Laurinburg NC 28353 SUBJECT: August 14, 2013 Compliance Evaluation Inspection City of Laurinburg Leith Creek WWTP Permit No: NC0020656 Scotland County Dear Mr. Ellis: Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on August 14, 2013. 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, Grade IV 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 • Facility was clean and neat in appearance at the time of the inspection. •. Maintenance records, log books, and laboratory records were well kept and in order. • Laboratory records for the month of February 2013 were compared to the monthly DMR and no data transcription errors were found. Please refer to the enclosed inspection report for additional observations and comments. If you or your staff have any questions, please call me at 910-433-3327.
