Dear Mr. Brobst:
William G. Ross, Jr., Secretary
Alan Klimek, P.E., Director
Division of Water Quality
Enclosed is a copy of the Compliance Evaluation Inspection conducted March 14, 2003.
As part of the inspection a tour of the Wastewater Treatment Plant was conducted. All observations
and recommendations are in Part D. Summary of Findings/Comments of this inspection report. The
cooperation of Mr. Delmo Frye, Grade IV ORC, Mr. Jeffery Corder, Grade IV Backup ORC, and
Ms. Lillian Stephens, Laboratory Supervisor was appreciated. During the inspection a copy of the
NPDES Compliance Reminders were reviewed and left with facility staff. As a reminder
preservation of the Waters of the State can .only be acquired through consistent NPDES permit
compliance.
Please review the attached report. If you or your staff have any questions do not hesitate to
contact me at 910-486-1541.
Sincerely,
Belinda S. Henson
Environmental Chemist

The automatic bar screen appeared to be operational. Screenings are disposed of through the Uwharrie
Environmental landfill.
The facility continues to accept septage from various sites. The septage is discharged into a manhole at
the headworks of the plant.
The grit removal system was operational but problems still occur with the pump clogging as per staff.

The facility does the following process control: F,/M ratios, sludge ages, MLSS, wasting rates and etc.
Facility staff generate work orders when maintenance is needed and regular preventive maintenance is also
tracked through a computer system.
A compliance evaluation report for the period January 2002 through December 2002 did not reveal any NPDES
permit limt violations.

temperature range of samples during storage and stored samples extracts, is 1.0 - 4.4 degrees C.
Both blowers at the headworks of the plant appeared to be operational.
The facility has two (2) primary clarifiers. They appeared to be operating adequately.
The first stage aeration basin was operational with Mixed Liquor Suspended Solids (MLSS) results of 2700
mg/L.. The MLSS is monitored weekly by the onsite certified laboratory and each day by the Royce Model
711 meter. The third bay (section) was offline due to repairs at the time of the inspection.
The two (2) intermediate clarifiers appeared to be operating adequately.
The second stage aeration basin was opearational with MLSS results of 2300 mg/L. Lime is added to this
area when additional treatment is needed. Polymer is added at the end of the aeration to assist with
solids settling. There appeared to be a small leak from the polymer feed system. As per Mr. Frye, plans
are to repair this as soon as possible.
The two (2) final clarifiers appeared to be operating adequately. The sludge depth on #1 was 1.foot with
a tank depth of 15 feet. #2 was not checked at the time of the inspection due to the location of the
skimmer arm. ***THE RAILINGS AND THE CATWALKS OF THE CLARIFIERS APPEARED TO HAVE SOME (NOT EXCESSIVE)
PAINT WORN FROM THE SURFACES. IT WOULD BE A RECOMMENDATION IN THE NEAR FUTURE TO REPAINT THESE AREAS TO
ELIMINATE FURTHER COSTS IN THE'FUTURE.**** -
The effluent is disinfected with chlorine. ***A RECOMMENDATION WOULD BE TO INCORPORATE A FLOW
PROPORTIONAL CHLORINE FEED SYSTEM TO ASSIST WITH CONSISTENT DISINFECTION AND COULD BE A COST SAVINGS TO
THE COUNTY.*** The sludge depth was less than (>) 1 foot in the chlorine contact tank. A
recommendation is when the sludge depth reaches >/= 1 foot, then the chlorine contact tank should be
cleaned.
The effluent is dechlorinated with sulfur dioxide.
The temperature of the effluent composite sampler refrigerator was 1 degree C at the time of the
inspection. The sampler is flow proportional based on pulses, the more flow the faster the pump will
operate to collect sample.
The DAF unit is not utilized at this time since it is not needed. Solids are consistently wasted from
the system to the anaerobic digesters. Sludge from the primary, intermediate and final clarifiers flow
to the primary digester where it is heated up to 97 degrees C and travels to the top of the digester.
The by product methane from the process is used to warm the sludge. New heaters for sludge had been
installed since the last inspection dated December 20, 2001 After the sludge is heated it is pumped to
the secondary digester where it goes to the drying beds. From the drying beds it is diposed of in the
Uwharrie Environmental Landfill. The facility has 36 drying beds. Some (not excessive) vegetative
growth was noted in some of the drying beds. The growth should be removed to ensure proper maintenance of
the drying beds. The facility has -a permit (#WQ0018018) to land apply sludge but presently the facility
does not utilize it.
The influent flow meter was calibrated January.29, 2003 by Instrumental Services, Inc.
The facility has a certified laboratory on site which analyzes most NPDES required parameters. All other
parameters are analyzed by the commercial laboratory TBL. A brief inspection of the laboratory was
completed and found to be very well organized and clean.
Laboratory records were reviewed for the months of March and June 2002 and compared to Discharge
Monitoring Reports (DMRs). All records reviewed appeared to be accurate and very. well organized.
