Dear Mr. Lockhart:
Enclosed please find a copy of the Compliance Inspection Report from the inspection conducted on August 18,
2015 by Trent Allen of the Fayetteville Regional Office. Also, I would like to thank Mr. Sam -Stewart, Mr. Ried
McAlister, and Mr. Alex Turner for their time and cooperation during the inspection. The facility was found to
be in Compliance with permit NC0021504. As a reminder, preservation of the Waters of the State can only be
achieved through consistent NPDES Permit compliance.
Please refer to the enclosed inspection report for additional observations and comments. If you or your staff has
any questions, please call me at 910-433-3336.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Facility is in the middle of an upgrade. New head works and a clarifier are being built, and should be
completed by the end of the year.
The DMR for the month of February 2015 was compared to the lab sheets, and the two appear to
match. Records appeared to be in good order.
The crack in the digester was filled with hydraulic cement, but still appears to be leaking. It is
suggested that the Town have a structural engineer evaluate the digester tank to determine what needs
to be done to repair the crack.
The Town is in the process of starting a pretreatment program.
