Dear Mr. Parnell:
Enclosed is a copy of the Compliance Evaluation Inspection conducted
February 22, 2000.
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 priority of all wastewater
treatment facilities should be complete compliance with the NPDES permit which
will ensure the best quality effluent discharged to our receiving streams.
Please review the attached report. If you or your staff have any questions
do not hesitate to contact me at 910-486-1541.

Section D: Summary of_Findings/Comments:
1. The manual bar screen was operational. All screenings are disposed of through the county landfill
monthly.
2. The removal of sand from the oxidation ditches was completed since the last inspection dated July
9, 1999. The sand was dried on the drying beds and disposed of through the county landfill.
3. The rotor in oxidation ditch #1 appeared to be operational. In oxidation ditch #2, the rotor was not
operational. As communicated by the "ORC" repairs are in the process of being completed.
Catwalks, railings and power box covers located at the oxidation ditches appeared to have worn
paint from the surface of the metal. Painting of these surfaces are needed at this time.
4. Clarifier #1 was operational with some pin floc floating over the weirs but not excessively. Clarifier
#2 was not operating due to oxidation ditch #2 not in operation. A usable sludge judge was not on
site at the time of the. inspection. A strong recommendation from our office is to purchase a •
sludge judge immediately to assist in operations of this facility Catwalks and railings appeared
to have worn paint on the surface. Repairs should be completed in the near future before major
repairs are necessary.
5. The chlorine contact tank appeared to have some floatable debris but not excessive. The floatables
are removed with a net daily and properly disposed of.
6. The effluent appeared to be visably free of solids.
7. The effluent outfall has not been located by facility staff. A suggestion was made to review "As
Built" engineering drawings to assist in location. All facilities should be able to inspect their
outfalls from time to time.
8. The sludge digester has not been used in years as communicated by facility staff. The four sand
drying beds did not appear to have any sludge in them. Some vegetative growth appeared to be in
the drying beds. All vegetative growth should be removed to enhance sludge drying when applied
to the beds. Sludge is not normally wasted from the clarifiers but recirculated into the oxidation
ditch for treatment again.
9. This facility has backup power when needed. Generator operation is recorded in a log book located
in the panel door. The tank which contains diesel fuel used to power the generator has been placed
in a new support brace which appears to be much safer than the previous one. The tank appeared
to have many areas where the paint has worn from the surface. Painting of these surfaces could
eliminate major repairs in the future.
10. Maintenance records were not available at the time of the inspection Maintenance and
operational records should be maintained to assist in proper operation of the facility to ensure
NPDES permit compliance,
11. The effluent flow meter was calibrated February 7, 2000 by "Carolina Technical Services, Inc." It
is advisable that the flow meter calibration document contain the % error before and after calibration
in the future by the technician.
12. The NPDES permit was available upon request.

-continued-
13. The following NPDES permit required parameters are analyzed by facility staff: pH, Temperature,
Dissolved Oxygen and Chlorine Residual. All other parameters are analyzed by "The Best Lab
(TBL)" formally Test America.
14. Laboratory records were reviewed for the months June through October 1999 and compared to
Discharge Monitoring Reports (DMR). All reviewed records appeared to be accurate.
15. A compliance evaluation analysis report for the period January through December 1999 revealed
the following violations:
January - Toxicity (monthly violation)
February - Flow (monthly violation)
March - Fecal Coliform (monthly violation)
May - TSS (monthly violation)
July - Toxicity (monthly violation)
September - Flow, Ammonia, & Fecal Coliform (monthly violation)
October - Flow, Fecal Coliform & Toxicity (monthly violation)
November - Fecal Coliform (monthly violation)
December - Fecal Coliform (monthly violation).
16. The following Notice of Violations were sent to this facility, from our office:
January - 2 Fecal Coliform ( weekly violations), Toxicity (monthly violation)
February - 2 Fecal Coliform (weekly violations), Flow (daily violation)
March - 4 Fecal Coliform ( weekly violation) & 1 Fecal Coliforr (monthly violation)
June - Fecal Coliform (weekly violation)
July - Toxicity (monthly violation)
August - 3 Fecal Coliform (weekly violations)
17. As a reminder as'per our Administrative Code Section: 15A NCAC 2B .0506(b)(3)(F)(i)-the date
on which collection of composite, samples is commenced or data shall be entered onto the
monitoring report form on the date that has the greater number of hours in it. The following
examples will assist you in understanding the reporting date:
A. If the composite sample is started on Tuesday, March 7, 2000 at 9:OOAM and the sample
is withdrawn from the composite sampler on Wednesday; March 8, 2000 at 9:OOAM; the
day with the greater number of hours in it is Tuesday, March 7, 2000.
B. If the composite sample is started on Tuesday, March 7, 2000 at 6:OOPM and the sample is
withdrawn from the composite sampler on Wednesday, March 8, 2000 at 6:OOPM; the day
with the greater number of hours in it is Wednesday, March 8, 2000.
