Permit No: NC0028916
Montgomery County
Dear Mr. Walls:
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted
on July 22, 2003. The Compliance Evaluation Inspection was conducted by Belinda S Henson of the
Fayetteville Regional Office. The facility was found to be in Compliance with permit NC0028916. The
cooperation of Mr. Stephen Jarman, Grade III ORC was appreciated. As a reminder preservation of the
Waters of the State can only be acquired through consistent NPDES permit compliance.
Please refer to the enclosed inspection report for'additional observations and comments. If you or your staff
have any questions, please call me at 910-486-1541.
Sincerely,
4.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The contract company Meritech, Inc operated this facility at the time of the inspection. As of August 1,
2003, the Town will begin operation of the wastewater treatment plant.
A manual bar screen and a rotameter are used to remove trash and debris at the headworks of the plant.
The rotameter operates by an ultrasonic sensor that senses the flow depth and automatically operates.
A11 screenings are disposed of through the Uwharrie Environmental Landfill.

operational. It is operated twice a day. All, grit is .disposed of through the Uwharrie Environmental
Landfill.
Caustic is added to the influent for pH adjustment. Candor Hosiery is moving some of their operation to
the Town of Robbins facility which has caused a decrease in facility influent pH as per staff.
The ORC for this facility is Stephen Jarman, Grade III operator and Pat Merritt is the Backup Operator.
**AS A REMINDER THE NEW ORC AND BACKUP OPERATOR MUST COMPLETE AN APPLICATION AND SUBMIT TO TECHNICAL
TRAINING AND CERTIFICATION UNIT IN RALEIGH AND CC THE FAYETTEVILLE REGIONAL OFFICE.**
The influent composite sampler refrigerator temperature was 3.5 degrees Celsius. The acceptable
temperature range of samples during storage and for stored sample extracts, is 1.0 to 4.4 degrees
Celsius. Ref: Federal Register, July 1, 1995; 40 CFR 136; Table II.'
The oxidation ditches appeared to be operating efficiently. The ditches operate in series. An anoxic
zone is used to reduce nitrogen and phosphorus. The facility analyzes Mixed Liquor Suspended Solids
(MLSS) on.a monthly basis. The most recent results are approximately 3500 mg/L.

The clarifiers sludge depths were the following: Clarifier 41: 1 foot with a tank depth of mil feet and
Clarifier f2: 1.5 feet with a tank depth of 11 feet.
The'facility has completed installation of the UV. system for disinfection and has been on line for
approximately one month. The facility continues to add chlorine until the UV system testing has been
completed. The UV system has 2 banks with 4 bulbs per bank. The system is self cleaning which injects
a soap•cleaner and then wipers are activated. The cleaning occurs every 4 hours. Grease balls are
manually removed from the effluent before it reaches the UV system. Grease balls are removed by a net
and placed on a tray and disposed of through the county landfill. Plans are to utilize chlorine gas as a
backup system for disinfection. Plans are to relocate the effluent flow from the UV system and to
directly discharge to the stream and bypass the chlorine contact tank.
The effluent appeared to be free of solids.
The effluent composite sampler refrigerator temperature was 0.5 degrees Celsius. The tubing was clean
and adequately maintained.
The effluent flow meter Milltronics OCM III was calibrated July 16, 2003 by facility staff.
The digester appeared to be operating adequately. The sludge holding tank appeared to have less than 1
foot in it. A land application event had occurred recently and the contract company Synagro had
basically emptied the tank. The facility normally wastes 50-60 inches/week which is approximately 48,000
gallons. Biosolids are land applied under permit # WQ0001240.
Two lagoons are located on site. The largest lagoon is used as a equalizing lagoon for high flows. The
smaller lagoon is no longer utilized and the Town is in the process of filling it in.
The following NPDES permit required parameters are analyzed by facility staff: pH, Temperature,
Dissolved Oxygen and Chlorine Residual under field parameter certification # 136. All other required
parameters are analyzed by Meritech, Inc.
Laboratory records were reviewed for the month February 2003 and compared to Discharge Monitoring Reports
(DMR). All records reviewed appeared to be accurate.
A compliance evaluation for the period April 2002 through April 2003 did not reveal any monthly
violations. The facility should be commended for their continued compliance of their NPDES permit.
