Robeson County
Dear Mr. Lowry:
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on
July 16, 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
NC0027103. The cooperation of Mrs. Rhonda Locklear, Grade IV 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.
• Records and log books are neat, well kept, and up to date.
• Laboratory records for February 2013 were reviewed and compared to the monthly DMR. No transcription
errors were found at that time.
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.
Sincerely,
Mark Brantley
