:Dear Mr. Womble:
ern 16'14
NCDENR.
Enclosed is a copy of the Compliance Evaluation Inspection conducted July 20, 2001.
During the inspection a tour of the Wastewater Treatment Plant was conducted. While
discussing effluentSamplecollection, it was discovered that the facility does riot collect composite
samples for the required parameters in the NPDES permit. Please begin effluent composite
sampling within 90 days of receiving this report. All other observations and recommendations
from the inspection are in Part D. Summary of Findings/Comments of this. inspection report. The
cooperation of Mr. Bill Stafford, Grade II ORC was appreciated. 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 haveany questions do not hesitate to
contact the at 910-486-1541.

Section D: Summary of Findings/Comments:
1. The automatic bar screen was operational. It operates by a float system and when the flow reaches a
certain height it operates automatically. A manual bar screen is also in place to utilize when necessary.
All screenings are disposed of in the county landfill.
2. The grit removal system appeared to be operational with all grit disposed in the county landfill.
. 3. A backup generator is on site to provide electricity to the WWTP should an extended power outage
occur. A weekly operational schedule should be implemented to ensure the generator will be operational
in times of need.
4. Barley hay had been placed in the lagoon a few months ago to assist in natural algae control in the
lagoon. Based on studies, chemicals released by the decomposing barley kills or inhibits the growth of
the algae. On the day of the inspection, the clarity of the lagoon appeared to be good with little algae
growth.
5. The multicellular aerated lagoon appeared to be operational. Various areas in the lagoon had alligator
weed in it. The weed should be removed to assist with adequate treatment of the wastewater. The
facility is presently not adding Sonar to the influent for. duckweed control. Some (not excessive)
duckweed appeared in the lagoon. The curtain in cell #4 had been stabilized on the designated posts as
recommended in the inspection report dated August 28.2000. All six aerators were operational. Three
(3) are located in cell #1, two (2) in cell #2 and one (1) in the final cell #4.
6. The chlorine contact tank appeared to be clean. There did not appear to be any turtles located in the tank.
The facility staff continues to use a net to remove creatures out daily to eliminate possible NPDES
permit violations. The facility continues to utilize a water sprinlder system at the discharge outlet to
assist with elimination of foam. The foam did not appear to be excessive. Chlorine is added for
chlorination and sulfur dioxide is added for dechlorination of the effluent. Approximately 20-40 pounds
of chlorine is added per day.
7. The effluent appeared to be free of solids with a slight amount of amber color which is natural for this
effluent with the tannic acid release from tree roots in the area. The effluent discharges into Colly
Swamp. •
8. The effluent flow meter is a Milltronics OCM III which has been installed since the last inspection. The
flow meter is wired through to a flow chart device which records the flows on a flow chart. The flow
meter was calibrated October 18, 2000 as per the sticker found on it. Records confirming the calibration
were not found during the inspection. Please be advised that all flow calibration records should be on
site as part of records retention as stated in the NPDES permit Part II. Section D. 6. Records
Retention. It is advisable that the flow meter calibration document contain the % error of the correct
flow before and after calibration.
9. The `Backup Operator" for this facility is Oliver Worthington, a Grade II operator who is not employed
by the Town.

10. The following NPDES permit parameters are analyzed on site: pH, Temperature, Dissolved Oxygen and
Total Chlorine Residual (TRC). The facility analyzes for the Chlorine parameter with a La Motte 1200.
During the inspection it was discovered that the facility was analyzing for Free Chlorine verses Total
Residual Chlorine. All wastewater samples should be analyzed for Total Residual Chlorine as per
your NPDES permit. The other NPDES permitrequired parameters are analyzed by "Environment 1"
laboratory located in Greenville.
11. Laboratory records for the months September through November 2000 were reviewed and compared
to Discharge Monitoring Reports (DMRs). All records reviewed appeared to be correctly reported.
12. A compliance evaluation analysis report for the period June 2000 through May 2001 did not reveal any
NPDES permit monthly violation for the period.
13. Maintenance records were on site.
Please respond in writing to our office concerning the composite sampling requirement and items 8 and
P by SEPTEMBER 1., 2001.
