Enclosed is a copy of the Compliance Evaluation Inspection conducted August 20, 2002.
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. Ricky Odum, Grade IV ORC, was appreciated. During the inspection a copy of
the NPDES Compliance Reminders was reviewed and left with Mr. Odum. 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
to contact me at 910-486-1541.

Section D: Summary of Findings/Comments:
1. The facility is 100% domestic wastewater. The source of wastewater is from staff at the industry
(LOF). The City of Laurinburg operates this facility.
2. Influent flow travels through the aeration basins in a series. Diffused aeration is used in the treatment
of the wastewater. Two (2) blowers are used as the aeration source. The blowers are rotated
automatically by a timer.
3. The clarifier appeared to be operating adequately. There appeared to be a few paper products
floating on the water surface in the clarifier. Paper products and debris should be removed to
eliminate possible discharge to the receiving stream.
4. Chlorine gas is added to the effluent for disinfection. The chlorine contact tank appeared to be clean.
There appeared to be some leakage under the V-notch weir. The leakage should be repaired to
eliminate possible short circuiting. Please respond within 30 days of receipt of this report when
weir leakage is eliminated.
5. The effluent appeared to be free of solids.
6. The effluent flows from the chlorine contact tank into the ten (10) acre holding pond located on site.
From the holding pond, the effluent is discharged to an unnamed tributary to Shoe Heel Creek.
7. The sludge digester appeared to have water on the top of the surface. The sludge depth could not be
determined. A determination of the level of sludge should be made to assist with storage. From
records reviewed, it appeared the facility has been wasting every couple of months.
8. The effluent flow meter was calibrated March 20, 2002 by "Jim Haven Company". The flow meter
calibration document should contain the % error before and after calibration.
9. The "Backup Operator" for this facility is Robert Ellis, a Grade IV certified wastewater operator.
10. Maintenance records were reviewed during the inspection. A suggestion would be initial the entries
each day they are made.
11. The NPDES permit required parameters are analyzed by the certified municipal laboratory located
at the Laurinburg Leith Creek WWTP. The facility is utilizing the Hach 100 for Total Chlorine
Residual analyses. A recommendation would be to purchase a new meter to ensure better
accuracy.
12. A compliance evaluation analysis report for the period May 2001 through April 2002 did not reveal
any monthly violations. There were not any NOVs sent from this office for this period.

13. Laboratory records were reviewed for the months November - December 2001 and January - February
2002 and compared to Discharge Monitoring Reports (DMRs). All records reviewed appeared to
be accurate.
