Robeson County
Dear Mr. Cummings:
Enclosed you will find a copy of the Compliance Evaluation Inspection (CEI) report for the routine
annual inspection that I performed on January 19, 2011 at the Town of Pembroke Wastewater Treatment
Plant, accompanied by Rhonda Locklear (ORC, WWTP), Jerry Brooks (Back -Up ORC), and Branyun
Bullard (WWTP Operator). - As part of the inspection, a tour. of the Wastewater Treatment Plant was
conducted. All observations are in Section D. Summary of Findings/Comments of this inspection report.
On the day of my inspection, the wastewater treatment plant appeared to be very well operated and
maintained, and it appeared to be in compliance with the NPDES permit. I appreciate the time and
professional courtesy that was extended by your staff during the inspection. No additional response is
necessary from your office to the DWQ-Fayetteville Regional Office concerning this CEI report. Please
contact me at [phone] if you have any questions or comments.
Sincerely,
Dale Lopez
Environmental Specialist
