Dear Permittee: Permitting Section
The North Carolina Division of Water Resources conducted an inspection of the Dunn WWTP
on 5/15/2018. This inspection was conducted to verify that the facility is operating in
compliance with the conditions and limitations specified in NPDES WW Permit No. NC0043176.
The findings and comments noted during this inspection are provided in the enclosed copy of
the inspection report entitled "Compliance Inspection Report". The cooperation of Mrs. Donrie
Dukes, facility ORC, was greatly appreciated.
Comments
• Facility was clean and neat in appearance at the time of the inspection.
• The Division of Water Resource's records has Ronald Autry listed as the city manager.
Please complete and return the enclosed change of ownership form with the current city
manager's, Mr. Steven Neuschafer, information.
• The influent sampler was out of service because it was not cooling properly.- Repairs__
were being made during the inspection. Samples were being collected by hand until
sampler was repaired.
• Several air leaks for the air distribution system were noted during the inspection. The
division understands that only limited repairs are being made at this time because an
upgrade to the aeration system is scheduled to begin in the near future.
• A laboratory inspection and records review were not conducted because the North
Carolina DWR Laboratory Certification Section performed their inspection on January 31,
2018.
