Enclosed is a copy of the Compliance Evaluation -Inspection conducted January 19, 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
priority of all -wastewater treatment facilities should be complete compliance with the NPDES permit
which will ensurethe bestquality effluent discharged to ' our receiving streams. To maintain
consistent compliance, ""process control testing" is highly recommended.
Please review the attached report. If you or your staff have any questions.
do not hesitate to contact me at 910-486-1541.
Sincerely,
Don Register-"

Section ID: Summary of Findings/Comments:
1. The manual bar screen was operational. All screenings are disposed of through the county landfill.
2. The Equalization (EQ) Basin assists in stabilization of wastewater before it flows to the oxidation ditch.
Return sludge from the clarifier is added to the basin. A recommendation for the (EQ) basin pump
discharge box was to increase slots in the baffle plate to allow further adjustment to maintain a constant
flow 24 hours/day through the plant.
3. The oxidation ditch appeared to be adequately treating the wastewater. The following parts for the brush
aerator are not on site: spare brush, bearing, gearbox or motor. A recommendation is to check the lead
time for replacement parts since this is the heart of the treatment process.
4. The clarifier appeared clear as it flowed over the weirs. The sludge depth appeared to be approximately
eight (8) feet with a tank depth of ten (10) feet.
5. The tertiary filters were observed to be operational with some grease balls floating on the surface. The
grease balls are skimmed from the water surface each day and properly disposed of.
Ultraviolet light is used as disinfection. Ultraviolet light lamps are cleaned every 2-3 weeks. An
intensity lamp indicator revealed a reading of three(3) with _a range of 0-7. Zero (0) means no
disinfection occurring.
The effluent appeared to be free of solids.
8. The effluent outfall was not easily accessible due to falling of trees from previous storms. The effluent
outfall should be accessible to monitor to assist with preserving our receiving stream.
9. The Aerobic Digester was observed to be operational. A quantity of up to 10,000 gallons of sludge is
wasted weekly. Sludge is land applied monthly to permitted land. An amount of 7 '/z acres surrounding
the wastewater facility is owned by the town and this area is used for sludge disposal. This facility has
a total of 44 '/Z acres permitted for land application of sludge. The "ORC" is responsible for
implementing the land application permit.
10. The effluent flow meter was calibrated September 2000 by Instrumentation Services, Inc. It is advisable
that the flow meter calibration document contain the % error before and after calibration in the future
by the technician.
11. The following NPDES permit required parameters are analyzed on site by facility staff: pH,
Temperature, Dissolved Oxygen. All other required parameters are analyzed by a contract laboratory
"Vann Laboratories."
12. A compliance evaluation analysis report for the period January through December 2000 revealed
monthly violations. Monthly violations for BOD and Ammonia Nitrogen was noted for the months of
May - November 2000 and Notice of Violations were sent to the facility.
13. Laboratory records were reviewed for the months January through November 2000 and compared to
Discharge Monitoring Records. Data appeared to be correctly reported.
14. The NPDES permit was available upon request.

-continued-
15. 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, January 2, 2001 at 9:OOAM and the sample is
withdrawn from the composite sampler on Wednesday, January 3, 2001 at 9:OOAM; the day
with the greater number ofhours in it is Tuesday, January 2, 2001.
B If the composite sample is started on Tuesday, January 2, 2001 at 6:OOPM and the sample is
withdrawn from the composite sampler on Wednesday, January 3, 2001 at 6:OOPM; the day
with the greater number or hours in it is Wednesday, January 3, 2001.
