dissolved
oxygen and mixing.We have notified the Wilmington Regional Office and will continue to update them on our progress and any further violations. The plant had no flow on the 11th due to the SBR inlet valve
breaking down which prevented the plant from running a batch on that day. The valve was repaired and returned to service.
