Dear Mr. Ellis:
Donald R. van der Vaart
Secretary
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection
conducted on 5/28/2015. The Compliance Evaluation Inspection was conducted by Mark Brantley,
Environmental Senior Specialist, of the Fayetteville Regional Office. The facility was found to be in
Compliance with permit NC0020656. The cooperation of Mr. Ricky Odum, Facility Back-up ORC, was
greatly appreciated. As a reminder, preservation of the Waters of the State can only be achieved
through consistent NPDES Permit compliance.
Comments
> The facility was clean and neat in appearance at the time of the inspection. During the walk
through portion of the inspection the effluent was observed to be clear and free of solids.
> Maintenance records and log books were neat and up to date.
> Laboratory records for the month ofJanuary 2015 were reviewed. Two very minor transcription•
errors were found but they did not affect permit compliance. Please be careful when entering
data into the eDMR database to ensure proper results are reported.
