Dear Mr. Darden:
William G. Ross Jr., Secretary
Gregory J. Thorpe, Ph.D.
Acting Director
Division of Water Quality
Enclosed is a copy of the Compliance Evaluation Inspection conducted October 5, 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. Jim Balance, Grade HE 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 have any questions do not hesitate

Section D: Summary of Findings/Comments:
1. The wastewater treatment facility is presently operated by the contract company "Envirolink". Mr. Jim
Balance, who is employed by the company is the " ORC" with a Grade III certification. The "Backup
Operators" are as follows: John Boykin (Grade II), Sandy Wilson (Grade II), and Anthony Branch
(Grade II).
2. The manual bar screen was operational. All screenings are disposed of through the county landfill.
3. The Equalization (EQ) Basin assists in stabilization of wastewater before it flows to the oxidation ditch.
The aerator in the EQ basin was operational. An increase in the slots in the baffle plate to allow further
adjustment to maintain a constant flow 24 hours/day through the plant has been completed since the last
inspection.
4. 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. The lead time for replacement parts
have been investigated and availability would be 4-5 days as recommended. The oxidation ditch
is the heart of the treatment process and the spare parts should be on site or immediately
available to eliminate possible noncompliance with the NPDES permit.
5. The facility is presently analyzing the following parameters to assist with operations as recommended
by Mr. Don Register from our office: Mixed Liquor Suspended Solids (MLSS), Settleable Solids (daily),
oxidation ditch DO, clarifier blanket readings, and the amount of solids wasted in gallons.
6. The clarifier appeared clear as it flowed over the weirs. The sludge depth appeared to be approximately
two (2) feet with a tank depth of ten (10) feet. The weirs and the catwalk appeared to be in need of
painting in the near future to eliminate major repairs in the future.
7. 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.
8. Ultraviolet light is used as disinfection. Ultraviolet light lamps are cleaned every 2 weeks. An intensity
lamp indicator revealed a reading of 2.8 with a range of 0-7. Zero (0) means no disinfection occurring.
A monitor reveals when bulbs are not operating.
9. The effluent appeared to be free of solids. The effluent outfall has been made easily accessible since the
last inspection dated January 19, 2001.
10. The aerobic digester was observed to be operational. A quantity of 1500-3000 gallons of sludge is
wasted daily. Sludge is land applied three (3) times a year to permitted land. The most recent land
application was in June 2001. An amount of 7 ''/ 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 '/2 acres permitted for
land application of sludge. The "ORC" is responsible for land applying the sludge and the farmer
maintains the crop grown on it. It appeared the hay had been cut and bailed recently on the site
surrounding the plant.

11. The effluent flow meter was calibrated September 8, 2001 by Instrumentation Services, Inc. within 2%
error as stated on the report submitted by the technician.
12. 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".
13. A compliance evaluation analysis report for the period August 2000 through July 2001 revealed monthly
violations. Notice of Violations (NOVs) were submitted to the facility for the following:
October 2000 - BOD
March 2001 - Fecal Coliform
June 2001 - BOD.
13. Laboratory records were reviewed for the months January 2001 through June 2001 and compared to
Discharge Monitoring Records. Data appeared to be correctly reported.
14. The NPDES permit was available upon request.
