Dear Mr Dennis:
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection
conducted on 4/20/2016. The Compliance Evaluation Inspection was conducted by Trent Allen of the
Fayetteville Regional Office. The facility was found to be in Compliance with permit NC0028916. As a
reminder, preservation of the Waters of the State can only be achieved through consistent NPDES
Permit compliance.
Please refer to the enclosed inspection report for additional observations and comments. If you or your
staff have any questions, please call me at 910-433-3336.
. Sincerely,

Facility appeared to be clean and well maintained on the day of the inspection.
The DMR for the month of September 2015 was reviewed during the inspection with no issues noted in
transcription.
The thermometer in the influent and effluent samplers was outdated. Make sure to replace the
thermometers yearly, or calibrate them with a NIST certified thermometer.
The influent flow meter was calibrated on April 18, 2016 by D.J. Freeman.
