office by October 31, 2003 concerning the items #3 and #5 found in Part D. of this report. The
cooperation of Mr. Jim Balance, ORC was greatly appreciated. As a reminder the preservation of the
Waters of the State can only be acquired through consistent NPDES permit compliance.
Please refer to the enclosed inspection report for additional observations and comments. If you or your staff
have any questions, please call me at 910-486-1541.
Sincerely,
Belinda S.Henson

Section D: Summary of Findings/Comments:
1. The wastewater treatment facility is presently operated by the contract company "Envirolink". Mr.
Jim Ballance, who is employed by the company is the " ORC" with a Grade III certification. The
"Backup Operators" are as follows: John Boykin (Grade II), Ervin Glenn Holland (Grade III),
William Trimmer (Grade II) and Anthony Branch (Grade III).
2 The manual bar screen was operational. An overlay had been added to the bar screen to further assist
with screening of debris since the last inspection. All screenings are placed in a container and
disposed of through the county landfill three (3) times per week.
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. A recommendation would be to repair the
electrical panel located at the catwalk of the EQ basin ASAP.
4. The oxidation ditch appeared to be adequately treating the wastewater. The most recent Settleability
test results were 450 - 600 ml/L. A suggestion would be to analyze the Mixed Liquor Suspended
Solids (MLSS) monthly or more frequently to assist with solids inventory.
5. The clarifier appeared clear as it flowed over the weirs. The sludge depth appeared to be
approximately two and one half (2 '/2) feet with a tank depth of ten (10) feet. As noted in the
previous inspection reports dated October 15, 2001 and September 6, 2002 the weirs and the
catwalk appeared to be in need of painting in the near future to eliminate major repairs in the
future. The facility is wasting approximately 2000 - 3000 gallons/day consistently as per Mr.
Ballance. The Settleability test is utilized to assist with wasting solids from the system.
6. The tertiary filters were observed to be operational. Some grease balls were noted on the surface of
the water but not excessive. The grease balls are skimmed from the water surface each day and
properly disposed of. All backwash water flows back into the EQ Basin or it can be diverted to the
digester if needed.
7. Ultraviolet light is used as disinfection. Ultraviolet light lamps are cleaned every 2 weeks. An
intensity lamp indicator revealed a reading of 4.8 with a range of 0-7. Zero (0) means no
disinfection occurring. UV bank #3 was under repair at the time of the inspection.
8. The effluent appeared to be free of solids.
9. The aerobic digester was observed to be operational. The digester was approximately 1/4 full. The
tank volume of the digester is 56,000 gallons. The most recent land application event occurred the
previous month. Sludge is land applied every two (2) months to permitted land. The Town owns
7'/2 acres surrounding the wastewater facility and it is utilized as a land application site for sludge
disposal. This facility has a total of 44 '/2 acres permitted for land application of sludge as under
permit # WQ0010470. The "ORC" is responsible for land applying the sludge and the farmer
maintains the crop grown on it. The crop bermuda hay had been cut recently and bailed. The bails
were removed at the time of the inspection from the site.

10. The effluent flow meter (OCFIII Open Channel Flow Monitor Greyline Instruments) was calibrated
March 24, 2003 by Instrumentation Services, Inc. within 2% error as stated on the report submitted
by the technician.
11. The facility has a generator on site to power the entire facility when the loss of power occurs. A
suggestion in the future would be to modify the generator to allow low voltage equipment to be
operated during power outages. Presently the generator will only operate high voltage equipment.
12. The following NPDES permit required parameters are analyzed on site by facility staff: pH,
Temperature, Dissolved Oxygen and are certified under #5212. A field inspection check list for the
field parameters was completed during the records review. All other required parameters are
analyzed by the contract laboratory "Vann Laboratories".
13. A compliance evaluation analysis report for the period May 2002 through June 2003 revealed the
following violation: May 2003 - Weekly BOD exceedance.
14. Laboratory records were reviewed for the months October through December 2002 and compared
to Discharge Monitoring Records (DMR). All records reviewed appeared to be adequately reported.
15. All ORC and maintenance records were reviewed and appeared to be adequate.
16. As noted on the day of the inspection Mr. Ballance communicated that September 5, 2003 gasoline
was found in the lift station. The gasoline was pumped out approximately 770 gallons by a
commercial company "Southeast" of Wilmington and properly disposed of.
AS A REMINDER AS PER THE NPDES PERMIT SECTION E. 6.(a) "THE PERMITTEE SHALL
REPORT TO THE CENTRAL OFFICE OR THE APPROPRIATE REGIONAL OFFICE ANY
NONCOMPLIANCE WHICH MAY ENDANGER HEALTH OR THE ENVIRONMENT. ANY
INFORMATION SHALL BE PROVIDED ORALLY WITHIN 24 HOURS FROM THE TIME THE
PERMITTEE BECAME AWARE OF THE CIRCUMSTANCES."

SUBJECT: September 12, 2003 Compliance Evaluation Inspection
Response to items #3 and #5 found in Part D of the Report
Dear Mrs. Henson:
In response to the above mentioned items of the Compliance Evaluation Inspection that was
performed on September 12, 2003, the Town of Newton Grove wishes to make every effort possible to
remediate the items noted. For item #3 in Part D of the report the Town has contacted an electrical
contractor to make the repairs to the electrical box at the equalization basin. These repairs should be
completed in the next few days. For item #5 in Part D of the report the Town is in the process of getting
bids from painting contractors to perform the painting needed at the plant. This will be completed as soon as
this process is accomplished.
It is the intent of the Town of Newton Grove to comply with all local, state and federal regulations
pertaining to the operation and maintenance of its public utility systems. If you have any further questions,
please call meat (910) 594-0827.
Sincerely,
erald Darden - Mayor
