Section D: Summary of Findings/Comments:
1. Tlie automatic bar screen was operational. There appeared to be numerous teeth missing in the racks
of the bar screen. As a reminder the missing teeth were noted in the previous report dated
February 10, 2000. Please respond to this item in writing to our office by November 30, 2001.
All screenings are disposed of by ARS.
2. The two (2) influent screw pumps were operational. One (1) pump is used under ordinary flow
conditions. The influent pumps are alternated.
3. Flow is pumped from the "Headworks" to a 10 million gallon (MG) equalization basin where it is
continuously mixed. It contains four (4) mixers. All mixers appeared to be operational.
4. The aeration basin appeared to be operating adequately. The aeration basin contains ten (10) aerators
with two (2) under repair at the time of the inspection. Some foam appeared on the surface of the
wastewater but not excessive. The most recent Mixed Liquor Suspended Solids (MLSS) result was 1900
mg/L with settleability around 900 ml/L.
5. Polymer was added in the chemical feed contact area to the Mixed Liquor before it enters the clarifier
to assist with removing color and settleability.
6. The three (3) clarifiers were operational. The sludge depths were less than (<) eight (8) feet with a tank
depth of twelve (12) feet.
7. The final aeration effluent tank where defoamer is added appeared to be operating adequately. The four
(4) spouts which add defoamer to the effluent to reduce foam were operational.
8. The effluent appeared to be free of visible solids.
9. The composite effluent sample refrigerator temperature appeared to be three (3) degrees Celsius. The
acceptable temperature range of samples during storage and for stored samples is 1.0 - 4.4 degrees
Celsius. The sample tubing appeared to be clean.
10. The effluent flow meter was calibrated June 25, 2001 by Nix, Purser and Associates, Inc. It is advisable
that the flow meter calibration document contain the % error before and after calibration in the future
by the technician. The flow chart ink supply was empty so therefor the flow chart could not
document the flow. Please replace the ink immediately to document the flow.
11. The sludge is thickened in a filter belt press from less than (<) one (1) % to five (5)%. The filter belt
press normally operates five (5) days per week. The sludge is land applied by "Synagro" (contract
company) to permitted farm land under permit#WQ0002377.

12. Maintenance records are organized through Preventive Maintenance (P/M) work orders by facility staff.
13. The laboratory on site is certified for eight (8) parameters. All other NPDES permit required parameters
are analyzed by "Microbac Environmental Laboratory" (commercial laboratory) with the exception of
the Toxicity which is analyzed by "Similab".
14. Laboratory records were reviewed for January and February 2001 and compared to Discharge
Monitoring Reports. Data appeared to be correctly reported.
15. A compliance evaluation report for the period September 2000 through August 2001 did not reveal any
monthly violations. Notice of Violations were submitted to the facility for January and March 2001 for
weekly Fecal Coliform violations.

IDED 1 1 2001
This letter :is,in response to your Compliancd`EValuation Inspection conducted on October 9, 2001.
We appreciate your thoroughness and have as in inspections in the past benefited from the comments
and recommendations.
In response to Item 1, Section D, an automatic, in -channel, Dontech bar screen has been ordered to
replace the existing bar screen. This bar screen is scheduled for delivery the week of December 17
and will be installed and fully operational in January.
If you have any questions or need additional information please call me at (910) 369-4111.
