Acting Director
Division of Water Quality
Enclosed is a copy of the Compliance Evaluation Inspection conducted December 20, 2001.
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, 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,

Section D: Summary of Findings/Comments:
1. The County continues to contract the operations of the wastewater treatment plant to "American
Water Services".
2,
The waste stream. is made up of domestic and industrial. The facility has a pretreatment program
which has the following Significant Industrial Users (BTUs): Intec, Ingersoll Rand, and Erico.
Wastewater from Camp McCall is received into the headworks of the facility by one designated
pipe.
3. The automatic bar screen appeared to be operational. It operates on a timer or a float system.
Screenings are disposed of through the Uwharrie Environmental landfill.
• 4. The facility accepts septage-from various sites. The septage is discharged into a manhole at the
headworks of the plant.
5. The grit removal. system was operational.
6. The influent composite sampler temperature was 1 degree C. The acceptable temperature range of
samples during storage and stored sample extracts, is 1.0 - 4.4 degrees C.
7 Two blowers are used at the headworks of the plant to add aeration. One blower is normally all that
is needed for post aeration.
8. The facility has two (2)_ primary clarifiers. One (1) was operational and the other was down for
repairs.
9. The first stage aeration basin appeared to be operational. This component of treatment has 4
compartments. Two' compartments were utilized for treating the wastewater at the time of the
inspection. The Mixed Liquor Suspended Solids (MLSS) results on the day of the inspection was
1950 mg/L. The Royce Model 711 is used to analyze MLSS.
10. The two (2) intermediate clarifiers appeared to be operating adequately.
11. The second stage aeration basin appeared to be operating adequately. The MLSS .results on the day
of the inspection was 1500 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.
12. The two (2) final,clarifiers appeared to be operational. The sludge depths in each clarifier was less
than 1 foot with a tank depth of 15 feet. .
13. The effluent is disinfected with chlorine. The chlorine contact tank appeared to be clean.
14. Sulfur Dioxide is used to dechlorinate the effluent.

January 2, 2002
15. The effluent appeared to be free of solids. The effluent outfall was easily accessible.
16. The effluent composite sampler refrigerator temperature was 1 degree C. The effluent composite
sampler is not flow proportional at the present time due to an electical storm which caused it's
malfunction. Repairs should be made immediately to continue effluent flow proportional
sampling.
17. The DAP units are not utilized at this time.
18. Wasting from the clarifiers is on the average of 50,000 gallons/day.
19. Sludge from the primary, intermediate and final clarifiers flows to the primary digester where it is
heated up to 99 degrees Celsius and travels to the top of the digester. 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
disposed of in the Uwhan-ie Environmental Landfill. The facility has 36 drying beds. Some
vegetative growth was noted in some of the drying beds. These areas should be cleaned and
maintained to ensure proper drying of the sludge. The facility has a permit (#WQ0018018) to land
apply sludge effective March 30, 2001.
. 20. The influent flow meter is used in reporting on the Discharge Monitoring Reports (DMRs). The
meter was calibrated August 10, 2001 by "Carolina Technical Services, Inc". As stated in the
calibration report the % error is 0.
21.
The facility has a certified laboratory on site which analyzes most NPDES permit required
parameters. All other parameters are analyzed by the commercial laboratory "TBL".
22. Laboratory records were reviewed for the months March, April.andMay 2001 and compared to
DMRs. All reviewed data appeared to be accurately reported.

Dear Ms Henson:
'JIAN 3 12002
In response to your letter dated January 2, 2002 we would like to provide you with a response in
regard to a plan of action on item #16, "the composite sampler is currently not flow proportional".
We currently have acquired the services of KM Industrial Electric, LLC to correct this problem.
They have thoroughly investigated the problem and has assured us the problem would be corrected no later
than February 15, 2002 (see attached).
We would also like to bring to your attention a typographical error in item # 19 that states
"Primary digester where it is heated up to 99 degrees Celsius". The unit should be Fahrenheit
instead of Celsius.
If you have any other questions please feel free to contact us at 1-910-281-3146.
Thank You

Attention: James Frye
Auer testing the wiring, to the Plant Effluent Sampler it is my recommendation that this
circuit be replaced. Circuit is defective and must be replaced to resolve current condition.
This will be repair by February 15, 2002
