Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
A routine compliance inspection of the Towm of Newport WWTP was conducted on August 20, 2019.
The purpose of the evaluation was to verify that the facility is operating in compliance with the
conditions and limitations specified in Permit NC0021555. Scotty Rollins, ORC, Cody McNamara,
operator and Richard Elliott, EPA Region IV representative, were present during the inspection.
This facility averages 600,000 gpd of the permitted 1.2 MG flow. The permit has been expired since
July 31, 2017, but a new permit is currently in draft form. The draft has several changes from the
existing permit, to include the addition of quarterly monitoring for bromodichloromethane, lead, copper
and hardness. The Town has provided comments and questions to the Division in regards to the
bromodichloromethane monitoring. It was recommended by the EPA representative to investigate the
possible sources of this chemical.
The facility performs various process control analyses and tracks daily operations on a data check
sheet. Pump stations throughout the plant are connected to the Missions telemetry communication
system. A review of records, since the last inspection in 2017, showed no violations issued.
The facility is compliant with the NPDES Permit NC0021555. Please review the comment sections of
the inspection report for more details.
