Sullins Dee Freeman Governor Director Secretary March 30, 2010 McDuffiue Cummings, Town Manager Town of Pembroke P.O. Box 866 Pembroke, NC 283720866 SUBJECT: March 9, 2010 Compliance Evaluation Inspection Town of Pembroke Pembroke WWTP Permit No: NC0027103 Robeson County Dear Mr. Cummings: Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on March 9, 2010. The Compliance Evaluation Inspection was conducted by Mark Brantley, Environmental Chemist, of the.Fayetteville Regional Office. The cooperation of Rhonda Locklear, Grade IV ORC, and Jerry Brooks, back- up ORC, was greatly appreciated. The facility was found to be in Compliance with permit NC0027103. 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. • The Division of Water Quality encourages the town to replace the existing dissolved oxygen probes on the oxidation ditches with new updated probes. Installing new dissolved oxygen probes can help the facility reduce wear and tear on equipment, repair costs, and electrical costs by controlling the brush aerators. The probes would allow the aerators to run only when needed. 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.
